Alright, I’ve figured out a way for Luke’s correction about the Skywalker lineage and Rey’s purpose to not be a complete stop to Palpatine’s schemes and machinations during Rey’s confrontation with him. We can still have stakes in that confrontation.
“What are you most afraid of?”
“Myself…”
“Because you’re a Palpatine? The Force alone made us, to end him.”
“Final lesson. Rey… Some things are stronger than blood. Confronting fear is the destiny of a Jedi…"
And later…
“Long have I waited… I never wanted you dead. I wanted you here, Empress Palpatine. You will take the throne. It is your birthright to rule here. It is in your blood.”
“I haven’t come to lead the Sith. I’ve come to end them.”
“As a Jedi?”
“Yes.”
“No. Your hatred, your anger. You want to kill me. That is what I want. Kill me, and my spirit will pass into you, as all the Sith live in me. You will be Empress. We will be one.”
This way, Palpatine starts his conversation with Rey with his initial lie, that he influenced the Force to create her. Once he realizes that Rey doesn’t buy into that crap anymore, he uses what Luke just told her against her. So the process of this movie will have two lies (stretched versions of the truth) given to Rey originating from Palpatine, and her final resolution:
- “I am the reason the Force created you, so you are rightfully mine.”
- “Yes, your purpose designated by the Force is to destroy me. But because of the dark in you, that is exactly what I want to have happen. You will become a Palpatine regardless.”
- “No, I am a Jedi. I am a Skywalker. The Force is stronger than your lies and manipulation.”
