Severitus Challenge

Proposed by Severitus back in 2001.

1. Severus Snape must be revealed to be Harry's father (no..not James, though that would be interesting……MWAHAHA!!!)
2. Remus Lupin must have returned to Hogwarts for some reason or another (unless it's a 3rd year AU, in which case he's already there.heh)
3. Harry must undergo some progressive physical change starting on his birthday. No tada! and suddenly he looks like Snape, at first anyway.
4. The story must be based mostly around Harry and Snape
5. (optional) if you want, feel free to take one of the conversations I've got posted here. Change 'em however you want, they're mere clutter on my harddrive right now, and I hereby bequeath them to you.
6. Make note somewhere that it's in response to this challenge, so all the other nice people can give it a shot too, if they want, or be able to find the other challenge responses.
7. PLEASE LET ME KNOW! I WANNA READ 'EM! Feel free to either email me or let me know in a review.
