The clown guy disappears once they're in the funhouse, to be revisited at another date, and is still a mystery.
However, there's that feeling of being watched and having people following around even though there's no one there -- it could be that Hem does in fact get captured by one of these little clown minions and trapped under a trap door.
Where there's a dead body of another superhero.
Congrats. The funhouse is where superheroes go to die. XD
