One of the more conspiracy-theory like theories surrounding Fox's Gotham is that the show's Penguin, played by Robin Lord Taylor, will actually turn out to be the Joker, with somebody else taking up Oswald Cobblepot's name and becoming the Penguin.
MTV brought these rumors up to Taylor himself, to get his take on them. Unfortunately, since he's not responsible for actually writing the show's plot, just playing the character, he doesn't really have much to offer except his personal opinion on how likely this theory is to come to pass.
"I find it incredibly unlikely, but at the same time, I have no idea what could happen," Taylor said. "I get the scripts and I'll read something, and I will be just as shocked as everyone else is when they see it happen onscreen."
It's worth noting that parts of the theory hinged on most of Gotham's residents believing Cobblepot to be dead, leaving his name up for the taking. Since then, he's returned to the scene and is known to be alive, so it's hard to see where somebody else could become the "true" Penguin at this point.
Gotham airs Monday nights on Fox.
