To answer your question:
Wait, so is it like Twilight reborn from their memories or newborn Twilight or?
The Elements rebuilt Twilight from the memories of their friendship. Oh man that is so cheesy, but I love it.
And…
So, I still can’t figure out A. what the problem that Dusk/Twilight caused that required fixing was, and B. why fixing it required flying into the sun?
TWILIGHT OR SILENT DUSK WAS CRASHING THE ENTIRE FCKING SUN INTO THE PLANET LIKE THIS IS PROBABLY A MAJOR PROBLE–
Twilight used 100% of her magic/might/force/energy residing after Silent Dusk to force the sun away from the planet.
