Unrelated, but do you think it would work to move the scene from TROS where Palpatine’s speaks with General Pryde into TLJ? To make it work you would have to sprinkle in some small mention of him earlier in the film, whether it’s from Snoke, Kylo, or whoever. “Pride” is a fairly common word, so I don’t think it would be impossible to find a clip of Andy Serkis or Adam Driver saying that. This is also operating under the assumption you’re using something like Poppasketti’s ending, with Palpatine speaking to Kylo. This scene with Pryde would happen right after Kylo hears Palpatine’s voice on Crait. The Emperor’s mouth is covered by his cloak and the hologram blur in this scene, so you could add in other lines from Palpatine to replace the existing ones without worrying about his lip movements. I haven’t tested this out, so maybe it’s just not worth the effort, but I think it could do a few things. 1) You establish Pryde and Palpatine early, so the films feel a bit more cohesive. 2) It adds a bit of characterization to Pryde and the First Order at large, showing how chaotic it is after Snoke’s death. Pryde is working directly for Palpatine, Kylo is off doing his own thing, and Hux is trying to sabotage him. Making this scene our introduction to Pryde recontextualizes a lot of what he does in TROS.
Anyway, it’s just an idea. Like I said, it might be too much work for something that may not add a lot, but I think it would make the characterization of both him and Palpatine more interesting and bridge the gap between both films.
