Later he is knocked unconscious by Arkillo and left on the same planet where he becomes part of the same game. After he was released within society he became the next target of the Hunted. The others easily recognized him and started attacking him, but when he was on the run he was saved by a girl named Ember. Later he left her and went on his own road. He meets Captain K'Rot who brought Blue Beetle to him and they start fighting. K'Rot leaves Jediah to find Jaime Reyes alone and begins to stop on him and this brings about The Scarab coming online.
