FOX has released the latest trailer for Gotham’s final season, which warns viewers to prepare for Jeremiah’s final act of insanity. Fans that have been following Gotham news closely might be surprised to remember that oh, yes, the show hasn’t actually ever shown that Cameron Monaghan’s Jerome-then-Jeremiah Valeska is in fact Batman’s greatest foe, the Joker. Everyone just knew. It’s been teased and teased to death, with savvy fans figuring it out very early, but now, with the latest trailer promoting the show’s Feb. 21 episode, it’s official: the Clown Prince of Crime is here.

Written by Tze Chun, the official synopsis for next Thursday’s episode, “Ace Chemicals,” reads as follows:

“Gordon races to uncover the criminal element threatening Gotham’s reunification with the mainland; with the help of the Mad Hatter, Jeremiah returns and organizes a twisted re-creation of the murder of Bruce’s parents.”

Fittingly, the Joker and Batman are having their origins melded together, establishing the toxic relationship that these two have shown off since their very beginning. What a fitting time for the Joker to make his rise, just as Gotham comes to an end. Almost like a punchline.Gotham finally shows off the Joker on Feb. 21. What do you think of this introduction?
