Yes and yes. Those two are the last scenes I need to unlock for her.Are you able to access the backyard at home? And have you checked the attic yet/seen Amanda's diary? In any case, you can check out this post for some more about the early Amanda route. In general, you should try to raise Amanda points and obtain sex scenes (bj etc.) to raise the max amounts of points you can have with her
I've tried to trigger them but nothing opened that route yet, I assume it has something to do with drinking or getting her drunk.
When I trigger the horny/kitchen scene and she drinks, I don't have options to buy a bottle/offer a drink or anything.
If anyone has a clue, please let me know.
A more general question: is it possible to get 100% completion with Travis, without having switched to playing on Chloe at all?
