A few weeks ago I read a fan fiction piece that managed to bond Harry and Snape and make them friends instead of enemies. At first I was put off by it, but it was so well-written...
I've now been sucked a new 'ship. Not romance, mind you, but stories where Snape ends up being Harry's substitute father figure/friend/mentor. I'm completely disgusted with myself, but I can't help it. I love it. Most of the writers set the stories pre-HBP, I think because they're scared of trying to fix THAT ending. I'm still looking for someone with enough guts to attempt it.
So yeah. Go Snape.
