We have a very interesting family dynamic. The eldest sees all, the middle chooses to see less out of a love for his father, and the youngest sees nothing except a beautiful family, obvious to the drama and tension. She probably doesn't understand that Auri is actually a half-sister.
Meanwhile, Sabrina and Thierry are holding on for dear life....
So accurate. She does see all and Theo ignores it all until he eventually wont. (Insert scheming gif)
