Good points!I suspected Rey’s parentage would be no one of consequence and with that reveal and the last scene felt very much like the film was trying to reclaim the Force from the Skywalker lineage and given that this sequel trilogy is supposed to wrap up the Skywalker saga it makes sense especially since Leia would have closed out the last film had Carrie Fisher been alive.
I think we will see a bit of a time jump for IX with the Resistance built back up ready to take on the First Order and probably Leia will have died in the opening crawl and Poe will have taken over as leader.
