Wash just waves a bit as he's gestured towards. Yep, that's him, stranger in a strange land. "To be fair, this isn't actually the worst place I've ever been dragged to." Somehow, the crumbling illusory world is not actually worse than prison. Go figure.

He watches Yondu, and listens, and looks back at their informant. "So it's dead, but it left something behind." It sounds like a minor point of clarification, sure, but so far as he knows, the Hunger doesn't leave anything in its wake - it obliterates dimensions and moves on. If whatever's eating worlds left a corpse, then it's not the Hunger, and that's one less thing to worry about (on an admittedly extensive list of things to worry about).

"If we don't know what's eating worlds, then what do we know about Diagad? This one or the real one."
