Warning: The following contains possible spoilers for "Gotham."

Throughout season one of FOX's "Gotham" a handful of Batman rouges were paraded throughout the major storylines, yet it was Jada Pinkett Smith's Fish Mooney, an entirely new character created by showrunner Bruno Heller, who demanded our attention. Mooney ran the underworld with a sense of flare that felt right at home in a comic book-based series, yet was seemingly killed off in the finale. However, if we've learned one thing from TV it's that if you don't see a body, then it didn't happen.

Mooney was found inside the Indian Hills facility in the Arkham District during Monday's mid-season finale. Does this mean Smith will be returning to the role sometime in the near future?

If you blinked, you could have missed it. But Mooney's signature highlighted hairdo could clearly be seen floating in a tank within the facility's secret lab. We don't know much about Indian Hills at this point, though several villains have popped up there and the soon-to-be introduced Hugo Strange will likely join them when the series returns in 2016. But what scientific value do corpses and near-dead villains hold? What's the end-game here? The last we saw of Fish she was plummeting to her (apparent) death. Now she's a lab rat.

In the original comics, Strange has a habit for creating grotesque creatures with genetic splicing and other forms of experimentation. He'll likely be up to similar tricks in "Gotham," but why he needs Fish remains to be seen. Hopefully, Smith will make at least a brief cameo when the show returns to Fox on Monday, February 29.
