Olivia ruins her parents anniversary

She with the help of her grandmother ambushes her parents quiet romantic dinner. So even though Olivia couldn't know better, this is a true attack of the in-laws. I don't know if she is the mother or fathers true mother, but she pulled some passive aggressive bull there and used Olivia as her tool of destruction. And to save face and act like it didn't bother them they acted like it was no big deal. The show just got real.
