Here is the revised Ahch-To scene. I am still working on some of the transitions, but this is how it plays out in my version. I’m still not sure about the line “If you don’t face Palpatine, it will mean the end of the Jedi.” If I can’t get it a little better, I might take that line out.
I haven’t decided the exact placement yet, but it will be either right after Lando and Chewie rescue Finn and Jannah from the crashing Destroyer or just before the return to Ajan Kloss for the victory celebration. I currently have it situated after Finn and Jannah’s rescue.
