It's a curious thing, what death does to a body.
Not true decomposition—Danny hasn't cared to look up that kind of thing; being dead doesn't automatically mean his stomach is any stronger than it was in life. But he can see, when he looks in the mirror, sometimes, echoes of Phantom.
It's not obvious. It's the sort of thing only he notices, because it's his body, and oh, that's new. And, also, it might literally be only something he can see, gaze deathless.
Vlad has it too. It's… there's a translucency, to both of them, a sort of flickering quality that shouldn't be possible for flesh and bone but is. None of the living acknowledge or seem to see it, but there's something insubstantial to their very essences. Death creeps in, given a route, and here is the decay.
He thinks that, given long enough, his human body might just fade away, Phantom in its place.
He doesn't know how to feel about that.
