When was the last time you had a good night's sleep? One where you really felt recharged when you finally crawled out from the paradise of your mattress? Jason Todd couldn't remember the last time he slept at all, let alone slept well. A life involving neon spandex and the possibility of getting frozen in a block of carbonite had a tendency to cause sleepless nights. Not to mention Wayne Manor was just too damn quiet. Bruce did a lot to ensure his privacy. Batman might've forbidden his little bird-lings from patrolling, but he never said anything about sleeping. Sure, Jason would take advantage of the luxuries of running water and a personal bathroom, one couldn't become Robin without almost superhuman management of their internal clockwork, but he was noticeably absent from the wedding reception. 

Rather, he found himself watching the gathering unfold below him from a small sitting room on the manor's second floor, wearing the exact same set of clothes as the night before and surveying effectively every attendant. Honestly, a public wedding was [i]asking[/i] for trouble, and Jason was more concerned about his extreme lack of firearms than how well he looked for Gotham's social event of the century. Damian had given him a particularly venomous look when he was up and getting himself ready, but screw him, Jason was old enough to make his own clothing decisions, or rather, defiant enough to tell Bruce to stick it. Lucius had even stopped by to try and rouse him, but he knew better than to drag it out. In that way, Jason could be just as if not more stubborn than his mentor.

Besides, the sleep deprived ex-crime lord didn't have any real reason to be there anyway. Time had passed him by. He could see it just by watching them. The way Stephanie antagonized Damian or let her eyes linger on one Tim Drake. Cassandra did much the same to his immediate replacement. He never had any of that. Dick was too busy in Blüdhaven to give him any bother, Barbara was too busy judging him for not being Dick Grayson. The rest didn't even know him. Four years in the ground and four years away from Gotham. The family had grown, and he was left as an outlier. 

Before he knew it, one Lucius Fox had apparently summoned the riff-raff inside for the ceremony. Jason figured if he had any obligations, now'd be the time, so he turned around and made his way to the general sound of voices and violins.
