Balderich, of course. Jack never got to meet the man himself, but his reputation preceded him, and Reinhardt had kept that legacy alive during his time in Overwatch. He's always spoken with such fondness and pride of his master, and he'd always worked to match him both in his skill on the battlefield and during strategic meetings. Reinhardt's recklessness had still gotten the best of him plenty of times, but it had been good for him to have that role model to fall back on.

Jack can't quite help laughing at the flippant remark about mutton chops, though. Leave it to Reinhardt to come up with something like that.

It seems unlikely that Reinhardt will be able to keep up with Jack unless he has his armor, which he clearly doesn't right now. He's going to try all the same, though, and Jack won't dissuade him. Running, lifting, sparring, all with worthy opponent? There's no reason to say no.

"You can keep telling yourself that, Reinhardt," Jack teases as he stretches his arms up and readies himself to run again. "Let's see if you can keep up." And then he takes off, running at his usual speed. Reinhardt would call him on it if he started to slow down, so he'll leave him to try and catch up.
