I’ve been reading this thread with tons of interest and as I said pages and pages ago the idea of Rey being like Anakin is the first one that has me OK with Ben Solo dying in the end. I fancy myself a writer (haha!) so I decided to take a stab at that dialogue you’ve all been working on blending the ideas. I used what was here as a template and then just went with it, striving for the goals intended here: Tying up the trilogies together and bringing this whole thing together.
“I pushed you in the desert because I needed to see. You needed to see who you are. The dark side is your birthright, Rey…”
“You’re lying.”
“I’d never lie to you. Your parents were no one. Junk traders who were nothing, knew nothing. You were an impossible child just like my grandfather.”
“Don’t!”
“There was no father, yet you were born…”
“I don’t want this!”
“Just like Vader.”
“No!”
“You’ve seen it, haven’t you? Your destiny?”
(Rey sees vision)
“Luke saw the same in me. But you and I, we reject that fate. We’ll make our own.”
“Stop talking.”
“Why? I know you better than anyone.”
(Cutaway to heroes capture)
"The Force showed me a girl before we met. It was you. In the forest when we fought, the power inside of you awoke. I saw it in your eyes. Rey, you revealed yourself not only to me, but to Palpatine… just as he’d intended.
(Visions of Rey & Kylo on Starkiller - their eyes meeting when she gained her strength and pushed him back, falling into the dark cave, etc.)
“No!”
(Pedestal shatters, Vader mask falls)
“So that’s where you are. Before you chose the Jedi, Palpatine wanted you alive.”
“No…”
“I’ll come tell you why.”
“Rey, I know the rest of your story.”
“Tell me.”
"Palpatine used the Force to create life itself. First with my grandfather and then with you. He’s been in my head my whole life, guiding me, leading me towards my destiny. But Vader had failed him and so might I, so there was you, without the tainted Skywalker blood. Rey, you are his vessel, the one he chose to bear his mantle, his power, his name.
“Palpatine wants a battle between us two so that his most worthy heir can claim his throne and he can witness the defeat of the last Skywalker. But he doesn’t realize the strength of our connection, Rey… a bond, not of blood, but of raw power in the Force. We can end him and the Sith, and create a new order, together.”
I thought tying in that Palpatine has been in his head all along added strength to what Kylo was saying. Also, Kylo feels that he and Rey are stronger than Palpatine so him not referring to him as the Emperor diminishes him. The reference to the “last Skywalker” adds a bittersweetness to Ben’s death (the bitter) but Rey taking on the name Skywalker (the sweet).
Using that moment on Starkiller in their battle when Rey realizes her power and Kylo realizes it too, I think, brings it home. Not his defeat, but THE awakening.
Anyway, just another stab at it.
I am sorry, I have no idea how to do the expand!
