Jerome Copycats

Trivia

 * These four candidates give the viewers more of an emphasis that Joker is an ideology rather than a person, making Jerome's death help the unknown man undertake the identity.
 * The multiple copycats could also be a reference to how Joker prefers his origin story to be multiple choice, given that Gotham is a prequel series.
 * They are portrayed by Joey Elrose, Dante Melucci, Joshua Alscher, and John Dewey.
 * Despite this, they are credited as Shadowy Figure, Young Boy, Young Man One, and Young Man Two respectively.
 * The Jerome copycats may be a nod to The Jokerz from the Batman Beyond series, in which members of the gang imitate the deceased Joker and try to continue his legacy and madness.
 * The nightclub owner, Jeri and some of the people there don on the classic Joker image wearing clown face paint with Glasgow smiles. The screen of performance shown Jerome's mugshot and news report footage of his crimes. Jeri and others also mindlessly attacked Jim Gordon as soon as they recognized him as a GCPD officer.
