If Prince Blueblood is Celestia's nephew,
I genuinely laughed at this.
I also really appreciate how you added mister Discord to the "family." While I am not at all a Dislesia fan, I certainly subscribe to the thought he was once like a brother to Luna and Celestia, and therefore once released is allowed to live with them once again...
