I can see a Shahbaz situation developing with Simon
 

The man has a serious personality disorder and the housemates are already bullying him en masse.

It is compelling television but i can't see it lasting too long.

Problem is, I don't think they can ever really bother him due to his psychopathy, so he will stay and it will get worse and worse.

Good

why does he have a personality disorder

doing the most

the people in bb7 were vile, they put Helen in a good light. the way they stole shabaz's clothes while he was swimming and locked him out made me sick. nevertheless they've gone too far because at the end of the day he had to nominate someone.

Probably his upbringing.

yeah but why do you think it?
