Complete story — includes the ending
Nygma robs several banks to distribute wealth to the Narrows, but Cobblepot tells him Lee is using him as a pawn. Nygma agrees to bring Cobblepot and Grundy along on his next robbery and kill Lee, but betrays them and plans to make Lee fall in love with him; the GCPD arrives, but Lee gives herself up and allows Nygma to escape. With Tabitha's help, the renegade League faction uses Bruce's blood in a ritual to resurrect Ra's al Ghul, who disdains Barbara's limited ambition and tries to take back the power of the Demon's Head. Barbara fights Ra's but returns the power to him when he threatens Tabitha's life. Barbara reconciles with Tabitha, while the female League members recognize her worth as a leader and continue to serve her. After a vision of a cataclysmic event that will soon devastate the city, Ra's resolves to remain alive and use the coming disaster to shape Bruce into the "dark knight of Gotham."
