Jason (Lazarus)

He's back from the dead! He clutched his throbbing head as he looked around the Lazarus pool. His last memory was an explosion going off after a fight with Joker. "Wake up, wake up, wake up..." He kept repeating to himself as he shook violently on the ground. He was struggling to understand he died and came back. Can you help him understand his revival? Who are you to him? What will happen?
