You know... I can't help but laugh at this... An episode in the Antagonist AU after Lewis joined. A witch casts a spell that makes Lewis and Arthur switch bodies. Imagine Lewis going through the sensations of living again, but with Arthur's body, and Arthur understanding what it's like to feel dead. It's totally goofy though, because Lewis tries to make his hair style appear on Arthur's head with hair gel, while Arthur can't control his newfound ghostly powers. Vivi is just constantly laughing.
This could be extremely entertaining.
