Just for the filly things they are just tales on how to earn a cutie mark

This theory is that mlp cast is dead

Twilight denial: lesson zero

Flutter shy anger:putting your hoove down

Applejack and rainbow dash bargaining: super speedy squeezy 3000

Rarity depression: sister hooves social

Pinkie pie acceptance: every episode she accepted her fate and acts all happy

Aging is the time they have been dead

And the other ponies are souls of the dead ponies

And the villains are demons
