I lovelovelove ambiguous!Snape; I write him quite a bit. He can be so creepy, and I love it when I manage to leave people wondering which way he'll go, with just that hint of ambiguity at the end! The one that I've managed this best in recently is my Santa's Lap story Keeping Hold of Harry. It's chan, which may squick you, but blimey, I'm so pleased with the way so many of the commenters were left reeling. I've written a very creepy!Snape with non and dub-con too, and some folk just can't manage that. I suppose it's an incarnation of Snape I don't always write, and my regular readers can be rather shocked when he appears! Do you think we both suffer from some strange compulsive disorder?
