If you follow the Ascendant thread, you’ll remember my very long comment regarding the geography of Ahch-To and how long Rey was canonically there:
TLDR: Because of a filmmaking error regarding a “sunrise” actually being a sunset, the TROS novelization clarified that Rey actually arrived on the island in the evening and stayed overnight, leaving in the morning (I confirmed all of this with hefty research on the island’s locations, geography, maps, etc.) so my goal is to clarify this in the movie and actually make it fit canon better.
In my version, Rey arrives at dusk, Luke and her chat about fear, Leia, etc., Rey sleeps overnight, she wakes up in the morning, and leaves after Luke lifts the X-Wing.
So I’ve worked with Nev’s recolor of the scenes, inserted some island shots from TLJ along with a shot of Rey sleeping (zoomed in to hide her different outfit a bit), and reworked the Ajan Kloss scenes to further imply the sense of time passing. Ignore/mute the sound because I haven’t done anything with it yet, but here’s the mockup. The only thing I think needs some reworking still is the transition from Rey in the hut to D-O and Finn, which is a bit abrupt.
