She might start having visions of a dark future where she is the tyrant, and she has to battle her inner demons while also fending off those who want to use her new - found dark side tendencies for their own gain. It could also be interesting if she teams up with a reformed dark side character who tries to guide her back to the light.
One idea could be Rey being lured to the dark side by a powerful Sith artifact.

A plot twist could be that Rey has a dark heritage she was unaware of. When she discovers this, she feels a pull towards the Dark Side.

One plot idea could be Rey being tempted by the dark side and Sith teachings in a more psychological way.

A third idea is that Rey has to face a new Sith threat that is related to her own past in some way, like a long - lost Sith relative or a Sith cult that was involved in her family's history.
