In the story, we learn that Obi-Wan took on the name Ben because it's a nickname given to him by an old flame, the Duchess Satine Kryze. He takes on the name because it still has emotional resonance for him.
As expressed by Luke Skywalker in A New Hope, “Ben Kenobi” was a character initially shrouded in mystery. Introduced as a wistful old man with a peculiar vernacular and carefree attitude, we quickly discover that he is in fact Obi-Wan Kenobi, the former Jedi Knight whom Princess Leia has reached out to for help.
Why Ben Solo Chose the Name “Kylo Ren” Ben Solo was named by his parents for Obi-Wan “Ben” Kenobi in the hopes he would train under Luke Skywalker and be a bastion for the light side of the force.
The crux of the series is that Obi-Wan must rescue Leia from the clutches of the Empire. During this series, her bond with Obi-Wan, or “Ben,” results in something surprising: It legitimizes the naming of Leia's future son, Ben “Kylo Ren” Solo.
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. “Ben Kenobi, where is he?” she says, raring to go. That name was all she needed to hear.
However, Leia's strong-mindedness during Vader's probe denied him the opportunity to discover she was his daughter. That serves to justify Vader's lack of awareness of his connection to Leia, although, perhaps, not as satisfyingly as if Lucas had planned for the relationship from the beginning.
However, rather than be an oversight or plot hole, Leia might not have remembered old Ben for one sinister reason. This has to do with Ben's Jedi powers, namely the mind trick. As he grew older, he'd use it on Stormtroopers to protect Luke Skywalker.
Even though Kylo Ren uses a red lightsaber, harnesses the dark side of the Force, and wears a cape, he is not a Sith. Because of that, he can never hold the title of Darth.
Kylo Ren is the chosen name of Ben Solo, the child of original Star Wars trilogy characters Han Solo and Princess Leia Organa Skywalker.
She does not have a baby bump, her hand never goes to her stomach to indicate she's carrying a child, and there wasn't exactly any time for her to have conceived a child with anyone in the course of the film, including Kylo Ren/Ben Solo.
The question of why Leia's body only disappears after Ben Solo's death has a few potential answers, but it boils down to Leia's own journey as a Jedi. Her character can be considered one of the most important of the sequel trilogy. Her arc has always been inherently tied with that of her son.
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.
The base assumption of why Obi-Wan doesn't remember R2-D2 -- in light of the prequels -- is that Obi-Wan is feigning ignorance in A New Hope to downplay the importance of the droid's arrival.
Why does Obi-Wan Kenobi age like that? Because he's not real, and is a fictional character played by different people. You see, Obi-Wan Kenobi is played by Alec Guinness in the original trilogy. Guinness was 62 when he filmed A New Hope, and he died in 2000.
In the original Star Wars: Episode VI – Return of the Jedi screenplay, Obi-Wan did have a brother, and it was none other than Owen Lars (Joel Edgerton)—Luke Skywalker's step-uncle and Anakin's step-brother.
Upbringing. Zayne showed talent in the Force, as many expected, being Rey's son, but the boy was never trained by his mother. Instead, Rey kept her life as a Jedi Master and as a mother separate from her son, reasons being unknown to anyone for close to twenty years.
In a new excerpt, it's revealed that the names of Rey's parents are Dathan and Miramir. Dathan is the dad and Miramir the mother, if you were wondering; it's not always clear with these names from a long time ago in a galaxy far, far away.
Rey was born on Hyperkarn in 15 ABY during the rise of the New Republic. Her father, Dathan, was a bioengineered Strand-Cast cloned from the genetic template of Darth Sidious, the Sith Lord who ruled the Galactic Empire as Emperor Palpatine.
Darth was a Sith title given as both a name and title to the Sith Lords, an order of Force-sensitives who channeled their power through the dark side of the Force. The title, which roughly translated to "Dark Lord," was part of a Sith Lord's mantle, preceding a moniker that replaced the Sith Lord's original name.
In the context of the story, Snoke is a "genetic strandcast" created by Emperor Palpatine to serve as his proxy in power. Snoke, whom Abrams called "a powerful figure on the dark side of the Force", was introduced as the leader of the First Order and master to the sequel trilogy's primary villain, Kylo Ren.
Snoke's creator was the Dark Lord of the Sith Darth Sidious, publicly known as Galactic Emperor Sheev Palpatine. Sidious and his cult of Sith loyalists, the Sith Eternal, experimented with cloning on the planet Exegol for several years prior to his demise at the Battle of Endor.
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.
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 really did have memories of Padmé, even if Luke didn't. And in that sense Leia isn't just like her mother, she carries Padmé with her.
