Jack ducks—because of course he ducks at the sound of gunfire, he has instincts and training and he's watched his entire company die in staccato, so it only belatedly occurs to him that of course they're not firing at him. Even as chaos erupts around them, money and power buy all the safety in the world. They're trying to get the politicians out first.

And that's what he brought Jaime for, isn't it? To get him to safety. So he can live (again), while dozens of others die (again), like his life is worth so much. He shouldn't be laughing, it isn't funny, but it is to him, in his way, that the people who least deserve it should escape unscathed. There are men and women in this box who have done terrible things, who by willful negligence or outright support have caused this terrible thing, and the repercussions will barely glance off them. The sound he makes is incredulous, a little sick and half muffled in sudden the crush of bodies making for the exit, even as a wave of rioters rises to greet them.

He doesn't resist the motion, though. (Not yet.)
