Ask Ausiello has posted a “Supernatural” spoiler.
Question: I’ll send you some birthday cake if you give me some Supernatural scoop about the 100th episode. —Annie
Ausiello: In the milestone episode, airing April 15,”a very important character will sacrifice themselves in a suicide mission,” reveals exec producer Sera Gamble. “We definitely kept in mind that this was [an important] episode. We wanted to deliver something with real scope; it’s about the Archangel Michael. Crises will come to a head for Dean and Castiel. And you’ll see characters you never thought you’d see again.”
I would be so wildly disappointed it Castiel or Bobby sacrificed themselves, but who else is there, what other important characters are there, other than Sam and Dean themselves? It’s possible one of them sacrifices themselves and is brought back. They’ve killed off every other important character, so it has to be one of those options. If it’s Bobby or Castiel, hopefully, they are brought back as well. I like them too much.
