Well, he's a very good ploy because I really couldn't tell whether he came from some other fandom or if you'd made him up for the story. I think it was your description of his appearance that did it for me; very specific and the added bit that it made him look somewhat creepy.

I'd really have to do some braining storming if I wanted to continue this. Which is pretty much why I brought it up; would be a hard one to come up with. I'm having the same trouble on one I'm writing. Wanted to have Spike, vamp!Willow, and vamp!Xander kill Buffy but I realized I just couldn't see how it would be done. And then I realized I think of Buffy as being pretty much unkillable so I decided not to go in that direction with it. Unfortunately that's making part of the story less believable. Wow, which must be really bugging me given how I'm rambling on about it. Oops. Sorry.
