Bruce frowns, double-checking his records. Yeah, this was the place.

It had been surprisingly difficult to track it down. Or, maybe, not surprisingly, on second thought. He shouldn't be surprised you'd know how to disappear. After all... he'd trained you himself.

And disappear you had, with hardly a word. Little more than an emptied room and a note that told him, 'Don't look for me'. Well, he was the World's Greatest Detective. Of course he was going to look for you.

Because something could be wrong. Because you could be in danger. Because maybe this hadn't been your choice, maybe you'd been forced, or tricked, or coerced, or taken. Because he didn't know why else you would have vanished like this. Because he couldn't nail down what might have gone wrong. Because he needed answers.

Because you were family, and family matters. It has to.

So as long as it may have taken, he'd tracked you down. He'd followed leads, rumors, dead ends. And he was finally certain he'd found where you were. He'd thought about different ways to reach out - sending a message, leaving something to arrange a rendezvous point, even sending another family member that perhaps might feel less like a... confrontation. But ultimately he'd decided it had to be him, it had to be in-person, and it had to be unannounced. Because he didn't know why you'd run before - and he didn't want you to run again now.

So Bruce triple-checks his records - just in case - before taking a deep breath, and stepping forward to knock on the door.
