Then he keeps talking to a devil, because what else is he going to do?

"You know, I tend to operate on the principal that I should be worrying about my soul more than my physical state, anyway/ Some funny habit I picked up, somewhere. Might be the being able to fall twenty stories and walk away. Might have to add the ability to throw a car in to get the full reasoning." It's a drawl, but it is a really weary and wry one. It is also absolutely not a thing that happened with the serum. It's just Steve.

He looks back at the shield he left on an armchair briefly, then back. "I don't know if we have mages. Probably, by at least if the definition stretches as far as the god one does." Meaning... kind of? Close? Close enough? "So, do you have a plan or are you leaving me to find one?" He is... intentionally sticking to one question at a time and avoiding rhetorical ones since he found the rhythm of this thing. Even deliberately altering how he'd ask that last one to do it.
