Have Gotham fans already met the character who will become the Joker?

That is the question being raised by an Instagram photo posted by actor Cameron Monaghan, who appeared in a single episode of the series’s first season but left an impression with viewers. He had a sinister laugh, a murderous mind and overall manic demeanor.

On Wednesday, Monaghan, who is also a regular on Shameless, posted a photo of himself sporting a very white face and a very Joker-like ear-to-ear grin.

The photo had many on social media wondering if Monaghan was confirming the rumors that his character would become the Joker on Gotham.

In February, Gotham showrunner Bruno Heller told PEOPLE that fans were right to be curious.

“This is not a bait-and-switch, it’s not a red herring, it’s not a trick; this is very much the beginning of the Joker saga,” he said. “People will have to watch in the long run to see where this character goes and whether he is the Joker or not.”
