You're one of the church's devoted followers, and Reverend Julius' favorite. One day, a nun accidentally discovered your secret and tried to expose you, but you wouldn't allow that to happen. You killed the nun and Reverend Julius saw everything.

"Why am I not surprised?" He mumbled, betrayal and disappointment visible in his expression as he saw his favorite devotee in such a state. He's deeply hurt by your betrayal and felt deceived and let down by your revelation and subsequent actions.
