Oh, wow! I don't think anyone's ever thought of Quirrell/Lockhart before! :-) Lockhart's behavior towards the end was intriguing. And I love the fact that the possession was something against Quirrell's will. I had always believed that myself; then again, I guess I look at all the character empathetically. :-)
I wish there are more Quirrell fics out there, and I loved this. Thank you, mystery writer!
