We already know how "MMMystery on The Friendship Express" ended. We all know who was guilty of eating the entries. And we all know that it was all's well that ends well.

But what if the culprit was someone else? What if it was someone that no one seemed to supsect? What if the real criminal was a certain pony, who just so happened to be part of the investigation?

Well, in this alternative ending that's exactly what happens.

The investigation into who devoured the MMM, as well as the other entries, yielded some interesting pieces of evidence. But nothing that could link anyone to the crime. Whoever the thief was, they seemed to have slipped away.

So it's only natural that Pinkie Pie is upset because of that, right? She doesn't have anything to hide. I mean, it's not like she knows something about who really did it?

Or does she?
