The relationship between Betty Cooper and Jughead Jones began as a friendship long before the start of the series and soon advanced to romance.
The two have given each other pet names, 'Betts' and 'Juggy'.
After the Jubilee, they both confessed their love for each other and proceeded to make out. They almost had sex but were interrupted by the Southside Serpents.
The Black Hood forced Betty to breakup with Jughead, or else he would kill him. Betty couldn't bear to breakup with Jughead herself, and asked Archie to do it for her even though it broke her heart. Archie reluctantly agreed, and told Jughead that Betty didn't want to see him anymore. Jughead currently believes the reason that Betty broke up him is because she could see him going down a bad path, and didn't want to go down it with him. Unbeknownst to Jughead, she was doing it out of protection for him, because she truly loved him.
Jughead, alongside Archie Andrews, grew up with Betty in Riverdale. They were friends, but it was not until they began investigating the murder of Jason Blossom that the two started to spend a lot of their time together with the school's newspaper The Blue and Gold, thus starting their romance.
To further investigate what really happened surrounding Jason Blossom's death on the 4th July, Betty reopened the Riverdale High School newspaper, the Blue and Gold and convinced Jughead, and his well-found journalist skills, to join her. For his first assignment, Betty mentioned that there was one person no one had been talking about who was at Sweetwater River on July 4th: Dilton Doiley and his scouts.
Jughead visited Dilton and asked him if he had heard the gunshot that morning. Dilton insisted that neither he nor his boy scouts heard anything unusual on that day. Jughead, upon hearing this, was not convinced. He noticed one of Dilton's scouts eyeing him from a distance and later on, sought out that same scout sitting at Pop's Chock'lit Shoppe who confessed that the gunshot, in fact, originated from Dilton himself, while he was secretly teaching the scouts how to shoot. Once caught, Dilton was willing to compromise with Betty and Jughead. They were to leave Dilton out of the murder case and forget that it had been him who shot the gun, which in exchange, he offered them a better story— Dilton saw Geraldine Grundy's car by the lakeside early that morning.
With the Twilight Drive-In closing, Jughead was furious as the drive-in was very special to him and thought the residents should be trying to save it, which he tried to explain to Betty, Veronica, and Kevin at Pop's. Jughead struggled over which film he should play for the closing night, and he asked the group, who he had already invited to attend, for suggestions. He ultimately went with Betty's: "Rebel Without a Cause." That night while everyone was watching the film, Sheriff Keller's home is broken into and all the files on Jason Blossom's murder were stolen. Come morning it was revealed that Jughead was homeless and had been living out of the drive-in's projection booth, and his father FP Jones, was a member of the Southside Serpents.
At the Blue and Gold offices, Jughead, Betty, and Kevin reconstructed Sheriff Keller's murder board that had been previously destroyed. Unfortunately, the police had no suspects for the break-in, there weren't any fingerprints, and they had no leads. Their conversation was interrupted by Trev Brown, who had come by to confirm a date with Betty that evening, which made Jughead look very jealous. However, after Trev left, Betty said that the date was just a way to get more information on Jason, who had been close friends with Trev.
Betty reported back to Jughead, who wondered, “Why does a rich kid sell drugs?” and what would make him run away from his family so badly? Since they couldn't ask Jason or the Blossoms, they decided to use Jason's memorial as an excuse to dig around Thornhill for clues. Just before they go to Thornhill, Jughead comes round Betty's house to pick her up, and both of them seem to approve of each others attire, although Jughead subtly blushes as Betty 'checks him out'. Following an emotional eulogy from Cheryl, Jughead and Betty snuck away during the commotion and made their way to Jason's room. Unbeknownst to either of them, Rose Blossom, Jason's grandmother, who had been sitting in the dark corner of the room in her wheelchair, startled them. However, she mistakenly took Betty for Polly and unknowingly revealed to them that Polly and Jason had secretly become engaged.
As more secrets from Betty's family came to light, Jughead believed that her parents knew more than they were letting on and wondered how far her they would go to protect Polly. Whoever broke into Sheriff Keller's house was not at the drive-in, and coincidentally, Betty's father hadn't been there that night. With that being said, they added the Cooper family's name to the board and decided the time had come to find Polly.
In an attempt to find out where Polly was hidden away, Betty invited Jughead over for breakfast. Alice accused Jughead of being the reason that Betty was obsessed with the investigation of Jason Blossom's death. However, Betty quickly stated that it had been her idea to publish it in The Blue and Gold. After a look from Betty, Jughead then asked for directions to the bathroom, and as planned, Alice escorted him, which provided a long enough distraction for Betty to go through her mother's purse and take photos of her check book. At The Blue and Gold, after doing a little digging, Betty and Jughead discovered one of the checks were sent to the Sisters of Quiet Mercy, a group home for troubled youths.
