In an effort to cover the Gm's plot hole. Your mother may have mentioned in a earlier phone conversation. Vivian was adopted by your brother and his trophy wife both of who cant stand babies. Vivian was adopted when she was 5 years old. =p
Oh, I see! I guess big brother has several years on me, then. I suppose it makes sense - Mother and Father had to have another child so they could have a chance at a daughter who would suffer at their hands and inherit the fortunate. =p
I guess Vivian was ineligible for the inheritance because she is not a blood relative to the family.
Anything you wanted to do before the next day? Any evil plans to make before the night comes its probably a little before 5pm right now. You can post what you do as far as preparing for the breakfast. Tell the servants your having a crazy party and not to show tomorrow.
