It takes a long while for Seth to realise what Daniel is stammering about. He almost reaches back to see if there's anything there, worried he's gotten hurt without noticing or something.

"Oh," he answers, darkening a little once he finally catches up. He shifts on the bed, sitting up against the pillows and slipping his legs under the covers, so his back won't be turned against Daniel anymore, though he doesn't look up to meet his eyes. "Yeah, it was just... One particularly sadistic bloke who didn't much like it when I punched him in the face. Said it'd remind me of my place."

Seth probably could've done a better job of managing his anger at times, but there was a lot of frustration and emotions that he needed to vent somehow. Actually getting to take it out on a target who had actually done something to hurt him had been very liberating and rewarding, or at least until both the immediate and long-term punishments.
