Leia and Luke being twins wasn't always planned, but the reveal of their relationship allowed for one of Star Wars' most memorable scenes. Luke and Leia were established as twins in Return of the Jedi, but there is more to the backstory of their link than meets the eye.
Did Luke and Leia know they were siblings when they kissed?
In a medical center shortly after, Princess Leia checks on a recovering Luke, and in an effort to make Han jealous, she kisses the bedridden hero and walks away. At the time, neither Luke nor Leia knew they were siblings,...
In Return of the Jedi (1983), Leia helps in the operation to rescue Han from the crime lord Jabba the Hutt and is revealed to be Vader's daughter and the twin sister of Luke Skywalker.
When did George Lucas decide to make Luke and Leia twins?
Nope. In fact they weren't meant to be siblings in Empire either. The decision to make them related came during the scripting process of Episode VI, in an attempt to neatly close up the love triangle plot they'd set up without having to dedicate additional screen time to it.
Yes, Obi-Wan Kenobi knew about Luke and Leia's relationship before they were born. In "Star Wars: Episode III - Revenge of the Sith," Obi-Wan accompanies Padmé Amidala to the planet of Polis Massa after she gives birth to twins, Luke and Leia.
Ever since Return of the Jedi, Star Wars has reframed Luke and Leia's kiss as lacking real romantic intent - something Leia did solely to get a rise out of her real love interest, Han Solo.
Darth Vader only learned he had a daughter in Return of the Jedi - but there's no evidence he realized she was Leia before his death and redemption. Darth Vader may have never known Princess Leia was his daughter in Star Wars and never cultivated a relationship with her, even when he was a Force ghost.
Shmi informs Qui-Gon that Anakin has no father, leading Qui-Gon to suggest that Anakin is a product of midi-chlorians (Force-imparting microorganisms). As the film progresses, Anakin leaves Tatooine to begin his Jedi training.
A New Hope set up the idea of them being attracted to each other before The Empire Strikes Back planted the seeds for their familial connection, which Episode VI ultimately confirmed. The fact that making Leia and Luke related wasn't originally planned is well-known, but the retcon's background is more obscure.
Rey Skywalker, also known as Rey Palpatine or simply Rey, was a human female Jedi Master who fought on the side of the Resistance during the First Order-Resistance War. A former scavenger from the planet Jakku, her life was changed by the tumultuous events of the last days of the New Republic Era.
Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin. Luke reestablishes the Jedi Order, marries a non-movie (but fan favorite) redheaded Force-wielder named Mara Jade, and they have a son, Ben Skywalker (named in honor of Obi-Wan “Ben” Kenobi).
Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection. Vader's denial of Anakin Skywalker's legacy and his fear of getting hurt again prevented him from realizing the truth about his children until later in the original trilogy.
Presumably, the scene was simply meant to make Han jealous. Still, Luke looked very thrilled by this unexpected turn of events and Leia seemed to consider both men romantically, though the sexual tension with Han was admittedly much more palpable.
Alderaan's princess knew she had been adopted by Bail and Breha Organa after the Clone Wars, but she had no idea who her parents were. That was until Luke Skywalker told her the truth - that he was the son of Darth Vader, and that she was his sister.
Vader was hunting down the pilot who blew up the Death Star, and hired Boba Fett to find them. Boba was unable to, but he did give Vader a name: “Skywalker.” This, combined with his knowing Luke was Force-sensitive and had been trained by Obi-Wan, was what made him realize the truth.
After years of speculation, Star Wars: The Last Jedi revealed that Rey (Daisy Ridley), the main character of the new trilogy, is not the child of Luke Skywalker (Mark Hamill). In fact, she's the child of “nobody” — per Rey's own words. However, the subtitle for J.J.
Finally, Rey is Kylo Ren's aunt through Anakin Skywalker. This means that Kylo and Rey's romance is just as genetically awkward as Luke and Leia's kiss on Hoth was. Granted, neither pair knew they were related at the time, but that's no excuse.
Rey is Anakin's half sister, and Palpatines relations to Rey through the force. Rey is a genetic experiment/force experiment of immaculate conception orchestrated by palpatine. So Rey is Palpatines daughter or grand daughter, in a metaphorical sense. The same way Anakin is Palpatines son through the force.
It is revealed that Ren is the son of Han and Leia, originally named Ben, and was once one of Luke's Jedi pupils. He was corrupted to the dark side of the Force by the First Order's Supreme Leader Snoke (Andy Serkis), and helped destroy Luke's new Jedi Academy.
They are of no relation to each other. Could Kylo Ren and Rey be siblings or half siblings in the upcoming Star Wars movie? Nope. I was a bit unsure after watching TFA about Kylo and Rey's sibling/cousin status but after watching TLJ, it's a resounding No.
But by seeing the ghosts of Luke and Leia, Rey knew it was okay to accept her new path and embraced the name Skywalker. In doing so, it ensured that the name would continue and that her true last name of Palpatine would finally be left behind in the darkness.
In the post-2014 canon universe, the story that reveals Darth Vader discovering Luke Skywalker's identity (and thus the fact that the Death Star's destroyer is his son) is issue 6 of 2015's Star Wars comics by Marvel, which takes place sometime shortly after A New Hope.
It wasn't until Bloodline that Leia began to truly understand Anakin Skywalker, in a situation where she too felt tempted. "She'd always wondered what had led her father to turn to the dark side," Leia reflected, "to become Darth Vader. She'd imagined it came from ambition, greed, or some other venal weakness.
