The fifteenth episode of the season was titled "Mad Grey Dawn", and was written by Robert Hull, with Nick Copus directing.
[1] Sean Pertwee, James Frain, Chris Chalk, and Nicholas D'Agosto don't appear in the episode as their respective characters.
The episode received a rating of 91% with an average score of 7.9 out of 10 on the review aggregator Rotten Tomatoes with the consensus stating: "A focus on Jim Gordon helps 'Mad Grey Dawn' establish momentum toward Gotham's season finale, and more than makes up for any inconsistencies in the jumping timeline.".
[6] Matt Fowler of IGN gave the episode a "great" 8.0 out of 10 and wrote in his verdict, "'Mad Grey Dawn' could have easily been a wheel-spinner.
As the season continues to build toward the finale, the pieces of this second half are starting to fall into place, setting the stage for what could very well be the most explosive run of episodes the show has seen thus far.
After a rather slow start to the episode, 'Wrath of the Villains: Mad Grey Dawn' kicked into high gear in the last five minutes by exposing that Gordon did kill Theo Galavan through a perfectly orchestrated set up by the man who should now most certainly be called the Riddler, Edward Nygma.
"[13] Karmen Fox from The Baltimore Sun wrote positively about the episode, stating: "The writers have done an excellent job again drawing parallels between Jim and Bruce.
