I wasn't for sure where to put this, but to clarify a few things, taken from the Rowling website.
1. Voldemort is not a cuddly animal, and Voldemort will not turn good. Stop trying.
2. Lily was not a former Death Eater, or anything of the like.
3. James, Lily and Sirius are all dead. For real.
4. Voldemort is indeed the last heir of Slytherin (meaning Lily and Harry aren't his children/grandchildren).
5. James is definately Harry's dad (I can't believe there are actually people out there who think that either Dumbledore or Voldemort is Harry's dad).
6. Draco isn't going to have a romance with a nice girl (this was taken from the World Book Day chat). Tom Felton is cute. Draco Malfoy is not.
