Damian had never met Jason Todd before now, but the feeling in the room was suddenly painfully familiar. The expression on Grayson's face was one he usually expected to see on Drake instead and in the slightly disturbing silence that followed the current youngest of the family couldn't help glancing over to him and Stephanie as he wondered whether things were about to turn violent. The air of mistrust, disapproval and awkwardness certainly felt different when he wasn't its' misguided target. Luckily the two oldest former Robins seemed to be taking a civil path out of things and just talking rather than shouting and attempting to throw each other bodily through windows, though Damian didn't see why exactly that was. Still, it didn't solve the problem that Tim was right there and in another few seconds the interactions he'd been dreading would be forced upon him. He could already feel his knuckles itching slightly as he wondered whether his direct predecessor as the Boy Wonder would just glare at him like he hoped he would burst into flames or openly accuse him of killing someone lately. Even more fortunately the doorbell rang before anyone could start talking to Damian, and he only stopped to say "I'll get the door!" before ducking out of the room and running the length of the Manor's entry room to open it. If he was fast enough he could probably keep running right out the door, find the League of Assassins gear he'd buried nearby and be disguised and on his way to Gotham City proper before anyone stopped him. Maybe he could make sense of all the unnecessary emotional content of both the evening and the whole wedding the proper healthy way in brutal combat against worthless human scum and maybe if he broke enough people's bones tonight on the street he could avoid doing the same thing at the wedding tomorrow and maybe- Maybe the person standing in the doorway would be someone he wouldn't be able to get past if he tried. A dozen strategies for slipping past the newest arrival had run through his head in the time it had taken for him to run to the door and all of them were useless against Cassandra Cain. The surprise of seeing her had shaken most of the plans out of Damian's head anyways. On some level he'd known that the other former protege of the League of Assassins was Batman's adopted daughter but he'd had no real context for any of that before now. Suddenly seeing her on his doorstep was still a shock, even with a radically changed appearance. He didn't even have time or space leftover to process the idea that he had just been caught in the act of trying to run away and feel ashamed about it. He was too busy suddenly trying to conceal the fact that he had any emotions at all, much less surprise or shame. "...Cassandra Cain. Well...come in." He wasn't sure if the night had gotten somehow better or infinitely more painful. Only that his chance to escape it was probably gone forever and he likely couldn't even take care of it with proper violence now.
