Here's what we know about Darrin: He works in the mail room at Bison Bros., he plays drums in a punk band, he hangs out almost every day at the gym, and he was one of the first employees to use the cursed copier, using it to print flyers for his band.
He's also generally indifferent, if not outright rude to everyone he works with. Except Patton, for some reason. They seem to have a kind of unique chemistry going and can often be seen working out at the gym together. It leads one to wonder if there isn't something more going on between them…
(I'm a furry. Of course I went there.)
