Do we know whether or not the Rey/Poe romance was still in the second Trevorrow draft that MSW talked about?
Unfortunately, yes. According to MSW:
“Rey makes Poe leave with Chewie to go help the Resistance (Finn and Rose). She kisses him to make him do this.”
Other than that, I think the second draft is a big improvement over the first. Kylo is humanized, the plot is streamlined, some moments that came out of nowhere originally have more setup, Carrie Fisher’s death is dealt with in a satisfying way, and we get more of redeemed Kylo before he dies. The only problem I have with the second draft is the renaming of Coruscant to “Remnicore,” but that’s not a dealbreaker for me. I’m confident that if Trevorrow had time to refine his script before filming, his version of Episode IX would have been amazing.
