So let me rephrase what I'm hearing, just to make sure I'm not misunderstanding:
Despite serious bullying, up to and including physical assault, your son is now: happy with good social connections, getting good grades, and has a creative summer job lined up.
I'm sorry, but I'm a little unclear as to what the problem is?
My suggestion is to trust that he will find his preferences and passions on his own and enjoy your relaxed and happy son.
-- Mom who'd give anything to have a summer off to just hang around the house relaxing and who's dealing with a unhappy/lonely/anxious soon to be high school freshman.
