Excerpt from "Ask Ausiello: Spoilers on 'Chuck,' 'Glee,' 'True Blood,' 'Grey's,' 'Lost,' and more!"
Question: Seems like a lot of crazy rumors are flying around about Supernatural’s big 100th episode — especially that bit about the major death. Please reassure my terrified heart that it won’t be either Castiel or Bobby. What would our boys do without them? —CY
Ausiello: There’s a death, but I wouldn’t exactly call it major.
Question: Can you give us some more Supernatural scoop for the 100th episode please? —Lizzie
Ausiello: Prepare to see Castiel like you’ve never seen him before: royally pissed off.
