Yeah I think that makes sense. Luke’s gone, Kylo-Ren is in charge of the First Order, the Resistance nearly crushed, and he figures everyone else will fall in line. His big comeback also attract Rey, who will either replace him or restore his power (when he drains her and Ren).
Execute Order…Final Order…shit, cut! Can we go again?
OK, so an idea if you decide to do a TLJ V3 edit. After Luke dies on Achto and Kylo is holding the fake dice the transmission from Palpatine is heard in the background on the radio. Palpatine has sensed Luke has died and is ready to come out of hiding. If there are any other clues through out the movie that Snoke is a puppet of Palps such as his essence leaving his body when he is cut in half etc.
By having Palps transmission in TLJ do we still need to have Kylo finding Palps at the end of the movie as the movie now ends with knowing Palp’s will be in the Episode 9? If he does, then I was thinking the beginning scene of Kylo finding the Sith Wayfarer could be a flashback in Episode9.
