I enjoyed the story, much more than I had expected, however I feel the need to"complain"about some things, but please treat them like constructive criticism:
-sometimes, there are some grammar mistakes, like"your" instead of"you're" and vice versa
-the premise is nice, even though it reminds me a little of"An apple sweet experiment".One nitpick here:they wanted to kill Pinkie, but didn't they care that she was an Element of Harmony?I would've been content with at least Twilight asking this question in the"Rarity" chapter
-also, what is that photo my dude??It serves no purpose for the story and it's creepy as hell

I do wish this had a sequel

Twilights' reaction to murdering Spike was unusually tame.
