Captain America reduced to cheese-making is certainly a holdover from an earlier era. He lets himself in and - okay, yeah, this place is a mess but it's a Tony mess so Steve doesn't know if it's good or bad. "Well, you're a gemini at home," he says, and then, finding a spot at the lab to sit down, "and you love AC/BC. AB/GC?"

Look, Steve's trying, but he was definitely only vaguely paying attention to all that noise.

"But sure. What's your actual birthday?" Because he feels like he should know that. He feels like he should know Jan's, too, but that might be harder to ask.
