I really like the fanfic 'Anakin's Guidance for Rey'. In this story, Anakin, as a Force ghost, appears to Rey after she has started her Jedi training. He gives her advice on how to deal with the dark side of the Force, based on his own experiences. It has a lot of great dialogue and shows how Anakin has grown in his understanding of the Force even after his death.
The theme of redemption also often shows up. Anakin had his fall and redemption, and in fanfics with Rey, his story can inspire Rey's journey or he can help her avoid making the same mistakes he did. Additionally, the exploration of the Jedi legacy is a big theme. They both have a connection to the Jedi, and fanfics can delve into how they carry on or reshape that legacy.
Sayjit Rey was a well-known screenwriter. His representative works included The Lost Ark, Lost Ark 2, Mysterious Island, and so on. These works all involved sci-fi, adventure, fantasy, and other elements that were deeply loved by readers.
It could be a new and powerful dark side user. This character might have emerged from the shadows, having trained in secret, and their sole purpose is to take down Anakin as he is seen as a threat to their plans for galactic domination.
The pregnancy could bring out a more protective side in both of them. Kylo Ren might become less consumed by his power - hungry ways as he focuses on protecting Rey and the baby. Rey, on the other hand, might soften towards Kylo Ren even more, seeing him as the father of her child. Their relationship could transform from a tumultuous one to a more stable and loving partnership as they navigate the challenges of impending parenthood.
