Denis Leary

Monica blows back into town and immediately hooks up with Frank for more shenanigans, but the kids are left wondering if she's finally here to stay, and Frank is eager to pick up the ashes of his late mother and reclaim the cash he believes she's hidden. Meanwhile, after Fiona kicks out Lip, he kicks around with stops at Karen's and Steve's. Later, Sheila and Jody think the house is haunted by Eddie's ghost.
