The husband and wife relationship between Hiram and Hermione Lodge is quite complicated due to the former's arrest and imprisonment. Due to Hiram's business deals that he made, he was arrested for fraud and embezzlement. As a result after his arrest Hermione was forced to leave New York with their daughter Veronica and move back to Riverdale.
Hiram can be very persistent when it comes to getting what he want. When he needed his wife to testify for his court trail he even went so far as black mailing her into doing his bidding. Since his arrival back in Riverdale, it appears that Hiram and Hermione are on the same page lately when it comes to business. As it seems that they both have some sort of plan laid out for the Southside of town, needing the people of Riverdale to make a decision at Town Hall on the faith of the Southside, before they carry out their plans. To do this, they require some sort of conflict to be created.
Hiram and Hermione married each other and moved to New York City, where they had a child, daughter Veronica. However, shortly before the start of the series, Hiram was arrested and charged with multiple counts of embezzlement and fraud and subsequently incarcerated. While awaiting his trial, Hermione moved herself and her daughter back to her hometown of Riverdale.
Shortly after Hermione arrived in Riverdale, Hiram had a duffel bag filled with a large sum of money sent to The Pembrooke. The money was to be used by Hermione to pay off the Mayor, Sierra McCoy, as well as the Southside Serpents, who Hiram had hired to decrease the value of the land the Twilight Drive-In was built on. This was so Lodge Industries could purchase the land, a prime piece of Riverdale real estate, at a cheaper price. Hiram was a business man. He saw an opportunity, and he took it. Old Riverdale was dying out, he and Hermione were just helping it along. The only way the Lodges could regain their wealth, was through business opportunities such as the drive-in.
After witnessing her mother kissing Fred Andrews, Veronica asked if she'd be getting a divorce from Hiram. Hermione, while sorry that Veronica was witness to the kiss, had no idea what would happen once Hiram returned. Her relationship with Hiram was complicated.
To award Andrews Construction the contract for the new development of the drive-in's land, Hermione needed Veronica's signature, as she had been designated a legal officer of Lodge Industries when Hiram had been arrested. Hiram had already hired a less than legit crew to helm the development, and Hermione needed two out of three signatories to change that. However, Veronica refused, so Hermione forged her signature, angering Veronica when she found out.
After forging Veronica's signature, Veronica refused to play nice with her mother and began acting out. To make things right with her daughter, the two negotiated terms. Hermione told Veronica that Hiram had made some decisions which distanced him from Hermione, and that she now had to make her own decisions and move forward with her life. She asked Veronica to accept her affair with Fred Andrews until they got more information. In return, Veronica demanded she tells Hiram about forging her signature, which Hermione agreed to. As promised, with Veronica at her side, Hermione called Hiram in prison and told him the truth about the contract with Andrews Construction, and how she forged her daughter's signature.
According to FP Jones, after discovering that his wife was having an affair with Fred Andrews, having been tipped off by an unknown someone, Hiram hired several guys from Montréal where he was incarcerated, to come down and trash Andrews Construction.
Hiram returned to Riverdale following his release from prison. He sat at the table with Hermione at his side, awaiting Veronica's return home. Veronica entered the door soon thereafter. He announced that he had come home early to surprise her, but imagine his surprise when she wasn't there to greet him. Hermione chimed in, telling Hiram about how Veronica drank his Cristal. So disrespectful, Hiram remarked. Not like Veronica at all, to which she admitted to changing since the last time they saw one another. The only question left was whether or not Hiram had changed, which he may have, but not so much that he still didn't want a kiss from his daughter. Veronica approached to kiss him on the cheek before informing him that Fred Andrews would make a full recovery from his gun shot wound.
Secretly Buying Pop's
Hermione and Hiram's quiet dinner was interrupted by Veronica, who came into the room accusing her father of buying Pop's Chock'lit Shoppe the same way he bought the Twilight Drive-In, anonymously. Hiram denied that accusation and insisted that Veronica should sit down so that they could talk civilly. Veronica decided to talk about Fred and the shooting at the diner. Veronica recalled that Fred was shot the day after he rejected Hermione's offer to sell his portion of the SoDale project, leaving Veronica to wonder if Hiram was responsible for the shooting. Fed up with Veronica's accusations, both towards her as well as Hiram, Hermione insisted that Veronica stop. An unconvinced Veronica told Hiram that she was his fiercest protector, which Hermione could vouch for. Whenever someone called him the devil, she always came to his defense. However, she saw him in a new light after he sent Veronica a letter, which unbeknownst to Hermione, was a threat from Hiram to expose her should Veronica fail to cooperate. Veronica then gave Hermione the letter, telling her to think about the kind of man that they are letting back into their lives. After reading the letter, Hermione told Veronica that she wrote the letter threatening herself in order to get Veronica to testify on Hiram's behalf, so that they could be reunited as a family once more, or so she claimed. Hearing this, Veronica pointed out to the both of them that they were made for each other.
