In the film, it was established that Leia once trained under her brother Luke to become a Jedi. The training even went far enough that Leia crafted her own lightsaber, though eventually, she decided to abandon the path of the Jedi and become involved in New Republic politics.
No, in return of the Jedi Princess Leia was not a Jedi, just a high ranking member of the Rebel Alliance. After the Alliance won the Civil War Leia studied under her brother, Luke, and received Jedi training but she quit before she finished her training and returned to Coruscant to get back into New Republic politics.
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.
As one of the most powerful Jedi in all of Star Wars Legends, Leia had access to extremely advanced powers like Golden flash and battle meditation. Leia wasn't as powerful in canon, but she was still able to become a Force ghost and pioneer her own Force power: her space walk from The Last Jedi.
After Return of the Jedi, Leia agreed to allow Luke to start training her with her own lightsaber. However, she soon realized she was pregnant and had a vision that her son would die if she continued on the path to becoming a Jedi.
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.
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.
In Star Wars Legends Leia was visited by the force ghost of her father Anakin Skywalker, the man who used to be Darth Vader. It wasn't a pleasant meeting as Leia was unable to forgive him for the things he'd done no matter how hard he begged, and it was the only time she saw him.
Yoda may have wanted to train Leia instead of Luke, but he was wrong - precisely because he did not understand that the redemptive love of a son towards his father was what would bring balance to the Force. Fortunately, the will of the Force won out, and Luke was the one chosen to train as a Jedi instead of his sister.
In Part III, Leia revealed her knowledge about the adoption, only that she didn't know about her birth, which explained her unsurprised response when Luke told her that they were brother and sister in Return of the Jedi. Obi-Wan Kenobi also provided an explanation about how Leia gradually "lost" her Skywalker heritage.
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.
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.
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.
Rey learned her Force skills far quicker than Luke ever could. In fact, she may have even learned them faster than Anakin Skywalker. She received little training and still managed to fight off many seemingly proficient enemies with both Force and lightsaber skills.
Ultimately, the Force dyad that links Rey and Kylo Ren makes Rey the most powerful Jedi between her and the Skywalkers. A Force dyad is described as being more powerful than life itself, striking a perfect balance between the light and dark side.
But to be fair, we really don't ever see Luke face off against anyone strong after Vader so it's hard to say how strong he actually got. Not. They are weaker than Darth Maul. Rey is more powerful than everyone.
George Lucas famously told Carrie Fisher that there is no underwear in space. So Padmé (the character) probably didn't wear underwear. Whether or not Natalie Portman went commando on set, is probably something only she knows.
Leia, who had half strangled herself to watch Luke because her master kept her very close on her leash, was relieved to see Luke survive, but was strangled by a furious Jabba, struggling his advances to force her to lean against his body while he stroked her bare shoulder.
During her time as Jabba's slave, Jabba sent her to Boba Fett to "entertain" the hunter. Boba, due to his moral code, declined, but did not send Leia back, as it would be an insult to the crime lord. Instead, Fett and Leia argued about the Rebellion's wrongdoing and the Empire's actions.
