Angel's eyes narrow slightly at Mulcahy's use of the word 'trapped', but he keeps the thought behind that to himself.

Instead, he asks a tangential question: "were they all dead? The people who arrived where you were last, did they get there by dying? I think...that's part of something that a lot of us, maybe all of us, are walking past and the locals are letting us."

Someone pointed out to Angel that he'd been bottling up the trauma of being chopped to pieces, destroyed completely. And he's realized everyone else is, too.
