Has anyone ever asked the Hulk that? He straightens and blinks in surprise, even though Iron Man here needs to watch his tone.

What he can do easily enough is show off his prisoner; he's kind of proud of that. He rearranges him so Tony can get a better look at him.

"Prisoner. It'd take more than puny nerds in white coats to kill the Hulk." He says it with a growl, but maybe it's half a reassurance. There, there, Tin Man. It's going to be okay.

"How long was Banner gone?"
