What the hell is Steve's obsession with the pizza?

Bucky glances over at him in mild confusion, before it twigs that maybe it's a coping mechanism. God knows that he knows what it's like to fixate on something irrelevant and seemingly meaningless in order to keep the more pervasive thoughts at bay. Whatever was going on with Steve must be frightening, and maybe he was in pain or discomfort that he wasn't talking about.

"Steve..."

He reached out and put his hand on Steve's leg, gentle and careful.

"It's gonna be okay, I really mean that."
