Season 4 picks up three months after Season 3 and sees Darcy return, reluctant to talk about where she's been and determined to reunite with Steph. Having spent much of Darcy's absence questioning their relationship and her unresolved feelings for Emily, Steph is in no hurry to forgive. Even Kristen appears to have moved on, juggling her drug addiction and penchant for anonymous sex with a new job in family law.
