Kathy (Paget Brewster): Joey's girlfriend, introduced in "The One with Joey's New Girlfriend" (airdate October 30, 1997; Season 4, No. 5), with whom he has nothing in common apart from both being actors. A mutual attraction develops between Kathy and Chandler, which manifests as a kiss; after Joey finds out, Kathy decides to leave New York for Chicago, and declares her love to Chandler. Initially outraged at Chandler's betrayal, Joey has a change of heart after Kathy's speech, and she and Chandler get together. Although Chandler was initially uncomfortable about the possibility of their relationship becoming sexual as he would be directly compared to Joey, Monica and Rachel were able to give Chandler some pointers. Sometime later in the season, Chandler goes to see Kathy in a play and discovers that it has extreme sexual content with her male co-star, Nick. Chandler starts to suspect that she is cheating on him and confronts her about it. Kathy is offended and gets into an argument with Chandler, and the two do no not speak for a while. Realizing that he had come to the wrong conclusions in their argument, Chandler arrives at Kathy's apartment to apologize to and make up with her, only to find himself yelling at her when he finds evidence that she has now slept with Nick after their argument, and they break up.
