He hires Wendy as his assistant, and tries unsuccessfully to hide the truth from Kate. Kate gets jealous and storms off. While at the Warsaw, Drew receives a call from a panicked Wendy, who fears that her ex-boyfriend has tracked her down. Mimi overhears and suspects that the whole thing is a ploy to get Drew into bed. Drew begins to agree with her after he arrives at Wendy's apartment to find her in her underwear. She claims that her radiator is broken. Even after Wendy's ex-boyfriend shows up, Drew still believes it is a scam. He changes his mind after the guy punches him.