During lunch, they quietly discussed Polly and their next course of action, which was catching a bus to the group-home to find her. They found Polly, and Betty was surprised to find that all the information her parents were telling her, was just to cover up for the fact that Polly was pregnant with Jason's baby. Unfortunately, Betty and Jughead were caught by Alice and were forced to leave.
After she returned from the institution, Betty was alone in her room when Jughead knocked on her window after climbing up a ladder. She smiled and opened the window to which he quipped, "Hey there, Juliet", before climbing in. After a brief conversation, Betty confided in Jughead about her feelings towards her parents, sister, and even herself. He calmly helped her through it and told her that she is not her family. Jughead then kissed Betty, to which she smiled and he deeply exhaled, before Betty remembering that earlier Polly had told her about a car Jason had kept for them out by an old maple farm sign on Route 40 and it might still be hidden there, to which Jughead is humorously shocked that she changed the subject so quickly.
That night, they found the car, hidden under a tarp and filled with Jason's things, including his varsity jacket, as well as plenty of drugs. They took pictures and alerted Sheriff Keller, all the while as they were unknowingly being watched by someone hidden in the woods. The authorities arrived only to find the vehicle had been set on fire. Jughead and Betty then raced to rescue Polly from the group home but found that her room was empty, the window broken and blood coated the glass.
After being forced out of the drive-in, Jughead secretly moved into Riverdale High, taking over a small forgotten closet under a staircase, where one morning he dreamed a strange 50s style dream in which he is married to Betty, Jason Blossom is alive and the Coopers are loving parents who approve of both their daughters relationships. In the dream, the family as well as Veronica and Archie were sitting down to a big turkey dinner and as Jughead started to carve the bird, the knife disappears from his hand. Archie then walked up and calmly asked, "Dude, why'd you stab me in the back?" before turning around, the carving knife embedded between his shoulder blades. That same morning his living situation is found out by Archie. Jughead then asked him not to tell anyone, especially not Betty, which confused Archie who wondered why Betty would care.
Later on, the gang met up in the student lounge and discussed Polly’s escape from the group home. Betty became stressed and clearly worried about how Polly could be hurt and how the person who killed Jason could be after Polly too. To comfort her, Jughead put his arm around her shoulder and Betty reached to hold his hand, which surprised Veronica and confused Archie. Archie caught up with Jughead in the hall afterward and asked if there was something going on between the two of them and Jughead hesitantly replied that they may have had a moment. Flustered, Archie cuts him off and changes the subject, clearly not happy with the answer he got. At the other end of the hall, Veronica also asked Betty about Jughead and Betty smiled and gushed that Jughead had really been there for her through the trouble with her family the past few days. Veronica was excited for her and gave her approval.
To find Polly, Jughead and Betty organized a search of Eversgreen Forest together, which was interrupted by the Blossoms and ultimately unsuccessful. As Jughead walked her home afterward, holding hands, he struggled to define their relationship. Betty was upset that there was no luck finding Polly and worried that she should not have told Polly about Jason’s death, that Polly could be hurt because of it. Jughead reassured her she did the right thing, that it was her parents who were the ones in the wrong for keeping the truth from Polly. Betty then told him how Polly once ran away before when she was nine after a big fight with their mother, Jughead asked how far she got, which led to her realizing where Polly had gone to hide. Thankful and excited, Betty kissed Jughead and said goodnight before quickly rushing home, as Jughead smiled all the while. At the Cooper House Betty found Polly hiding up in the attic.
Later that night, Jughead, Archie, FP Jones and Archie's dad went to dinner at Pop's and Archie brought up Jughead’s work at The Blue and Gold with Betty. Jughead’s father asked if Betty was Jughead’s girlfriend, which Archie looked very interested to find out the answer to, but Jughead not wanting to tell anyone about his and Betty's situation, swiftly changed the subject. Archie then looked taken aback and a bit jealous.
The next morning Jughead was brought to the Sheriff Station by Sheriff Keller as a suspect for Jason's murder. His and Betty’s fingerprints were found on Jason’s torched car as expected, but Jughead had a surprising juvie record from six years prior when he almost burned down Riverdale Elementary School, which, according to Jughead, was an accident; he was just playing with matches. Sheriff Keller unfairly suspected him as the killer due to his background and being from the 'wrong side of the tracks'.
Betty was allowed to speak to Jughead alone after his interrogation and held his hand while she reassured him that she believed him, that she knew who he was. Betty promised him that she would not let anything happen to him. She also told him that his father had been called but no one knew where he was. Jughead was released after Fred Andrew’s lied and told Sheriff Keller that Jughead was tearing down drywall for his construction company on July 11th, which Fred and Archie later falsified a time-card to prove it.
