Have you ever wondered why is Hermione is so smart? How does she know stuff on N.E.W.T. level.. Has she been trained by Voldemort ? Mayby her parents are not muggles (also known as humans) maybe her parents are a wizard and a witch who work for You Know Who. If you do not know who Voldemort is (ahh i said his name) he's the Dark Lord and Harry's nemesis.  Maybe Hermione just wanted to get close to Harry to let Voldemort kill him and she could earn a reward. Maybe that is why she took muggle studys to pull of the trick by knowing it all.

I wonder who is Hermione Granger really ? Who do you think she is?
