I'm gonna get you out of here, I swear to God. I love you, Polly!
— Betty to Polly[src]

The sister relationship between Betty and Polly Cooper is close. Who are the daughters of Hal and Alice Cooper, and are very close. After being separated by their parents for a long time, the two finally reunited after Betty and Jughead found out where Polly had been forcibly sent by her parents, which is where Betty discovered that her sister was pregnant with Jason's child.

History

During their childhood, Betty and Polly shared a close bond with one another that remained as they grew up. However, they were separated when, according to their parents, Polly suffered a breakdown due to the collapse of her relationship with Jason Blossom and was subsequently sent to a group home. Their parent then refused to tell Betty where her sister was, that she was too sick for visitors, and told Polly that Betty didn't want to see her.

Throughout Riverdale

Season 1

Since her parents wouldn't tell her where Polly was, Betty enlisted the help of Jughead Jones to help find her. She wanted to see her and also needed to question her about Jason. Betty invited Jughead over for breakfast with her mother one morning and while Jughead distracted Alice, Betty searched her mother's purse and found a check made out to the Sisters of Quiet Mercy, a home for troubled youths.

When she arrived at the group home, she found out that her sister wasn't the crazy person her parents made her out to be, in fact, Polly was pregnant with Jason's baby. This all now made sense to Betty as to why they kept Polly away all those months. Polly explained that she and Jason had planned to run away together, they had a car stashed away ready to go, but Hal and Alice found out and sent her to the Sisters the same day they were meant to leave. It was also revealed that Polly had no idea Jason had been killed and Betty was forced to tell her the truth. Polly and Betty's reunion didn't last long however, as Alice had been notified that Polly had received visitors and arrived to take Betty back home.

Season 1 Episode 6 Betty Polly

Betty promises Polly she'd get her out of the group home.

As Alice, Betty and Jughead were leaving the facility, they encountered an angry Polly who briefly confronted her mother about Jason. Polly was dragged away by two orderlies but not before Betty made a promise that she would get her sister out of there. That same night, Betty and Jughead found the car of Jason's that Polly had talked about, however, after notifying the Sheriff of it's existence, found someone had set the car on fire while they were away. They then returned to the group home to retrieve Polly only to find she was already gone; escaped through her bedroom window. [1]

To find Polly, Jughead and Betty organized a search of Eversgreen Forest, which was interrupted by the Blossoms and ultimately unsuccessful. On the walk home from the search with Jughead, Betty realized where her sister was hiding—the attic at the Cooper house. She had hidden there once before when she was little. Betty indeed found Polly, who explained that she couldn't stay at the group home, waiting for Jason to show up since she knew now he never would. Polly and Jason initially had a plan to move to a farm upstate and raise the baby and Polly still wished to go there as their parents were pressuring her to give the baby up for adoption, but she didn't have the money to make it. Polly remained in the attic as Betty tried to think of a solution, and ultimately sought help from the Blossoms. Cliff and Penelope Blossom assured Betty that they would take care of Polly and the baby, however later on, Cheryl revealed that they cared only about the baby and Polly would not be safe with her parents. With no place else to go, Veronica and Hermione Lodge allowed Polly to stay with them.[2]

Free of outside control, Polly was interviewed by Sheriff Keller about Jason and the plans they'd made at the Lodge's apartment at The Pembrooke, Betty by her side. The interview had to be cut short, however, as Polly became upset. Betty comforted her sister and reassured her that she would get through this.

Season 1 Episode 8 The Outsiders Betty Polly

Polly asks Betty to be her baby's godmother.

In an effort to help Polly, Veronica suggested to Betty the next morning that they throw her a baby shower so that Polly would feel loved and supported. Betty thought it was an amazing idea and set about organizing it with the Lodges and Jughead's help. They informed Polly of the plan who, while initially unsure, insisted that both Alice and the Blossoms be invited. Betty did her best to convince her mother to attend and to try and mend the rift between her and Polly. If she decided not to attend, however, Betty assured Polly that it would be her loss. Polly then happily surprised her sister as she decided she wanted Betty to be the baby's godmother; Betty was the only person Polly trusted to care for the baby should anything ever happen to her.

