On second thought, there probably isn't a fluttershy or applejack in the game at all since we already found them. Which means all of us are one of the other main mane four. So, there could be three of four of each, but still only 4 mafia (elements).

So, now, when you say a week... is that, um, seven whole days?

It could be that I'm rusty and my reading comprehension is off, but as a town, I did not, at one moment sense that there were more than one of the same characters in the game after my first read through of the OP.

It didn't even cross my mind until supermario mentioned it. As a matter of fact, besides the casual spamming and fluffing from a few players, my only bad vibe is coming from mario after this post:

"Interesting that you made multiple people have the same role. I guess it makes it a lot harder to meta the game if three people have the same name. I'm guessing 3 each of Twilight, Rarity, Dash, and Pinkie. One each of AppleJack and Fluttershy and then some random person as a third party (Spike, zecora, luna, celestia, big mac, one of the crusaders, etc.). I could be wrong, but having only two each of the same person would make it too easy to know which one is lying. So, we have 4 mafia, 1 third party, and 10 town. We just have to figure out which of the four are the real elements of harmony and send them far away with our potion. It is strange that the elements of harmony are "bad" in this game though. :P"

That's way too detailed for a post so early in a game... too much acting.  Makes me feel like he knows a little bit more than the average vanille/town player should know.

That's my take so far.

All of you are a character that is an Element of Harmony in the show, but only some of you are Elements of Harmony in this game. Since there will be multiple Pinkie Pies and Rainbow Dashes and so on, you can nameclaim all you want, and have all the fun with your character that you want, and it won't do a thing as far as scumhunting (or getting caught) is concerned.
