Tawni breaks the pact and Sonny starts to think about Chad Dylan Cooper, but Gilroy knows that is a face of someone who has a boy crush. Gilroy brings Chad out (Chad thinks he's there because of a book he read) and shows a clip of him and Sonny sharing a rather romantic moment from Episode 2. They both go backstage and they don't realize there's another hidden camera and everyone is watching them. Sonny and Chad are about to tell each other what their feelings are for one another, but Tawni, feeling she owes Sonny, grabs the remote and turns off the camera so Gilroy and the studio audience can't see what happens. Gilroy turns the camera back on and sees Sonny saying "That was so much easier to say than I thought it would be," and then walking away with Chad.
