6. The Defenestration of Frank

Fiona (Emmy Rossum) buys an A/C unit for her bedroom, and decides to pursue buying the laundromat from Etta (June Squibb). Fiona convinces her in buying the lease by asking for a $100,000 loan, and Etta will still be allowed to live in her apartment upstairs. However, Fiona is disappointed when the bank is only willing to lend $80,000.

Debbie (Emma Kenney) has moved in with Sierra's paralytic brother Neil (Zack Pearlman), whose brain injury has caused him to say the very first thing that comes up in his head. She invites her family to dine with them, except for Fiona. Carl (Ethan Cutkosky) has been accepted into military school, but is having second thoughts about joining after considering he might be a victim of hazing. Dominique (Jaylen Barron) also is interested in getting back with him, although Luther (Peter Macon) later shows Carl that she is once again cheating on him. While transporting a woman in the ambulance, Ian (Cameron Monaghan) is shaken when the woman dies despite his efforts.

As Frank (William H. Macy) gets the inhabitants at the shelter to act as beggars in the street, he has the church donate some furniture. Subsequently, he resells the furniture and keeps most of the money for himself. As he is counting the money, he is visited by Debbie, who asks for a favor; she wants to marry Neil and wants him to sign papers in allowing it as she is not an adult. Frank refuses, feeling that Debbie is condemned to a long life before finally getting Neil's cash as he is still relatively young. Debbie angrily leaves, although one of Frank's inhabitants overhears Frank explaining his money plans. Later, Frank returns to the shelter to bury the money, only to find that they have already discovered it. Angry at Frank's actions, they kick him out of the window and exile him from the house.

Lip (Jeremy Allen White) continues having sex with Sierra (Ruby Modine). However, she feels insulted when he is unsure over the status of their relationship. Sierra makes it clear that while she likes having sex with him, she is not interested in pursuing something big with him, and Lip agrees in keeping it the way it was. Lip also continues his operation with Joaquin (José Julián) at the company, until the DEA arrives to shut it down. When Fiona tells him about the loan, Lip is infuriated when he learns that she placed the house as a collateral until she pays the rest of the $20,000 loan.

Kevin (Steve Howey) is disturbed when he discovers Yvon (Pasha Lychnikoff) having sex with a woman, believing it to be Svetlana (Isidora Goreshter). He and Veronica (Shanola Hampton) check again, and are horrified that it was actually Svetlana. When they confront Svetlana, she confirms the sexual relationship but also drops another surprise: Yvon is not her father, is her husband.

Ian and Trevor (Elliot Fletcher) want to pursue a sexual relationship, but discover that both of them are " tops ", and they end up questioning how to proceed. Debbie asks Fiona to sign the papers, and is surprised when she actually agrees. That night, after being encouraged by his siblings, Carl finally leaves for military school. As they leave the bus station, Lip tells Fiona she can still reconsider the loan. Fiona simply stays silent, and Lip angrily leaves. At military school, a group of bullies tries to intimidate Carl. Carl easily beats the leader, and the rest of the group chooses to leave him alone.
