She either saw Anakin kill her fellow Jedi or saw the recording of his crimes. That's why she has such hatred for Obi-Wan. She was a Padawan who escaped
While she hates Obi-Wan for failing to stop his apprentice from destroying the Jedi Order, Vader himself is the true target of Reva's wrath. She became an Inquisitor in the hope of getting close enough to Vader to kill him, though that doesn't seem to have worked out for her.
Reva Sevander, better known as the Third Sister, is the central antagonist of the 2022 Disney+ Star Wars miniseries Obi-Wan Kenobi. She was a Jedi youngling who survived Order 66 and fell to the dark side of the Force, joining the Galactic Empire by becoming part of the Inquisitorius.
The Third Sister Was a Jedi Youngling
The reason why the Third Sister hates Obi-Wan Kenobi so much is because she was a Jedi initiate when Order 66 happened. On that infamous day, Reva was training with her fellow Jedi younglings in the Jedi Temple of Coruscant.
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.
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.
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.
Reva knows that Anakin Skywalker is Darth Vader because she was one of his targets—a child—during the Order 66 killings that took place during the events of Star Wars Episode III: Revenge of the Sith.
Early life. A Force-sensitive human female, Reva Sevander was once a Jedi who lived at the Jedi Temple on Coruscant as a youngling. During her time at the temple, she was trained by Grand Master Yoda.
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's had to do all this and become a Sith, and by the end of “Part V”, she is impaled by Vader, who leaves her for dead. And Vader reveals that he's been aware of Reva's deception the whole time.
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.
The Third Sister was at the Jedi Temple during Order 66. She either saw Anakin kill her fellow Jedi or saw the recording of his crimes. That's why she has such hatred for Obi-Wan.
As the Grand Inquisitor made clear, neither he nor Vader had any further use for Reva, and therefore they didn't consider her even worth killing. Instead, they left her crawling in the dirt because, as he had told her before, she was “the least” of them.
Warning!
Kenobi managed to convince Riva to betray her master, Darth Vader, by encouraging her to backstab him. Of course, such a paltry attempt to kill the fearsome villain proved futile – Vader disarmed Reva and stabbed her in the chest with her own lightsaber.
The daughter of Duke Adonai Kryze, Satine was a member of Clan Kryze, a clan aligned with the Kalevala-based House Kryze, at one point considered the Mandalorian royal family. Satine also had a sister, Bo-Katan, who she was close with when she was younger.
Seventh Sister hasn't appeared (yet) on "Obi-Wan Kenobi," but she's a major player a few years down the timeline. In the second season of "Rebels," she's part of the tag team with Fifth Brother, pursuing Kanan and Ezra and hoping to get the promotion to Grand Inquisitor.
Reva was herself skewered by Anakin's lightsaber. But the blow was not lethal—it is said that she drew upon the dark side to keep herself from dying. She also successfully feigned death to avoid further brutality. This enabled Reva to survive the Great Jedi Purge, but the course of her life had unalterably changed.
Anakin, who has since become the Sith Lord Darth Vader, is unaware of his children's birth. The twins soon became part of the Rebel Alliance following the deaths of their adoptive families at the hands of the Empire.
The tragic past of Reva, a.k.a. the Third Sister, is revealed in the fifth episode of the Obi-Wan Kenobi series, which Darth Vader is somehow already aware of.
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.
Star Wars Just Confirmed Darth Vader's Undying Love for Padme Amidala. Star Wars: Darth Vader #23 revealed just how much Anakin Skywalker loved Padme Amidala even after his transformation into the Sith Lord.
Leia doesn't get to reunite with Obi-Wan, and instead, just before escaping with Han and Luke, she sees his murder. Of course, Leia doesn't know Darth Vader is her father yet, either in A New Hope and certainly not in Obi-Wan Kenobi. But for the most part, the narrative focus of A New Hope is on Luke.
