I find that the James we are seeing in the house and the James that was present during the Apprentice were two separate people. James came across as very misogynistic as he would only pick arguments with women who he felt were weaker than him like Roisin. He would also argue in a very ugly way:
Reflecting onto CBB, the only person he's fought ferociously with was Farrah when (although Farrah was mostly in the wrong) there was one time in the lounge when I thought James was going to push Farrah.
Anyway me thinks James' personality in the house is mostly false and he's trying to hard to meant his 'hard' image.
