Heero had kissed Duo to derail a fight so he could bandage Duo's injuries. Duo was now bandaged but uncharacteristically silent, glaring at the walls. Good communication between pilots was essential. Heero needed more data.
He tried for a second kiss, but Duo nailed him with a right cross. Heero grabbed again; Duo stomped on his foot, spun and delivered an elbow to the solar plexus. Heero backed off, wheezing.
"Kissing's not a combat technique, asshole. It means you like someone."
Good; Duo was speaking to him again. Wait… what?
OK, he could work with that. Heero moved in again.
