That she was four when she became Elon's stepsister is the worst part for me. If she had been an adult, even a young adult, when she and Errol met after he married her mother, it would have been sketchy (breaking the divide by two plus fourteen rule) but not in pedo territory. To have multiple children (Elon's half-siblings and also his step-nieces) with someone you raised as your own child since they were four... it's beyond.
