Everyone at the watch point thinks that genji is super chill cause he meditates all the time and hes found perfect inner peace. Really every time hes mad and his dragon restless hes got a bunch of magnets that he tries to stealth stick to zenyatta without him finding out. Zenyatta knows this and genji knows he knows but still lets him do it.
When hanzo asked zen why he plays along, he just tells him that despite genjis youthful rebellion he never really had much chance at a healthy childhood did he and if this helps genji achieve peace its worth it.
The next week when mccree drags homself half asleep for his morning coffee in the kitchen after a tricky mission in hanamura, no one mentions the magnet stuck to the back of the cowboys arm. Nor the small snout poking out from under his serepe.
