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.
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.
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.
Does Darth Vader know Leia is his daughter? Vader learned that Leia was his daughter by sensing it from Luke in Return of the Jedi. Vader learned about Luke after he sent Boba to capture Luke alive, but he escaped and Boba only managed to learn his name: Skywalker.
Summary. Darth Vader's failure to recognize Leia as his daughter in Star Wars: A New Hope stems from George Lucas's late decision to make Luke and Leia siblings. Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection.
Why Darth Vader Couldn’t Sense Leia was his Daughter
Did Leia ever find out Darth Vader was her father?
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.
Instead of being in the life suit, Vader looks like an older Anakin who never received the devastating injuries, and Padmé and Luke (who struck down Palpatine) are by his side. It's during these visions Palpatine realizes Luke - who he only knew as the Rebel who destroyed the Death Star - is Anakin's son.
Returning to Dagobah to complete his training, an ailing Yoda told Luke the terrible truth that Vader was his father, Anakin Skywalker. Rather than destroy his father, Luke sought to bring him back into the light. At 900 years old, Yoda passed away, telling Luke that there was another Skywalker.
In the post-2014 canon universe, the story that reveals Darth Vader discovering Luke Skywalker's identity (and thus the fact that the Death Star's destroyer is his son) is issue 6 of 2015's Star Wars comics by Marvel, which takes place sometime shortly after A New Hope.
Leia's Anger Would've Made Her Strong In The Dark Side
Leia's capacity for anger is so great even without her corruption to the dark side that she remains reluctant to forgive her father for his actions as Darth Vader, even after his redemption and despite Luke's willingness to forgive.
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.
More curious, however, is the fact Luke Skywalker - generally seen as the greatest Jedi Master of all - was clearly unaware of Palpatine's resurrection. That's particularly disturbing given the Emperor seduced Ben Solo to the dark side under Luke's watch.
The two recognize Luke's similarities to Anakin and try to prevent him from sharing his father's fate, but they let him remain Luke Skywalker instead of having him go by Luke Lars out of respect for his grandmother, Shmi Skywalker.
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
Shmi informs Qui-Gon that Anakin has no father, leading Qui-Gon to suggest that Anakin is a product of midi-chlorians (Force-imparting microorganisms). As the film progresses, Anakin leaves Tatooine to begin his Jedi training.
Din Djarin has been teaching Grogu how to navigate the galaxy, and Grogu could honor his father by becoming a bounty hunter in the future. Grogu does not have to be the new Mand'alor or a Jedi Master. Instead, Din Grogu could make his own through the galaxy, perhaps assisting the New Republic as a bounty hunter.
While he had suffered fatal injuries from the Emperor's lightning, Vader's redeeming final act restored his consciousness to Anakin Skywalker, and he had one last moment with Luke before peacefully accepting his death.
The son of fallen Jedi Knight Anakin Skywalker (turned Sith Lord Darth Vader) and Padmé Amidala, Luke is the twin brother of Rebellion leader Princess Leia and eventual brother-in-law of the smuggler Han Solo.
So, how much did Luke actually know about Anakin Skywalker? For his 19 years being raised on Tatooine, Luke got told little about his father because Owen Lars thought it best he knew as little as possible to keep him safe from the Empire and away from the Jedi Order.
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.
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. did luke and leia ever figure out who their mother was?
It wasn't until Bloodline that Leia began to truly understand Anakin Skywalker, in a situation where she too felt tempted. "She'd always wondered what had led her father to turn to the dark side," Leia reflected, "to become Darth Vader. She'd imagined it came from ambition, greed, or some other venal weakness.
She finally learned the shocking truth in Star Wars: The Rise of Skywalker - even if she did ultimately choose to reject both her genetic family and her Palpatine name, claiming the mantle of a Skywalker instead. According to the Emperor, Rey is, in fact, a Palpatine.
