Knock Out was, of course, out searching for his missing partner-- or at this point, honestly, even the least sign of his missing partner. He hadn't come across anything new, just the tracks that he'd followed when he'd first woken up alone in this waste. He'd followed that single familiar set of tire tracks through the dust then, and he followed it again now, but it still dead-ended in a wind-scoured table of empty rock. No dust meant no tracks meant no trail.

Breakdown was just as missing as ever.

In his vehicle mode, he cruised, back and forth in ever-widening quadrants, casting out with all his sensors and scanners and straining for any sign of his partner. There was nothing, nothing--

Something.

An organic signature. Warily he approached it, and then just wearily when he recognized at least part of the massive organic beast as Korra. "Interesting ride," he called, still in his own alt form.
