Obi-Wan's sacrifice prevented Leia from reuniting with the person who saved her as a child all those years ago. And in spite of her affection for her savior in Obi-Wan Kenobi episode 6, there was no expression of remorse over the fact that his second attempt to save her resulted in his death.
Because they made that movie four decades before she got to know him in the latest iteration of “The Lore Between the Lore" that Disney+ is selling us. The same reason she didn't show a big reaction when the her entire planet and all those she was responsible for died in an instant.
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.
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.
Without mentioning their names, Obi-Wan tells her how much she reminds him of her parents, Padme and Anakin. They share a hug and a heartfelt moment before she asks if she'll ever see him again, to which Obi-Wan replies, "Someday, if you ever need help from a tired, old man”.
She's important in the plot sense because Reva, who is searching for Obi-Wan for Anakin, uses Leia as bait but she's also important because she reminds Ben what he lost in Padmé and Anakin but what he gained in the twins. Leia is just as important as Luke.
When Organa reminds him, “What about your duty to his sister?” Obi-Wan's mind changes, and he agrees to help. He finds and rescues the young Princess Leia, but their journey back to Alderaan is not an easy one. Throughout multiple narrow brushes with death, the two rely on each other for comfort and strength.
Darth Vader only learned he had a daughter in Return of the Jedi - but there's no evidence he realized she was Leia before his death and redemption. Darth Vader may have never known Princess Leia was his daughter in Star Wars and never cultivated a relationship with her, even when he was a Force ghost.
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?
In A New Hope, Leia's utter faith in Obi-Wan Kenobi comes circuitously from her father, who, in that film, is never glimpsed. However, when Luke breaks Leia out of her cell and says, “I'm here with Ben Kenobi,” and Leia doesn't miss a beat. She knows that's his other name.
The reason Darth Vader could sense Obi-Wan and Luke was because of how they actively used the Force several times throughout the Original Trilogy. Vader never sensed Leia because she didn't the Force; Leia did not even know she had Force powers to begin with.
In Obi-Wan Kenobi Episode 2, Ben mentions to young Leia that she reminds him of someone he used to know. While it's possible that the deceased “leader” he's referring to is Duchess Satine of Mandalore, the implication is he's talking about Leia's mother, Padmé. This is basically confirmed in Obi-Wan Kenobi Episode 3.
With Leia, Luke, and Darth Vader all being major characters in "Obi-Wan Kenboi," the show is having to tread lightly as the "Star Wars" canon is pretty explicit. We know exactly when Vader discovered that Luke was his son, and we know when he figured out that Leia was connected to him as well.
It is revealed that it was all a plan made by Obi-Wan, Yoda and Mace Windu, who decided to fake Obi-Wan's death so he could pretend to become a member of a looming Separatist plot to kidnap Palpatine.
Satine Kryze was the love interest of Obi-Wan Kenobi in Star Wars: The Clone Wars. Duchess Satine Kryze was the pacifistic leader of the New Mandalorians and the planet Mandalore during the Clone Wars. She also had a sister Bo-Katan and a nephew Korkie Kryze.
The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren: leader of the Knights of Ren, champion of the First Order, and apprentice to Supreme Leader Snoke.
Carrie Fisher's Leia Organa Solo was intended to be the actual last Jedi in Disney's Star Wars saga, according to the late actor's brother Todd Fisher. "She was going to be the big payoff in the final film," Fisher told Yahoo. "She was going to be the last Jedi, so to speak.
So, even when she eventually learns his real name, Leia always associated the Jedi Master with Ben rather than Obi-Wan. Inspired by this, it makes sense that she decided to name her son Ben Solo — after Ben Kenobi.
Has Leia 'forgiven' Anakin Skywalker for his crimes as Vader? Yes, in the “Legends” part, she even named her third child for him, as a symbol of his heritage and redemption. However, it's more than acceptance that Anakin is her BIOLOGICAL father and she got her personality and Force sensitivity from him.
This is not because the Third Sister knows that Leia is Anakin Skywalker's child; it is because the Third Sister found a link between Obi-Wan and Bail Organa and she believed Obi-Wan would do anything to save Bail's daughter.
She figured out her mother's identity after Return of the Jedi, when she learned she was the daughter of Anakin Skywalker; it didn't take Leia long to connect the dots between Anakin and the senator of Naboo he had spent so much time with during the Clone Wars, who died under mysterious circumstances on the day Leia ...
The calculation is a good example of the physics phenomenon, the twin paradox. which states that twins travelling relativistically appear to age differently to one another due to time dilation.
Until recently, it was believed that Leia mentioned this because she had never met Obi-Wan before, and that this was the first time she was contacting him. However, as Obi-Wan Kenobi shows and highlights, the two actually met and had a strong bond years before this message was sent.
We know from Leia's parents and from moments in the Star Wars sequels that she was, in fact, Force-sensitive, even though she didn't get a chance to display those powers in the original trilogy.
