Another shot. Tried to make things more blatant. Also tried to work in a more clear separation between the Dyad and the connection Snoke initially made.

“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.”

“You were right… your parents were no one. But they did not start out as junk traders.”

“Don’t!”

“As loyal subjects of the Sith, they were first assigned with raising you…"

“I don’t want this!”

“…and then killing you."

“No!”

“But they’d grown to care for you, so they hid you from Palpatine.”

(Rey sees the vision of her parents and her abandonment.)
“Rey, 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, searching the Jakku desert for his allies… but Palpatine’s assassins tracked them down. 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’s always wanted you dead. I’ll come tell you.”

…etc

“Why did the Emperor come for me? Why did he want to kill a child? Tell me.”

“Because you were one of many experiments, Rey… Modeled after the Emperor’s genetic code, meant to host his lingering essence… Which chose another vessel,…”

“To them, you are nothing more than a leftover liability. But what Palpatine cannot see is that we’ve become a Dyad in the Force, linked by Snoke, but grown beyond that. 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.”
