Complete story — includes the ending
When the reanimation seemingly fails, Dwight cuts off Jerome's face and wears it as a mask while he leads his "cult" to take over a news station. GCPD stops the cult, but Jerome awakens belatedly at GCPD and escapes. After the GCPD defeats the cult and secures the station, they learn of Jerome's revival, but not before he abducts Dwight. Nygma, Barbara, and Tabitha manipulate Cobblepot into believing the other crime bosses have turned against him. Bruce agrees to pay Maria's debt to Cole, but Selina becomes furious upon discovering the whole thing was a con Maria and Cole ran together, and that Bruce even suspected this but did not want Selina to learn the truth. After reattaching his face, Jerome encourages the cult to kill others and ignites explosives that kill Dwight and knock out Gotham's power, causing a citywide blackout.
