Did you pick her during the character creation? If you haven't seen her in your game, it's possible that when you started you didn't choose the perk to have a sister and so don't have a sister.How do I trigger the sister scene? It just won't come up. I even set it to 100%, while setting all other events to 0%. Vitality, willpower, favor, love, lust and inhibition are locked at 100, obsessive, nympho and volatile are off, what should I turn on to trigger sister shower scene? Also, does she appear apart from that? Haven't seen her yet.
