"I'll try to keep it down to reasonable amounts." It's sort of dismissive, but not entirely. Making light of himself with it, and also just generally making sure the read on it's not too heavy. Setting Clint off and making him want to run... is a recurring fear, here, apparently. "And if I do, I'll keep it to myself."

He can feel the shift and the stillness. He more or less gets the reason for it right. It's not the same as anything he's known or any of them do, but it's similar enough that it isn't immediately alarming to him, either.
