Monica quickly realises that Chip has never matured beyond high school and dumps him. Monica runs into Chip Matthews, Rachel's high school prom date, and is thrilled when he asks her out, though it causes tensions between her and Rachel (and ultimately Ross). Phoebe goes to see her sister, Ursula, who reveals that she already knows the truth about their birth mother. Joey and Chandler come to Monica's rescue after she is stung by a jellyfish - one of them has to pee on her leg to relieve the pain, as suggested by Joey who has learnt it from watching the Discovery Channel. Ross and Rachel then break up again after he refuses to take all the blame for their previous problems (as have been stated in the letter) and insists they were 'on a break'.

Ross falls asleep while reading the letter, and unwittingly agrees to take full responsibility for their break-up later on. Ross breaks up with Bonnie in order to get back with Rachel, who prompts him to first read her 18-page letter discussing their relationship and previous break-up.
