Did you know that Snape is on Dumbledore's side and got killed by Voldemort in book 7?

You're wrong. Fred is killed by Augustus Rookwood. Ron and Hermiones kids are Rose and Hugo. Not Victoire. Victoire is the cousin of James, and is probably Bill and Fleur's daughter. And even though posting spoilers isn't exactly nice, people should be smart enough not to go online and not look at stuff like this until they've finished reading the book.
