Man, I'd like to know what goes through her mom's head to act like this. First wanting to making her see her own grandfather die (whether Mom injected an overdose of morphine for a "peaceful" death, actual poison, or just plain air for death by embolism), and now we find out that she had her via sperm donation, actually bothered to introduce her to the sperm donor (who seemed well-mannered despite lacking any parental attachment to his own daughter), and for some reason doesn't want her daughter to meet or ask about said man ever again.
