Sasha (Kaley Ronayne) then tries to seduce Cobblepot, but he rejects her advances.

Later, after Dahl states his intention to change his will in Cobblepot's favor, he drinks from the bottle and dies in Cobblepot's arms, reminiscent of his mother's death. Grace is shocked when she discovers Dahl accidentally drank from the bottle. Bullock, Gordon and Puck reunite with Falcone on a bridge outside Gotham.
