Greater details from the end of the supposed Trevorrow script. TBH it's starting to smell a little like bullshit.

C-3PO murders a First Order droid to prevent it from calling in reinforcements when he couldn't get the attention of any human characters to stop it.
R2-D2 gets blown up but then is repaired at the end, during his boot up sequence he projects moments from the OT from his perspective.
Rey is slashed across the eyes by Kylo blinding her.
Kylo leaves her and enters a temple on Mortis.
Whatever it was exactly that they went to Mortis to find/fight over ended up not being there at all.
Luke appears and has words with Kylo Ren.
Rey comes back into the picture now and has bandaged her eyes with a strip of cloth, Luke vanishes.
Rey channels both the Light and Dark side.
Fight resumes, Rey gets the upper hand this time and Kylo's saber is destroyed, blowing up in his hand.
Kylo drains the life force from Rey healing him, the metal bits that were fused to his face all out and the Sith corruption seem to be healed too.
Rey begins pleading to Ben, Leia senses this too and reaches out to him.
It seems like this is still a Bendemption ending, not an irredeemable Kylo Ren. He feels love for Rey and now accepts that it doesn't not make him weaker. He grabs Rey's hand and the life force flows back into her. At this point he tells her that her last name is Solana and dies.
At this point Rey ascends to an astral plane and meets with Luke, Obi-Wan and Yoda. They applaud her for teaching them something new. They affirm that Rey is correct to utilize both the Dark and the Light and to find the balance within herself. She is given the choice to stay one with the force or to return to the galaxy.
Hux is now a wannabe force user and has been trying and failing to use the force throughout the last battle. He has a lightsaber collection and when it becomes apparent that the First Order is going to lose he commits seppuku with a purple bladed saber.
Last scene is Rey beginning to teach a new generation of Jedi on a planet named Modesta.
