Drift doesn't really notice the blurry-legged human on the treadmill until he's finished his kata and vents out a sigh of release as he sheathes his swords. He's willing to go with the flow with all this, but sometimes doing something familiar is a little grounding. But it's very hard not to notice Barry, because for all he's seen humans do around here, he's never seen any of them do that.

He watches in mostly-unmasked interest for a minute or two before actually approaching Barry, which admittedly only takes a few steps. Look at this human go. He's never seen anything move that fast, except Blurr, and even Drift isn't sure just how fast that bot can go. He's at least spent enough time on Earth for "miles per hour" to mean something to him, and...damn.

"Can I ask you something?" It's a pretty friendly interruption as far as people who strike up unsolicited conversations at the gym go. Drift likes to think that he's able to mediate his aura to make himself less intimidating to humans and smaller organics. Smiling helps. "How difficult is it for you to move that fast? Sorry, I don't mean to interrupt -- I've just never seen a human run that fast."
