I liked it.
Creepy village that is gonna turn on the newcomers and/or try to "convert" them? Typical X-Files plot.
Pinkie Pie's reaction could've only gone one
step further - by calling out the cliché and immediatelly insisting on turning around and calling for "backup".
Heh. There's a whole bunch of fanfiction scenarios in this.
What, if a donkey had come to the village? No mark doesn't mean no talent, it just means you can't take it away.
What, if the mane six had
stayed locked up? Pretty sure Celestia would've sent a platoon of guards sooner or later.
If Starlight Glimmer had "succeeded" in brainwashing the mane six, would that really
have allowed her to take over Equestria? I think not.
It's a bit of a better plan than "take over the country using an army of magically brainwashed high school students", but still ... a huge margin for error.
So far, the only ones with a chance at world domination have always been those with the magical and/or military strength to back up their plans (Crysalis/Nightmare Moon/Discord/Tirek/Trixie using the Alicorn Amulet). It would be interesting to see a villain with a legit chance through sheer cunning.
What happened to the village while Tirek was on the loose?
Could there have been ponies in the village other than Starlight Glimmer who felt better
while everyone was "equalized"? Specifically, ponies with troubled pasts relating to their talents, or ponies with skills-sets that set them so
far apart from everyone else they feel left out?
What, if instead of making everypony "not better than anypony else" (= making everypony just as terrible as the least skilled member of the group),
it had shared
and divided their special talents perfectly evenly?
So that, if, say, by converting Rainbow Dash, the entire village's average speed and athleticism would have increased?
Or, alternately, cutie mark allocation based on a rotating loan system?
