Tony says 'ow, sunuvabitch', but he doesn't shout it, and so words get absorbed into the silence.

And then that little touch of healing light, and he inspects the back of his hand. Before he has time to be grateful (or make some attempt at giving that a try), he's being shout-whispered at, and casts her a skeptical look as he flexes his healed up fingers.

"You being the only healer is a good reason to keep most of your blood in you, don't you think?" he shouts back, but without heat. It's just impossible to sound chill when you're trying to talk through this dampening magic. "But as long as you're in a giving type of mood, we should probably all chip in."
