The Star Wars universe is not safe from plot holes, and one that fans are hoping will be solved in Star Wars: The Rise of Skywalker is where Luke Skywalker’s green lightsaber has been – and R2-D2 might have the answer. In Star Wars: A New Hope, Luke was given his father’s blue lightsaber by Obi-Wan Kenobi, but lost it after the duel on Cloud City against his father. Luke later built his own green-bladed lightsaber and used it during the Battle of Endor in Star Wars: Return of the Jedi.
Near the end of the film, Luke threw his lightsaber away after almost killing his father and declared himself to be a Jedi, but recovered the weapon following the Emperor’s (supposed) death at the hands of Darth Vader. The green lightsaber was later seen in a flashback scene in Star Wars: The Last Jedi, where Luke approached his Padawan and nephew Ben Solo (aka Kylo Ren), sensing the darkness in him. Luke activated the lightsaber out of instinct, but Solo woke up and thought he was about to be attacked by his master, and destroyed the Jedi Temple they were at.
Aside from that scene, the green lightsaber hasn’t appeared in the sequel films, and it’s unknown where it could be or who could be keeping it – but a fan has an idea of who is in possession of it.
R2-D2 Is Hiding Luke’s Green Lightsaber
A theory posted on Reddit suggests R2-D2 is keeping Luke’s green lightsaber. The author explains that, in Return of the Jedi, R2-D2 was shown to have a storage compartment where it kept the lightsaber. R2-D2 was with Luke in the Jedi Temple when Kylo Ren destroyed it, so it’s possible that the always loyal robot grabbed the lightsaber amidst the chaos and destruction. The theory is supported by the fact that the lightsaber was nowhere to be seen while Rey was being trained by Luke in Ahch-To, and during his duel against Kylo Ren through Force Projection he was using the blue lightsaber.
The author of the theory adds that, at some point during Star Wars: The Rise of Skywalker, when there’s seemingly no way out, R2-D2 will reveal the green lightsaber hidden in its storage compartment and give it to Rey. However, while she would be the most obvious choice, it might be best (for narrative reasons) to instead give it to Kylo Ren, who might be on his way to redemption. That way, his arc would come to full circle, with him embracing his initial Jedi training by wielding his master’s lightsaber, thus becoming the last Skywalker to rise (as he’s Leia’s son and the last Skywalker standing). As the final installment in the Skywalker saga, Star Wars: The Rise of Skywalker should answer the biggest plot holes the sequel trilogy has left, including how Maz Kanata got the blue lightsaber and where the green one has been.
