NOTE: I personally don't feel that this is a spoiler, since it doesn't give away any actual plot or anything. HOWEVER, if you feel that seeing what Blaize Zabini really looks like would ruin your enjoyment of the book, then DON'T click!

What does Dumbles trust snape? WHY WHY WHY WHY WHY? For me this book only solved one question of why Volders could not be killed. I think I expected way too much.
