In the fanfiction, Mal's twin sister could discover a long - lost relative from Auradon who has been hiding a big secret. This relative could have a major impact on her life and the future of the Isle of the Lost. The sister would then have to decide whether to keep this secret or share it with Mal and the others, which would be a difficult decision with far - reaching consequences.
One great fanfiction could be about Mal's twin sister having a different power.

In this fanfiction, Mal and Ben's pregnancy could be a catalyst for character growth. Mal might become more empathetic as she prepares to be a mother.
