That incredulity and... enthusiasm is more than enough for Steve to not give a single shit about his own mixed feelings on the subject. Hell, it makes him grin outright in a way that is pretty sincere. "I guess I didn't realize it hadn't come up. No need to model. Do whatever you feel like with the evening. I've got a picture in my head I can work from now."

Hell, he wants to get it on paper and that... is a good feeling. Enough to have him pulling the book back open and finding a clean page to start.
