You cannot get the secret Question and Answer without the person telling you that. Its really good that you changed the email and all you can do now is hope the person doesn't call blizzard to reset security q and a and email. Which he probley will so you will lose it in a couple days. Congrats on getting your first account and just remember when you scam a account make sure you get ALL info including security q and a so there is no way he can get it back. =)
