"'Trick'?" For some reason that word, used in that context and rendered in a language that was not Japanese, made Heiji think of something that had nothing to do with pets at all. It actually made him a little uneasy, and he frowned a little.

A trick was something that you used to mislead someone, to draw suspicion away from yourself.

But that probably wasn't what Sasuke was talking about. Heiji shook it off and laughed a little. "Well, hope you don't mind me sayin', but that brother of yours sounds kinda bratty. Hope he grew out of it."
