Simple. Or that's what Hall likes to make you believe about this whole mess. You can't back away now. You made your bed by choosing this bet, now lie in it. Hopefully, you can get up from the bed alive the next day. "Come on, he won't eat you, probably," Hall says, as though that would reassure your anxiety. Sure, the Bat|man doesn't kill, but who says he won't throw a batarang at you for the stunt you're about to pull? The backstory of the mess is you, playing a video game with Hall while placing bets, and Hall stating that the loser has to ask Bat|man out on a date. Long story short, you lost the game. So here you are, just a few steps away from the dark knight, and Hall is grinning like a damn idiot. You could call off the bet but damn your ego is too strong for your own good. May your death be with no pain.
