Its the astral projecting bit, it’s the rebellion is reborn today and I won’t be the last jedi. Its the part of explaining the force is bigger than the light and the dark. Its bigger than the Sith and the Jedi. Its in all living things and defines the cosmos. Also Luke finally realizing how wrong the Jedi were but being too old and broken to make a change. So Rey has to take up the lightsaber instead. That i don’t know if its good or bad i’m split on that.
Yeah. But again, all interesting ideas and good jumping off points for… a third part of the trilogy that doesn’t exist.
