In his latest spoiler column for Entertainment Weekly, columnist Michael Ausiello introduces a new game: Ask Eric Kripke!

The Supernatural creator responded to a number of viewer questions, including inquiries related to Ruby's knife and other topics. Here's what he had to say...

On Ruby's knife: “I don’t think I’ll ever give up the back story of how that knife got its powers. I like to leave some things mysterious. And that’s likely to remain mysterious.”

On the Colt pistol: “The Colt pistol is making a comeback. I was actually in the [writers] room today breaking episode 10 and the cult pistol is in episode 10. And it also pops up a little bit earlier as well. The cult emerges as the boys’ best strategy to shooting the devil in the face.”

On the return of Jeffrey Dean Morgan: “I would love to have him back. But he is an in-demand actor. It’s all about scheduling. It’s [in the hands] of men who wear ties.”
