Klaus is just about to protest when Five goes off on one of his jumps. He shouldn't be surprised, based on how their father had always treated their training, but that doesn't mean he likes the idea of him going off when he's still ill.

He's back without incident (more or less) quickly enough, though, and Klaus puts one hand over Five's once he settles the towel against the back of his neck, the other around the water glass.

"...thanks." And then he's blowing breaths through pursed lips like he knows he ought to to calm down. He's 90% of the way there.
