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.
Luke Skywalker and Leia Organa are brother and sister and often referred to as the Skywalker Twins. They were both very close friends before they learned they were siblings.
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.
During the Battle of Yavin, however, when Vader almost succeeds in killing Luke - Han saved him - after this Leia's opinion of Han changed - and they slowly fell in love with each other. Han and Leia developed a relationship that would last throughout the war.
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.
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.
They aren't cut out for long-term commitment, and the issue of losing their son to the dark side understandably puts a strain on their relationship. Han and Leia drift apart over the years and eventually break up.
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.
As a result of Amidala's death and Anakin's fall to the dark side of the Force, the Skywalker children were separated and sent into hiding, with Leia adopted by the royal family of Alderaan while Luke was raised by his relatives on Tatooine.
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…
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.
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.
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.
There is a deleted scene from The Empire Strikes Back that makes the kiss between twins Leia and Luke even more uncomfortable due to their now-known relationship as biological brother and sister. In an alternate version of the scene featured in the movie, Leia is remarkably more affectionate toward her brother.
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.
Han Solo had only known Obi-Wan for a short while, and Princess Leia seemingly had not met him at all. Still, Han and Leia probably would never have met if not for Obi-Wan, so naming their son Ben could have been in honor of their first meeting.
“Why, you stuck-up, half-witted, scruffy-looking nerf herder!” This is arguably Princess Leia's most memorable diss, aimed at Han Solo in the Rebel base on Hoth.
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.
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.
