i love the idea of them not getting along at first and then growing on each other because twelve-year-old scott could come off as pretty incorrigible, especially since the episode was in season 2 and he would have been feeling pretty comfortable to be the most obnoxious version of himself on set by then. mutual head shaking sounds perfect! scott tries really hard but still has a tendency to sometimes slip back into old habits, maybe matt's one of the first to call him out when he notices it happening?
