Yeah, フレッド Weasley dies in the 7th book! It's really sad because George was like his best friend...even closer! Plus the Weasley twins were a really funny part of the books, and now that there's only one half of the whole is the humor gone?
Yes, it was in the novel.. hoever did everyone else know that his twin george actually dates fred's ex Angelina Johnson, ( a former quiditch team mate) in the future and they get married?? a true fact stated によって JK herself....lol
