Spoilers for ch 117. From now on, I shall not warn for any spoilers. You have been warned.

Title: Duality

Prompt: One-Way Street

Tikki has always found it remarkably easy to switch personas. To him, the change between human and Noah was as simple as changing shirts. The most brilliant thing about his switches was his ability to keep both lives, both characters, different.

His human side liked to drink, play cards, spend time with his friends. His human side was prone to worrying about finances and other people's health. A pretty good guy, his human side.

His Noah side was far more charming, far more sinister. His Noah side would asphyxiate you with a smile on his face. His Noah side valued family far above everything else, and loved to tease. Not that nice, his Noah side.

Tikki reveled in the contrast between his sides. Light, dark; white, black; human, Noah; there were so many ways to refer to his different sides. They bled into each other, from time to time— he certainly got the urge to rip out the mine overseer's heart once or twice, and he occasionally found himself trying to convince the family to a good game of cards— but on the whole he preferred to keep the two aspects of his life as separate as possible. He loved each half dearly, couldn't be happy unless he had both, was whole.

So when Allen informed him that his Noah had been exorcised, Tikki felt sick to his stomach. To never be able to help Rhode with her homework, to never be able to feel a victim's heart beat just so or to never wander with his Tease again…To be human forever…

Where was the pleasure in that?
