Do you think Kris from BB10 is Gay?

Does anyone find it strange the way Kris acts around Charlie? Like Freddie said in the diary room, he acts so spontanious around Charlie and although him and Dogface are ''a couple'' I think it's covering up something...He clearly doesn't really like her, he jes finds her attractive. But as the series continue I become more and more convinced that he's bi at least. Did you see him jump onto Charlie front to front. Two guys don't do that, especially when one of them is gay!
