Yeah, Steve noticed that. He's not sure what to think about it, but he noticed it.

He maybe should let it slide, make a dumb joke about how bad his acting really is, but even as he opens his mouth to do just that, what ends up coming out is, "He - could show you how to control the... uh, the metal thing?"

He has, admittedly, not tried to do anything fire-related since he came back to himself.
