Season 1 Edit
Katy is a hand-bag saleswoman. Both Dwight and Michael try to woo her, but to no avail. Michael thinks he has a fair chance with her until Jim gives her a ride home.
Season 2 Edit
Katy is revealed to be dating Jim. In The Fire, Katy participates in the Desert Island game with the other Office staff. She chooses Legally Blonde as one of her top movies, which elicits a laugh from Pam (due to the irony of Jim previously mocking Meredith for choosing the same movie). In Email Surveillance, Ryan asks Jim if Katy was coming to the house party, but Jim responds that they hadn't spoken in a while. Ryan asks if he could call Katy, which Jim rejects. Pam overhears and appears surprised, but secretly happy. She was a cheerleader at Bishop O'Hara High School, a rival school of Roy's, and the two later recognized each other when they met on the Booze Cruise. Jim dumps Katy while aboard the 'Booze Cruise' after he saw Roy and Pam together and said they would never be as happy together as Pam and Roy.
In a deleted scene, Pam defends Dwight's gun shooting incident from earlier in the episode and reminds Jim that he did save him from getting attacked by Roy. Jim responds that Dwight would be getting a free pass for being less violent than "the goon you were engaged to". Pam rolls her eyes and says that Roy was a lot smarter than Katy. Jim's reaction indicates that they had spoken about Katy a few times off camera. (Dwight K. Schrute, (Acting) Manager)
