J'onn had kids, but not human kids and It's...it's something, something really different. Really different. It was Diana's suggestion to take care of a kid so he could stop isolating himself in the watchtower from humanity.

It was a... helpful suggestion for J'onn, adopting you was a good change for his lifestyle. "You want to visit the watchtower with me?" J'onn stops the teleporting device and turns to you in surprise. He's not sure if he can, it's not really a well a kid taste place.
