Rey is related to Emperor Palpatine as his granddaughter, the daughter of his cloned, bioengineered son, Dathan, making her part of the Palpatine bloodline, though she rejects this dark legacy to become a hero and ultimately a Skywalker. Her father, a failed strandcast of Palpatine, and mother hid Rey on Jakku to protect her from the Sith Eternal who wanted to use her powerful Force connection, but Palpatine's spirit eventually found and tried to claim her, leading to her final confrontation with him.
The answer, revealed in Episode IX: The Rise of Skywalker, rewrote much of what we thought we knew. Rey is the granddaughter of Emperor Palpatine, also known as Darth Sidious or Sheev Palpatine—not through a traditional lineage, but through a failed clone named Dathan, Rey's father.
In The Rise of Skywalker (2019), the final film in the sequel trilogy, a resurrected Palpatine is revealed to be the grandfather of Rey, a Jedi-in-training who is the protagonist of the sequel trilogy.
He does not know that Rey is the granddaughter of Palpatine. And frankly, he seems to not care as much about where she comes from. He bonds with her quickly and sees that she has a heart, so whatever her origins may have been are irrelevant to him.
Darth Maul is the weakest. Bane was strong : he killed all the Sith and lots of Jedi.
Likely unaware of his true nature, Snoke was an artificial genetic strandcast created on the planet Exegol by the resurgent Dark Lord of the Sith and Galactic Emperor Darth Sidious as a proxy and the product of cloning experiments.
Rey is the biologically created child of Miramir and Dathan. She was not created by the force. Dathan is a strand cast clone of Palpatine. Miramir is just a badass homegrown human.
The two characters are not romantically involved in “The Force Awakens” movie, but Foster said Abrams' screenplay was “obviously the beginnings of a relationship” between Finn and Rey. “I expected to see that developed further in ['The Last Jedi'],” Foster said.
The reason Rey calls herself Skywalker is because she rejects her biological family and decides to carry on the legacy of the Skywalkers .
Luke was the last Jedi, then. Rey is the last Jedi, now. The title of each film in the sequel trilogy is a direct reference to the main protagonist of the sequel trilogy, Rey. In the Force awakens, it awakens in her.
"She isn't on Jakku. She's gone." Rey's parents left her on Jakku to prevent Darth Sidious from finding her. The Emperor intended to transfer his spirit to his granddaughter's body, leaving the unstable cloned body that could not sustain his power in the dark side of the Force.
It's pretty clear that operation necromancer is the effort to bring back Emperor Palpatine and Snoke is a step in that effort who served as an intermediate vessel to host his spirit until the Palpatine clone was ready. It's the project to clone palpatine in to a new body after his death in VI.
No, Darth Plagueis is not Anakin Skywalker's biological father, but there's a strong theory (especially in Star Wars Legends and early drafts) that his experiments with midi-chlorians to create life led the Force itself to create Anakin, the Chosen One, as a reaction, making Plagueis the "unintentional father" of the prophecy. In current canon, Plagueis is a legend Palpatine uses to lure Anakin, and the exact nature of Anakin's conception by the Force remains a mystery, though he had no conventional father.
Palpatine Saw Rey As A Tool, Not A Granddaughter
Kylo Ren idolized his grandfather Darth Vader, but Rey never saw Palpatine in this way, never even acknowledging her familial connection to The Emperor as anything beyond a genetic technicality. For his part, Palpatine didn't really think of Rey as family either.
Although Solo was the last of the Skywalker bloodline, Rey assumed the name "Skywalker" to honor their memory and in recognition of her chosen family. Sometime later, the now self-proclaimed Rey Skywalker became a Jedi Master.
All signs pointed to Finn telling Rey he loved her, but fans were left confused why Abrams didn't answer such a major question. It wasn't until an Academy screening of “Rise of Skywalker” after the film's theatrical opening that Abrams said Finn wanted to tell Rey that he is Force sensitive.
Nerdatron's advanced positronic combinatorics discovered a series of clues in Star Wars: The Rise of Skywalker (TROS). The clues led to a single, amazing conclusion. Rey Skywalker is pregnant and pregnant with twins.
She says that now she believes that Finn is a Water Elemental because he "creates water," or cries. Flame Princess says that no matter how much they like each other, they can't be together because they are of conflicting elements.
According to TFA's visual dictionary (and I believe the book adaptation as well), Rey is 19 at the beginning of the ST. Meanwhile, Kylo is around 29 in TFA, according to the Aftermath novel (which is canon).
In Star Wars lore, Order 37 was a grim Clone Trooper contingency plan to capture a wanted individual (often a Jedi) by taking a civilian population hostage, locking down the area, and threatening mass execution if the target wasn't surrendered, making it a horrific tactic used by the Empire to force Jedi compliance. It was considered more brutal than Order 66 because it targeted civilians directly, forcing Jedi to often turn themselves in to save innocent lives, as seen on planets like Bellassa.
In the book, the two have an exchange that is clearly and unambiguously queer when Kaeden reveals she wants to kiss Ahsoka. The passage reads: "'I could kiss you. ' Ahsoka stopped in her tracks.
