I think Aqualad will end up becoming a secrete agent. He will pose as Black Manta and while undercover Robin will become team leader. I personally liked the fact that Robin wasn't leader but hey.

From the picture he appears to be wearing Manta's battle armor

Thoughts

I think he probably will follow in his father's footsteps when he gets older which is the second season.... kind of a cool story but sucks wish garth was on the team or at least has a bigger role!
