 At Christmas time, Sarah and Bailey host a tree-trimming party at their apartment where Bailey s friend, Will, arrives for a visit and discovers that he and Bailey now live in separate lives due to Baily being with an older woman and his lack of party spirit. Julia s former boyfriend, Justin Thompson, also arrives for a visit where he tells her about his Ivy League college life, which prompts Julia to lie to him about her so-called successful life. Meanwhile, Charlie, at his doctor s advice to "recharge," accompanies Kirsten on a long-distance road trip.
