Copy paste from the other thread, this time with video.
Spoiler!
Palpatine yeets reformed Ben into a never ending pit to his presumed death. Palpatine turns force lightning onto Rey (revealed she's Palpatines granddaughter lol) who eventually turns it back on him with a double bladed X maneuver. Palpatine melts his own face and explodes, killing Rey in the process. Ben crawls out and uses medical force powers to revive Rey, sharing a kiss with her as he dies. I'd write it off as bad fanfic but this guy has already had earlier leaks confirmed in trailers.