Jughead’s father showed up to the station just as everyone was leaving and caused a scene in front of Fred, Archie and Betty. Jughead convinced him to let it go and before he left, FP promised he would get his act together and that they would have their family back, it would just take some time. Jughead looked angry and resigned as he told his father he believed him. Betty placed her hand on Jughead’s cheek and comforted him as they left the station and once again Archie looked jealous. In the end, Jughead went to live at the Andrew’s house.
The next day, in the student lounge, Jughead, Archie, Betty, Veronica, Kevin, Cheryl, and Valerie analyzed Polly's dilemma, in which the Coopers wanted her but not the baby, and the Blossoms wanted the baby, but not her. A true Gordian Knot, Jughead said. However, Veronica disagreed, it was a fairly solvable problem, she suggested that they throw Polly a baby shower at the Pembrooke where Polly had been staying, which would force the Coopers to finally start communicating. Jughead inquired whether he would be expected to attend and Veronica immediately replied yes, because he was Betty's boyfriend. Betty and Jughead then shared a smile.
After Moose Mason was attacked while helping out at Andrews Construction, Jughead filled Betty and Veronica in on the attack at Pop's shoppe, in which he assured them Moose was fine. Just then, Archie entered the diner, seeking Jughead's help as he, Moose and Kevin planned on finding the supposed Serpents that attacked Moose. Kevin's boyfriend, Joaquin DeSantos, who was also a Serpent, could get them into the Whyte Wyrm, a known hangout for the gang. Betty wasn't too sure that it was the best idea since the Serpents were dangerous drug dealers; the drug dealer portion of that comment being confirmed a day earlier as Polly informed them that Jason was dealing for the Serpents. Jughead insisted that going into the bar was a terrible idea, but all Archie wanted to know is if Jughead would join him, which he didn't, and Archie went without him.
Jughead and Betty shared a kiss as the baby shower began, she thanked him for being there since that event wasn't his usual kind of scene. Jughead sarcastically replied that "organizing a baby shower was totally on his bucket list", making Betty smile. During the gift portion of the shower, Archie unexpectedly showed up and angrily confronted Jughead on his father being a Serpent and the reason he tried to prevent them from going to the bar. As the baby shower came to a close, Jughead explained that he was ashamed of his father's affiliations, which is why he hadn't told anyone, which Betty immediately forgave him for, and then suggested that they pay FP a visit and ask about Jason.
At the trailer park with his father, FP claimed they gave Jason some product to deliver upstate, but when it never showed, they assumed he had run off with it until his body showed up at Sweetwater River. Jughead then asked his father if he had any involvement in Jason's death, despite FP being his father, it was the dark ages, he didn't know what to think. FP admitted that he was a lousy parent, but he insisted that he wasn't a killer. Outside the trailer, Jughead told Betty that he believed his father, and she believed Jughead, the two of them then shared another kiss.
After Polly went to live with the Blossoms at Thornhill, Betty and Jughead discussed why she had stopped returning Betty's calls in her bedroom. She understood Polly not speaking with their father but what had she done? Jughead assured her that they would figure it out and they briefly kissed before Alice interrupted and announced she was writing a no-holds-barred exposé on the Blossom clan.
In the student lounge at school, Archie informed the group that Penelope Blossom offered to put in a good word for him at a prestigious music academy in exchange for him escorting Cheryl to her family's annual tree tapping event. Jughead didn't think it was a good idea, but Betty disagreed and asked him if he could use the opportunity to speak with Polly on her behalf. Unfortunately, after the event, he informed Betty that Polly wanted her to stop trying to contact her. Disregarding Polly's message, Betty and Jughead asked Cheryl to talk to her sister for her who informs them that Polly would be having twins. Saddened that Polly hadn't called to tell her the news, Betty once again asked Cheryl to give Polly a message, to call their mom. Cheryl joked that she would if she remembered, but Jughead quickly stepped in and Cheryl agreed to send the message along but made no promises that Polly would care or respond.
The next day, in The Blue and Gold offices, Betty dejectedly told Jughead of an occurrence between her parents the night before, which ended with her mother throwing a large rock through The Registers glass door at her father. Extremely upset, Betty began to cry as she expressed the thought of her family falling apart, and there not being anything she could do to stop it. Jughead attempted to encourage her, claiming that she was much stronger than both her parents, strong enough to hold her family together. With tears in both their eyes, he told her not to give up. Betty promised she wouldn't and they hugged each other tightly.
After a call from Archie, Betty and Jughead went to see Alice at the Cooper house and happily informed her that Polly was safe and that she had not deserted them, but had actually chosen to live with the Blossoms in order to spy on them and discover more about what happened to Jason. Alice was relieved and overcome with emotion as she believed she might have lost Polly for good. Betty assured her mother that Polly would come home and that they would be writing their story on the Blossoms with Polly as their woman on the inside. Jughead then asked Alice to join them at the school newspaper. Later, Archie informed Betty and Jughead of what else he had found out about the Blossoms: Clifford Blossom might have been responsible for sending Hiram Lodge to jail. Jughead posited that perhaps Hiram had taken his revenge by killing Jason and added his name to their murder board.
