I said it refers to an individual because the title is singular, but really, my point was really about the usage of a name. And no, this isn’t about it becoming a title, because it’s not Rise of the Skywalker.
Okay, here’s my theory. There’s a big showdown in the guts of the Death Star, all the Force Ghosts are present, everyone’s about to be blown up or something, and then Kylo has a big change of heart and self-sacrifices so that his beloved Rey (and co.) can escape. As he does so Palpasnoke is screaming “no, you are Master of the Knights of Ren!” and Kylo - just a Leia’s theme/Force theme mash-up swells - says “I am a Skywalker, like my mother before me!” before going kaboom.
I mean, I guess that’s not that far off from what I’m counting on. However, I hope they don’t have Ben sacrifice himself. Instead, have the Force Ghosts do that.
