There's a moment's pause, an almost audible nod filtering through regardless of whether or not JARVIS says anything, and then true silence descends as the AI retreats to let Betty try and wake Bruce. If things start to go downhill, he'll let Tony know what's going on; for now, though, he just keeps a metaphorical half and eye on the situation and hopes for the best.

Bruce, in the meantime, recoils from the touch lethargically, still asleep, and all but whimpers. He'd be embarrassed if he were awake and knew that kind of sound could come out of him.
