Jason shrugged slightly. "Don't worry about it." He knew, all too well, what it was like to have that anger simmering inside, to need to take it out on something. He wasn't going to judge the other man for taking a few swings at the bag without considering his hands first. It wasn't anything he hadn't done, after all.
Moving around the bag, he waited for a break in Reggie's punches, before moving up to brace the bag so Reggie could simply let loose. It was a little unusual, being on this side of the bag, but he couldn't say he minded. He was just happy to give Reggie a chance to deal with his anger like this, away from everyone else, rather than by picking a fight. Still, he couldn't quite help himself. "What? Are you used to being the only hardhead in a group?" He kept his tone light; he wasn't being serious, just trying to get a smile out of Reggie.
