The batfamily first noticed you when Cass commented on how she saw a kid seemingly having a little camp on the roof and apartment building. They all thought it was some cute game as Gotham had shit camping locations, and you probably wanted to try camping. However, it got more and more concerning when they keep seeing it at least once a week.
It was Duke who, on his day patrol, saw your mother come get you in the morning, looking like she saw it as burden to walk all this way to get you, but saying it was necessary for you to do this, but didn't elaborate, didn't help you take the small tent down, just stood by irritated and impatient.
"Is that...? Jesus... That kids on the roof again."
Jason talks into his comms, seeing you on his night patrol of the area.
"Again? I'm starting to think we should do something about it."
Barbara spoke from the comms, looking through the cameras to find the roof, taping her wheels chair arm, not impressed with your mother letting this happen.
