i do wonder -- and i hope you read the later comments and see this question -- why you chose to put Colin in Slytherinn?

I pretty much see Colin as sort of a non-character in the books -- he's there as a convenient plot device. He worships Harry, and since he hasn't much of a personality on his own, I figure he'd follow Harry wherever Harry went. :)

what did Harry and the hat say to each other? Did he simply say something like "not a bad mind, either.. .there's talent, there... yes... and a hunger... you could be great and Slytherinn can help you to greatness..." and Harry say "ok"...

I dunno, really *grins* I don't see his being placed in Slytherin as being "tempted" -- Harry never dictated where he wanted to be put, I don't think you can dictate that. Harry was put into gryffindor because he didn't want to be a part of what Slytherin was associated with -- not because he said "Not Slytherin". Here, he associates Slytherin with positive things, so there's no antipathy towards it.

I guess what I'm saying is that it wasn't up to Harry -- the hat put him where he best fit in. :)
