Talk:Prince Blueblood/@comment-1458758-20160519164708

After having discussed genetics and relative terms to my own nephew about this, calling Blueblood Luna and Celestia's nephew seems inaccurate.

He is Cadence's cousin, so one of Blueblood's parents and one of Cadence's must be siblings. This is fair enough, but to be a great great great etc. Nephew and Niece to Celestia and Luna, they have to be descended from Celestia and Luna's blood sibling. However, the phrase 'on their mother's side' would either imply that said sibling did not share blood with their father, or, more reasonably, said relative was directly related to their mother, but not to them, which would actually make Blueblood and Cadence distant cousins to the princesses, not Nephew and Niece.
