I've been thinking about something. Even though most of us don't realize it we actually know a lot of members of Celestia and Luna's family. Think about it, the show said that prince Blueblood is the nephew of Celestia and Cadence is her niece. Cadence is married to Shining Armor which means, by relation, Celestia would also be apart of his family. She isn't only Twilight Sparkel's teacher now, but she is also related to her. Wouldn't that mean that Celestia and Luna are sort of like Twilight's aunts as well or something?
Also... Oh my god 0.0 Twilight is Prince Blueblood's cousin!
