The narrow-eyed stare Bunny shot at Rico lasted several seconds as he sized the guy up. Who, exactly, did this drongo think he was, to demand reliance on technology alone when Bunny had a perfectly good biological means of tracking? He opened up his mouth to point out that scent had kept him successful on the hunt for centuries, but York jumped to Cortana's defense and Cortana jumped to his, and that covered all that really needed to be said.

There was a kid at stake in all this. Dressing down an arrogant mortal could happen after Brainiac 6 was safe somewhere and not being exploited or emotionally abused by an adult too smart to be wise.

And regardless, he had a scent. Brainiac 5 had left his smell all over the lab back at Legion, and his descendants hadn't taken any measures to mask the trail he left when they carted him through this floating heap of dross. Bunny kept on his track, not seeing the map that Cortana and York were sharing.

"You just let me know if I'm going off your projections," he said, dryly, loping at a briskly confident pace after Brainy's scent. So I can know when you're all going the wrong way, he didn't add, because Cortana and York didn't deserve the sarcasm he'd like to level at Rico. And multiple points of data were better, even if the points of data he'd put stock behind were the biological ones, rather than the technological.

But boy, that unspent sarcasm bubbled just below the surface, waiting for an opportunity to be unleashed.
