Bucky's impressive scowl is the answer to that question, but it fades a little when he takes in what Steve is saying and the meaning behind it. Maybe most people might think Steve doesn't care, he puts up such a good front about not being bothered by his health problems or not letting his looks define him, that people don't realise how much it hurts him when others laugh or mock.

"You have to take turns? You mean you have to sit naked tomorrow for everyone else?"

He can sort of see why it would be done, make the artists do it so they'll always respect any models who go through it after them. But it seems unusually cruel to enforce it. Any models, after all, will have volunteered and thus agreed to do it, it's a different situation.

"Jeez, Steve, if you don't want to do it, don't let them bully you into it. But if you do it, then remember that you're just as good as anyone. A damn sight prettier than me now."
