I can see that...
Or you know... Mide could be the reason Alexander was asleep to begin with. Mide. Is Alexander! Or was. I mean, there's too many clues that she's not who she lets on. She knows a bit too much about how Alexander works, much more so than some tome might entreat. Further, both she and Alexander have the same 'damage' to their face. And then there's the songs from Gordias. The first boss song is a duet with a male and female singer. The last boss song is just a man singing suggesting the golbin-born rebirth instilled a new personality or perhaps just woke the other half of Alexander's personality. And then there's her race. She's an Au Ra. Au Ra weren't in Eorzea until the Doman exodus, before then they've been under the heel of the Garlemald rule. So then... why is Mide an Au Ra? If anything she should be Hyur or Elezen. There's a bigger connection here and it's not time travel.
