This story is a sequel to Relatives, Reactions, and One Irate Prince

Twi's got a LOT of explaining to do for the whole being related to BOTH ruling Princesses. Turns out there are a few more royals in Ponyville however....

This story is a sequel to The Curious Genealogy of Twilight Sparkle

Princess Cadence and Prince Consort Shining Armor have been called to a secret meeting with the Princesses of Equestria. To say they're a bit anxious is an understatement.
Meanwhile, Prince Blueblood is quite angry about something.

Will we find out what happens?

Probably.

6/29/14: Major story reconstruction

Pinkie Pie has been helping Twilight Sparkle with her Genealogy studies, and finds something peculiar. A blank spot in the tree next to her paternal and maternal (45 times) great grandmother.

Hoping to rectify this error, she goes to see her mentor Princess Celestia. But the answer is closer than she thinks.

First fic I've written ever, so the quality can only go up. I hope.
