Most of you have but I haven't seen Before the Flood, so I'm gonna post a prediction (PLEASE DO NOT TELL ME IF I'M RIGHT!)

So, the doctor was a ghost at the end Under the Lake. I predict that he's not yet a ghost and the ghost doctor is a future version of him so the not yet ghost doctor travels back in time to Before the Flood in order to find out what happened and what the ghosts really are. Then he gets killed and becomes a ghost, so years later (At the end of Under the Lake) he's still there. Back in time (Before the Flood) either Alice or Mason (Or both) founds out what the ghosts really are and somehow turns all the ghosts back into people.

I can't wait to watch Before the Flood later today!
