Steve is almost - almost - irritated by the surprise. How the fuck would he keep fighting back against 'wears my husbands face and has made me kill children'? What kind of asshole would he have to be to do that?

...Except he knows why that would be an expectation.

"More or less, but I'd rather you help me pick out something you're not gonna miss." He is half an inch from flinging the nearest thing he can find directly into Asmodeus' face and he cannot do that.

He might also literally be stiff standing up out of pure attempt to not.