At Polly's baby shower, Betty did her best to make sure everything was perfect for her sister, restraining their mother, who they were happy to see had decided to attend, whenever necessary around the Blossoms, who their mother despised. As the event progressed, however, Alice could not help herself and got into an argument with Penelope Blossom which caused Polly to walk off in tears, much to Betty's dismay. Betty told her mother she had to talk to Polly, make things right, and Alice tried to do so, apologizing to Polly. Alice and Betty then tried to convince Polly to return home, but Polly was worried about how their father would react. Betty stated that their dad would just have to accept the fact that Polly and the baby would be returning home. Polly then revealed that Hal had made an appointment for Polly to have an abortion before she had been sent away, which shocked both Betty and Alice.

Season 1 Episode 8 The Outsiders Polly and Betty

Betty tells Polly she can return home.

The next day, Betty assured Polly that their mother had had no idea that their father had made the doctor's appointment and that she had kicked him out of their house after confronting him. Alice wanted Polly and her baby to feel safe, which meant Polly could return home. However, the next morning, despite Betty's best effort to persuade her sister, Polly chose to live with the Blossoms up at Thornhill.[3]


Season 2

Leaving for the Farm

Hal, Alice, and Betty learning that Polly is leaving

At the Cooper house, Polly revealed first to Betty, then to their parents that she was leaving Riverdale to live at the Farm. She had already called to make sure they still had room for her. What Farm, their mother asked. Polly replied that it was the very same farm that she and Jason were going to run off to before he was killed. Before any rash decisions were made, Hal suggested that they all sit down and talk about Polly's sudden urge to leave. Polly explained that her need to evacuate stemmed from the Black Hood, who was targeting sinners. Betty did not believe that Polly is a sinner, but Polly countered that she was a mother that was carrying her cousin's babies, and decided that leaving Riverdale was the best way to avoid being targeted. Alice strongly objected to this, saying that Polly would leave Riverdale "Over my dead body" Polly replied "It might be over your dead body, but it certainly won't be over mine or my babies" She then left the room, and Hal followed her to try and talk her down.

Polly and Betty saying goodbye

The following night, with her bags packed and a cab just outside the house, Polly said goodbye to Betty. Apparently, Betty was the only member of the family she was extending this courtesy to as neither of their parents knew that she was leaving. Betty questioned if this was truly how Polly wanted to leave things with their parents, leaving for the Farm without saying goodbye. Betty insisted that their mother was sorry. She's always sorry, Polly explained. Right up until she does the next thing that sets everyone off. She insisted that she would be fine, before hugging her and promising to call once she is settled.[4]

Polly briefly appeared in Betty's anxiety induced nightmare. She entered Betty's bedroom to wake her up from her sleep and tell her that Santa Claus was down stairs. Polly then joined their parents by the fireplace as Betty came down the steps. Moments later, Polly was dead, as were her mother and father. They had been murdered by the Black Hood who had disguised himself as Santa.[5]

Polly and Betty arguing

Betty came home from school to find that Polly had returned. Though she was only back to gather her belongings. Much to Betty's surprise, Polly had given birth to the twins. The brief moment of excitement turned into disappointment as Betty realized that their mother would be crushed upon learning that Polly gave birth without telling them. At the very least, Betty wanted to alert their mother of Polly's return, but Polly warned her against such action. The leaders of the Farm, which Betty viewed as a cult, thought it best if Polly severed all ties to their family. Polly insisted that the Farm wasn't a cult. Furthermore, on the Farm, the twins, who were healthy and who Polly named Juniper and Dagwood, weren't subjected to any stigma. While their parents may have hurt Polly, Betty urged her to reconsider her decision to leave as her actions could be perceived as cruel, selfish and vindictive. Polly apologized as she prepared to exit the room with a box of her belongings. As she was nearing the doorway, Betty grabbed the nightlight sitting at the top of the box, claiming that it was hers, and that Polly would probably have no use for it anyways since the Farm likely doesn't have electricity.[6]