The following night, Hermione and Hiram attended Retro Night at Pop's in support of Veronica and her cause to keep the shoppe from closing. With the night being a new beginning for Pop's, Veronica suggested that maybe the night can be a new beginning for them as well. However, she asked for total transparency in return. In the spirit of that, Hiram proposed that Lodge Industries make a "charitable contribution" to the diner.
After a show of appreciation from Pop Tate, in which he thanked the Lodges for their generous contribution, Hermione told Hiram that she didn't know they were in the charity business. Hiram, however, revealed that, as of five minutes ago, he had secretly bought the diner from Pop. In exchange for his silence, Hiram told Pop that he could stay on as manager. It was nice to have Hiram back, Hermione stated. He then thanked her for having lied to Veronica about writing that letter that he really did write, knowing that Veronica never would've forgiven him had she learned that he threatened her. Hiram complimented Hermione on her loyalty, which he has concluded "knows no bounds".
Hermione, Hiram, and Veronica returned to the Pembrooke after Retro Night, where they were greeted at the door by their new doorman, Andre, who had replaced Smithers due to his mother falling ill overseas.
Hiram joined Hermione and Veronica in the main room after hearing the two of them arguing just outside his study. Veronica asked if her inner-circle of friends could come over to watch the season premiere of The Matchlerette. He was even extended an invitation to join them as Veronica's friends were supposedly dying to meet him.
Before leaving out for dinner at the club that night, Hermione and Hiram passed through the living room to greet Veronica's friends. She introduced Hiram to each of her friends, starting with Betty, then Jughead, and lastly Archie, the boy who had captured his daughter's heart. He and Archie shared a firm handshake as he instructed Archie to call him Hiram rather than Mr. Lodge. Hiram and Hermione couldn't help but overhear their discussion in regards to their frustration with Sheriff Keller and his inability to catch the killer. As someone who had his fair share of run-ins with the law, Hiram could say with confidence that the police weren't always the solution. Drastic times called for drastic measures, meaning they would have to take justice into their own hands. Hermione then reminded Hiram that they had to leave. Before leaving, he invited Archie over for dinner later in the week. He looked forward to seeing what Archie came up with for saving Riverdale.
While getting prepared for another evening out with Hiram, Hermione was standing in front of a glass mirror where she was putting on her pearl earrings. She spotted Hiram after he was finished getting ready, asking him if he could zip her dress up for her, which he was more then happy to oblige her request. While he was zipping her up, he informed Hermione that he overheard her conversation that she had earlier with Veronica, where they were in the dining room. He told Hermione that within their apartment, sound carried, even in his study with the door closed, he could hear her and Veronica in the dining room, as if they were all together in the same room. He continued to inform her that if she wanted to burn down her relationship with their daughter, it's her business, however, warning Hermione to never, ever try to poison Veronica against him. Asking her if she heard him clearly, Hermione agreed. Before leaving the room, he complimented her that she looked nice.
As planned, Archie came over for dinner, during which time he complimented Hermione on her well-prepared meal. They briefly discussed how Archie saved Ethel Muggs the prior night. Unfortunately, the individual stalking her got away. Admittedly, they needed to increase their response time. Hiram understood Archie's need to be ahead of the threat. After Hermione and Hiram exchanged looks from across the table, which went unnoticed by Archie and Veronica, Hiram asked Archie if he's ever had rum, then inviting him into the study to have a drink from the signature Lodge family label. Veronica mistook this as an invitation to join them, however, Hiram asked that she stay behind, providing him and Archie with the opportunity to talk man-to-man. 
