Shameless

Frank goes on the wagon, which pleases Carl and Debbie, but a skeptical Lip doesn't believe their father's newfound temperance will keep him from the bottle for long. Elsewhere, Fiona scrambles to find a better-paying job, which leads her to overlook some suspicious behavior of Steve's; Kev and Veronica open their house to a foster child and get quite a surprise when they learn her family history; Ian pursues Mickey; and Sheila worries Frank has lost interest in her.
