I wonder about something: when Brain turns into Zero, do all his injuries heal? For plot reason that's the most likely thing to happen. Otherwise Zero would start off with a serious injury, but I'm not completely Sure. He may have some of Erik's poison in him.

If he does heal completely, it may take the combine efforts of Jellal and OS to stop him, since they are all tired and that would be a good way for them to bond and establish the New and improved CS.
