Joey's health benefits lapse just as he develops a hernia. Meanwhile, Joey has trouble finding a new roommate. Chandler claims Monica still considers it only her apartment, resulting in a fight and Ross being the mediator. Monica flatly dismisses Chandler's idea to turn the spare bedroom into a game room. Ross denies to Phoebe that he loves Rachel, yet invites her to move in with him, all while Rachel is unaware they are still legally married. When Monica assures her they will, Rachel becomes distraught and seeks comfort from Ross, just as he is about to tell her the truth about their marriage. Rachel then upsets Monica by her blasé reaction, convinced Monica and Chandler will never go through with it. Rachel mistakenly believes all three will be living together until Monica explains Rachel has to move out. Joey reacts badly to the news, though Chandler reassures him their friendship will remain the same. Monica and Chandler announce they are moving in together.

Ross adamantly denies this and unsuccessfully attempts to secretly annul the marriage himself. Whilst he and Phoebe consult other women to see whether they would date him after three divorces, one of the women hypothesises that Ross is still in love with Rachel, to which Phoebe agrees. Ross promises Rachel to get their Vegas marriage annulled, only to shock Phoebe by confessing he cannot go through with it, unable to handle another failed marriage.
