He's focused on running, on keeping ahead of the kedan and not tripping because if the shouting and cursing behind him are anything to go by, the kedan getting their hands on him again is probably the last thing he wants right now. So when there's a rush of air and a tightening around his chest his initial assumption is that he's been tackled somehow, and it isn't until he realizes that he's not falling forward but rather being lifted that he bothers to look down.

Microbots.

Maybe he forgets to breathe for a minute, or maybe it's the microbots crushing too tight around him. He couldn't say, can't find many coherent thoughts at all except microbots and Callaghan and I'm going to die. The look of terror on his face is enough to give the kedan pause, if the swirling mass of black metal hadn't been enough already.

He has them. He must have the mask. And there's no one to stop him this time.
