Eventually, after Lucy breaks down and begs to see the video itself, Stephen hands her the tape, claiming he hasn’t made copies — though he cryptically warns she can choose whether to believe him. Lucy’s mental state is left ambiguous: the next day she gives the same warning to freshman Tegan that she already gave the day before, suggesting she might be emotionally unstable or that her grasp on recent events isn’t solid.

While Bree wrestles with the chaos caused by her mom and Pippa and Wrigley sleeping together, she retreats to Evan’s place, while Evan is showering she sees a Facebook photo from the Hawaiian party (where Evan cheated on her), and realizes Evan and Lucy were together in the background of that photo.

Lucy shares her own confession that she and Evan slept together at the Hawaiian party the previous year. Pippa, however, reacts angrily saying their situations are not the same and casting Lucy out, no longer wanting a friendship with her while also promising to not tell Bree.

Later, Wrigley is trying to get ahold of Bree but is interrupted by Pippa who confesses to cheating and shares she's gay. Wrigley is instantly forgiving of the cheating, having suspected something was off between them. He also accepts her sexuality and the two decide to remain good friends. Afterwards, Pippa and Wrigley discuss Stephen, with Pippa warning Wrigley that he's a terrible person. She tells him that he was the one who sent Diana's nudes picture to her parents, and that she's not going to Yale because of being afraid of Stephen.

We then see Lucy in class, but just as the lecture begins, she sees her video being played on a classmate's laptop. She bolts out of class and heads to her dorm, but on the way there she can see and hear the video being played by several students. She confronts Stephen and angrily attacks him, but he humorously shares he's not the one who leaked the video. Lucy heads to Alex's, hoping for empathy and comfort. Alex, hurt and angry, hints at his own past of sexual abuse from his foster home. He asks Lucy to leave and their relationship ends. As Alex heads back in side, we find Bree who was sleeping over in his apartment. Bree, despite being angry with Lucy, shows some empathy for her situation. Alex warns she shouldn't have been so trusting of others.

When Bree returns to her dorm the next day, she shares her confusion and disgust over Lucy's actions. Pippa confesses that she was the girl Chris sexually assaulted last semester and Lucy made the accusation so Chris could be punished. Bree and Pippa feel guilty over her harshness towards Lucy. They try to speak to Lucy but learn she's locked herself in her dorm. With the help of her RA, they're able to get inside and help comfort her. This is short-lived, as the dean is requesting to meet with Lucy immediately. Lucy meets with the dean who tells her that she's being expelled, which includes ending her desire to complete her study abroad program the following semester. Lucy, in shock, accepts the news and goes to pack up her items.

Elsewhere, Stephen finds Wrigley at lunch and casually dismisses what's happening to Lucy, saying she should suffer the consequences of her actions. Wrigley is left disgusted by Stephen. Later on, Stephen receives a call from Yale admissions, who rescind his offer. They tell him they learned of inappropriate conduct, including sending inappropriate pictures of a fellow student. Stephen angrily asks who shared the information, but the admissions office says the information is confidential. It's soon hinted that Wrigley was the one who made the call.

Back at Bree and Pippa's dorm, Evan stops by after looking for Bree ever since she abruptly left his apartment a couple days prior. She confronts him, asking about the affair with Lucy which he admits to, and the two decide to keep their relationship going. Wrigley arrives to try and make up with Bree, but finds her with Evan. She subtly reveals she knows about him and Pippa's night together, and that she's going to stay with Evan. Both Evan and Wrigley leave, and Bree sobs her in dorm over everything that has transpired the past few days. She then goes into her drawer and we see that she stole the memory card with Lucy's video on it, indicating that she leaked the video out of revenge. She destroys the card, crushed over her actions.

As Lucy is packing her items to leave Baird, Diana walks in and kindly offers to help. She tells Lucy that life will be hard for awhile, but not to give up as things will get better. Lucy is later seen loading her belongings into her mother's car. She says a heartfelt goodbye to Bree as Stephen watches from a distance.

Flash forward to 2015, Lucy and Bree joyously dance at Bree's wedding reception. Stephen is drinking watching them, annoyed that their friendship has survived. Lydia, annoyed with Stephen's actions, declares that wants to leave. Stephen tells her their relationship was based solely on him making Lucy jealous and that he's still involved with her. Lydia throws her engagement ring back at him and leaves him instantly. On the other side of the dance floor, Wrigley, Pippa, and Diana playfully banter, and we learn Diana ended up at Yale in the end.

As the wedding comes to a close, Stephen, having felt like he's lost, makes a final attempt to ruin the evening. He confronts Bree, confused as to why she continued on with the wedding. We learn the phone call Bree took was in fact Stephen playing Evan's confession tape. Bree says she doesn't care what Stephen says or does, everyone is happy, and he has nothing. Stephen figures out that not only has Bree known the whole time, but pieces together that she must've been so forgiving because she was the one that leaked Lucy's tape. Bree unconvincingly, denies this.

As the DJ announces the end of the night, Stephen steals the mic to reveal everyone's secrets. He tells Evan he's hated him for years, tells Lucy that Bree leaked the tape, shares that he and Lucy slept together that morning, and then exposes Wrigley and Bree's affair. Everyone is left confused and angry, processing the information and discovering the lies people have been holding onto for months, if not years. Chaos erupts, with Bree and Evan each attacking Stephen, Bree trying to explain herself to Lucy, and later Evan confronting Wrigley. Diana and Pippa, the only ones not involved in the confessions, happily leave together, putting the drama behind them.

Stephen tries to convince Lucy to leave with him, telling her that they both have nothing now, and need each other. Bree tries to convince Lucy to stay, but she's upset with Bree over the video leak. Bree walks away from Lucy to keep Evan from fighting with Wrigley. As Evan screams at Wrigley, all Wrigley can do is look over lovingly at Bree who smiles in return. Stephen waits in his car as Lucy eventually comes out, and agrees to leave with him, despite saying she hates him. In the final scene, Stephen and Lucy stop by a gas station where Lucy goes inside to get them coffees. When she comes back out, she sees Stephen has abandoned her there, leaving just her purse behind. However, instead of being sad that he tricked her again, she lets out a laugh, knowing that he's still the same guy from college. Lucy stands there and smiles, relieved to finally be free of him.
