At his apartment, Ross is still in bed, fast asleep, when he's shaken up by the voice of Chloe. As he checks the answering machine for messages, he hears a message from Rachel, saying that she loves him and that she'll drop by his apartment. Ross doesn't get rid of Chloe in time and hides her behind the door as he opens it to find Rachel standing in front of him. Ross promptly agrees to be her boyfriend again.
Ross doesn't waste any time in confessing everything that happened last night to Joey and Chandler. Chandler thinks Ross is crazy for cheating on Rachel, whilst Joey urges Ross to find out "the trail" - the list of people between the girl he slept with and the girl he doesn't want to find out what happened. Ross traces the trail from Chloe to her colleague Isaac, who has a sister Jasmine, who works with Phoebe, who is friends with Rachel. What Ross doesn't trace is the trail from Jasmine to her roommate, Gunther, who without hesitation, tells Rachel everything.
Phoebe and Monica try out Waxine from the TV commercials, but the pain is too much for them. Joey and Chandler rush to their aid, but before they can get out of the room, Rachel storms in the apartment, followed by Ross. Phoebe, Monica, Chandler and Joey stay in the room, unbeknownst to Ross and Rachel. The fight between Ross and Rachel is worse than last night's. Rachel gets even angrier with Ross - she discovers that Chloe was still in the apartment while she was there getting back together with Ross, she's furious for finding out from Gunther and she mocks Ross by trying to fantasize being with Mark in front of him.
Meanwhile, the guys eat the Waxine, which happens to be organic, but not really edible. Joey says he thinks he needs a new walk. It's late night now (actually soon 3:00 a.m. as said by Monica), and Ross is still trying to make Rachel forgive him. Just as it seems that Rachel might try to start thinking about forgiving him, he starts touching and kissing her. She slaps him away angrily and tells him to go. Ross suddenly walks towards her and tells her that there's got to be a way they can work past this. He tells her that he can't imagine his life without her and they both start crying and Ross gets down on his knees and holds Rachel. Rachel says that she used to think of Ross as somebody who would never ever hurt her, but everything has changed since now Rachel can't stop picturing Ross with Chloe and everything has changed. Ross continues to deny the end of everything between them, stating "this can't be it". Rachel sadly replies: "Then how come it is?"
Meanwhile, much later, the other four are able to get out where they find Rachel still in her clothes and sleeping on the couch and Ross is gone. Chandler asks Joey if he's done a new walk and Joey answers "No, I really have to pee."
