Phoenixgod2000:

This has to be brief. I'm on the road for a job interview but I just 
had to chime in a little on Snape.

First of all, let me say that I am not totally convinced one way or 
another. If the prediction contest taught us all anything it is that 
an authors mind is a deep and guarded place.  That having been said, 
the mental gymnastics needed to justify Snape are staggering.

throughout the book Dumbledore struck me as someone who thought he 
had more time than he did. He was always putting off questions until 
a future meeting.  He didn't seem to have prepared anyone for his 
eventual death, which if he thought it was inevitable he would have 
done.  When he was at Draco's mercy he spent the time trying to 
create a situation in which both of them could survive. He was 
offering Draco and his mother his and the Order's personal 
protection. He was trying his hardest to convince Draco, not just 
for Draco's sake, but his own. He gave every indication of wanting 
to live. until the moment Snape walked in the door, DD was trying to 
create a win-win situation between he and Draco. Why did Snape have 
to stun Flitwick, the only charm master probably powerful enough to 
break the death eater only barrier on the tower enterence. there 
wasn't anyone around, so he didn't have to keep up DE pretenses in 
that moment.

I can only conclude that Dumbledore wanted to live and Snape finally 
revealed his true colors.

of course on the other hand, Snape didn't try very hard to hurt 
Harry in their rather one sided duel until the very end. Something I 
found very odd. Either Snape was under orders not to hurt Harry from 
Voldemort or he didn't really want to hurt Harry to begin with.

So when is book seven coming out?
