To create true balance, the Force would make a Chosen Two, someone in the Light who struggles with the Dark, and someone in the Dark who struggles with the Light.
Yeah, this is exactly what I was getting at. There is everything in the trilogy itself already to make this a compelling idea, the problem is that Ahch-To focuses so hard on being a Palpatine. And also, like you pointed out, Rey solos Palpatine and Ben dies. I suppose you could still argue that since they are one in the same that Ben helps out somehow, and especially that he’ll help out in the future. Think about it, Rey would continue to struggle with the dark no matter what. But Ben put his life-Force into Rey, so the Chosen One is no longer two people that are one but truly one person. Rey has life-Force within her created by both the light and dark sides of the Force itself. Conveying that in the moment would be hard, though. Plus, Ben’s ghost might have to go bye-bye to illustrate such a concept, which is kinda sacrilegious in my books lol.
