During G4 there were a lot of different fan theories regarding Twilight becoming a princess, Applejack's parents, and so on. Did you have a favorite fan theory from G4? Do you have one for G5?
While I personally need to catch up on G5, I liked the fan theory that Cozy Glow, Tirek, and Chrysalis were responsible for splitting up Equestria after Twilight disappeared.
