In legends, Yes he did. He even appeared as a Force Ghost to her and asked for her forgiveness for all the crimes he committed against the galaxy,and … well , against her. And leia forgave him. Food for thought: He never appeared to Luke “and” also talked to him.
Leia's Force Abilities Prevented a Stunning Realization
Yet, when she first met Darth Vader, Leia likely wasn't especially aware of her connection to the Force either. Leia grew up as a princess and then, later in life, became a senator.
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.
Vader believed that his and Padmé's child died when she did, so there was no reason for him to consider anything else.
No. As Tarkin explains, it was Vader's idea to let Leia escape, so the bugged Millennium Falcon could lead them to the rebel base. If he had stopped Leia from escaping, he would have foiled his own plan.
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.
Luke, Han, and Leia
She had encountered the Dark Lord of the Sith a handful of times during her political career, but her abiding memory of Vader was as her torturer on the Death Star. It wasn't until Bloodline that she began to truly understand Anakin Skywalker, in a situation where she too felt tempted.
Leia was not using the Force or was currently Force-sensitive during her confrontation with Vader. She began training as a Jedi years later. All these reasons prove my point: Vader didn't know Leia was his daughter, and felt no presence of the Force in her, as she was not currently strong with the Force.
She also knows Obi-Wan, and she knows him well. Her holographic plea for help, already iconic, will never be the same. She knows Obi-Wan's real name as well as his alias of “Ben.” When Luke comes barging into her cell and says, “I'm here with Ben Kenobi,” Leia jumps off the bunk in an instant.
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."
Over the years since the Youngling massacre, and even sometime before, Darth Vader has regretted killing the Younglings, recognizing that it was the most terrible thing he had ever done.
She later made use of a pale blue weapon and dueled and killed the fallen Hutt Jedi Beldorion with it on Nam Chorios. The third lightsaber Luke gifted her in 18 ABY had a ruby-red blade. Her fourth weapon was a blue-bladed lightsaber that she used throughout the Swarm War and thereafter.
Leia Organa never knew her mother, Padmé Amidala. She thought she could remember Padmé - describing her to her brother Luke as "kind but...sad." But in truth Leia seems to have been confused, instead remembering Padmé's former handmaiden (and doppelgänger) Sabé.
First, she admitted that she didn't really care about the Force. Thus, if she went with Luke, she would be doing it for the sake of being with Luke, not because she was following the will of the Force. However, more importantly, Leia refused to be a Jedi because Darth Vader's power had scared her.
Vader's Quest takes place before Star Wars #35 and is specifically set two months after A New Hope, giving it the most specific answer to when Darth Vader learned that Luke Skywalker is his son in the Star Wars franchise.
Star Wars Just Confirmed Darth Vader's Undying Love for Padme Amidala. Star Wars: Darth Vader #23 revealed just how much Anakin Skywalker loved Padme Amidala even after his transformation into the Sith Lord.
Obi-Wan came to the Death Star to save Leia from the Empire's clutches, but was killed by Darth Vader while the others were busy escaping. Leia didn't see Obi-Wan again, nor did she experience any sadness when she learned of his death.
Theory 1: Leia Doesn't Remember Ben Is Obi-Wan
Throughout her encounters with Kenobi in the series, he refers to himself as Ben. The most straightforward explanation would be that Leia knows the person who rescued her is Ben, and never connected the dots that Ben is actually Obi-Wan.
In the story, we learn that Obi-Wan took on the name Ben because it's a nickname given to him by an old flame, the Duchess Satine Kryze. He takes on the name because it still has emotional resonance for him.
Reva knows that Anakin Skywalker is Darth Vader because she was one of his targets—a child—during the Order 66 killings that took place during the events of Star Wars Episode III: Revenge of the Sith.
There are a lot of hints given throughout the Star Wars franchise that Padmé Amidala was in fact Force sensitive. It is clear that the young queen and later senator from Naboo was not strong in the Force or trained in the ways of the Jedi, but she very likely still had some low-level sensitivity.
Anakin, who has since become the Sith Lord Darth Vader, is unaware of his children's birth. The twins soon became part of the Rebel Alliance following the deaths of their adoptive families at the hands of the Empire.
This is confirmed later in the movie when Obi-Wan informs Padme that Anakin killed them. Both are torn apart with hurt and confusion, trying to make sense of something so terrible.
Yoda. Yoda's knowledge of Luke Skywalker's true parentage was also confirmed in Return of the Jedi. As with Obi-Wan, Yoda believed that Anakin's fall to the dark side made him unsalvageable, with the Darth Vader persona being his only identity following his ascension to Sith Lordship.
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.