From Archie, Betty learned that Jughead's birthday was coming up and that every year the two of them went to a movie, but considering that Betty was his girlfriend now, Archie thought it best if she took him. She agreed and called Jughead's father to see if he would join them, however, he declined and told her that the one thing Jughead liked less than surprises was his birthday, he had never had nor wanted a birthday party. At lunch, Betty suggested to the group that they throw him a low-key surprise party. While initially reluctant, knowing Jughead's feelings, Archie agreed. Refusing to take no for an answer, Betty visited FP at work to invite him as she thought it would be very special if he attended. Later, Betty asked her mother if she had told her father everything about herself when they first started dating. She did, but Alice came to regret doing so as Hal had used everything against her in the end. Betty stated that she trusted Jughead, however, despite her mother thinking that that was good, she did not think she should trust him with everything.
The following night, as planned, Betty accompanied Jughead to the Bijou, where he asked her about a confrontation she had had with Chuck Clayton the day prior. However, Betty merely stated that it was nothing worth getting upset over. Afterward, they returned to the Andrews house and the party that awaited Jughead, who was caught completely off guard. Betty brought out Jughead's birthday cake and sang him happy birthday before he blew out the candles, he quietly remarked that he wished it was only the two of them at the house. Then they entered the kitchen to find Archie and Veronica hugging, to which Veronica revealed she wasn't in a partying mood. Jughead stated that she wasn't the only one and told Betty that, while he appreciated the sentiment behind her throwing the party, he would rather it was just the four of them sitting in a booth at Pop's. Betty then questioned why he couldn't be normal just for once, but he replied that he wasn't normal nor was he wired to be. They were then interrupted by Cheryl and Chuck, along with several dozen uninvited classmates eager to party. Jughead retreated to the garage where he was found by his father, much to Jughead's surprise. He questioned if Betty had called him, and FP admitted that she did, that Betty knew what she wanted.
Jughead later confronted Betty over inviting his father to a party with alcohol, while knowing he had a drinking problem, but Betty claimed that it was only supposed to be a party with his friends. Frustrated, Jughead became increasingly upset over Betty not caring how he felt. He wondered if it had ever occurred to her how different they were; Betty, a straight-A student, a cheerleader and the perfect girl next door, while he was the damaged, loner outsider from the wrong side of the tracks. He believed they were on borrowed time, suspecting that she was only with him until Archie changed his mind and wanted to be with her. Shocked, Betty left, with tears filling her eyes. As he Jughead attempted to leave the party, he was cut off by Chuck and Cheryl, who insisted that everyone play a game Cheryl called called "Secrets & Sins", during which Chuck revealed exactly what had happened the night Betty and Veronica got him to confess to slut-shaming. He told everyone that Betty dressed up like a hooker in a terrible black wig, drugged and handcuffed him to in a hot tub and threatened to drown him until he said what she wanted to hear. Shocked and angry, Jughead got into a fight with Chuck in Betty's defense, which was ended by FP. As Jughead attempted once again to leave, FP told him to stay as what he had with Betty and his friends was something his family could never give to him. His father then told to man up, because after what FP saw go on, Betty needed him.
He and Betty reconciled over milkshakes at Pop's, where Jughead admitted that Betty was doing something nice for him, but he was scared of being rejected for being himself. Betty then admitted that she should have told him the truth about Chuck instead of throwing a party he did not want. He wondered why she hadn't and she opened up about what she called a "darkness inside her" that made her do such horrible things, showing him the marks on her palms from digging her nails in deep. His look softened, and he gently kissed her hands. Betty then kissed him, before resting her head on his shoulder, happy that they had made up.
Betty's mother suspected Hiram Lodge to have hired FP Jones for the murder of Jason Blossom. Betty confessed that she was completely against it and that she would not betray Jughead by entertaining her mother's interrogation, She then walked out.
Later, Jughead walked in entered the gymnasium, while Betty was decorating the hall for the Homecoming dance asking about the dinner before Homecoming that her mother had practically tackled him in the hallway to invite him and his father to. He excitedly told her that her mother had earlier invited him and his dad for dinner at the Cooper's house, indicating how it was about time their families got to know each other. Betty was completely unaware of the dinner, but she lied, claiming she did as Jughead was so happy about it. Betty returned home to confront her mother on the obvious trap she was planning for FP, to interrogate him about Jason's death. Betty wasn't willing to play this game with her, and neither would Jughead once she told him the truth but Alice told him that would be unwise as Jughead was excited about their families getting to know each other, and with this in mind, Betty told Jughead nothing.
