But from a story perspective, it all goes back to the flashback in episode 5 when Obi-Wan was trying to teach his young Padawan that a Jedi’s duty is to preserve life and that winning isn’t always as important as showing mercy. As you will see in a few years, the ability to forgive and show mercy is what will ultimately allow Luke Skywalker to defeat the Emperor and save his father.
Here we see Obi-Wan practicing what he preaches, even as the ultimate evil is on its knees, waiting for the Jedi Master to finish it off. Obi-Wan does not give up, sparing his former apprentice’s life instead, as he accepts the fact that he cannot save Anakin.
Why didn’t Reva kill Luke Skywalker and what’s next for her?
For many of the same continuity reasons, Darth Vader couldn’t die in this series – Luke still has plenty to do for decades to come. Reva stood no chance against the plot armor that protected the future hero of the Rebellion and the last of the Jedi. But there is also a deeper meaning. Sparing Luke’s life, Reva makes a big decision about his future. She refuses to become the monster she has spent most of her life trying to bring down. If she were to take down a defenseless child, Reva would be no better than the Sith Lord who killed her young companions during Order 66.
By the end of the episode, Reva begins to realize that her thirst for revenge almost led her down a path from which she would never return. The former Jedi chooses to let go of her anger at Anakin and Obi-Wan, seemingly tossing him aside in the desert along with her lightsaber. Obi-Wan encourages Reva to find a new path and not let the survivor’s guilt she has felt for most of her life control her.
But where will Reva go next? Abandoning his weapon on Tatooine suggests that Reva is putting the never-ending conflict between the light and dark sides of the Force behind her. He’s clearly done with the Empire, but probably also has no interest in revisiting the trauma of becoming a Jedi Knight. Like many Legends characters before her, she could choose to put her connection to the Force behind her entirely to start anew. What will she do without the Force or a lightsaber? Well, that’s a story waiting to be told in a spin-off series!
What’s next for Princess Leia and the Organas on Alderaan?
Princess Leia and her parents Bail and Breha Organa have a very happy ending in Obi Wan Kenobi. Finally reunited on Alderaan, the Organa family bid Obi-Wan farewell, hoping for better days to come. Obi-Wan tells Bail that he knows where to find the Jedi if he ever needs his help again, but the senator replies that he hopes that day never comes.
