While it wasn't clear what kind of role Vernon would be playing in the series, yesterday Grunberg posted a picture of Vernon and new Heroes castmate Robert Knepper, who plays the nefarious Samuel, ringleader of the mysterious Carnival. We're not sure if this means Vernon will be the latest member of the Carnival or not.
