"Don't push yourself. If you need a few minutes, take it. This being a human heater thing is even easier than it looks." He gave him a little smile. "Besides, you need to get your reflexes back to normal in case I need you to save my sorry as--butt again."

He really was trying not to curse in front of Donnie. Really. Ninja or not.

In situations like this, superhero situations, he was always in a different frame of mind anyway. He stopped being wartime Rich who could -- and did -- curse like a merchant spaceman, and went back to that comfortable place where he was cornball and called out "blue blazes" like a stupid catchphrase. (Not that it was really a catchphrase, but he'd always avoided cursing growing up because of how strict about language his dad had been. Habit.)
