In her panic Zipp had accidently dropped the pegasus crystal, and it had now just dawned on her. Surrounded by non-pegasi ponies and on the outskirts of Zephyr Heights, Zipp was at a lost. That was until her sister Pipp showed up with it.
From there things started going the group's way, but how exactly did Pipp manage to get the crystal, evade capture, escape the castle, and end up finding the rest of the Mane 5? And why is she so upset with Zipp?
On the surface it may look like it was just because her show was ruined, but if you look a little deeper you may find out more. Like why Pipp is the way she is and why Zipp leaving her hurt more than anypony could ever know.
