Jade replies, "I hooked up with Daniel, your ex." Tori lies and says she feels great about it, but the lie becomes less of a lie later. It become less of one when Tori catches Beck's other ex-girlfriend, Alyssa Vaughn coming in to try to steal Daniel in revenge for Jade taking back Beck in the episode "Jade dumps Beck." Jade ends up convincing Tori to help her and Tori talks to Cat about it, causing both to stop Alyssa from stealing Daniel.
