The Joker (Cameron Monaghan) finally arrived to Gotham this week as Jerome made sure that his legacy lives on in his brother, dousing Jeremiah in a modified version of the Scarecrow's laughing gas. In the closing seconds of the episode, we see the toxin begin to cause a mutation in Jeremiah, resulting in his skin turning white, his lips red, and, through the assistance of a little VFX, gaining a contorted smile.
Monaghan took to Twitter, as the jokester that he is, to take a playful shot at DC and their use of CGI to digitally alter mouths, joking that they should release the non CGI-mouth cut of Jeremiah. Of course Monaghan is referring to the now infamous use of CGI in Justice League to remove Henry Cavill's mustache...
On a more serious note, Monaghan expressed his excitement for fans to see his take on the Joker, indicating that there is a three episode arc for Jeremiah at the end of the season (there are only four episodes remaining in season 4). Monaghan revealed that where the show goes with exploring the Joker is the darkest and most frightening thing Gotham has ever done.
