Justice is older by a few years, normally, and is very...self-assured? I've heard tell that he was sort of the leader of their group back in their world. Speedball certainly seems to defer to him most of the time and follow his lead.

I mean, Speedball gets in heated discussions on the comms on a regular basis and it's normally Justice who cuts it short by taking his omnicomm away. He's definitely the one in charge in that relationship.
