Plot summary
Frank continues taking care of Peggy, rotating from staying at his house and with Sheila. While buying medicine for his mother, Frank goes to the store and catches Ian and Mickey having sex in the freezer. Despite their horror, Frank is not annoyed and leaves with the supplies and some money from the cash register.
Now back with Karen, Lip wants to quit school to focus on becoming a father, but Fiona tells him that if he reconsiders, she'll go back and get her GED. However, Karen surprises Lip by announcing she wants to give her baby up for adoption, feeling she would be an unfit mother. They go to different adoption agencies, but Karen seems more concerned about the money than her baby's future. This leads to an argument, wherein Karen reminds Lip that he is not confirmed to be the baby's father. In an attempt to get closer to Fiona, Steve volunteers to be Carl's football coach, much to Fiona's dismay.
Meanwhile, Mickey decides to kill Frank, as he fears he will expose his homosexuality and face the wrath of his father. Ian tries to comfort him, but Mickey makes it clear they are not a couple. Mickey and his gang ultimately prepare to ambush Frank in the street, but Mickey is unable to go forward with the plan. Instead, he approaches a nearby police officer and punches him, violating his parole and allowing him to get sent back to prison.
Upset by Karen's decision, Lip insults a teacher and breaks a window, getting himself expelled. Fiona is informed about this by Lip's guidance counsellor, but discovers Lip is still being offered a chance to prove himself at another school. When Lip makes it clear he will not go back to school, Fiona gives him an ultimatum to either return to school or leave the house, prompting Lip to move out. Sheila and Jody take care of Peggy as her condition starts to worsen. Sheila and Peggy reconcile in the process, and Peggy reveals her intentions to send money to each of Frank's brothers; however, she refuses to give any to Frank. Wanting to hasten her own death, Peggy convinces Sheila to smother her with a pillow. After being informed of his mother's death, an emotional Frank visits Monica, crying that his mother died.
