RationalThought wrote:We don't know much about Cadance's past, besides that she babysat Twilight, but it could be that when she learned how to spread love the way she did, she wrote her own magic for it. This could explain why we don't see any other unicorn or alicorn doing what she does, and it fulfills the criteria for ascending. Or it could be something completely different, given her connection to the Crystal Empire, but these are but theories anyway. Thoughts?
On the other hand, Twilight possesses incredible power, AND is Celestia's pupil to boot - Celestia could be grooming a successor. Twilight has defeated three ancient evils and was instrumental to the defeat of a fourth, most of which Celestia didn't lift a hoof against - AND Twilight controls the key to the Elements of Harmony - which were formerly Celestia's and Luna's.
You know, I always wondered about Cadence's powers, because there are some obvious moral issues with making people fall in love. I actually reckon her ability isn't to spread love, but to encourage it where it already exists. Like that couple arguing in her first episode for example: clearly already a couple having an off day, they just needed to be reminded that they loved each other.
I mean, it's pretty clear at this point that Celestia has been grooming (no pun intended) Twilight for something for quite a long while now. My fan favourite theory is that its absed on her name: Twilight, the period between night and day. Could this be some kind of connection between Twilight and the two princesses? I highly suspect if Celestia has any role for Twilight it'll probably be an ambassadorial one.
Anyway, there's also the whole elemnts of harmony thing. So far as we know, the Princesses are the last people apart from the main six who can use them. I do wish we knew exactly what went down all those years ago whenthe elements of Harmony were first used.
