We really hope that Snape is not a bad guy, but its hard to imagine a scenario where he is not. Still, something about that last scene between them did not seem right. We're wondering if Dumbledore ordered Snape to kill him, Dumbledore is so accomplished at Legilimens and so is Snape, that its possible that they were able to speak or at least get the idea across. We were wondering whether Dumbledore was pleading with Snape to kill him and thus follow orders, rather than begging for his life. We find it hard to believe that in all that time Dumbledore couldn't have figured a way out, even weakened and without his wand. Suddenly became fans of Snape in this book, so heres hoping he's not evil.