Betty confronted Alice, stating that she knew what her mother was up to and that she wouldn't be part of the game she is playing, to which she defended saying that she took Betty's earlier words to heart. Betty told her that Jughead will soon find out what she was up to but doesn't tell him anything when her mother explains how Jughead was really excited to attend and promises she won't interrogate either of them.
The following night, just as planned, Jughead and his father had dinner with Betty and Mrs. Cooper and the interrogation began almost immediately, which Betty attempted to put a stop to but to no avail. Alice practically interrogated jughead's father on his involvement with the Southside Serpents and his spotty work history. The doorbell rang, it was Betty's father, Hal Cooper, which only made the situation worse, leaving Betty with the only option of ending the dinner, and leaving for the dance with Jughead and FP.
After an amazing performance by Archie and Veronica, Jughead joined them and Betty in the hallway, where they revealed their treacherous actions of breaking into his father's trailer in search of any evidence that would prove him to be Jason Blossom's Killer. Alice put them up to it, and they knew when to go because he would be at the dinner, which led Jughead to believe that Betty was also in on this treachery, leaving him to question why he would ever pass on moving with his family to Toledo for her.
Later, After the discovery that FP was arrested for the murder of Jason Blossom, Betty and her mother returned home, where she questioned if her mother was the one that tipped off Sheriff Keller. Alice promised it wasn't her, and as much as she liked Jughead, she was happy Betty was done with the family, but Betty proclaimed that she loved Jughead, and he was as much her family, as Alice was, more so at that moment. She told her mother not to push her, or else she would push back, then leaving to find Jughead. 
After searching all over town for Jughead, Betty, Archie, and Veronica found him in the only place he could be during that time of night, in a booth at Pop's. Betty sat next to him, apologizing for their betrayal. However, some good did come of Archie and Veronica breaking into FP's trailer. They knew with the up most certainty that the gun wasn't there when they searched, meaning someone planted the weapon in FP's closet after they left. Betty, Jughead, Archie, and Veronica headed to the Sheriff Station to inform Sheriff Keller that FP was being framed for Jason's murder. However, with FP having already given his confession, there wasn't much they could do.
Despite his initial decision to stay home that day, Jughead showed at school, where he was attacked by Cheryl while simply trying to apologize for his father's actions. In spite of Cheryl being the aggressor, Jughead was carted off to the principal's office by Mr. Weatherbee, where Betty waited outside while he was interrogated for the second time that day. Jughead exited the office, telling Betty that he doesn't know whose more of a dick between Sheriff Keller and principal Weatherbee, his two interrogators. Betty insisted that he ignore them. Everyone else was wrong, and they simply needed to prove it. If not FP, then who killed Jason, Jughead asked. Its difficult to ignore the fact that FP confessed to the murder. Jughead had been waiting his entire life for his father to do the right thing, but now he's tired of waiting, as should Betty.
The next day, after visiting his father at the station, and calling Betty to admit that she was right about FP hiding something, Jughead and Betty convened at the Blue and Gold offices. His father has been lying to him his entire life, but he's never been any good at it. Jughead could see in his father's eyes that he was innocent of killing Jason Blossom. What they needed to figure out is who he was protecting by confessing to the murder that he did not commit. From there, they began to rule out suspects, removing their photos from the murder board as they did so, starting with Betty's father. They know the reason for his strange behavior was due to the blood feud between her family and the Blossoms. Hermione Lodge was the next suspect to be ruled out. Veronica said that she was guilty of plenty, but not murder, not to mention her alibi places her in New York at the time of Jason's murder. That left Hiram Lodge, as well as Clifford and Penelope Blossom.
Before long, they are joined by Alice, who wasn't too surprised by their inability to leave the case alone. From Alice they learned that the police found another dead body, a Southside serpent name Mustang. Sheriff Keller is convinced that he was working with FP. He allegedly committed suicide via overdose, and there was a bag of money found nearby with Hiram Lodges initials. Like Betty and Jughead, Alice suspected foul play as everything was too tidy for her liking. Betty then received a call from Kevin, telling her and Jughead to meet him on the highway off route 40, where they found Jason's abandoned car. Whatever it was that they were looking for, Joaquin didn't know if it would help FP or make it worse. Betty questioned why it took him until now to speak up. According to Joaquin via Kevin, FP called him from Jail, and told him to forget about their contingency plan as it was too dangerous. Hidden underneath a pile of branches just behind the old Blossom Maple Farms sign was a duffel bag. Inside, Betty, Jughead, and Kevin discover Jason's varsity jacket.
