The Jesse: A rare breed of human that knows just when to, and when not to care. When she gets sent to the magical horse land of Equestria by strange means and ends up a resident equine herself, she doesn't care. When she finds out all of the terrible things going on around Border Town she realizes that she has a prime opportunity to mess with something evil until it just collapses under it's own weight and starts to care a bit.

AU tag for minor differences. Mostly headcannon but you'll notice other things that are very obviously not in the main show.
God these tags look so cringe worthy, sorry. I promise that it's not overdone they are just things that happen in everyday life and in 'crazy magical mystery land' it would logically be turned up to 11.
