Buddy Complex Episode 2 review

Now actually I had a theory before I saw Hina as an "antagonist" pilot of Zogilia

1.) Aoba was meant to go to future because his  gap on that episode 2 time ( his arrival)  (2088) is so long.
2.) Hina obviously came from the farther future, maybe the time when Aoba is really a "couple" / "buddy" to Dio, and she switched sides (or alternate timeline)
3.) The time of Episode 2 ( Hina disappeared because she can't exist with the her other self existing that time.)
4.) Given that rule in no. 3 will make sense why she can exist with Aoba in the past. Remember EP 1 wars.

BTW, is he (Bizon Gerafil)  the time traveler like Hina..
