I like Brian more, but only because I did not like him in the last week of BB2. I thought he and Elizabeth really attempted to turn Helen away from Paul, and his line "he'd fancy anything with blonde hair and a vagina" was well out of order. Any yes, his behaviour towards Josh was bad, though Josh did get his own back big time on the romantic dinners night.
Whether I like him as much as I did early on in BB2, I am not so sure...
