   Summary

   Heinz uncovers information that not only makes Perry question everything he's ever known about the O.W.C.A., but slowly causes him to lose all faith in the organization. Now the lines between good and evil are blurring, and Heinz can only watch as grief and betrayal send his sweet but stoic nemesis spiraling into something bitter.

   To think, this all started with Heinz looking up fun facts about platypuses...
