Dean finishes off his own sandwich, sets back to prop his feet up on the table again. Cas might not be buying it, but as long as he's not pushing for more, it's good enough for Dean. They'll deal with it later, right now they've got enough going on. He slurps down some of his own soda, glancing around the place in consideration. "Got salt lines for Meg and Crowley. Truth be told, though, I think your brother wants out of here just as much as we do. You really think keeping him off our team's the best way to play this?"

Not that he'll argue if Cas insists, it is still Lucifer after all. It's just that Dean's come to think of him more as an ace up their sleeve than an outright enemy. Common goals or whatever.
