Plot summary
In the early morning, Frank (William H. Macy) sneaks off into the house. Taking revenge against Sean (Dermot Mulroney), he urinates in his boots and steals his credit card. He then uses his card to buy $200 gift cards in order to pay Bruno (Brett Rickaby) to do the hit.
Lip is sent to jail, where he faces charges for assaulting a police officer. He is later bailed out by Youens (Alan Rosenberg), who warns him he is expelled from campus. Youens instructs Lip to go to rehabilitation, as his alcoholism is worsening. Lip agrees, but postpones until the following day to attend the wedding. He goes to the Alibi, where Kevin (Steve Howey) and the patrons are shocked by his expulsion, with Kevin noting he is reminding him of Frank. Frank meets with Bruno at a warehouse, but Bruno claims not to know what he is talking about. Realizing he was scammed, he contacts a colleague to supply him with a gun. When Patsy's closes, Frank breaks a window and enters Sean's office.
Ian (Cameron Monaghan) fails in finding a new job. After talking with Caleb (Jeff Pierre), Ian returns to the firehouse, telling his superior, Rita (Deirdre Lovejoy), that he will not be excluded for his condition and that he only did what was needed to get a job. When a call is heard, the other EMT paramedics refuse to answer without Ian, prompting Rita to reluctantly allow Ian back. Carl (Ethan Cutkosky) tries to hang out more with Luther (Peter Macon), but Luther makes it clear he will never like him nor support his relationship with Dominique (Jaylen Barron). Debbie (Emma Kenney) almost misses the wedding due to having to take care of Franny, but ends up showing up at the church on time, delighting Fiona (Emmy Rossum).
Before the wedding begins, Frank unexpectedly arrives, intending to walk Fiona down the aisle. When the family opposes, Frank goes on a tirade, scolding his kids for never supporting him. He then reveals that he sneaked into Sean's office, and discovered a secret box with heroin that Sean has been using, devastating Fiona as she was not aware. The family is aghast by Frank's actions; Will (Reed Emmons) runs away from the wedding ashamed, and Lip punches Frank in the face. Outside the church, Sean confirms he fell back into addiction and that he has been using it almost daily for the past few months.
He then leaves Fiona, hoping to save his situation with Will. Lip has a conversation with Debbie, who advises him that she does not want him to end up like Frank. Finally realizing the extent of his actions, Lip has Youens drive him to the rehabilitation center. The rest of the family kidnap Frank and drop him down a freezing river.
