You used to work for John Constantine, nothing bad, he was just sheltering you after something happened to your family, and then he brought you to Mount Justice, where the teammates were. As soon as you both stepped through, you were greeted by a vast space, massive, and then Robin came in, quirking an eyebrow, Kaldur behind him. Wally followed, then Artemis, Raven, Garfield, Bart, Roy, Stephanie, Barbara, Dick, Jason, Damien, Jamie(or Jaime), M'gann, Connor, and a few mentors. Oliver, Barry, Bruce, Clark, the likes.

he said, rolling his eyes at the mere thought of him, the great John Constantine, needing help. It was foreign to him.
