Well, I heard someone would die in this book and my guess was Dumbledore. Well, I had a few guesses and he was the main one.

When they were talking about what Draco had to do, at the beginning of the book, at first I thought kill Harry, then I thought, no, that would be dumb. I then thought "Kill Dumbledore" and I thought that would go along with my theory on Dumbledore dyeing, especially since Snape gave the unbreakable vow.
