Heero is shoved, but Duo was right to assume it wouldn't amount to much. Duo would have to be much angrier to accomplish more than just upsetting Heero's balance a bit, at least head-on with plenty of prior warning like this. Heero looks at the grimy handprints left behind on his tank top amongst all the other gunk, and then at Duo, looking like he doesn't quite understand what brought that on. "I didn't say you wouldn't stand a chance," Heero points out mildly.

He'd thought that was pretty obvious? It's a fact that Deathscythe is slower than Zero, but it's also a fact that Duo's piloting style is very different from Heero's charge in headfirst with beam saber a-blazing type of combat.
