First: Jade
Never liked her since the moment she entered the house.
She keeps moaning about how bad people are, while she's really the worst of the lot. Talking behind peoples backs etc.
Also, I think she's too young mentaly to be in the house. The whole experience will surely ruin her for life once she leaves the house and finds out what people really think of her.
Second: Sophie
She's only got two faces. Her serious (rather boring, slightly twitchy look), and her half smile half grin. She's so extremely boring, and always changes conversations into being conversations about her and what she thinks.
She never tried integrating with the rest of the house while Lee was there (maybe because he was stalking her all the time), but I think that's a really bad excuse.
