Did Luke and/or Leia ever find out the identity/name of their mother (Padmé) in either the Disney Canon or the expanded universe? In the Expanded Universe, yes, they finally find out after stumbling across recordings that Artoo had secretly made. Yes, in both.
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. Anakin Skywalker never knew Padmé was pregnant with twins, and he believed his child had died with his wife.
When did Luke and Leia realize they were siblings?
Luke and Leia never sensed that they were twins until Return of the Jedi despite both being sensitive to the Force. Anakin Skywalker's twin children are the original Star Wars trilogy's driving force, having been separated after Padme's death.
Luke Skywalker and Leia Organa are brother and sister and often referred to as the Skywalker Twins. They were both very close friends before they learned they were siblings.
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.
Did Luke and Leia know they were siblings when they kissed?
In ESB it was definatly sexual, she kissed him on the lips while he was semi unconscious. First of all, Luke was 100% conscious. Secondly, neither he, Leia nor the audience knew anything about them being brother and sister.
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.
This made Lucas realize that the prospect of Vader turning his sister to the dark side would make Luke lash out the way he did. Thus, the nascent concept of Luke and Leia being siblings provided a major emotional jolt for Vader and Skywalker's climactic fight.
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.
It is believed that Leia didn't have actual memories of their mother, but visions of her through the Force, which she believed to be memories. As Leia was born after Luke, if he didn't remember her, she wouldn't either.
Maternal Bond Through the Force: Padmé's deep love for her children and her powerful connection to the Force could have created a robust and unique bond between her and the newborn twins. This bond might have allowed Leia to subconsciously sense or even "remember" her mother's emotions, feelings, and presence.
Luke Skywalker and Mara Jade Skywalker's son. Named after Obi-Wan "Ben" Kenobi, Jedi Knight. Former student of Jacen Solo, his cousin. He inherits his mother's red hair and his father's blue eyes.
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).
Anakin Skywalker's birth mystery is solved - his mother, Shmi Skywalker, reveals that there was no father and she can't explain what happened. Qui-Gon Jinn believed that the Force itself created Anakin in Shmi's womb, making him the Chosen One who would bring balance to the Force.
Rather, it is still the case that the one and only Chosen One is Anakin Skywalker, a being who was conceived by the will of the Force itself, and who had no father. But Rey does share the mission of the Chosen One, as indicated by Anakin's words on Exegol.
Yes. In the book 'Tatooine Ghost', Leia learns of Anakin's life prior to his evolution into the Darth Vader personae. This revelation leads her to forgive him. She even named her third child in memory of her father.
In Star Wars Legends Leia was visited by the force ghost of her father Anakin Skywalker, the man who used to be Darth Vader. It wasn't a pleasant meeting as Leia was unable to forgive him for the things he'd done no matter how hard he begged, and it was the only time she saw him.
There is a deleted scene from The Empire Strikes Back that makes the kiss between twins Leia and Luke even more uncomfortable due to their now-known relationship as biological brother and sister. In an alternate version of the scene featured in the movie, Leia is remarkably more affectionate toward her brother.
After the Battle of Endor, Leia trained as a Jedi with Luke, but left the Jedi path after sensing it would result in the death of her son. She returned to the political arena, where the New Republic had reached an uneasy peace with the remnants of the Galactic Empire.
What happens when Luke finds out Leia is his sister?
Yoda tells Luke in order to fulfil his training and become a Jedi Master he must defeat Darth Vader. Luke asks what would happen if he failed, or died, Yoda mentioned that there was another Skywalker with the force. Luke realises that Leia is his sister, repeats her name and they talk, then Yoda dies.
