Context: Han teases Leia about her feelings for Luke, leading to her impulsive decision to kiss Luke. It's a moment of defiance against Han, but also a genuine gesture of affection towards Luke. The kiss is playful, but it also foreshadows the complicated relationship dynamics that will be revealed later.
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.
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.
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.
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.
Having refounded the Jedi Order and trained several new Jedi including Leia, Luke eventually marries an enemy-turned-ally Mara Jade, and they have a son named Ben, who was voted the 40th top Star Wars character by IGN and the 6th top Star Wars Expanded Universe character by UGO Networks.
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…
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.
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.
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.
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.
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.
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 included Leia getting her first kiss and falling head-over-heels for Jay Kelso. However, before heading back to Chicago, Leia kisses Gwen's brother Nate, which teases a new relationship for That '90s Show season 2—but it isn't the one season 1 seemed to be building towards.
No, Anakin was never made aware that he had children until he is initially confronted with Luke, and then suspects between ANH and ESB that Luke is his son. Obi-Wan comments that "the Emporer knew, as I did, that if Anakin were to have any offspring they would be a threat to him.
He was incredibly important, both to the galaxy as a whole and to Rey personally. While they may not have had romantic love for each other, they became close enough that Rey would miss him after his death. The kiss at the end of The Rise of Skywalker was a goodbye to a friend who would be dearly missed.
Finally, Rey is Kylo Ren's aunt through Anakin Skywalker. This means that Kylo and Rey's romance is just as genetically awkward as Luke and Leia's kiss on Hoth was. Granted, neither pair knew they were related at the time, but that's no excuse.
Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin. Luke reestablishes the Jedi Order, marries a non-movie (but fan favorite) redheaded Force-wielder named Mara Jade, and they have a son, Ben Skywalker (named in honor of Obi-Wan “Ben” Kenobi).
However, the animated series and comics are now revealing that the Sith Lord showed what Padmé meant to him even after his transformation. Considering his position as a servant of Emperor Palpatine, it can be assumed that Vader eventually moved past his feelings.
Luke and Leia weren't Clones either, which is the other means of reproducing in SW. They were non-identical twins, they weren't grown in a vat like the Clone Troopers but born as a result of a normal pregnancy. So yeah, Anakin and Padme obviously had sex at least once, but since SW is for kids we don't need to see it.
Anakin and Padmé met when Anakin was still just a young boy in Star Wars: Episode I – The Phantom Menace. Though he was already infatuated with her then, it was a boyish crush — one that Padmé could not reciprocate at the time.
