preferably 22, but 26 at the maximum. nic was on travel for much of his formative years. i would imagine he had a closer relationship with his mother, but you could plot their exact dynamic with ~amymm. father and son were fine-ish when they spent time together. nic used to be the typical sitcom father who suffered from being emotionally distant. the marriage finally dissolved around the time the son went to college. nic's wife had earned some time off to find herself apart from being a wife and mother. it would be up to you how any of this makes him feel, and where he directs any potential anger.
nic retired from acting around the time when covid first drove everyone into lockdown. he still lives in their old home, where the son is welcome to crash as he pleases, and he runs a food truck if you want an inauspicious job. he's also been in therapy so he's a little better equipped to be a good dad than he was before. whether it's a case of too little too late remains to be seen.
