[Damon floats in the water, dressed in the swimming suit God gave him (aka: nothing at all) and savoring a peculiar feeling of peace.
He catches sight of Jae-ha's leg before he notices the rest of the other man; it is rather attention-grabbing. For a moment, he's not sure whether to call out or not. Sure, he's met people who've had worse childhoods than his before, but that was generally when his humanity switch was flipped off. Having walked in Jae-ha's dream and seen what he saw with his humanity fully functional (well, as functional as it ever gets)... it's uncomfortable. And Damon doesn't do uncomfortable.
But that's an inhibition, and this particularly prison is designed to destroy inhibitions, so before he has too much of a chance to really think about it, he finds himself calling out.]
