Summer Time
performed by DJ Ax

Cathy learns from Dr. Todd just how little time she has left, and for the first time in her life, starts to appreciate her body. Paul tries to make sense of his wife's request to live apart for the summer by signing up for couple's therapy. Adam, desperate to get away from his "crazy" mom, attempts to sneak off to soccer camp without her knowing.

Summertime tells the story of an American woman spinster from Ohio who falls in love while vacationing in Venice, Italy.

Summertime in Chicago, and the Gallaghers are back and up to the same tricks. Frank - after losing a bet with a fellow bar patron - is now in over his head $10,000, and Karen refuses to let him steal the money from Sheila again; Frank uses Liam to win sympathy panhandling, until the bar patron takes Liam as collateral for the money. Lip wants to continue seeing Karen, who is now attending Sex Addicts Anonymous meetings and in a sex-free relationship with a fellow group member; however, he is also preoccupied with summer courses, running a fighting ring, and selling pot and alcohol out of an ice cream truck with Kevin. Fiona and Veronica are waitressing at a local club; Fiona is seeing someone to get her mind off of Steve, though V says her new boyfriend is "a rebound" and "even looks like Steve." Ian is still working for Kash and Linda, whose marriage is deteriorating despite her pregnancy; Ian also expresses interest in attending West Point, and Lip agrees to help him with his application and grades; he is also looking forward to Mickey's release from jail. Debbie and Carl run a babysitting service in the house to bring in extra funds. Sheila is simultaneously trying to find Eddie (who committed suicide last season) and working on being outside her home.
