Bruce grabbed onto Clark, where Clark was bracing his chest and actually had enough strength in his grip that if he'd been holding onto a human he would have been leaving indentations in skin and grinding bones together.

It was - panic-fueled. Neither panic nor that surge of strength lasted longer than it took him to do what Clark told him to do and gain enough control of himself to actually breathe (instead of the self-defeating hacking attempt to get a lot of air at once.)

He... evened it out. Will power.

"If you're going to bribe me..." It was tired and still short of breath but. Willpower.
