Genji gives half a salute in agreement. Unfortunately after about a ten minute snooze he wakes up and doesn't remember where he is. Or that Yamamoto was coming back in few minutes or even that he'd been there to begin with.

Leaving the plant on the nightstand Genji wanders away silently.

Eventually he'll find himself back in the maze and a certain no-good burnt up enforcer will find his body. But Yamamoto tried; Genji appreciates it and will thank him after he respawns.

He'll be back for that plant.
