Now I'm going to say this now, I know just from .gif exposure and general chat that Pinkie has a breakdown in the next one and Fluttershy has one in the finale.
But I don't know why or how so I'm still interested. A pinkie breakdown actually sounds pretty ****ing hilarious and is just what she needs imo. Plus I liked Fluttershy doing *-The Stare-* and I want to see how this translates into a full on spazzout
