Unless they've decided to be done with this batch; who knows. Dean isn't going to let go of the idea that this could be it for everyone until they get out of here, and it's mostly because that's his stubborn, survivalist, un-hopeful way of thinking, but it's also a manifestation of how scared he is that not just him, but everyone here he cares about won't get out of these tunnels alive.

"Yeah, I'd like to keep it that way, so long as they aren't occupied with me."

Dean's worried about Cas. And Alfie. The other angels, meh.

Since they're both checking some of their bravado, Dean wonders if this should maybe be the time that he says the T-word for what Raphael did for Sam.

"I heard you patched Sam up." ...he'll work up to the T-word.
