Potioncat:
And it will throw us off track, because some of us will think "Oh, 
no!" (I certainly  did for a few pages in GoF) and others will 
think "I knew it!" but most of us will be going crazy while it's 
happening wondering "if".

I just hope the recognition of his loyalty and presention of Order 
of Merlin doesn't happen at the Hogwarts Graveyard at his funeral.

Potioncat:
Yes, you did, better some of us more ardent Snape supporters.  Now 
if Kneasy also starts defending Black, I'll be worried!
