I think the entity that brought Cass back to life is the same entity that pulled Sam & Dean into the plane. It seems to me that said entity was operating as a neutral party (to a certain extent) or would have only taken Sam (or Dean) depending on which side of the equation s/he is on.

I am beginning to wonder if this might be Michael. So many of the other arch(angels) are acting in his name when we don't really know what Michael himself wants.

Debt, I actually have thought that about Anna because Anna seemed so powerful. How was she so powerful, I wondered. I am still not sure about this notion. My fleeting thought now:

Is it possible that Cass is now Gabriel?

Wouldn't he know that?

aww fuck. you are probably right.

I didn't get the impression that Anna was one of the four who'd had direct contact when she was describing the situation. I suspect Gabriel is someone else as yet unseen and unmentioned.

My money's on Lucifer being the fourth.

That does make sense, as the falling out seemed to be intensely personal.

Didn't Anna say flat out she wasn't one of the four?

I feel like, at some point, she said that she hadn't ever seen God.

I feel like, at some point, she said that she hadn't ever seen God.

I think you're right. I think she said something about never seeing him directly, never speaking to him. So that's a no, then.

Hmmm.

Hmph

I think you're right, too!
