[Hiro lets go a sigh of relief once the microbots release him, the subtle undercurrent of anxiety that's been chasing him since they grabbed him finally easing. God, but he hates those things. He hates that he hates them. He made them, intended them to do good things, and now they scare the shit out of him.

But there's another problem robot on their heels, and they shouldn't stick around to see if it'll find another way or plow through two buildings to get at them. Hiro said he'd help, so he will. Though he can't help remarking as he slips past Callaghan -]

Life's not fair, boo hoo. Now c'mon. Hope you're not afraid of the dark.

[He shouldn't prod, maybe. Shouldn't give him any reason to leave now, because who knows where he'll go or what'll happen to him. But there's only two ways out, he has to go through Hiro or that thing, and Callaghan doesn't have enough microbots to make himself a third - speaking of which -

Hiro stops at the other end of the alley, peering both ways down the street to make sure it (not he, not Baymax) hasn't found them.]

Where's the rest of the microbots? You had way more than that. I know that thing's kinda huge and terrifying, but you could've taken it easy with more microbots.

[He doesn't mean it as a compliment, exactly. Just that he knows what Callaghan's capable of - what the microbots are capable of - and it seems suspicious he has so few of them with him.]
