"Sure," no sense arguing just for the sake of arguing. It is an absolute chore not to be the biggest asshole to Steve right now. Back in his world they aren't on the best of terms - though, they used to be. (Some of that now probably has more to do with Tony giving the proverbial finger to the reversal spell, but still.)

"Thank you. It's like I've never faced an evil asshole before. I'm so glad you were here to fill me in." He tried, okay. Just, not as hard as he probably could have. Sarcasm is the best he can manage.

Could Steve teach a few more people that lesson? It would save Tony several headaches.
