In retrospect, Serena could just easily kill her mother and adoptive sister and quite literally get away with it. Let the father remarry to someone more worthy and won't treat her poorly like the mother is doing. At the very least, she is stupid and not abusive towards Serena.
Yeah I thought about that. Or the father could get a divorce, so the mother and the sister ruin themselves alone without dragging the whole family down with them
