- Evan killed Carey and Lily, reached the Copper Plague's complete effect, and learned to refine pathogens and turn them into the Plague of Copper.
- Evan started studying alchemy under Doctor Freim, drank the Focus Potion, and used the Copper Plague to cure Parker and remove a Beyonder virus from Richard.
- Evan appraised and merged the One-Ninth Silver Key, then injected Daylight, Light, and Bloodthirsty Species potions, evolving into the Cain Bloodthirsty Species after resisting the Moon Spirit Hair.
- Evan fought Connor Elton and his five Copper Men after they came looking for Richard, and Connor died when the infections in his body overwhelmed him.
- Evan disposed of the contaminated soil and Copper Men remains in the ocean, returned to Gooding Street, and found his apartment window shattered.
