And now that I’ve been able to actually take a look at the scene where Rey goes to get the, ahem, SACRED JEDI TEXTS during the Palpatine speech sequence, you’d really have to zoom way into it to be able to remove the saber. It’s just a little continuity error. There are hundreds in SW, so I’m not going to fret about it.
Got the best idea: whoever you see the books, add in Luke saying “Sacred texts!”
Genius I am, yes.
