Potioncat:
Oh, I thought that even before this book. In fact, I went into DH 
wondering how it would really turn out. While I "felt" Snape would be 
some variation of DDM, I knew there was enough evidence for it to work 
the other way.

I think JKR did a great job of creating the Snape she did. He doesn't 
really fit what I expected, and he doesn't fit what the Sanpe-foes 
expected either.
