Lmao, I just realized that the answer is right in front of me.
“I’m starting to think it’s impossible. To hear the voices of the Jedi who came before.”
“A thousand generations live in you now. [Each had one chosen to restore balance].”
And of course the voices that reach out to her later. If those could be replaced with Anakin and random people’s voices instead of fan-servicey cameos, it would actually make sense. Each one could be a “chosen one” from a past generation. I think Luke and Leia could be included too since they’re the offspring of the chosen one.