Betty came home to find that Polly had returned with her twin babies,Juniper and Dagwood. Betty and Polly shared a hug, during which time Polly expressed her surprise when meeting Chic. Still cautious of Chic given his recent behavior, Betty grabbed Dagwood from him though she made sure not to raise any suspicion. Polly then asked about their father, as she was wondering if they would be attending Clifford Blossom's will reading together.

Polly, Betty and Hal at the will reading

Later that day, Betty attended Clifford's will-reading with Polly and their father. Also in attendance was Cheryl, Toni, Penelope and Nana Rose. In the will, Clifford stated that ownership of Thistlehouse will remain with Nana Rose. To Penelope, Clifford left Thornhill, though that had since burned down. Any and all remaining assets of Clifford's fortune was to be divided in half. The first half would be distributed equally to anyone in Riverdale who could prove that they were of Blossom blood. Alice then arrived at the will reading to confront Hal. She had realized that he only wanted a divorce so that he could cheat her out of Clifford's will. After her mother was escorted from the premises, the will reading continued. The second half of Clifford's assets were to go to his true heirs, Cheryl and the now deceased Jason. As Cheryl gave a speech, Clifford's twin brother, Claudius interrupted the will reading.

Chic refusing to get his blood tested

That night, Betty, Polly and Chic discussed with their mother getting the blood test done so that they could inherit the fortune they were promised through Clifford's will. Oddly enough, Chic refused to get his blood tested, claiming that he didn't know any of the Blossoms well enough to trust them, along with being triggered by needles and not wanting their blood money.

Betty and Polly talking about Chic

After sending Chic's DNA off to be tested at the Blossoms' lab, Betty went shopping with Polly with the money they inherited from Clifford Blossom's will. On their way home, Polly told Betty that Chic was creepy. Betty agreed. It was part of the reason why she submitted a sample of his blood to the Blossoms' lab. Betty began to think that their father was right about Chic being dangerous. She also began to theorize that maybe Chic wasn't even their brother. And if he's not, she would be relieved despite their mother's heartbreak. Betty and Polly returned home to find that Chic had taken Juniper and Dagwood for a walk along Sweetwater River. Just as Betty and Polly began to panic, Chic walked through the front door with the twins unharmed.[7]

Quotes

At the home, the sisters said each of us had a guardian angel. And you're mine, Betty.
— Polly to Betty as they wait at Pop's for the Blossoms.[src]

Polly: "Betty, I've decided... I want you to be the baby's Godmother."
Betty: "Really? Me?"
Polly: "If anything would ever happen to me, the only person I'd trust to care of my baby is you."
―Polly asks Betty to be her child's Godmother[src]

Betty: "Oh, my God! What happened to the twins?"
Polly: "I had them, Betty."
Betty: "You did? You didn't call us? Mom'll be crushed that she wasn't there. We have to call her."
Polly: "No, Betty, we don't. The leaders of the Farm think that it's best if I sever all ties."
Betty: "The "leaders of the Farm"... You mean the cult that you joined?"
Polly: "It's not a cult. And at least on the Farm, there's no stigma on my babies. You can tell Mom and Dad if you want."
Betty: "Tell them what? I don't know anything. Are they healthy? Do they have names?"
Polly: "Juniper and Dagwood."
Betty: "Oh, my God. Polly, please, okay? Mom and Dad hurt you, yes. But what you're doing right now is cruel and selfish and vindictive."
Polly: "I'm really sorry, Betty, but I gotta go."
―Polly and Betty argue[src]
