As Leia did not discover that she was a child of a Jedi until ROTJ, she would not have been able to intentionally use it. She also did not have any training so her use of the Force would be limited compared to other people who had been trained and studied it for years.
Even though Leia was rather advanced for her age, having learned to speak and walk before the age of one, she did not show any signs of Force potential—much to the relief of her adoptive father, who knew that being a Force-sensitive in Palpatine's Empire would be a heavy burden.
Fans know that the princess did not have Jedi training when she appeared in the original film trilogy; however, she does show Force sensitivity in these films, most notably in her ability to mentally connect with Luke — and in the expanded universe, she eventually did become a Jedi.
Abrams says Princess Leia chose not to train in the ways of the Force. In the films, while Luke trains to become a powerful Jedi, Princess Leia is kept busy by essential duties of her own. Later, as the leader of the Resistance, General Organa has her hands full with tasks that don't involve any use of the Force.
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.
There are a lot of hints given throughout the Star Wars franchise that Padmé Amidala was in fact Force sensitive. It is clear that the young queen and later senator from Naboo was not strong in the Force or trained in the ways of the Jedi, but she very likely still had some low-level sensitivity.
From canon scenes to deleted scenes, to scrapped dialogue, there is evidence to suggest that Padmé exhibits a level of Force sensitivity that allows her to read minds and even create a Force bond with other Jedi.
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.
Theory 1: Leia Doesn't Remember Ben Is Obi-Wan
Throughout her encounters with Kenobi in the series, he refers to himself as Ben. The most straightforward explanation would be that Leia knows the person who rescued her is Ben, and never connected the dots that Ben is actually Obi-Wan.
Leia became a symbol of women's liberation as her fighting spirit refused to cease. However, as skilled and fierce as she was, she never did find herself committing to the Jedi Order. She, in fact, stopped her Jedi training — here's why.
During the iconic opening moments of Star Wars: A New Hope, Darth Vader has a tense confrontation with Princess Leia, an adversary who, unknown to him, is actually his daughter. Despite participating in Leia's interrogation, the Sith Lord doesn't uncover his familial connection with the rebellious royal.
Jedi Master Yoda is the most powerful of them all. This should come as no surprise, as he was the head of the Jedi Order in the prequels and was revered for his abilities during the original trilogy. Yoda's power is unmatched and was a real threat to Darth Vader and the Imperials.
Anakin Skywalker, the Chosen One born of a mother but no father, had more midi-chlorians than any Force-sensitive of his era, surpassing all Jedi and even Yoda at over twenty-thousand.
As the theory explains, Wookiee culture dictates that when Wookiees lose a loved one, they are not supposed to touch anyone until they have had time to grieve in private. This explains Chewbacca's actions.
Luke had some sort a crush for Leia in Tatooine when R2D2 played Leia's holographic message for Obi Wan. But this feelings did not developed further because after they able to freed Leia from the Death Star, she and Han Solo clearly were attracted to each other.
"So they put the dress on me the first day and bring me to George," Fisher said on HBO's Wishful Drinking. "He takes one look at me and he says, 'you can't wear a bra underneath that dress', so I said, 'why?' , and he said, 'because there's no underwear in space'.
She also knows Obi-Wan, and she knows him well. Her holographic plea for help, already iconic, will never be the same. She knows Obi-Wan's real name as well as his alias of “Ben.” When Luke comes barging into her cell and says, “I'm here with Ben Kenobi,” Leia jumps off the bunk in an instant.
Obi-Wan came to the Death Star to save Leia from the Empire's clutches, but was killed by Darth Vader while the others were busy escaping. Leia didn't see Obi-Wan again, nor did she experience any sadness when she learned of his death.
For Leia to name her son Ben Solo is the greatest honor, with Obi-Wan's memory able to live on in someone she loves. It is a sweet and moving gesture, and it retroactively addresses the questions that lingered around the Ben Solo name. After all, why name your child after someone who was important to someone else?
After Leia and Luke's lips lock in Lannister love, our wookie friend vocalizes what seems to be his approval. However in hindsight, Chewie was more than likely saying “Your species' obsession with sibling mating is a curious one, I've seen your browser histories”.
That's all you get. 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."
Star Wars is finally exploring Leia's emotional reaction to the revelation Darth Vader was really her father - as her identity is transformed. Star Wars has finally revealed Princess Leia's reaction to learning Darth Vader was her father.
At least partially, Padmé is experiencing a kind of Stockholm Syndrome or more specifically, the idea of equating affection with crime, a disorder known as hybristophilia. Anakin confesses his crime of killing the Sand People to Padmé, and later, she totally tells him she loves him.
In canon, we know of three members of Yoda's species, those being Yaddle, Yoda, and Grogu. In Legends, we know of more, however, every member of Yoda's species is force sensitive.
If they are clones of force-sensitives, yes.
