"Raucous" and "packed" are about what Jack needs right now - he's back in town and doesn't have a friend in the world, so whoever's having a good time in there can afford to let him soak a little bit of it up, he thinks. He's still got that jacket, even if it's somehow more worn than before, and even if he's managed to patch that bullet hole over, the 1%er patch (the only one he didn't tear off) is still on his shoulder. It gets him in trouble sometimes, but fuck if he can bring himself to throw it away.
When he actually gets inside and sees who's celebrating, he isn't actually all that surprised. He takes up a spot at the bar instead of introducing himself, orders tequila - actually, why don'tcha just leave me the bottle, sweetheart - and takes it in. He's doing good for himself, Tony is, and Jack is... happy for him. He honestly is. Nice duds. Nice party. Nice pair of tits on either side of him, too.
The newest round of cheers goes up, and Jack raises his glass with them. But he's got that jacket, and he's got that scar, and no doubt someone's going to let Tony know that wow, you will not believe this, it's Jack. Over there, look.
promptly does one of those obnoxious "sits nearby, does nothing" tags
