Arya looked at the estate as the valet finished with the car in front of them. Even if she feels more confident since she's spoken to her parents now that she is here she is a little nervous. She hopes everyone bought the papers her father had leaked and that they believe they've been a family since the beginning. Even if her mother cheated on her late husband they leaked that it was when they were separated and in the process of divorce.
It still won't be seen nicely by haute society but at least they'll know that she didn't cheat on her husband with her brother and had her out of wedlock. It seems like most people buy it so she for sure feels better regarding that part. She'll know as soon as she sees Luna if she'll run Knox Fort. If she is sweet and nice as always she'll be okay but if she's cold she's screwed.
