I'd say that basing their VTs on their personality in the house, these people have lived up to their expectations in the house:
Lisa - proved she was Mario's pet.
Luke - He really does follow the rules that he set in his audition VT (as much as I dislike him..), but he hasn't worn any suits!
Sara - She admitted she wasn't "Sweet as pie", and she didn't really sell herself to be anything else.
Darnell - Although his VT really only showed that he was albino, he hasn't really lied about any aspects of his personality.

..and that's all that I can really think of. Who do you think has lived up to the personality they sold in their VT?
