Plot summary
Frank (William H. Macy) continues accompanying Bianca (Bojana Novakovic), who buys a $10,000 bottle of whiskey for themselves. Lip (Jeremy Allen White) is still in a sexual relationship with Helene (Sasha Alexander), and grows to enjoy the benefits of the open relationship, as he gets himself invited to an exclusive party.
Ian (Cameron Monaghan) is held in custody, facing charges for going AWOL, damaging equipment and falsifying Lip's ID to enroll, which could lead to a court-martial. Fiona (Emmy Rossum) consults with the military investigator to discuss Ian's bipolar disorder, claiming it is affecting his view, but Ian is still not willing to accept the diagnosis. Debbie (Emma Kenney) and Mickey (Noel Fisher) want to take revenge against Sammi (Emily Bergl), who proclaimed she will move out of the house the following day. Fiona is taken by surprise when Gus (Steve Kazee) returns home after his tour has been cancelled, but she is dismissive of his questions, preferring to stay with Sean (Dermot Mulroney).
Feeling ecstatic, Bianca convinces Frank to try sex on the train tracks. Just as she reaches an orgasm, a train almost hits them, but they move aside just in time. While Bianca is not bothered, Frank is shaken by the experience. Later, Bianca tries crack for the first time and has sex with Frank in the Gallagher household. As Kevin (Steve Howey) tries to fix a broken pipe at the Alibi Room, Veronica (Shanola Hampton) argues with him over only returning because Lip kicked him out. As they apologize over cheating each other, they seize the leak to have sex in the bar, reconciling. At the party, Helene introduces Lip to a friend who works at aerospace, although Lip debates over choosing his new life to his old life.
Ian is visited by Monica (Chloe Webb), who has kept in touch with him. Monica consoles her son, telling him he does not have to change for anyone. Mickey drugs Sammi with rohypnol, but he and Debbie are shocked when Sammi appears to have died. They decide to hide Sammi's body in a storage container; it is later revealed that Sammi is actually alive. Bianca discovers that Frank called her family to help her accept chemotherapy, and she decides to leave for Costa Rica to spend her last days. Frank opens up, explaining that he was afraid of never seeing her again, and she allows him to accompany her. When Fiona and Mickey visit once again the facility, they are informed that Ian has been allowed to be released. However, they are astonished to learn that Ian already left with Monica.
