If you ask me Katie and his so-called bad treatment was the best thing to happen to him. It overshadowed the fact that he was actually quite a dislikable person at times with rather nasty practices himself.
I mean he told tales, always quick to blame others for his own errors showing little or no honour or loyalty to anyone.
I mean for example his first project leader task, his idea of team support was to belittle people and sell them out when things went bad. Like when that fellow pointed out they couldn't use 'natural' for their lollys he lumped the blame for everything on Natalie, which while she was to blame and wrong for not following his orders in regards to the name of the lolly on the label he conveniently forgot that he hadn't seemed to find this an issue for the best part of a day or two and had quite happily had her go out sorting posters and whatnot advertising they were 'natural'. He proceeded to have a temper tantrum, quite selfishly making Natalie feel bad about herself while playing the victim himself.
He also lied to get Ghazel in trouble and himself out of it and twisted the whole Katie and Paul thing for his own advantage.
While I may not agree with his 'bullying' or 'treatment' or whatever he wants to call it I can understand why his fellow competitors didn't like him much because from what I was watching he wasn't this 'nice lad' people profess he was. He just caught the scorn of someone even more 'evil'.
