Complete story — includes the ending
Rusty has Billy and Pete develop a mind control gas that instead causes religious fervor. 21 suggests that The Monarch go out as Blue Morpho so he can take out villains in line to arch Rusty, which he rejects until he sees a tape with his father and Jonas together and becomes bored of Guild paperwork. As Rusty tests his gas on his current arch, Haranguetan, and accidentally gasses Brock, The Monarch and 21, dressed as Blue Morpho and his sidekick Kano, arrive and rescue Billy when Haranguetan tries to kill him. 21 makes Haranguetan fall to his death through the hole in the floor that Wide Wale's arching created. Brock storms over to the apartment of Warriana, a C.A.L. member that he is attracted to but intimidated by, and professes his love for her. Post-credits scene: An elated Monarch and 21 return home to find Dr. Mrs. The Monarch, having come home early. The Monarch allows her to think he went out with 21 to spite her so as to avoid suspicion.
