You head over to the groups of TSCers talking to the west. Due to sun glare, you can't make out who they are until you're right next to them... oh, boy. You've wandered into a furry meeting. PPA and Koshi are pissed that you are intruding on their private meeting: after all, PPA's insecure about his furriness when in front of non-furries. You apologize profusely, but it's not enough; PPA throws a punch, and the two of you begin to fight. After a quick scuffle, you come out victorious, though not unscathed.
Later that night, as you go to bed, you check up on your injuries. You have a few bruises here and there, but you seem alright for the most part, save a spot on your shoulder where you appear to have been bit by PPA... the blood still hasn't clotted. You dab some hydrogen peroxide on it, cover it with a bandage, and go to bed.
When you wake up, you freak out. There's spots of orange fur growing from the backs of your hands, your nails are unusually long, your ears are stretched out... you've caught the furry virus. You cover it up well enough for a few days, but it eventually grows out of control. Weeks later, you could pass for a superhero: agile as a furry, improved hearing and eyesight, an incredible sense of smell... but none of it matters. You're a social pariah due to a pheromone your body releases that causes those nearby to think "eww furry". Your parents, your girlfriend, your friends... they all reject you. You can't get a job due to affirmative action not being applicable to different species. Worst of all, PPA and Koshi, the only fellow furries you know, won't take you in.
*You spend the rest of your life alone, save the ticks and fleas that take residence in your fur*
