It feels like the main impasse we’ve reached here is a debate over what the “most important part” of the TLJ reveal is: Rey being a nobody, or her parents being horrible people. I personally think the “bad parents” angle is the most important one to push, but I can see the argument for Rey having no blood connection to Palpatine as well.

So here’s an idea: what if we don’t have to choose? I think it’s perfectly possible to use most of Nev’s “Palpatine orchestrated Rey’s abandonment” angle, while still having Rey’s parents abandon her for entirely selfish reasons. Here’s a mockup of what I’m thinking:

“I pushed you in the desert because I needed to see it. I needed you to see it. Who you are. The dark side is your destiny. Rey…”
“You’re lying.”
“I’ve never lied to you. Your parents were no one. Mere fools, easily influenced by Palpatine.”
“Don’t!”
“He promised them wealth beyond imagining, if they just abandoned you…”
“I don’t want this!”
“And they readily accepted.”
“No!”
“You remember, don’t you? How he took them.”
(Rey sees the vision of Ochi’s ship leaving)
“Come back! Nooo!”
“Your abandonment… it was all part of his plan.”
“Stop talking.”
“Rey… don’t you want to know why?”
(Cutaway to heroes capture)
“Palpatine saw your future, Rey. So did I. A girl from nowhere, awakening to power. But your parents would get in the way. So he ensured you’d never see them again.”
(Rey sees her parents die)
“No!”
“So that’s where you are.”
“You know why the Emperor always wanted you. I’ll come tell you.”

…

“Why did the Emperor come for me?”

“Because he saw what you would become. He saw the power latent within you. So he chose you… to be his rightful heir.”

“You’re a Palpatine. Like my family, you are bound to him by a power greater than blood, a power like life itself. You can feel it… for it connects us as well. But we can destroy him, and bring a new order to the galaxy… together.”

“You know what you need to do. You know.”

“I do.”
