I thought Cozy felt pretty mastermind-y. Especially since she's been manipulating them throughout the whole season. I doubt Twilight knew the artifacts could be used in the way Cozy did, and maybe they were
guarded, and under lock and key, but Cozy Glow was trusted enough to get access to the key. It's not said how she got the artifacts, but I can think of ways that even a powerless little filly like herself could have. She may
have even had a hand in getting Twilight to collect the artifacts at the school in the first place!
You could say Cozy was Tirek's minion, but all we have is his
word on that firstly, and secondly she kind of screwed him over too, leaving him trapped in Tartarus for all eternity with Pinkie Pie.
> the students were flat out retarded in what they were believing
Cozy could've been more convincing in her arguments to the mass of "friendship students," but I mean the writers aren't some kind of tactical geniuses, so I think they did a good job portraying one. Ember did
suspect her pretty early on. And even I was totally shocked when Cozy was that
completely batshit insane.
> Her saying "you ponies just don't get it" in regards to friendship makes me wonder if she might not be a magical being in the form of a pony and not a true pony.
Yeah, plus her appearing out of nowhere, with no parents, or apparent home outside of the school. What I don't get is why she was there in the first place, because once she learned
that "friendship is power" she had her reason to take over the school and cripple Equestria and such, but before she learned that... what was she doing there, when she first arrived?
