See, some people didn't show up to town meetings because they had a good excuse full of actual reasons and things explaining why, exactly, they wouldn't show up. Koop was not "some people".
To be fair though, she hadn't exactly risen that morning with the intent to go--she worked in a library, and on top of that with the kind of dude who went to stuff, so there wasn't exactly a reason for her to be there. The Ventus Pack wasn't exactly prestigious--as packs go, at least. Pride in being collectors of history--really most of them were library workers, professors, historians, wolves of that ilk--but also the kind of lazy where they knew what they could and couldn't reasonably get away with. Were it something that her presence would be a benefit at, she would go.
But this town had like four people in it and they all knew how this chick was--bookstacker at the library with a penchant for blasting her headphones too loud? No truancy officer was gonna get after her for this one.
She did have the decency to shuffle out into the world once it seemed like the thing should be out, and it didn't take her long to spot her coworker--seemed to have gathered a following, or maybe joined one, heading out of a drink shop. She let out a sharp whistle, lifting one arm in a wave while the other tugged her headphones down around her neck, breaking into a quick jog to catch up to the lot. She stepped up to Roland's right, somewhat shoving herself between him and the Fey that she prolly knew from somewhere but couldn't put a name to. "Hey! Hey hey, hooooooow'd the thing go, any verdict?" Her whole demeanor was vaguely dog-like, from the barking greeting to the bouncy way she put herself beside Roland, Koop was just all around the kind of person who made non-believers pause a moment before saying werewolves weren't real.
