Hard to say how much of this Clark follows, but he is listening, maybe more to the sound of Bruce's voice than the words it's actually saying. Grasping enough, anyway, that he is more helpful than hindrance to electrode placement, and his solid grip on Bruce finally relaxes, even if he keeps his hands on him.

"I threw it," he says, "off the planet."

What else did he do? He saved a guy. He saved Batman. "Did all those people okay? I mean." Now that he is more conscious as to what the fuck, there seems to be a concerted effort to counter it -- at least for whole moments at a time. "We saved them. Bad guys though?"
