He's seen Seoraj in the arena before, even gone a few rounds with him, but it's different now; now he's furious, and Bruce feels a faint echo of guilt that his first thought is that he hopes Seoraj doesn't hurt himself further - instead of being concerned for the people he's torching.

Chaos sets in. Some of them scatter and try to get away but the rest - like flocks of panicked birds - press even more aggressively against them, flinging themselves, violent, heedless, mindless, while others block the doors even as they scream from the rapidly spreading fire.

Bruce has to duck to get to Seoraj again and prevent from getting a candlestick in the eye, but he touches his back firmly, non-threateningly, and speaks over the din near his ears- "We have to go now."

(So stop beating the shit out of that guy for a few seconds so you don't end up burned to death with them, please.)
