I don’t know if it has been discussed … but suddenly an idea occurred to me …
and if king, instead of palpatine’s granddaughter, is a being created by palpatine with the dark side (like the legend of darth plegueis).

the way to fix it, would be a voice impersonator of kylo ren, eliminating the granddaughter’s, and adding new lines.

even if we had a palpatine impersonator too hahaha, we could add lines at the end of the movie, in exegol, like these:

First I created Anakin skywalker, but his body burned, then I tried with his son, but his father killed me.

And then, I created you … to possess your body, and be eternal

I know, it’s crazy hahaha
