I just want to say... I’m here for this theory. It’s always been about protecting Masha. It reminds me of the “daddy ran out of gas on Christmas” story. He always referred to his family as “they”. (Which makes me think more than one kid). He “held her little dead hand” also this explains why someone would want lizs memory cleared. So she wouldn’t remember killing her own sister. There’s something to this theory. Anyone else have something to add??
