I believe the tracker got turned on in the middle of the crash.

[So, yes. Absolutely.]

I'm still not sure how he talked B into letting him stay with the Titans after that. Probably realized that if he hadn't noticed it by that point, he could soak it. And Rook needed to be with his friends.

[After all, that had been the reason for the new Teen Titans. Getting Young Justice back together so that the kids HAD their friends.]
