Batman: Gotham Knights

You notify Oracle of the Riddler's plot and she hides her operation, which is, of course, set inside the Clocktower. You head towards the tower in the Batplane and disembark near the top of the tower where you saw a green question mark laying on the stone. It's a riddle.

"Time is short, so listen well
Or perchance we may see you in Hell
The light, it calls, for you to run
But cross us, hero, and it won't be fun."

You read the riddle over and over. You come up with two choices.
