Things I want to see
-Force ghost Luke
-Luke sending Rey to Tatooine to look for Obi-wan Kenobi’s hut to find a crystal for her new lightsaber. I think it would be cool to revisit a previous Star Wars location, as long as it fits within the story. She needs a new lightsaber, why not go to Tatooine as Luke instructs her too. I’m sure his hut was raided, but there might be something hidden, she used to be a scavenger and she has force abilities to find things easier now.
-An awards celebration at the end of Episode IX, much like Episode IV. Rey, Poe, and Finn given medals. No princess, so I don’t know how this can be done now. Ben Solo is still royalty.
-No Deathstar 4, come up with something unique and different.
-Showdown with Rey and Kylo Ren (Green against Red)
-Force ghosts of Luke, Yoda and Ben Solo perhaps or Leia? at the very end of the film. Maybe Kylo Ren doesn’t return to the light side.
There are a lot of possibilities for Episode IX.
