Tilly only features in only one episode. She plays Eddie Menuek ex-girlfriend. Eddie is a former roommate who lived with Chandler in the brief period that Joey Tribbiani moved out.When we begin to learn that Eddie is a bit weird, Tilly drops off Eddie's fish tank to the apartment and when Eddie arrives back he accuses Chandler of sleeping with her.UPDATE: At the quote section below, it say that Tilly tells Phoebe how much the studio is costing. This is SO wrong. Tilly wasn't even there! It was the record producer who said it! The only episode Tilly is in is the one where she brings the aquarium to Eddie, then Eddie accuses Chandler of sleeping with her.
