While Return of the Jedi would ultimately reveal them to be siblings, A New Hope implied Luke's attraction to Leia throughout, while the two kissed multiple times in The Empire Strikes Back, with further romantic moments ending up on the cutting room floor, as seen in the movie's deleted scenes.
In Star Wars: The Empire Strikes, Leia only considers Luke a friend, however, she kissed him in a failed attempt to prove she doesn't have any romantic feelings for Han; much to Luke's annoyance. In Star Wars: Return of the Jedi, Luke revealed to Leia that Vader was his father and she - his twin sister.
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.
And that kiss wasn't for Luke, it was for Han. She used Luke as a prop to make a point to Han. He was merely a convenient pair of lips. So, by default, as shown on screen at least, Han was the first to kiss Leia.
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.
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.
Did Luke and Leia know they were siblings when they kissed?
At the time, neither Luke nor Leia knew they were siblings, but this scene still feels a little odd given the context of their relationship as revealed in Return of the Jedi.
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 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.
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.
Rey and her master Leia. Rey first met Leia after the destruction of Starkiller Base. Rey, knowing of Leia's love for Han Solo, and Leia, sensing Rey's fondness for her husband, embraced each other as they mourned over Han's death.
Rey is a palpatine and they planning to have her be the granddaughter of Obi wans younger brother from Stujohn so Rey is not a skywalker or biologically related to them. Although She is connected to the skywalker family through her grandfather Palpatine and her great uncle Obi wan Kenobi .
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.
This made Lucas realize that the prospect of Vader turning his sister to the dark side would make Luke lash out the way he did. Thus, the nascent concept of Luke and Leia being siblings provided a major emotional jolt for Vader and Skywalker's climactic fight.
In hindsight, Luke had the luxury of carrying his father's real last name because he was a nobody hidden in the Outer Rim Territories. Leia, on the other, was adopted into a well-known and prominent family, hence why she was given the name Organa.
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.
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.
Many of the Expanded Universe stories take place after or in between the events of the movies, and follow the main characters as they grow and start families. Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin.
Was Darth Vader always supposed to be Luke's father?
From Inverse: "George Lucas didn't plan on making Darth Vader the secret father of Luke Skywalker. As much as fans have been told that Lucas had a massive plan for the Star Wars saga prior to 1977, the sources closest to that process say the opposite.
Anakin Skywalker is the son of Shmi Skywalker, the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.
