Ruby Modine

Ready to disown his family, Frank takes Liam under his wing and starts a new life barricaded on the top floor of the Gallagher home. Fiona, meanwhile, adopts a new, relaxed attitude and starts running Patsy's Pies on her own terms. In order to save the restaurant, she cleans house and hires a new staff. Debbie gets into trouble in the stroller business; Ian tries out heterosexuality; and Carl finds himself forced into abstinence when he has to spend 72 hours not thinking about the opposite sex after his circumcision.

Fiona learns that owning a laundromat is costlier than expected. Frank helps Liam get into a plush new school after his old one is permanently shut down. Meanwhile, Debbie cleans up her act for her review and grows closer to Neil (guest star ZACK PEARLMAN). And while Lip gets scared by his newfound closeness with Sierra (guest star RUBY MODINE), Kev and V try to cope with the recent discovery of an upsetting secret Svetlana kept from them.

Kevin, Veronica and Svetlana start a topless maid service. At the shelter, meanwhile, Frank makes new friends to replace his old family - leading them to a for-sale house converted into the Gallagher Home for the Homeless. Plus, Debbie's new lifestyle comes to an abrupt end; Carl gets a syphilis scare; Ian struggles with a breakup; Lip struggles with humility at his new internship; and with Fiona on the run to clean up after her siblings, business at Patsy's hits the skids.

In the season finale, the Gallaghers deal with the loss of one of their own, while grappling with their grief. Meanwhile, Kev and V get their revenge on Svetlana.

Worried that he and his new Gallagher clan are going to lose yet another shelter, Frank devises a plan to change neighborhood perception through goodwill. Meanwhile, Fiona plans a speakeasy party for Patsy’s Pies in order to drum up more business. Kevin and Veronica argue over what to do with Svetlana’s newly arrived father, Yvon (guest star PASHA LYCHNIKOFF).
