I see Brian as a calm bloke, i think he has a gentle soul, he got very angry last night because of the torment he has had to suffer daily, in real life he would have walked away or maybe never to even be in that situation in the first place.
I didn't watch the year Brian won, did he show any aggression or anger whilst there?
I know he won, and everyone says he won because he was a lovely great guy, how could it be that this lovely, great guy win his year, yet with Helen he looked like he wanted to kill her
I only have to assume that Helen is the reason, most people can reason and iron out any conflict yet Helen has the ability to make even the nicest person that angry.
