Harry Potter and the Half-Blood Prince (Spoilers)

[Ali Ahmed]

Okay here goes my thoughts.
I think that Dumbledore did indeed die. It think he froze Harry to protect him and not anybody else. I don't think that it was somebody using Polyjuice Potion because there was not a time in during the last parts where Dumbledore could have switched with somebody else.And just to throw out a question, who in the world is R.A.B? I'm guessing that we will find out in the 7th book or it might be someone that was mentioned only a couple of times but is very important. But it was still a very good book, the best in my opinion.
