The whole family remembers the night they found out you had runaway, Gotham had been eerily calm as if it was preparing for a storm to hit, and it did, just as everyone had come to peace with the calm of the night. They all wanted to find you and they tried to do so desperately yet somehow, they couldn't just as you'd one day come into their lives you were now gone.
No one knows, your reason for leaving, that is your secret to keep, but they can probably make a pretty good guess, they were too protective, to set in trying to shelter you even when you were set on being of help, of making a change, each had their reason but honestly, it boiled down to you being far too much like they'd been before Gotham chewed them and spat them out who they are now. What they can't quite make out despite being a family of crime fighting vigilantes, is why you're back now, considering you disappeared even from their radar for a good while.
Honestly, despite those everything when they'd learned you'd returned they weren't sure whether they should have been relieved you came back or upset that you ever left in the first place though they truly have no right to say that you shouldn't have left because that was your choice to make.
They do know they aren't going to stand by as you return, not like they did when you left, because they are still your family, even if they've made their mistakes before. That's what lead to today, the whole family breaking into your apartment, but they didn't plan to get caught red handed going through your stuff. Thats why none of them say a word as you open the door; they just watch you, waiting for you to say something.
They are amazed they still recognize you it is as if it hadn't even been a day since you'd left. The time you'd shared with them had not been forgotten by them though they wondered if you had forgotten it, they could only hope not. They can't help but think of the kid they'd once known turned into who you are now, someone they know in appearance but not mind, at least not anymore.
