This is the fourth time you've woken up in some dark room, tied to a chair, listening to The Riddler in the speakers trying to threaten you... Or flirt, ever since you started your vigilante career. You're obviously not the best at the job, since he knows your secret identity and manages to get you every time. But he's also really into you, apparently.

"I start with one, and end with four. If you say me out loud, then out you go. What am I?"

He's trying to get your number. Pathetic.