Confused by their latest discovery, Jughead, Betty, and Kevin headed over to Archie's garage, where they discussed their next course of action, and what finding Jason's varsity jacket could mean. It certainly confirmed that FP torched Jason's get away car. Betty began to wonder why FP would say that the jacket is dangerous. Veronica then joined them in Archie's garage. She claimed that they found concrete proof that her father hired the serpents to kill Jason, which likely meant that FP pulled the trigger. Despite all odds being against them, Betty refused to give up. She forces Archie to put the jacket on while she searched the pockets. She noticed a hole in one of the pockets. Whenever she had a hole in her jacket pocket, she always lost her chap-stick in the lining. As Betty dug deeper, she discovered a USB flashdrive in the lining of the jacket. They insert the USB into a laptop. What they see is far worse than they expected. The USB contained footage of Jason Blossom's death, in which he was shot in the head by his own father, Clifford Blossom.
Betty turned down Mayor McCoy's offer to be honored at the 75th Anniversary Jubilee for her hand in solving Jason Blossom's murder after the Mayor refused to honor Jughead as well. Despite Jughead having arguably the biggest role to play in solving Jason's murder, Mayor McCoy though it best to not have him on stage considering his father's role in Jason's death, in which he disposed of the body. While Jughead appreciated Betty's righteous indignation, Jubilees weren't the type of events he would attend anyways. Back on the subject of his father, Mayor McCoy wanted FP to give up names of the serpents in exchange for a lesser sentence. Sheriff Keller believed that they were responsible for the recent increase in drug trafficking, but FP insists that they aren't responsible for the dealings. Meanwhile, Mayor McCoy hasn't even mentioned Clifford Blossom's name. Betty didn't appreciate that the serpents were being villainized for a crime they did not commit. She decided then and there that she would write an article on the subject for the Register as the story was town-wide. Jughead was fine with this so long as it didn't include his father. But as Betty explained, it would involve FP. It doesn't matter how many Jubilees Mayor McCoy throws, the town has changed, and that needed to be acknowledged.
The next day, after Betty had published her article pertaining to the unfair treatment that FP and the serpents were facing, her locker was vandalized with a message written in pig's blood, "Go To Hell Serpent Slut!". A Betty doll was also hung from a noose. Jughead stepped in front of the locker as she attempted to undo the vandal's work. She tried to push past Jughead, but he pulled her close, and the two of them hastily left the scene. As long as Betty was with him, and continued to write articles about his father, trouble would continue to come at her from all sides. She repeated her earlier statement of it being one jerk, but Jughead begged to differ. Its Mayor McCoy, Sheriff Keller, Weatherbee, social services, and the entire multiverse telling him that he doesn't belong, so maybe he should do everyone a favor by leaving. Betty stopped Jughead. She caressed his face while telling him that he belongs in Riverdale just as much as everyone else.
Jughead called Betty the next day to inform her that he had transferred to Southside High. He was where he belonged. He would like to continue the discussion after school, then telling Betty not to worry about him before hanging up. Betty refused to allow Jughead to leave, and distance himself from them. So, Betty, Archie, and Veronica took it upon themselves to bring Jughead back from the south side. Much to their surprise, Jughead was fitting in well at his new school. Betty, Archie, and Veronica found him having a good time in the cafeteria with a few of the other students. Betty and Jughead stood just outside the school, where they could talk in private. He didn't tell Betty that he was leaving because he knew that she would try to stop him. Betty admitted that he's right, and that she hasn't given up trying. Jughead explains that the south side is where the power to be wanted him. Maybe he wanted to be at South Side high as well. He blended in better at his new school, and it would keep Betty safe, though she wasn't willing to let Riverdale Civil War split them apart. They then share a hug before learning that Cherly was in trouble.
Betty, Jughead, Archie, and Veronica headed out to Sweetwater River, where Cheryl attempted to kill herself in order to reunite with Jason. However, the water had frozen over, which forced Cheryl to pound on the ice repeatedly. Betty spotted her towards the middle of the river. They called out to her, and pleaded with her to stop, though they could not travel onto the ice as too much weight could send them all under. However, once the ice broke, and the current pulled Cheryl under, the four of them were forced to run on the ice, and search for her. Archie found Cheryl a little further down the river, just beneath the thick layer of ice. Betty, Jughead, and Veronica stand by as he pounds through the ice, pulling Cheryl out, and performing CPR on her, before returning to shore.
That night, Jughead entered the Jubilee as Betty gave her speech. Riverdale was the people of their town, up to and including FP Jones, who they had quickly blamed, and written off as Jason's killer. Jughead was also Riverdale; the very soul of Riverdale. Without him, they may have never found out what truly happened to Jason, yet they repay him for his actions by banishing him, which is what they do when the truth becomes to difficult to withstand; the truth being that Clifford Blossom was also Riverdale. Their town was at a crossroads. Should they continue to ignore the reality of who and what they are by lying to themselves and keeping secrets from each other, then what happened to Jason could happen again, or even worse. She closed her speech with "Riverdale must do better. We must do better". Jughead gave her a round of applause. The crowd joined in soon thereafter.
