I think Dexter is a genuinely nice guy who has put on a front with all the womanizing crap. I think he's a bit socially awkward and has never had many friends because he's a bit different and was probably an easy victim for kids (and cowardly housemates!).
He puts people like Wolfy, the twins and Hazel to shame and i'd much rather have him as a friend than any of those three.
I think, if he plays it smart when they go back in, either him or Gina could win this year's BB.
