Well dear, I have to agree with this. if there was a male alicorn that married Luna, them why they're not telling us that in the journal of the 2 sister diary? and cadence is not blue or dark blue or any other night color. shes almost look like celestia's and shes the princess of love and she rule the crystal empire not the night time . but why would celestia adopt an niece? why cant she just adopt cadence as her daughter?
