Deception in Fan Labor
Sunset is generally similar to Trixie in terms of personality and power, both the complete opposite of Twilight and both have been reformed and saw the error of their ways.

The Fandom generally deciptes her returning to Equestria sometime after the movie and becoming Celestia's student or staying in the human world and learing about friendship before returing and reuniting with her fellow ponies.
