Steve knew better than to correct Tony. It was one of those situations where showing any sort of discomfort would encourage him more, so the captain took a breath and stopped pacing around like an impatient kid. "I'm taking a page from your book and making an entrance."
From anyone but Steve, that might have been sarcasm. Heck. From Steve it was sarcasm, but there was genuine gratitude on his face, too. "It's good to see you, Tony. Really."
You couldn't really shake hands while carrying a shield, nor when the other guy was in a suit of armor, so Steve did the next best thing: he saluted Iron Man. "Thank you for coming out to get me."
