The Office Romances: Dunder Mifflin's Most Memorable Couples
Jim Halpert and Karen Filippelli
Jim meets Karen (Rashida Jones) in season three, when he transfers to the Dunder Mifflin Stamford branch to take an assistant manager position (and to get away from Pam, who rejects him at the end of season two). When the Stamford branch closes, he and Karen move back to Scranton and begin a relationship. However, Jim's unresolved feelings for Pam come between him and Karen, and he eventually breaks up with her.
