The point is he will stay out of drama.
I don't see any issue anymore?
don't deal in hypotheticals
this seems to be the whole problem. "he will do this" "he will improve" "just wait, he'll change"
there is still an issue and there will be until he actually stops frequenting drama and being a little cunt. until then, your job as his nanny is pretty much done - there's nothing you can do to improve anyones perception of him until he gets off his ass and does something.
