How come Alex has one and Dennis hasn't?
Well I like him - I think he's genuine and doesn't have a bad bone in his body.
Also he hasn't shown the stereotypical 'bitchy' male gay housemate traits we've seen in the past, bucking the trend.
I think he's being penalised by the friendships he's made in the house so far. But at least he's not aligning himself to people just because he thinks they're popular.
Additionally, he makes me laugh when he gets excited.
Someone else must like him.
