Thats still very much a part of purgatory and what makes it so dangerous.

And for those wondering, yes, there are still Leviathan there.

But the Leviathan wont be the focal point of the purgatory story.

Rather, its about what Dean and Castiel are going through.

As for Sam (Jared Padalecki), hes stuck with Chuck (Rob Benedict).

God knows everything about Sam and Dean, Dabb reminds fans.

He knows all their past traumas, all their emotional trigger points.

Chuck is a petty person when it comes to the boys.

But the hour will offer some answers in regards to Sams connection with Chuck.

How can I make it work for us?

Is it going to be a thorn in my side for the rest of my life?

And thats a question that gets answered in episode 9, Dabb says.
