At first I was going to ask for Rodney McKay. Not because I like the character. The opposite, in fact. But I've always liked the way you don't whitewash his jerkiness or pretend that it's actually believable that the other characters find his selfishness charming (e.g. your recent kink-meme story which has forever ruined any McShep bondage story for me). But then I remembered how much I liked Dave Sheppard in Dreams We Never Expected, so this is a long of saying, Dave Sheppard please?
