"I've got a question: How high is your pain tolerance?"
During the Gotham portion of the major WBTV panel that took over Hall H for several hours Saturday night at Comic-Con International: San Diego 2015, the cast and crew started answering fan questions. When one fan was up, another grabbed the microphone literally out of his hands. While those on stage played along, calling for security to grab the "fan," he uttered that terrifying question above: "How high is your pain tolerance?" Head to about 14:50 in the video below for the moment in question.
The "fan" in question was actually actor Cameron Monaghan, who has been heavily teasing his return to Gotham in season 2 as the nascent Joker. First appearing during a mid-season one episode, his character, during questioning, issued out a laugh and a psychotic glee in the crimes he had committed. It looks like he'll be back, and a much more prevalent and direct threat.
Gotham Season 2 premieres on Fox September 21, 2015.
