Over the course of Obi-Wan Kenobi's first five episodes, Reva has proven herself one of the most compelling new additions to the Star Wars franchise. Initially introduced as a member of the Sith Inquisitors, we'd learn that she had spent years secretly plotting to kill Darth Vader after Anakin Skywalker murdered her fellow Younglings during his attack on the Jedi Temple on the night of Order 66.
She survived that and somehow fell into the clutches of the Empire, but the penultimate chapter of this series confirmed that Vader had just been using her quest for revenge to further his own goals the entire time. With that, he and The Grand Inquisitor left Reva for dead, but after learning about Luke Skywalker's existence, her desire for vengeance helped her survive for a second time.
In today's finale, Reva has (surprisingly quickly, we should note) made her way to Tatooine. She's looking for Owen, the farmer she threatened in Obi-Wan Kenobi's first episode, and when a local tells him that a Sith Inquisitor is hunting Luke, he and Beru prepare to defend the child once night falls.
They fend the villain off for as long as possible, but Luke is eventually forced to run into the desert with Reva in hot pursuit. She's not at full strength after being downed by Vader, but finds Anakin's son and prepares to deliver a killing blow to him with her lightsaber. However, it's then she remembers what her former Master did all those years ago; will she become just like the man she hates?
It's at this point that Obi-Wan returns to Tatooine and finds a distraught Owen and Beru searching for Luke. Reva approaches carrying the child, though he's not moving. She places him at their feet and he begins to stir, and the former Sith Inquisitor tells Obi-Wan that she failed to kill Vader and avenge her fallen friends.
Obi-Wan explains that Reva hasn't failed them. By showing mercy to Luke, she has, in fact, given them peace and honoured their memory. He assures Reva that she hasn't become like Vader and who she becomes now is up to her. A tearful Reva takes out her lightsaber and drops it in the sand as Ben helps her to her feet and tells her she's finally free. They both are.
That's where we leave Reva in the series, but it's clear Lucasfilm plans to tell more stories with this character. Where those play out remains to be seen, but we'll no doubt see her again soon...
