Jade is the kind of girl people write horror movies about. She's gone from being rude, to insecure, to downright creepy, evil and mental in my eyes.
First she flirts with Drew, then she's rude to him, then likes him, then goes after Ed, then back to Drew, then Ed, then wants Tahan gone because she's prettier, then goes back to Drew then Ed, then wants to get between Drew and Tully so she can be in control of him, while also going after Ed. All the while thinking it's fine and other people shouldn't have feelings about that. Somebody needs to dump a bucket of water over her head and kick her out.
