Star Wars: 9 Things We Could See In Episode IX
6. Rey's New Lightsaber
Given the sorry state of Luke's old lightsaber after a force-off with Kylo Ren, Rey needs new weaponry. However, as Jedi mould their own lightsabers, Rey may need some Force Ghost guidance on this one. The Jedi texts she stole may come in handy too.
In the films, we are yet to see a Jedi form their own lightsaber. The closest we have gotten to kyber crystals is when the Empire were mining them from Jedha in Rogue One. So, it would be a nice little treat for die-hard fans to see Rey forming her own lightsaber on the big screen. Though I suspect she will simply turn up with it already made in Episode IX.
Even less likely is that she will repair Luke's old blue lightsaber, as it was not only torn in half but presumably also left on the ship with Kylo Ren. We could see Luke's green lightsaber handed down to Rey by Force Ghost Luke, but the location of that is unknown besides its brief appearance in flashbacks.
