Pratt manages to not grimace, but it's a struggle. He'd seen the man's fingers, he knows that the rest of him likely looks the same. But it's certainly different seeing the man he knew, the one who'd been very alive and always seemed to look presentable, seeing him look so torn and disheveled really drove home what had happened to him. It's not even so much the fact that he can see his bones and muscles, though that's very unsettling in it's own right, it's that he knows that if it was up to Carlisle even that would be in pristine condition. The ink stains must drive him crazy.

He's still not sure that drinking it is a good idea. How would he digest it? But he figures that Carlisle will know best.

"Maybe one of the fancy contraptions in the kitchen can make something that'll work. It's not magical, it's just advanced tech but who knows. Unless this works?" He sounds vaguely hopeful, because he just wants Carlisle to have at least one good thing in his life.
