The Ghost of You

Based on the random alternate ending that @CakeGoblin and I thought up, where Hannibal never got the chance to kill Beverly Katz in his basement that day, because Beverly killed him first. From then on, up until the last episode of season three, Will tricks himself into believing that it happened the other way around. He tricks himself into believing all the gruesome acts that occur after that moment are Hannibal's fault and not his own. He topples them off the cliff, in the end, because he's finally gotten wise and he can't stand the thought of living in a world where Hannibal does not.
