[Helsinki Harlot]

Let me put a spoil on this-

Okay so we know for a fact that Misha Collins will be in at least 8 episodes so far. So far so good.

We also know from spoilers that we only see Castiel in flashbacks (as far as we know).

We know that Dean hooks up with Benny (stupid Benny) vampire in Purgatory and they come topside together and then this article makes me terrified - Especially the part about Benny.

We also know that since Castiel will only be appearing in flashbacks he may not have gotten out of Purgatory. Or something. It'll mainly be Kevin, Sam, Dean, and Benny. I don't know when Benny leaves but either way he'll be around for the entire season.
