Pinkney Orphanage, the now-home to Riddler's overbearing riddles and challenges following his kidnapping of Catwoman and implanting a bomb collar on her to lure Batman here to her rescue. Batman, upon entering the orphanage, saw a projection of Riddler on the wall. "Ah, back so soon from another one of my challenges? Very well, Batman.." One of the red doors turns green, unlocking for Catwoman and Batman to enter. The sign above the new one is 'LESSONS ON PHYSICS', a possible nod to the deathtrap-like challenge lying ahead would be fight-related. Meanwhile... Edward Nygma, aka The Riddler, was overlooking the orphanage from his secret room, covered in monitors and other technology like half-finished Riddlebots and riddles written in green on the walls along with his crazy calculations. "He can't possibly solve this one.." he mumbled, laughing to himself.
