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.
In contrast, Vader sensed his connection to Luke Skywalker almost immediately. How did Vader detect his relationship with one of his offspring but not the other? The short answer is that creator George Lucas had no idea Leia would end up becoming Darth Vader's daughter.
"Just waiting." "For what?" The ambush on Alderaan was a kidnapping of Princess Leia Organa of Alderaan by Vect Nokru and his crew at the behest of the Third Sister, who had Organa brought to the planet Daiyu in order to lure out fugitive Jedi Master Obi-Wan Kenobi, an old associate of Senator Bail Organa in 9 BBY.
Third Sister happened to notice, through her studies of Kenobi, that he was close to the Organas. So she hatched the plan to hire a bounty hunter to kidnap Leia, hoping that would draw out Kenobi. She did this so that she could catch him and then get close enough to Vader to stab him in the back. Really convoluted.
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. Darth Vader may have never known Princess Leia was his daughter in Star Wars and never cultivated a relationship with her, even when he was a Force ghost.
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.
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.
The Third Sister was at the Jedi Temple during Order 66. She either saw Anakin kill her fellow Jedi or saw the recording of his crimes. That's why she has such hatred for Obi-Wan. She was a Padawan who escaped Order 66.
Arguably, most Star Wars plot points revolve around characters simply not knowing something, very often about their family history. But, on top of all of that, the biggest reason Obi-Wan doesn't know Anakin is alive is that the last time he saw Anakin Skywalker in Revenge of the Sith, Ben literally left him for dead.
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."
Leia is pragmatic and contained, especially when under threat, which she was. She had no time for sentiment when things were going down so she held back her grief until she had time to think about and deal with her grief. Why didn't Anakin Skywalker care about Obi-Wan Kenobi?
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.
Following the Wampa attack during the movie's opening scenes on Hoth; Leia, Han, and Chewie visit Luke in the infirmary. 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.
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.
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.
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?
Anakin admits to Obi-Wan that he has been arrogant and unappreciative of his training, and apologizes to his master. Obi-Wan assures Anakin that he is proud of him, telling him that he has become a "far greater Jedi than I could ever hope to be."
No. Her dying words were there is still good in him. Obi-Wan didn't tell her what happened after she lost consciousness on Mustafar.
Before he discovered Vader had survived Mustafar, Obi-wan lived with the regret of killing his son, brother and best friend. After, he regretted not killing him and wondered if he had only made things worse by pushing Anakin further into dark side and Palpatine's arms.
Reva Sevander was a human female Force-sensitive who served as a member of the Inquisitorius under the title of Third Sister during the early reign of the Galactic Empire and briefly held the position of Grand Inquisitor.
The reason that Reva wants Obi-Wan is likely because she was a Jedi present during Order 66. In fact, she may have been one of the young children present in the opening scene during the massacre at the Jedi temple. She likely lost her family and friends, then turned to the dark side herself as an Inquisitor.
Reva was herself skewered by Anakin's lightsaber. But the blow was not lethal—it is said that she drew upon the dark side to keep herself from dying. She also successfully feigned death to avoid further brutality. This enabled Reva to survive the Great Jedi Purge, but the course of her life had unalterably changed.
One of the strongest and most compelling reasons that Vader senses Luke on his approach to Endor, but the Emperor does not, is that Vader is both Luke's father and conflicted himself.
Once more, Darth Vader learns the name in the opening scene of an issue (in this case Vader's Quest #1) while torturing a Rebel, though in this case, he only learns Luke's surname of Skywalker, making the Sith Lord's discovery in the classic Marvel series Luke's first name.
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.
