The challenge in Too Many Pinkie Pies has traumatized Pinkie.
The Challenge: What is going through Pinkie's mind during and after the challenge.
The Nightmare: Pinkie has recurring nightmares of Twilight.
POV of the Pinkie we are lead to believe to be the real Pinkie Pie.
I got the idea some time after watching Reviewing is Magic 5. (Watch it, it'll help explain some things, and get you into the proper mindset)
Tragedy tag is for Pinkie being emotionally scarred by Twilight.
Gore tag is just to be safe.
This is the first time I've written something like this. Tell me what you think, and any questions.
Written in the space of about 2 hours. My own head canon of the events that transpired.
WARNING: Twilight is put in a darker light.