With the Black Hood's presence growing in Riverdale, Archie took it upon himself to send a message to the killer. Now, with the Red Circle's public message to the Black Hood sending the town in an uproar, Hermione and Hiram confronted Veronica on her potential involvement with the Circle's video. While Veronica wasn't involved in the making of the Red Circle or the video, she didn't seem to think it was as serious as they were making it out to be. Hermione explained that it was a video threatening violence, which in turn made Archie dangerous in the eyes of her and Hiram. Hermione took her stance on the matter a step further by forbidding Veronica from seeing Archie any further. However, Veronica had no intentions of breaking off her relationship with Archie without first getting his side of the story. Once Veronica was out the room, a grin formed on Hiram's face, leaving Hermione to wonder what he was smiling about. Hiram explained that between the Black hood, the Red Circle, and the Town Hall meeting, there was so much chaos and confusion taking place in Riverdale
Later on in the week, Hermione and Hiram attended the Town Hall meeting, where Mayor McCoy welcomed all to the event in hopes that she could address their concerns and if possible, ease their minds, as she too shared their desire to protect their town and their children. While the meeting started out peaceful and civilized, it quickly escalated, turning into a shouting match between two divided sides, with one side being led by Alice, who believed the Southside was responsible for everything wrong with Riverdale, and the other side being led by Fred, who believed that this was a time where they needed to unite rather than fraction off because only then would they truly be defeated. Hermione had told Hiram that Fred was going to be a problem, though Hiram wasn't quite sure of this being true. The town loved and trusted Fred. It could work in their favor. Moments later, Betty and Jughead entered through the back doors to alert everyone that the Black Hood was on his way to the Town Hall, where the cipher claimed he would strike next. Hermione and Hiram presumably evacuated the building with everyone else.
SoDale Open House
In Hiram's study, Hermione read aloud to both him and Veronica, the latest published article from the Register, which addressed the rise in crime in Riverdale, more specifically the stabbing of Northside teen, Dilton Doiley. The recent incident confirmed that the real threat wasn't the Black Hood, rather the Southside and its corruptive forces. The article, which was written by Alice, accused Hiram of wanting to profit off of Riverdale's misfortunes, instead of fixing them. To make matters worse, all this was occurring just before their open house. Hiram told Hermione that they couldn't allow anything to derail the SoDale project, that included Alice, the southside gangs (Southside Serpents and Ghoulies), and the Black Hood. Their biggest problem at the moment, was capital. They were running out of it at a fast rate, Hermione explained. Fortunately, Hiram had invited potential investors to the open house, the St. Clair's, to be exact. They were coming up from New York. Veronica was delighted to hear that her old friend, Nick St. Clair, would be coming up with them for the opening. If they could get the St. Clair's to invest, then others would surely follow. Hermione recalled Veronica wanting a seat at the table, and with Nick having his father's ear, she hoped that Veronica could help them close the deal by showing Nick all that Riverdale had to offer.
A few days later, Hermione and Hiram arrived at the opening, arm-in-arm, greeting guests as they proceeded down the aisle. If the successful turn out of the open house didn't convince the St. Clair's to invest, nothing would. Hiram then called over Veronica to ask how things were going with her showing Nick the best that Riverdale had to offer. From all reports, Veronica's charm offensive was paying off.
Hermione, Hiram, and Fred then got on stage to make an announcement as the hosts of the event. Hiram announced that A new story began in Riverdale that night. A story about reinvention and aspiration. The building would be the first chapter of that story. Luxury apartments, shopping, and even a golf course. The Southside as they knew it would be gone, replaced with a new Eden. So, they raised their glasses to a brighter tomorrow. But for that day, they would celebrate with a little music from Josie and the Pussycats.
Hermione and Hiram set up a meeting with Penelope Blossom following the incident at their open house, where Nick St. Clair attempted to rape Cheryl. Even though Penelope appreciated them calling her after Cheryl had told them, she wished that they would've stopped her from talking to the Sheriff. Penelope was skeptical of Cheryl's act of damsel in distress and wasn't convinced that Cheryl was completely innocent. She concluded that Cheryl had to have provoked him somehow. However, Hermione stated that per Veronica's account of the incident, Cheryl did nothing wrong. Penelope then told them that she wanted the situation to be handled discreetly. Exchanging looks with Hermione, Hiram agreed, also sure the St. Clairs felt the same way. Ending the meeting, Penelope said she'd handle the Sheriff and inform him that they wouldn't be pressing charges, because after all, nothing really happened to Cheryl.
