In their line of work de-aging is not an uncommon occurrence.
Tim wouldn't say that it's a monthly occurrence but definitely a yearly one. What is unusual is the fact that it's a villain specifically Ras. Seeing him experience the consequences of his actions is always a fun experience, but having a de aged version of one of your main nemesis is a little bit of a problem.
They've never seen him younger than the about 60 that he usually runs around us. In front of them was a 6 year old with a mix of black and white hair, with heterochromia that gave him red and green eyes. He wrapped himself in his original clothes that were way too big for him and glared at the heroes in front of him.
Nightwing is the first one to snap out of the shock.
“hey there buddy” Nightwing says in his usual victim tone as it's very obvious that the kid has no memories.
“don't come near me” The kid seems to look around, probably trying to figure out where he is “where's my mom?”
that breaks their hearts, with how old he is originally is there's no doubt in their mind that she's long dead.
“Something happened to you buddy that we're trying to figure out and if you could help us that would be great” Nightwing tries to gently ignore the question and stare off into another topic.
“Mom doesn't leave me” he seem to be trying to make themselves seem brave but they can see the tears forming in the sides of his eyes ”did something happen to Ellie”
“how about you tell us your name, who Ellie is and what your mom's name is and we'll see about how we can reunite you. Is that okay?”
The child then looked around the room again. This kid version of Ras was trying to figure out if he could trust them.
“it's Dan, and that's all you're getting until you tell me where I am“