After the Jubilee, and many rounds of milkshakes between Betty, Jughead, Archie, and Veronica at Pop's shoppe, Betty and Jughead stopped by the trailer, which was much cleaner in comparison to the last time Betty was there. Jughead cleaned it up after Sheriff Keller trashed it, just in case his father ever does get released. Speaking of which, Betty had no intentions on giving up on FP, which is precisely why Jughead loves her. And while his out-pour of love took Betty by surprise, she loved him as well. The two of them began kissing and undressing until they are interrupted by loud knocking at the door. They initially assumed that it was Alice, however, Jughead opened the door to the sight of the Southside Serpents, who came to offer him membership into their gang after learning that FP stayed loyal to them. One of the Serpents tossed Jughead a leather jacket with the gang's double-headed serpent symbol on the back. Betty watched from the doorway as put the jacket on.
After Archie's father was shot, and taken to Riverdale General Hospital, Veronica arrived and spoke to Jughead and Betty, where she informed them that Archie was back at the police station, attempting to identify the shooter with a lineup. Betty then told them that they all should go and be with him, as it would be traumatizing for Archie to be there alone. Veronica interrupted Betty, asking her if they could, instead, do her a favor. Fred's wallet was missing, Veronica and Archie thought that it might still be back at Pop's. His wallet was either there, or maybe in possession of the shooter. Betty suggested that the gunman probably took his wallet for the cash. Jughead offered a more distressing theory; what if it wasn't just a robbery and was a hit instead. This coming from the fact that Riverdale was also the place where fathers kill their own sons, in reference to Cliff and Jason Blossom. Adding that people have grudges, he believed it was possible that it was a hit. Betty reassured Veronica that the wallet could still be at Pop's and told her that they'd go check it out. Jughead and Betty left the hospital on Jughead's motorcycle.
In the search for Mr. Andrews' wallet, Jughead and Betty arrived at the diner, where they ran into Pop Tate. They had a brief conversation with him as to what happened back at the diner after Black Hood had shot Fred. Pop told them his version of what happened and about the mysterious man under the mask. With the story complete, he asked them if they were hungry and would like something to eat; he could use the company while he was still shaken up from the incident. Jughead indulged in his burger and fries as since he hadn't eaten since last night, while, on the other hand, hadn't touched her food. He tried to make a joke to brighten up the mood, but to no avail. Initially reluctant at first, because of Fred's current condition and the tragic event at Pop's, Betty decided to voice her concern about Jughead growing closer to the Serpents. While Jughead denied the fact that him putting on the Serpent jacket didn't mean anything as he couldn't reject their offer in front of ten biker dudes, Betty retorted that the look on his face showed that he wasn't acting for the Serpents. Betty noted it fit him like a glove, like a "second skin" and the fact that he put on that leather jacket, meant something.
He told her that it may have been his father's life, but it wasn't his. However, Betty was not convinced, pointing out that his foster family was also from the Southside, if they also had ties to the Serpents, they could try to indoctrinate him. He reassured Betty that she didn't have to worry, that he worked out a plan with his foster family where he could still live in his father's trailer home, while they covered for him with his social worker, because, much like wearing the Serpent jacket and riding his father’s motorcycle, it was a way for him to feel close to his dad, no matter what. Betty understood but warned him about getting too closely tied with the Serpents as she didn't want to see him get hurt, or end up hurting someone else as it was the Serpents' nature in doing so.
Later, back at the hospital, the gang sat together at the hospital cantine. While Betty, Jughead and Veronica commented how well Archie was tackling the situation, he didn't look convinced. Noticing this, Veronica asked Archie that he could talk to them. Sighing, he commenced telling them part of the story that he left out because he felt so ashamed; after the guy fired at his father, he should've retaliated or rushed to his father immediately, but instead stood there paralyzed. Even when the shooter walked up to him and pointed the gun at his head, he didn't move and chose instead to close his eyes, long enough for the shooter to possibly steal Fred's wallet. He didn't open his eyes until he heard the bell of Pop's Chock'lit Shoppe ring. As Betty tried to reassure him that there was nothing he could've done, Archie admitted in shame that he was a coward, because he had a chance to comfort his father or tackle the shooter. Now, him and his father, are now witnesses, as well as Pop Tate, too. Telling them fearfully, what if he came back?
Afterwards, Betty and Jughead were at the back of the hospital building, where it was raining outside. Jughead offered if she was sure that she didn't want him to give her a ride back home. Betty joked that if her mom ever saw her getting off the back of his motorcycle, she'd probably come out with a shotgun. Mused, Jughead agreed with her and they both laughed at the thought. Before Jughead left for his bike, Betty stopped him. She told him what he told her back at Pop's. She was listening to him and told him that she understood his situation and how he was feeling. She also told him that whatever it was that he needed to do or explore, she would support him. They then embraced in a kiss before Jughead left.
