I voted "who is Stuart" . In the house for most of the time I didn't like him. Everytime he did those confounded "hey. Look how fit a poser I am workouts". I could have thrown a brick at the screen. The truth is I just don't know Stuart's personality out of the house!
He does seem to be trying to portray himself as good guy since leaving ( Maybe he is!!). But it leaves me with the impression of a man in denial about his own perception of himself.
