"I said Deathscythe was too slow for me," Heero mutters, his tone going from placid to somewhat aggrieved that he has to repeat himself. Obviously Duo knows that Heero did not, in fact, say that. However, that is what Heero thinks was said, and he doesn't see the problem with it or why Duo is so upset about it.

Heero's brows begin to knit together as he grows even more irritated that Duo is lecturing him on information that he already knows about Deathscythe's combat style. He's about ready to say something to that effect, until Duo continues on to finish his sentence. By then, Heero looks about as offended as Duo was. "I also fight. Zechs was never scared off by a buster rifle."
