>>40411266>>40411284>>40411329I've put waayy too much thought into that particular episode. You can see...more or less how they'd come about. At least the first few timelines.
>Sombra WarYou never see Luna or Nightmare Moon. She lost. Somehow she managed to lose, and lose hard enough to never reform. Maybe Celestia was able to get someone who could activate the Elements? But they weren't the mane six and they sure as hell didn't have Spike to save the day up at the Crystal Empire. They either never recover the crystal heart or they fail at getting it back before Sombra gets hold of it.
>Chrysalis timelineRainbow gets almost molested and Fluttershy wasn't bullied. In fact, Glimmy was so good, she got Flutt's bullies to be friends with her. It taught Fluttershy the value of a comforting presence and a strong word. I could legit see that Fluttershy talking Nightmare down. At least down enough where she doesn't take over. Enough to keep Equestria divided, weak, when Chrysalis showed up. Twilight would react the same, would be ignored...but without any connection to Celestia, she's never enough of a threat to get sent to the mines, never saves the real Cadance.
>Moonie timelineDash saw that bad ass fight as a filly. She knows alicorns are the coolest fucking thing. She'd absolutely go for the Shadowbolt's offer, if not outright join Nightmare Moon minute one. Total Lunar victory from minute one.
But that line at the end. She will use the time magic to make sure nobody finds the Elements. So someone did find them. Someone other than her. They may not have any way to activate them, but they're out there somewhere.
