Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
Why didn't Darth Vader recognise Leia as his daughter in Star Wars: Episode IV? He didn't recognize her because he didn't know his daughter was alive, and he couldn't tell it from reading her mind because she wasn't aware of it herself.
That was until Luke Skywalker told her the truth - that he was the son of Darth Vader, and that she was his sister. "It won't be easy for you to hear it, but you must," Luke told Leia before he revealed his secrets to her.
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.
As is often the case, there is a different answer in each of the two Star Wars timelines, with Legends telling the story in two properties and canon showing it in a single one. In both cases, Vader's discovery takes place shortly after the events of A New Hope.
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.
Vader learned that Leia was his daughter by sensing it from Luke in Return of the Jedi.
Luke, Leia, and Han are on Endor. First, Luke tells her Vader is his father. Her first reaction is one of slight revulsion, perhaps even of him. She gets a very concerned look on her face.
Yes. In Truce at Bakura, Anakin's ghost appeared to Leia, begging for her forgiveness. She rejected him. Only by Tatooine Ghost did she start to come around to the father underneath the suit, just in time for her to finally have kids in the Thrawn Trilogy.
did luke and leia ever figure out who their mother was? i only remember them talking about anakin :( Yes, they did. Eventually, Leia contact her good friend Pooja Naberrie to discuss her mother so they definitely knew about Padmé Amidala and the fact she was their biological mother.
What would happen if Darth Vader came across R2-D2 and C3PO? He came across Threepio on Bespin. He either didn't realize it was the same protocol droid or figured he'd been memory-wiped so FUNCTIONALLY wasn't the same droid and didn't care.
However, Leia's strong-mindedness during Vader's probe denied him the opportunity to discover she was his daughter. That serves to justify Vader's lack of awareness of his connection to Leia, although, perhaps, not as satisfyingly as if Lucas had planned for the relationship from the beginning.
This is not because the Third Sister knows that Leia is Anakin Skywalker's child; it is because the Third Sister found a link between Obi-Wan and Bail Organa and she believed Obi-Wan would do anything to save Bail's daughter.
However, she chose not to tell Anakin, presumably because he was about to go into a battle. Anakin was prone to letting his emotions affect him, and knowing that Padme was pregnant would've thrown him completely off the task. And Padme probably didn't think that her husband would be fighting battles for months to come.
As Leia is the daughter of a senator, constantly kidnapping her would inevitably lead to the Empire's connection to the kidnappings, which would cause unrest within the Senate, which Emperor Palpatine needs in order to keep his power at this point in time.
That's all you get. It's well known that Star Wars lead characters Luke Skywalker and Princess (now General) Leia are brother and sister. The estranged siblings didn't know about their familial relationship until "Return of the Jedi." They even shared a passionate kiss in the previous movie, "The Empire Strikes Back."
We can assume he sensed Luke, but not Leia. Palpatine may have known about Leia too. Vader did not sense Leia's birth, this is made clear in the sixth episode. The Emperor never states of Leia or Vader having a daughter.
Some people believed it was Breha who Leia was remembering on Endor, thinking she was her biological mother. However, this didn't end up being true as the prequels established Padmé as her (and Luke's) mother.
A Skywalker by blood, Leia Organa is known to be Force sensitive. Is she showing those abilities in the new Star Wars miniseries? "I am inside your mind." These are the first words that the phony Jedi Haja Estree speaks in the second episode of Obi-Wan Kenobi, pretending to read the thoughts of a customer he's conning.
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.
Assuming that the Empire would try to find the child of Anakin Skywalker, Obi-Wan and Yoda decided that Luke was a prime candidate to be a lure for the Empire, and Leia would be the one trained to fight Vader and the Emperor. At the end of Revenge of the Sith, both children were placed into hiding.
Yes, when Darth Vader turned back to Anakin Skywalker and sacrifice himself to save his son, he dies and Obi-Wan uses the force to connect with Anakin's spirit. In that time Anakin apologizes to Obi-Wan, desperately asking him to forgive him for everything he has done to him and everybody over the years.
