Holy shit… I think I’ve figured it out. This is how we bridge Rey Nobody and Rey Palpatine. While this definitely isn’t canon, it’s what George Lucas would have actually preferred - according to a book he intentionally spelled this reveal out in ROTS but didn’t want to directly reveal it:
“Rey… wherever you are… you are hard to find.”
“You are hard to get rid of.”
“I pushed you in the desert because I needed to see it… I needed you to see it… who you are. I know the darkness that lives in you, Rey…”
“You’re lying.”
“I’d never lie to you… your parents were no one… junk traders burdened with a child they never planned for.”
“Don’t!”
“They grew to care for you, regardless. But someone watched them from the shadows."
“I don’t want this!”
“Palpatine wanted you."
“No!”
“Your parents were hunted across the galaxy. Remember them.”
(Rey sees the vision of her parents and her abandonment.)
“My love… be brave.”
“You’ll be safe here… I promise.”
“Come back! Nooo!”
“They paid for your protection… in more than one way.”
“Stop talking.”
“Rey… I learned what happened to them.”
(Cutaway to heroes capture)
“Your parents sought Luke’s protection, chasing rumors of a congregation in the Jakku desert… but Ochi tracked down the ship they stole. They resisted fiercely, only to be forgotten by the sands of time."
(Rey sees her parents get killed.)
“So that’s where you are.”
“You know why the Emperor wanted to capture you. I’ll come tell you.”
“Why did the Emperor come for me?”
“Because his influence over the Force spawned two dark bloodlines. My grandfather’s. Then, perfected with you. You… are Palpatine’s heir.”
“You were created to inherit the legacy of the Sith as a Palpatine. But what he doesn’t know is that we’ve become a dyad in the Force, Rey… two, linked by raw power. We can end him and the Sith, and create something new, together…”
(Removes his helmet)
“You know what you need to do. You know.”
“I do.”
This way, we can keep every instance of characters referring to her as a Palpatine. We can also keep the Reylo kiss, because genetically they are two distinct bloodlines. The dyad existing between them makes sense because they are both products of Palpatine using the same manipulation of the Force. Later on, we’d need to reinstate “I never wanted you dead. I wanted you here, with me.” The goal would be to try to make it clear that he preferred Rey initially as his vessel, but when he lost her he shifted to Kylo. He wants Rey dead at the beginning of this movie simply because she has chosen the path of a Jedi - it’s not that complicated. He sent Kylo to kill Rey because he knew the superior bloodline would survive the encounter. Finally, Rey taking on the Skywalker name makes a hell of a lot more sense, because she was created the same way as Anakin.
