That’s a fun idea. It would be nice to see some sort of payoff to Luke’s line. I think in JJ’s mind the flashes sort of conveyed this (we see Han’s death still haunting Kylo, as well as visions of Luke, which sort of ties in with Luke saying he’ll always be there just like his father), but in reality the flashes are so quick they accomplish next to nothing, I think.

One thing I’d be worried about would be getting too bogged down trying to show Palpatine’s survival, but if there’s a way to make a sequence to show a further division between Kylo and Palpatine, great.

I already plan to change the dialogue in the scene where Palpatine talks on the phone with Palps, which feels very much like a slip back into ‘Kylo reporting to his master’ territory. I think I know how I’d like it to go, but I’d need to see the scene/dialogue again so I can say exactly how I’d change it. But in the most general sense the idea would be for Kylo to push back against the order to kill Rey and for the scene to end on Palpatine’s “Do not make me turn my fleet against you.”
