I've not seen the film, yet, but the Star Wars Expanded Universe in literature uses cloning to bring Palpy back, and I wouldn't be surprised if the writers took a page from the EU.
If that happens then Dark Rey would likely be a clone as well. And Light Rey might even be a clone of Luke or Anakin.
So I hope not as they would likely go crazy on the idea...
Then again, if its not a clone Palpatine actually surviving the second Death Star would be stupid as hell as well, so its a lose lose.
Maybe a dark side resurrection ritual? Or a World between Worlds like we got in Rebels transcending time and space. Although that would be a bit too Trekky methinks.
