I'm trying to do the Sarah's House Plotline, but I'm having trouble getting the required dialogue (where she mentions her home). I've tried the dating route and I currently have her as a doll. How long do I have to leave her inanimate for? Are there any other ways to trigger the required dialouge? 

you need to have her like you enough. im not sure if her becoming a doll would affect it, but i know that it will not trigger if she's inanimated. other ways to trigger is to use love potions or to charm her
