If Steve met This Guy on the street, he would immediately dislike him for the nature of that smile.

"Yeah, you're fine. Just a little make-up routine for the aesthetic." He is... cranky as hell right now. "Stop being a fucking idiot before Fire, Brimstone, and Sadism over there remembers he can use me as leverage."

What? Is he leveraging himself weird? Maybe, but shut up.

Also Steve really needs to not be dismissing the actual devil right now, but he sure as shit is not Steve's priority.
