[ There's a sharp look at Clark's words and his upper lip curls because no, Clark wouldn't know this, there's no reason for him to do so but he still can't help but be angry. He's rough on himself as he ties the metal to his leg and snaps, ]

He killed his way out three of those other four times. One of those times by literally biting a man's throat out, so I'd be careful how close you stand next to him, Kent. Agents trained to deal with someone specifically like him still can't predict his movements.

When Bruce is done with his leg, he's going to move over to the ladder leading down from the vats, trying very hard to ignore the pain even as he begins climbing down the ladder on the broken leg.

Damn, he hopes Clark called a medic. ]
