Rachel quits her job at Central Perk and begins working at Bloomingdale's, an upscale department store chain. Ross soon becomes jealous of her colleague Mark and frustrated by Rachel's long work hours. She is tired of his constant jealousy and insecurity, and decides they need a (relationship) break. Ross, hurt and somewhat drunk, immediately sleeps with Chloe, "the hot girl from the Xerox place," causing Rachel to break up with him completely. Although Phoebe initially believes she has no family except her twin sister Ursula (Lisa Kudrow), she learns she has a half-brother, Frank Jr. (Giovanni Ribisi) and discovers her birth mother, Phoebe Abbott (Teri Garr) over the course of the season. Joey falls in love with his acting partner Kate (Dina Meyer), but is jealous of her dating the director of their play. They begin a brief relationship that ends when she takes an acting job in Los Angeles. Monica dates millionaire Pete Becker (Jon Favreau), despite her initially not being attracted to him. However, she breaks up with Pete after he is seriously hurt trying to become the Ultimate Fighting Champion and refuses to quit. Phoebe sets Ross up on a date with her friend, Bonnie (Christine Taylor), inciting Rachel's jealousy. She tries sabotaging the relationship by coercing Bonnie to shave her head bald, and eventually admits to Ross that she still has feelings for him. The season closes with Ross having to choose between Rachel and Bonnie.
