Question: Any truth to the rumor that the Winchester brothers will be hunting a Smurf on Supernatural? If not, then you got any legit spoilers for the show? Answer: Yep, but what I have to reveal may be less exciting to Supernatural viewers than it will be to Charmed fans: The show is introducing a trio of witches! OK, two witches and one sorceress who may not be exactly what she appears to be. What, you didn't expect me to give everything away, did you?
