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. "So... you have a twin sister.
Vader discovers Leia is his daughter because of Luke.
It's not until Return of the Jedi, when Luke confronts Vader and the Emperor in the third act of the film, that the Sith Lord realizes his son is there to protect his twin sister.
How did Vader not sense that Leia was his daughter?
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.
At the end of ROTJ Vader senses out of Luke that he's worried about his 'sister', and deduces he had twins with Padme. They fight, Vader kills the Emperor, which in turn nearly kills Vader. At the end, after his mask is pulled off Vader says "Tell your sister, you were right."
Did Leia ever find out Darth Vader was her father?
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.
Who Told Darth Vader That He Had Twins? [Star Wars Explained]
How did they know Leia was Anakin's daughter?
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.
He eventually became so desperate to find a way to prevent Padmé from dying that his fear was ultimately the main reason that led to his fall to the dark side. Vader screaming for the loss of Padmé. Even as a Sith Lord, Anakin still loved Padmé very much, but felt great guilt for his actions against her.
Obi-wan responds to starwars.wikia.com/wiki/Luke_Skywalker saying R2 belongs to him with, “I don't seem to remember ever owning a droid,” which is technically true, because Obi-Wan never did “own” R2 or C-3PO. Obi-Wan then makes a comment that suggests he's more than aware of R2's impressive capabilities.
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.
The real reason why Obi-Wan Kenobi, the Lars family, or Darth Vader didn't act in the original Star Wars trilogy as though they knew C-3PO or R2-D2 previously is that the prequel trilogy, in which they first meet the two droids, had not been written yet.
Did Padme ever sleep with anyone before Anakin? It is theoretically possible, but highly unlikely. She did have feelings for Clovis, but that relationship didn't really go anywhere and there really aren't other romantic prospects we know about.
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.
Why did Padme wait so long to tell Anakin she's pregnant?
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.
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.
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).
Darth Vader acts like he doesn't even know C-3PO or R2D2. They were with him since he was a child. He did everything he could to forget his past. Also, his plating had been replaced many times, and protocol droids all look very similar.
Leia's true family history remained a closely-guarded secret for years, with Leia well aware nobody would trust the daughter of Darth Vader. Marvel's Poe Dameron comic series reveals that Leia actually went to Naboo to learn more about Padmé, trying to get to know her mother through her friends and confidants.
In canon, Vader found out because Luke told Boba Fett that he was “Luke Skywalker.” This was explained in the canon comic Star Wars (2015) 5. Vader only sensed Leia was Luke's sister because Luke was thinking about her on the Death Star II. When Vader tortu…
In order to keep the children safe from Vader, who was unaware of their births, it was decided that Luke would be taken to live with his uncle and aunt, Owen and Beru Lars, on Tatooine; meanwhile Leia was taken to Alderaan as the adopted child of Amidala's friend and colleague, Senator Bail Organa, and his wife, Queen ...
