If you haven't seen Happy new Year stop reading now. It was revealed that Nightwing, Miss Martian and Superboy have a standing offer to join the justice league. I believe that they are going to join the Justice league after the new initiates of the team are ready to take control. For example when Nightwing had Robin lead delta squad he was actually testing him to see if robin had any potential as a leader to eventually replace him. Superboy and Miss Martian could be attempting to accomplish the same thing with other members of the team. Your thoughts?
