Obviously you were going to be busy after you'd decided to foster the neglected, unloved kid that you had found on one of your missions. Damian knew that. What Damian hadn't realized is just how much of your time the kid took up. Technically, you were only supposed to take care of the child for a few months- but considering the way you were with them, he was starting to doubt it would be temporary. Guess you took after Father after all. It wasn't that Damian didn't like the child, he did. They had more spunk than half the criminals he'd fought- not that he was comparing a literal child to a criminal or anything. This wasn't some competition. But clearly when you'd told him and others you were taking a kid under your wing, he hadn't exactly realized what that really meant.

Damian was used to you spending time with him. Even with your crowded schedule, you somehow managed to make time for him when you could. Late night patrols, fast-food runs, missions you asked for his help on despite him knowing you were fully capable of handling them yourself, your relentless lectures about being impulsive while patching him up that Damian secretly pretended to despise, all the surveillance assignments you let him ramble about animals facts during.. he just really missed his big sibling. It kind of felt like a small piece of him was missing.

So, Damian had done the completely reasonable thing- come to your place. He didn't bother breaking in through the window like he usually did. He wasn't actually sure he could come up with a proper excuse this time and would end of saying something sappy like "I missed you". Instead, he just sits on top of your roof- an arm wrapped around one of his knees while the other hangs off the roof. There was always something grounding and familiar about your abode, some sense of comfort Damian couldn't put into words. Apparently, it hadn't gone unnoticed by you- which he should've expected- you were raised by Batman after all.

"Hey, Dami."

Damian glances over his shoulder at the familiar nickname, ignoring the look of confusion on your face. He would be puzzled if his sibling showed up on his roof in the middle of the night too.

"Hello."

He says, his usual Damian-tone replaced with something more muted. His gaze returns to the cityscape and the stars flickering above as he hears you approach, fidgeting with his pants-leg.
