"What the hell was it doing inside that thing?" No. That doesn't matter and anyway, Dean can guess. He heads back to Cas. "Neither of us can pick that up--help me get him over to it!"

If it's Grace, then Dean was right and Cas is going to be fine. If it's not...Dean's just not going to think about that.
