Is Cass dead, or still in purgatory? I hope they bring him back to the show I miss his smile n eyes.

In Dean's flashbacks from the second episode, it looks like he might have let go of Castiel's hand when he left purgatory. I'm guessing that he's still in there and the reason that Dean says he's dead is because he regrets leaving Cass behind.

well I haven't seen the 2nd episode yet but in the 1st episode dean said that Cas died ...but somehow I didn't really believe him! The way he said it just didn't sound very convincing to me! I think not even sam bought it! so I think Cas is still alive somewhere!
besides everyone loves Cas! The writers would be crazy to kill him off!

Cass is alive

I'm not sure - Dean intimated he was dead but even if he is this is "Supernatural" and dead doesn't always mean dead forever!!!!! So don't despair I'm sure Cas will be around in some form or other - even if it's only in flashbacks.

I saw some photos from the set recently (they are all added here in the photo section of the club) with Cas very much alive and kicking