Later that morning, Hermione and Hiram attended the meeting at the Cooper house that Alice had arranged in order to deal with the use of Jingle Jangle at Nick St. Clair's party. All the parents along with their children attended. Alice was quick to judge the party as a "bacchanal". Hiram immediately replied to her harsh remarks, referring to her as "Acid Queen Alice" and telling her to careful at throwing stones as they all recalled her mugshot that Betty recently printed on the newspaper's front page. When Hermione demanded to know who brought the Jingle Jangle to the party, Reggie Mantle confessed that he brought the drugs that he acquired from a dealer on the Southside, who he suspected of being a Southside serpent and a student at Southside High. While they admittedly shouldn't have taken the Jingle Jangle, Veronica pointed out that Nick asked for it, and later pressured them into taking it. Furthermore, he attacked Cheryl. If anyone should be under interrogation, they believed it to be him. However, as Sheriff Keller explained, prosecuting Nick would be difficult given that they were all unreliable witnesses due to the fact that they were high. When Veronica retorted that when Josie and herself witnessed the incident with Nick and Cheryl, they weren't on drugs, Sheriff explained that Jingle Jangle stayed in one's system for up to three days. Unfortunately, it had only been one day since the open house, so this would raise a credibility issue in court. Josie's mother was appalled to learn that she too had participated in taking Jingle Jangle despite knowing how her father struggled with addiction. This triggered Mayor McCoy to take harsh measures against the Southside.
Hermione and Hiram were playing chess in the living room, when Veronica entered, confronting her parents after learning from Cheryl that they were still doing business with the St. Clairs and letting them invest in the SoDale project. Hiram tried to explain that Cheryl's accusations were not strong enough as she didn't have any physical evidence to support her claim, though this was not enough for Veronica. In an attempt to corroborate Cheryl's claim, Veronica decided to confess that Nick tried to do the same to her. Upon hearing this, her parents' attitude toward the situation drastically changed from dismissive to a protective, which resulted in them vowing to not take a single penny from the St. Clairs ever again.
Later, as Hermione, Hiram and Veronica sat in the living room, they received a call. Hermione picked up the phone, getting news from Andre that the St. Clair's got into a car accident; Nick would gradually recover, with time, but Xander and Simone St. Clair's status was currently unknown. "Oh, well. Karma's a bitch", Veronica said, as Hermione and Hiram continued playing chess.
A Letter from the Black Hood
After receiving a threatening letter from someone claiming to be the Black Hood, Hermione and Hiram called Sheriff Keller over to investigate. As the Sheriff was leaving, Veronica returned home. They informed her of the letter, and how it threatened that they would be targeted and punished for their sinful ways. Veronica was terrified by the letter considering that they were actually sinners, though Hiram and Hermione didn't express much concern given that dozens of households received the exact same letter. Not to mention that the Pembrooke was a fortress and Andre was trained in martial arts. In regards to Veronica's every day activities, such as going to school and shopping, Andre would drive her, and when he wasn't available, they'd hire a car service. After talking it over, Hermione and Hiram also decided that they wouldn't mind seeing more of Archie considering that he was brawny and devoted to Veronica.
The next day, while at the breakfast table, Veronica told Hermione and Hiram that Archie had said that he loved her, though she didn't say it back as she felt it was too soon. It didn't matter what Archie said or didn't say, it was about whether or not Veronica was ready to here it, Hermione and Hiram stated.
The Family Business
In the days leading up to Christmas, the Lodges ate dinner as a family, during which time Hermione asked Hiram about the Spiffany's bag she saw him come in with earlier that day. It looked about the right size for a Glamerge egg, she added. That depends on whether she's been naughty or nice this year, Hiram replied. Hiram then assured Veronica that he had her Christmas list as well. But he asked of her to refrain from snooping as she does every year. However, Veronica wasn't in the Christmas spirit. She was frustrated and she wanted Hermione and Hiram to take a look at themselves and realize how fortunate and wasteful they were, spending money on bejeweled eggs like they were a family of Russian oligarchs while there were people in Riverdale who couldn't even afford to pay their own bills, such as Fred Andrews, who Veronica learned from Archie was drowning in medical bills to the tune of $86,000. Which is why she was hoping that Hermione and Hiram would cover his expenses. Unfortunately, the Lodge Charitable Trust had made its donations for the fiscal year. Fred would have to tighten his belt, so to speak. However, as Veronica informed Hiram, Fred was already selling Christmas trees for extra money. That's the kind of father he was, Veronica surmised. Regardless, Hiram wished to hear no more on the matter, storming off to his study.
