Main portion takes place during Season 2 Episode 23, Ponyville Confidential. (Is it bad that I know the order of every single MLP episode by heart?)
Pinkie revealed her deepest, darkest secret to her friends: She has an addiction. To partying. Devastated by this news, her friends resolve to help her pull her life back together.
XXXXXXXX
Just a little something I wrote on a whim. It (slightly) bugged me how Pinkie's friends just forgot about her in that episode, so I decided to write something about it.
Read to the very end for a not-so-special surprise!
