Gotham wraps up season 3 with episode 21 and 22, “Destiny is Calling” and “Heavydirtysoul.” Here’s what you need to know to watch the season finale on TV and online.

The season finale of Gotham is upon us and things are about to get very interesting.

Ra’s Al Ghul is about to make his presence known in Gotham City. Bruce Wayne heard the Shaman’s final warning that he wasn’t the one in charge of the Court of Owls, and that this whole plan for Gotham’s fall was orchestrated by someone else. That person would be Ra’s Al Ghul, Master of the League of Shadows, and the man who would eventually be responsible for a solid chunk of Bruce Wayne’s training.

Fish Mooney is back and she came for Penguin. Now that she has him, what will she do next? Will Riddler be content that his arch nemesis will not die by his hand? We already know that he was obsessed with the mystery of the Court of Owls; will Riddler go after Penguin just to secure the ability to kill him himself?

There’s one final mystery that we should mention: Harley Quinn. Gotham showrunners have hinted at the appearance of Harley Quinn before the end of season 3. While many fans have speculated that Barbara Keane is somehow connected to Harley Quinn, there are more compelling reasons that she isn’t the one to become the future Joker’s girlfriend. If everything holds up, we have to believe that she will show up during the two-hour season finale. So keep your eyes peeled for Harleen Quinzel because she should be on her way!