The following night, Hermione and Hiram returned to the Pembrooke from last minute Christmas shopping after receiving a call from the bank, confirming a charge that was made from Hermione's credit card, in the amount of $86,000. They realized that it was Veronica's doing and came home to confront her. She deiced that Hermione and Hiram would cover Fred's medical expenses considering that they had the money to buy Pop's and then lie to her face about it. Veronica asked how it was that they could afford an entire diner. Hiram addressed the fact that she wanted a more active role in Lodge Industries, which they gave to her. In response, she broke into his office and tried to use whatever she could find as leverage against them. While Hiram admitted that it was a lot Veronica didn't know, he explained to her that this was on purpose. Veronica questioned how she could be apart of the family if they continued to hide things from her. With her name being on all of the documents in Hiram's desk, Veronica insisted that she had the right to know the truth about everything. Hermione agreed that she had the right to know the truth. However, this would also mean that the time for being "Daddy's little girl" is over. It was time for all of them to work in lockstep. Hiram agreed, telling Veronica to follow him to the study.
In the study, Hermione and Hiram revealed everything to Veronica about their family's business. Veronica agreed to join them in running Lodge Industries, though she had one condition; she refused to do anything illegal. Which was fine considering that they were involved in any illegal activity either. When Veronica gave her a look, almost as if to say that she wasn't fooling anyone, Hermione shared with her two words to live by; plausible deniability. In regards to the charge that Veronica made towards Fred's medical bills, she wanted that to stick. While Hiram was initially against doing so as it would only further complicate matters, Hermione agreed to Veronica's demand, stating that they could smooth it over. Furthermore, they needed Fred for what would come next. Assuming that the Fred situation could be finessed, Veronica agreed to the deal with her parents.
On Christmas morning, the Lodges unwrapped their gifts, during which time, they informed Veronica that Archie had stopped by the day before to leave her a gift.
Afterward, they took a moment to check in on Veronica to ensure that she was still on board with their "plan". Veronica assured them that she was. Veronica assured them that she was still on board. Hermione pressed her further revealing the severity of what's to come. She explained that once completed, she would be at ground zero, i.e. the eye of the potential hurricane. Their concern went unwarranted; she believed, regardless of what's to come, she'll be fine. However, she assured her parents that she'll be able to keep her classmates from revolting once the news broke. With renewed faith, they nodded at their daughter in silence.
At the Mayor's office, Hermione and Hiram discussed the closure of Southside High. Sierra explained that with news of Southsiders headed to Riverdale High School, her phone was about to start exploding with calls from outraged parents. Hermione attempted to calm Mayor McCoy's concerns, telling her that it would only be news for a couple of days then it would blow over. She referred her to how quick Riverdale had stopped talking about the Black Hood since he'd been stopped. Hiram reassured her and claimed after a couple of weeks, the Lodges would quietly go about purchasing the land beneath Southside High. With Mayor McCoy's assistance in closing down the school, Hermione affirmed that she'd get her commission, a sizable donation to her re-election campaign. With their business meeting coming to a close, Sierra's phone began to light up with phone calls.
Hermione and Hiram invited Archie over for dinner that night where he thanked them for paying his father's medical bills. They were happy to assist. Veronica explained that, in return, she had hoped Archie would stand beside her in welcoming the incoming Southside transfers. Archie agreed and took the opportunity to ask him and Hermione about the closure of Southside High. He assumed, that being close to the SoDale project, it's bad for business. Hiram corrected him, explaining that drugs, gangs, and violence was in fact bad for business. Archie assumed that investors, like the St. Clairs, must be fine with it as well. Veronica updated him on the fact that they were no longer investors. Hermione confirmed that due to what had transpired between Nick and Cheryl, they had severed all ties with the family. They didn't even call them after the accident. This news gained Archie's attention and so he asked what happened. Hiram claimed not to know what truly happened, that he either had a car accident driving back to Vail or on the slopes. Archie asked if he was alright. Hermione assured Archie that he'd recovered enough to be back at Greenwich Prep.
Hermione and Hiram checked in with Veronica after a tumultuous week of turmoil between Southside and Northside integration. They'd learned some news from Mr. Weatherbee, relayed to them from Mayor McCoy, which was that the integration of Southside High was not going well. Veronica mused that Reggie was just being Reggie, however she elaborated that gang ware, specifically the Serpent Jacket, had become a flashpoint. She proposed that a charitable donation would help them, that looking the part would quell the ever rising tension. Considering their options, Hiram looked towards his wife; they accepted her proposal in silence.
