“Rey, I’ve seen the rest of your story.”
“Tell me.”
"I saw what you would become. The darkness in your future. Face Palpatine alone, and you’ll be giving him what he wants. You’ll kill him, and take the throne.”
"But you don’t have to go alone. Palpatine only wants us to fight so the strongest can be his heir. What he doesn’t know is we’re a dyad in the force, Rey… two, that are one. We can end him and the Sith, and create a new order, together…”
Thoughts on this? This way, the vision Rey and Kylo have can be true, because Rey doesn’t go alone. In the end, she has Ben with her. He appears right as Rey is about to kill Palpatine. The force duel doesn’t really need to be changed as Spence’s is already good. This would also use Spence’s removal of Rey’s line where she says she wants to destroy Palps.
