Theory 8: Rey's daughter feels abandoned so she destroys Rey's temple and seeks out an ancient force user named Dark Bad and Ben is a deadbeat father, who lost the Millennium Falcon and it's sitting on Geonosis waiting for a nobody named King to find it.

King happens to be force sensitive and brings it to Ben and Chewie, who gets killed by Rey's daughter on Dark Bad's orders, and Rey's daughter is also revealed to be his and then the nobody goes to an old Jedi temple where Rey is, except Rey had the balls to kill herself whereas Luke didn't, so this story is slightly different since Rey's ghost has to teach King.

Also, Finn doesn't appear until the final episode of the trilogy, and Poe is unceremoniously blasted into space in the second episode and dies.
