Liz confesses she got back with her ex, because he asked. Jack Donaghy fears that Liz is leading a life of mediocrity and takes it upon himself to be her mentor. Meanwhile, back at the show, Liz needs to deal with a physically-altered cast, including a face tattoo on Tracy; botox and collagen injections on Jenna and Josh sporting two black eyes from a run-in with an angry Regis Philbin.
