This short video contains no footage of our heroes, antiheroes, or villains. It’s merely a riddle. Of course, the video gives you the answer as it progresses. Puzzlers should pause it immediately, to see if you can figure it out for yourselves.
It’s a nifty way of reminding us that the Riddler may be gone, i.e. frozen in a block of ice and put on display by the Penguin, but not forgotten.
My current theory: Penguin will be forced to unfreeze Riddler, to help him with a particular problem. But when it comes time to neutralize him again, Riddler will not go gently into that good icicle.
Gotham doesn’t just title its episodes. It also titles its seasons. For example, the first half of Season 3 was known as “Mad City,” while the second half was called “Heroes Rise.” The title of Season 4: “A Dark Knight.”
