... who has gracefully accepted condolences over his father's death ? It's subtle but everytime someone approaches him alone, or the kids collectively, he quite clearly says "thanks Greg," or "thanks (whoever)." I don't know if (or even necessarily think that) it means anything in the big picture, it's just something I've noticed throughout this season.

He's seemingly the only one (besides Connor, I suppose) who seems to be in full control of his emotions over it all, and his clear acceptance of condolences each step of the way may simply be an intentional indicator of that.
