what episode does holly come back to the office
Holly Flax In "Classy Christmas", Holly returns to Scranton to fill in while Toby is away at jury duty. The initial excitement about seeing her old friend again turns to anger when a jealous Michael vandalizes her Woody doll (a gift from her boyfriend AJ). Holly divulges to the women of the office that AJ won't commit, and she's going to give him an ultimatum to propose to her by New Year's. When Pam tells Michael, he is cheered up by the news, as well as Holly lying to AJ about how Woody got damaged.
Finale (The Office) The following day, a panel is held for the office so that audience members can ask them questions. Dunder Mifflin CEO David Wallace (Andy Buckley) openly states his distaste for the documentary. Pam Halpert (Jenna Fischer) is pressed with questions about why she did not allow Jim to follow his dream after he has paid her so many romantic gestures. Jim attempts repeatedly to disperse the resulting tension. Erin Hannon (Ellie Kemper) finally meets her birth parents (Ed Begley, Jr. and Joan Cusack) who had put her up for adoption.