At the Andrews house, Hermione, Hiram and Veronica attended a meeting with Fred, Mayor McCoy and Sheriff Keller to discuss the students who had been transferred to Riverdale High one week before and how their parents were in Mayor McCoy's office everyday to demand that she reopen Southside High. Which is why Hermione, Hiram and Fred had discussed how their new neighborhood could use something positive to focus on. With Mayor McCoy's blessing, they'd like to make Pickens Day a celebratory event. Sponsored by Lodge Industries with Andrews Construction co-sponsoring. Mayor McCoy concluded that they wanted to make Pickens Day a commercial event for the SoDale, similar to their open house. But Veronica interject to provide some clarity. She pointed out that the open house was for investors while Pickens Day would be for North and Southsiders alike. Two halves of a whole coming together. Mayor McCoy worried that trying to distract people with a party would backfire, resulting in violence. While the Southside Serpents had been laying low, they were wild cards and reasons for concern. Having prepared for just that scenario, Hermione, Hiram and Fred had offered to hire the Serpents as security for the event since FP had told Fred that the Serpents were looking for work. Furthermore, the party would let the Southside know that they hadn't been abandoned. The meeting was then brought to an abrupt as Archie returned home.
Hermione and Hiram watched from the crowd as Veronica and the Pussycats performed on stage. Unfortunately, their performance was interrupted as the Serpents marched into the park as a protest with duct-tape covering their mouths and signs that read 'honor this land' and 'sacred land'. With Sweet Pea and Fogarty at her side, Toni, who seemingly led the protest, stood in front of the stage to announce that they represented the dead and the silenced. Pickens Day was a lie. General Pickens slaughtered the Uktena tribe, Toni's grandfather's family. And the land in which they were standing on, would soon give way to a new Southside, which was stolen from them. While the Serpents couldn't bring them back, they could at the very least honor them. Hoping to defuse the protest and resolve any conflict, Hiram got on stage to applaud the Serpents for standing up for justice, as well as the honor and legacy of the Uktena, who contribute to the rich tapestry that is Riverdale, that is the Southside and that will be SoDale.
The following morning, Hermione, Hiram, Mayor McCoy and Sheriff Keller gathered at Pickens Park after being alerted of the desecration of the General Pickens' statue. Its head had been removed and red paint covered the statue to simulate blood. Since Hiram and Hermione were calling the shots, Sierra asked how they would like it to be handled. Hiram replied that the investigation of the missing head should be handled swiftly and with extreme prejudice given that the most likely suspects were the Serpents.
Picking up from where the previous episode left off, Hermione, Hiram and Veronica gathered around the head of General Pickens' statue as it sat on the table. Hiram interpreted the delivery of the head as a deceleration of war. Hermione stated that they always knew that they would have to go to war eventually. But of course, there was another option. Veronica reminded them that at Spence, she was Secretary General of the Model UN, and before declaring war, they'd always try to negotiate a settlement. So if she could broker a detente between the Contras and the Sandinistas, then Hiram could surely de-escalate relations with the Southside Serpents. Veronica offered to get them to the table while all he had to do is play nice, which shouldn't be too much to ask for from an accomplished businessman such as himself.
A couple days later, Hermione and Hiram got into a heated argument with Mayor McCoy over the Southside land development. As she exited the study, Sierra told them that she was fairly close to telling Jughead everything and that it would be a lot worse for them than it would be for her. With Veronica standing just outside the door, Hermione and Hiram explained to her that given exposé that Jughead was writing about them, they decided to accelerate the timetable. So they told Sierra they might have to announce their plans for Southside High earlier than expected, but she refused and demanded that they wait until after her reelection. Should they proceed without her, she threatened to expose them. If this wasn't handled properly, the whole town would be out for their blood. However, if they got Sierra out of the Mayor's office, under a cloud of scandal, the damage she could do to them would be minimized. They would go about doing that by revealing her affair with Sheriff Keller.
The following day, much to Hermione and Hiram's surprise, Sierra resigned from office over a live broadcast. She claimed that seeing them through a triumphant Jubilee and the terrors of the Black Hood killings had taken a personal toll. So she had decided to step down as Mayor, to spend more time with her family and to return to her own legal career right in Riverdale. Hermione and Hiram were surprised by Sierra's sudden decision to resign since they hadn't even made their play yet.
Hermione: "I didn't know we were in the charity business."
Hiram: "Oh, we're not. As of five minutes ago we, uh, own this diner. In exchange for silence, I told Tate he could stay on as manager."
Hermione: "Nice to have you back, Hiram."
Hiram: "Hermione, thank you for saying you wrote that letter. Veronica never would have forgiven me for that. Once again, your loyalty knows no bounds."
