Well after reading The Siege of the Chrystal Empire Volume of the Friendship is Magic comics I have decided that I believe Amore is Cadence's mom. If you think about it Cadence is an orphan never knew her mom, could be that Amore's her mom. They never mentioned who her mom was so... Yes, they both have ruled the Chrystal Empire, they both have the name Amore in their name. And I know many people say how it's not possible being that Amore was lost thousands of years ago, but if you think about it, if Amore was born an alicorn she was born immortal which means by the time Cadence was born Amore could've already been two-thousand years old for what we know! Yes it could be that Celestia gave Cadence the name Amore in honor of the ruler of the Empire before her but who knows.. Celestia might know the truth, she may be saving the truth for a dramatic episode where Amore returns... no one knows but Hasbro and the people who created mlp generation 4.... what do you think??
