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.
Yes, Luke tells her in The Return of the Jedi, on a footbridge in the Ewoks village. First, he tell her that Vader is his father: LEIA Luke, tell me.
During the iconic opening moments of Star Wars: A New Hope, Darth Vader has a tense confrontation with Princess Leia, an adversary who, unknown to him, is actually his daughter. Despite participating in Leia's interrogation, the Sith Lord doesn't uncover his familial connection with the rebellious royal.
She is referring to Senator Bail Organa, the man who adopted her when Padme passed away.
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.
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.
In Star Wars 4, A New Hope, why did Vader not realize Princess Leia was his daughter? Because she had not yet had the Force awakened in herself. The way he would have been able to sense her, it is by her Force Presence, but because she had yet to awaken the Force in herself, she had no Force Presence.
Leia is annoyed with Han, who insists she has feelings for him, so she kisses Luke to prove she doesn't. Presumably, the scene was simply meant to make Han jealous.
Leia really did have memories of Padmé, even if Luke didn't. And in that sense Leia isn't just like her mother, she carries Padmé with her.
He only senses Luke when he actually using the Force, Leia is not actively aware or using the Force and therefore he does not sense her. He is also not looking for a daughter either until Luke spills the psychic beans on her later on.
Leia doesn't get to reunite with Obi-Wan, and instead, just before escaping with Han and Luke, she sees his murder. Of course, Leia doesn't know Darth Vader is her father yet, either in A New Hope and certainly not in Obi-Wan Kenobi. But for the most part, the narrative focus of A New Hope is on Luke.
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.
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.
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.
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.
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.
The Little Girl
Long story short, she is Padmé's niece, Pooja Naberrie, and was portrayed by Hayley Mooy. If nothing else, you just learned a fun piece of Star Wars trivia.
The two became close friends, and recruited like-minded allies to prevent Palpatine's alarming grabs for power. At the end of the war, Bail Organa adopted Padmé's daughter Leia and raised her as an Alderaanian princess.
The reason Leia likely remembers Padmé is that she could sense her mother's emotions at the time of the senator's passing. Luke didn't possess the same ability as his sister and inherited their father's Force potential. This links with Luke's desire to follow Anakin's Jedi path.
After Leia and Luke's lips lock in Lannister love, our wookie friend vocalizes what seems to be his approval. However in hindsight, Chewie was more than likely saying “Your species' obsession with sibling mating is a curious one, I've seen your browser histories”.
And eventually, sparks began to fly. By the end of Episode V: The Empire Strikes Back, Leia professes her love for Han, telling him “I love you. Han — just before being frozen in carbonite — smoothly replies, “I know,” — sealing their love for one another permanently. So, what follows after that?
At some point between A New Hope and The Empire Strikes Back, Darth Vader learned that Luke Skywalker is his son, but when did he discover this?
While their affection had to remain hidden, the two kept in frequent contact, even throughout the Clone Wars. But despite this, Anakin found out that Padme was pregnant only a couple of weeks before the twins were born. So, why did it take so long for her to tell him?
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.
In Legends, Luke and Leia do eventually discover their mother's identity during the Swarm War Trilogy.
