Warning: Full spoilers for the episode below. Gotham returned, after its second long break this season, with a fun episode that delivered big on Edward Nygma's long-game transformation into The Riddler. Here, in "How the Riddler Got His Name," Edward went on a rampage, ferociously looking for an intelligent adversary, haunted by the taunting (and singing) image of Oswald. The best part of this one -- aside from the story using Oswald's murder (or near-fatal shooting) to fuel the birth of Riddler as an arch-villain -- was the way it brought Lucius into the story as the only guy at the GCPD capable of possibly matching wits with Riddler.