After Finding out that his father, FP, would be in prison for the next 20 to 40 years for his crimes. A worried Jughead was seen, as he hoped for his father to not have such a harsh punishment. Determined to help his father, Jughead found a loophole out of his father's punishment. Which was, he had to get the Blossom Family to make a statement, stating that they forgave FP for his part in Jason's murder. Jughead later headed over with Betty to the Thistlehouse, where Cheryl and her mother, Penelope where staying. To convince them to make a statement that would help in FP's case. However, the Blossom's were reluctant to do so, Refusing to help Jughead. As Penelope and Cheryl wanted FP to suffer for what happened to Jason. As Betty later pointed out to Cheryl that it wasn't FP who killed her brother, it was her father.
Later, Betty stopped by the girls' locker room, as she came by to have a chat with Cheryl. Betty blackmailed Cheryl into testifying on the behalf of her family for FP's court trial, without Jughead knowing about it. As she threatened Cheryl that she would show every one of the copied footage that was made an kept on Jughead's laptop, of the night her father, Clifford, killing Jason in cold blood. Ashamed of her father's sins, and how it would impact her and her mother, Cheryl was willing to make her statement to prevent the footage from getting out. Back at Pop's Retro Night is a success and Betty was able to "officially" save the Pop's from closing.
Betty is determined to not make the distance of schools a problem that will affect their relationship and visits Jughead at the Red and Black, Southside High's school newspaper. They share a tender kiss, which was not long before being interrupted by Toni Topaz; Jughead's new friend.
Later, after Betty's Visit, Jughead stayed late at the Red and Black, finally finished cleaning up the place, setting it up for him to start writing. However, on his way home, he was beaten up by the Ghoulies. The next day, at his home, Betty cleaned up his bruises, believing that he fell off his motorcycle, which was an excuse Jughead used instead of telling her the truth. Toni, however, knew what really happened, but knew Jughead wanted to keep it a secret, so instead, she honored his wishes due to her loyalty towards him.
Betty met up with Jughead, at Pop's, where she greeted him with a kiss. She was a sight for sore eyes, Jughead commented. They'd both been feeling unmoored recently. Jughead wanted to check in with her after the exposé of her mother that she published, with a mugshot from many years ago, of her mother's arrest as a young member of the Southside Serpents. While it was intense, it was also a long story that Betty chose not to dive into at the moment. Betty then asked about Jughead's hand, after noticing that it was wrapped in gauze. He claimed that he sustained the wound while dogsitting Hot Dog. Sitting on opposite ends of the table, holding each other's hands, Betty and Jughead both wished that they could leave Riverdale on his motorcycle for someplace where there wasn't a brewing war between two sides or crazy moms and psychotic killers. They'd be like Romeo and Juliet, Betty imagined, but with a happily ever after instead.
As Black Hood had been threatening Betty to do deceitful acts through phone calls, Betty was forced to break up with Jughead or he would kill Polly and Jughead. So Betty, in tears, met Archie at the Blue and Gold offices to tell him of recent developments with Black Hood. She confessed that she lied earlier about Black Hood contacting her again and told him that Polly's life was threatened if she didn't break up with Jughead. Upon hearing this, Archie was reached for his phone, about to call someone, but Betty insisted that no one know. She then asked Archie to tell Jughead that she has broken up with him, telling him to make something up, something believable that would make Jughead stay away, for a while at least, hoping they could undo the damage later. Reluctant, Archie decided upon complying with her wishes.
However, when Archie went to deliver the news, the Serpents had arrived for the final stage of Jughead's initiation. Overcome by anger that Jughead was becoming a Serpent, he made matters worse by hurting Jughead more than intended, who later, unbeknownst to Betty, shared a kiss with Toni in FP’s trailer.
Before the Riverdale Drag Race, Betty is fixing the car that Jughead and Archie will ride to win against the Ghoulies. Betty attempts to make conversation with Jughead after their forced breakup. Silence is prevalent for only a few seconds until Jughead tells Betty to say what's on her mind, which is that Jughead told her he wouldn't join the Serpents. He counters that by saying that she said he loved him, and then she dumped him. She sincerely apologizes, saying that she broke up with him in order to protect him, as everything around them was imploding. Betty continues, saying that she'll tell him everything, but after she helps him through this race first. Jughead scoffs and turns his back to Betty once again.
In the trailer, Jughead and Betty are cuddling, as she's reading a book, and Jughead is writing his ongoing book about Riverdale. It is revealed that Betty came clean to him about her "dance macabre" with the Black Hood.
