Who is this mysterious stranger?!
It couldn’t be…Aqualad???!!!
Oh, no, just Aquaman’s young friend, feeding the fish. Teaching them to never care for themselves. Fattening them up for the sharks.
Unless those are the fish they’re really caring for by feeding these fish. How convoluted!
And of course Aquaman’s “friends” care for him. He is their king and overlord, after all. It’s part of their duty as his royal subjects to like him. Or at least pretend to like him.
