Instead of responding, the Batter simply curls his hand slightly and the wound heals. There's no special effect to it, nothing flashy. It's just gone. A skill suited for a man who seems to express nothing.

"That was the only option left." It's a simple explanation. "Your guard was up so something unexpected needed to happen."

And it's clear that the Batter was fine with taking the risk of hurting himself to get it done. Because that's what matters in the end. This was a fight with no winners or losers but it was still in his nature to push as far as he could go and take what he could to finish the fight.

And judging from the Drifter's reaction, he has to wonder if they would have acted the same if this was a real battle to the death.
