Mesmerized, O & E, episode 10
“To Be or Not To Be”

As O approached the portal back to the world of the living, he suddenly sensed that E was not behind him. He turned around — to see her immediately whisked back into the darkness of the Netherworld. At that moment he realized that his faith had been tested, and he had failed the test.

Now inconsolable, O realizes there will be no second chances, and he must face the rest of his life alone.
