Now living with Sean, Fiona attempts to get his son, Will (guest star Reed Emmons), to like her. Will slowly starts to come around, but when he snags a gun from Carl at the Gallagher house, Sean catches him and is furious with Fiona, worried he'll lose custody.
Fiona tries to make amends with Sean, who isn’t giving her the time of day. Meanwhile, Debbie and Queenie travel to Queenie’s rural commune along with Frank who is trying to escape G-Dogg (guest star Na’im Lynn) who’s after him for stealing his drugs.
Sean officially moves into the Gallagher house as Fiona — intent on getting her marriage right this time — sets out to plan a traditional wedding, bachelorette party included. Elsewhere, Kev is still not happy about V and Svetlana's pending green card marriage and tries to find a way around it by paying to get her a new identity. While he is off getting scammed, the girls take matters into their own hands.
In an effort to be a part of the wedding, Frank offers to pay for the reception and goes scamming around town to raise the money. Sean, who's been butting heads with Frank since he moved in, is worried Frank will just end up hurting Fiona and confronts him on it. Things turn physical and both men are injured in a brawl.
It's wedding day and Debbie shows up at the church with Franny. Ian finally brings Caleb to meet the family. Frank shows up uninvited and high, and he reveals that Sean is still a practicing junkie. Concerned about preserving his relationship with his son — who is shocked by the news — Sean does everything he can to keep Will in his life.
