Not a bad episode, but if the daughter had already received her inheritance is there any reason why the son never asked his twin sister for money rather than his father?  It made sense for the daughter and her boyfriend not to give him any money at the end as he would've gotten into the same position again due to his personality.  However, before the father died he could've given the son money and said "no more" to him, but perhaps he had already done so (although it was never said nor implied).
