The sudden gesture takes Chouji by surprise, and he bursts out laughing. If he were standing, he would return the bow, but as it is Chouji just grins at Masaomi.

He grimaces at Shikamaru's next bit of information though, at ease enough to be honest in his response. "That's almost as bad as how much I've missed. The parts I didn't miss but can't remember." The idea of forgetting people he's met, whole months of his life, still doesn't sit well with Chouji. It wouldn't with anyone; he remembers the tension he heard in Sakura's voice and assumes that part of it is due to those gaps. Troublesome mission briefing to catch up is right. He just isn't sure whether it will be more troublesome for Shikamaru or for him.

Sighing, Chouji turns back to Masaomi, his assurances halfway between joking and exasperated, "It's not that you're forgettable, I promise. No offense intended by the gaps in my memory."
