When Casey sprains her ankle because of Derek, she gets whatever she wants(including the chair that Derek always sits in, and his tickets to a White Stripes concert) and Lizzie does everything for her, making Derek jealous. He then fakes an injury, making Casey do everything for him, and when Marti cuts up the tickets to make a picture, Derek accidentally reveals that he was faking the injury by running up the stairs, and Casey does the same thing. Then, Lizzie and Edwin get whatever they want.
