So, everywhere I've read or been directed to, we've gotten the gist that JKR took Alan Rickman aside and told him something about the role of Severus Snape.
No where have a found the words he said(no where verified that is). And Alan himself is rumored to have said that she didn't tell him anything that was part of the story outline.
I would like to hear different theories from everyone on what JKR could have told Alan Rickman about the role of Severus Snape.
My own theory is "Severus Snape is a deeply honorable character."
But then you think that JRK based Severus Snape on a teacher she rather disliked and you wonder.....
So, what is everyone else's theories?
