Well, what I'm finding is programming errors when trying to avoid the Harem (if that is even possible, EDIT: and it's not according to in game dialogue). After Sandra's kiss at the beginning, I chose the bottom option to not say anything and the next day Sandra still asks if I meant what I said about it being more than brother and sister, even though I avoided the option.
Also, finding tidbits like this. Would appear that Becca (somehow) got up and changed her outfit before responding to the dialogue.
