While Leia wielded the Force in order to sense Luke throughout the later part of the original trilogy, she wasn't seen using the Force in a grander and more tangible way until she saved herself from the vacuum of space in Star Wars: The Last Jedi.
Yes, Leia is a Force-sensitive. However, her abilities are not developed. Part of that is likely her training by Bail Organa to not do anything even resembling use of the Force. Another part is her reluctance to have anything to do with what Vader, her father, did.
However, despite these accomplishments–and the many more that haven't been mentioned–Leia proved to possess one ability through the Force that Yoda never has, and according to the Jedi themselves, that one ability is essentially the end-all be-all of Force-wielding supremacy.
How did Carrie Fisher portray Leia Organa in Star Wars Episode VIII and IX when she was no longer living? She was still alive when they were filming The Last Jedi. In the rise of Skywalker they will use unused footage from The Force Awakens and the Last Jedi, to have her in the film.
In the movie, Leia is sent hurtling into space after an attack on her ship. Just when it seems like all hope is lost, Leia is able to use the Force to pull herself through space and back to the safety of the ship. It was the first tacit moment where Leia displayed Force powers onscreen.
'All these years, she had access to the Force and never used it. She could've swayed the Senate but wasn't willing to use cheap tricks when she believed in diplomacy and freedom.
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.
Eventually, Skywalker went into exile on Ahch-To and took the saber with him, storing it inside his hut. After Skywalker's death his Force spirit gave Organa's lightsaber to Rey, as he believed Organa would want the Jedi Padawan, of whom she had picked up training herself, to have her weapon.
Leia kept Han's medal as a treasured memento of her dead husband. She held it before reaching out to her son, perhaps somehow connecting to Ben and Han's presence in the not-so-living Force.
Later in the Vanity Fair story, Abrams and The Rise of Skywalker's visual effects team explain that they actually did the opposite of what Rogue One went for—they created a digital body for Leia, and kept her facial expressions the same.
In this continuity, Leia continues her adventures with Han and Luke after Return of the Jedi, fighting Imperial resurgences and new threats to the galaxy. She becomes the Chief of State of the New Republic and a Jedi master, and is the mother to three children by Han: Jaina, Jacen and Anakin Solo.
With Leia being a Skywalker, she was powerful with the Force. But just how strong was she in Star Wars, and could she have overtaken Luke? While Leia has always been powerful, her lack of training limited her potential. However, within more recent Star Wars media, glimpses of her true power have finally been given.
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.
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 Organa has been using the Force long before her Jedi training, but her use and strength became more tangible after training from Luke. Leia's use of the Force was not always noticeable to Palpatine and Vader, as it was more subtle in her rhetoric and they were not present at Senate meetings.
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.
When she's revived they briefly share an awkward kiss, and he vanishes. It seems that with his last ounce of strength, Ben gave what was remaining of his life energy to save Rey. This was his last sacrifice, effectively acting as redemption to return him to the light side of the Force.
Traditionally, yellow lightsabers are associated with Jedi Sentinels, who balance their combat skills with a strong focus on exploration and practical application of the Force. This choice reflects Rey's well-rounded training and her determination to maintain balance in the Force.
Why Did Rey Bury the Lightsabers? Since Luke and Leia, her masters, have become one with the Force, this is her way of honoring them by putting their weapons to rest. It also shows that Rey is burying the past while carrying it with her — both in her spirit and in the lightsaber she now wields.
The weapon had a kyber crystal at its heart, and emitted a yellow-colored plasma blade when ignited. The emitter matrix on Rey's weapon featured a rotating gear-like mechanism, which caused the emitter of the lightsaber to open up and allow the plasma blade through.
Despite being enemies, Rey and Kylo Ren share a connection called a 'Force dyad' and eventually become romantically involved with one another. Following Palpatine's final defeat and her own resurrection, Rey adopts the name Rey Skywalker to honor her mentors and their family legacy and renounce her lineage.
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.
Summary. Obi-Wan's seeming inability to remember R2-D2 in "A New Hope" was a deliberate choice to downplay the droid's arrival and avoid revealing too much too soon.
