I know that this topic has been touched on many, many times, but it just seems that JKR was preparing us all through HBP for what Snape did.  Not that any of us expected for him to kill Dumbledore, mind you, but for the fact that Dumbledore could have been mistaken about him.  He made several comments about, "an old man's mistakes.......", but you thought he was always just referring to Harry.  He always said he had no question as to where Snape's loyalties lie, but never said why.  I could be way off on this idea, but I was just wondering.....
