No, not THAT Balloon Man. Still, the official synopsis for October 6's episode of Gotham is now online, and it's called "The Balloonman."
Focusing on a vigilante who is killing Gotham's corrupt, this seems to be setting the stage to answer some of the long-standing questions fans have had about Gotham, such as the question of why villains would go for outlandish costumes and identities if there wasn't a Batman there to pattern their behavior after.
Gothamsite has the details:
