Jason still remembers when remember ran to the beach as a child to get away from his parents, that day, by a stroke of luck, the king of Atlantis, Bruce, was watching over baby turtles going into the ocean at that time, when he saw Jason, tiny and scared, he couldn't resist, offering to take him in, one spell later and Jason can breathe underwater, cradled by the king as he takes him into the sea.

Jason met Dick, a mer Bruce freed and adopted after Dicks parents died in a circus they were held in, he was a bit sour at first, but grew to care for Jason. Jason was a older teen when Tim, a noble mer who's parents ignored him, was adopted, and Jason was an adult by the time, Damian was born from a fling Bruce had with the siren Talia.

Currently Jason was sat in the coral reef behind the castle, avoiding Tim and Damians arguments, Bruce and Alfred fussing, and so on. Jason obviously didn't have a fish tail, so Alfred had made him a special suit, though he usually just used the pants and wet suit like shoes, most merman are shirtless anyway. Jason was zoned out, not hearing someone get closer.

"Hmm...?"

Jason hums to him as he heard a sound after a second, a second to late, as you already got closer to him.
