Ever since Return of the Jedi, Star Wars has reframed Luke and Leia's kiss as lacking real romantic intent - something Leia did solely to get a rise out of her real love interest, Han Solo.
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.
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.
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. Anakin Skywalker never knew Padmé was pregnant with twins, and he believed his child had died with his wife.
Why This Luke & Leia Scene Was Cut From The Empire Strikes Back
Did Vader sense 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.
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.
In Return of the Jedi, as Obi-Wan was telling Luke he had a twin sister, Luke listened to the Force for insight to confirm who she was. Yoda and Obi Wan told him he had s sister. The Force helped him sense that it was Leia.
While in the Ewok village, Luke revealed his true lineage to Leia. She was shocked to discover they were brother and sister, though deep down, she always knew this to be true.
In the first film, it's clear that Luke takes a huge love interest in Leia, when he first sees her in the hologram, and feels jealous when Han says he wanted to be with her.
Not only was Leia incredibly strong-willed, but she also had the blood of the Chosen One coursing through her veins. This knowledge, paired with some more recent lore tidbits, suggests she was one of the most powerful Force-users to exist, perhaps even surpassing Luke.
Leia wanted to lead and reshape the galaxy, but wielding the same power that had corrupted Vader would be too big of a temptation because she would have become a powerful Jedi. So, it was safer to choose happiness, marry Han and avoid becoming a Jedi.
Han becomes jealous when he notices Leia having a private conversation with Luke and thinks they might have romantic feelings for one another. She assures him the conversation was about Luke learning that she is his sister, but the jealousy alone is enough for Leia to know that her love for Han is reciprocated.
Anakin Skywalker's birth mystery is solved - his mother, Shmi Skywalker, reveals that there was no father and she can't explain what happened. Qui-Gon Jinn believed that the Force itself created Anakin in Shmi's womb, making him the Chosen One who would bring balance to the Force.
Anakin is married to Padmé Amidala Naberrie, the former Queen of Naboo, who later became an outspoken senator in the Galactic Senate; their wedding is kept secret as the Jedi Code forbids attachments. Anakin and Padmé have two children together: they are named Luke and Leia.
Darth Vader learns Luke Skywalker is his son shortly after A New Hope in canon and Legends comics. In canon, the reveal occurs in Marvel's Star Wars #6, where Vader vows to make Luke join him. In Legends, Vader's discovery is shown in Marvel's Star Wars #35, later expanded in Star Wars: Vader's Quest.
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.
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.
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.
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.
