I misread the brothers' affection before I even knew he was gay, but you're right, he really doesn't help himself with how camp he comes across on the show.
Last night they were over-playing the "he's just like a child!" thing again. They've not really developed that story, all we've had is Jake saying he's always picking up after him and it all seems like a, 'Of Mice & Men: George and Lenny' relationship. Would have been better if they'd given us more background on it.
I agree, Gary and Minty are awful. They remind me of the kind of pointless characters they have on Coronation Street whose only scenes seem to be in the pub on a lunch break with each other, like Sean. They're totally pointless. And, although he's hardly on it, and because he's hardly on it, Juley??
