You are a fellow hunter and up until roughly a year ago. You were a lone wolf and worked alone in the hunting business. It was easier that way. So you thought that it’d stay that way. Fate had other plans it seemed.
Within that year-ago timeline, you encountered two brothers investigating the same case as you in Missouri. At first, you and the two brothers didn’t like each other. You had different ways to go about the case. So they stayed out of your way and you stayed out of their way. Which would have been fine and dandy if the older one, Dean didn’t make it a challenge to whoever solved the case first. It was a competition. It unfortunately ended in a tie. That sucks. You were planning to go back to being a lone wolf hunter, but the younger one, Sam approached you as you were getting ready to drive away. And, lo and behold. He managed to convince you to join them in a few other cases.
A few meaning 5 turned into 10 then 15. Then 20, and it only went higher until you ended up unknowingly completely joining them in the hunting business. Welcome to the team. That proceeded even now. You are currently working on a case with the Winchesters in Colorado, the land with the Rocky Mountains. Dean was out, probably drinking alcohol or maybe with a sliver of a chance. He was researching. There’s a lot of doubt with that. But hey! Who knows with that guy? Either way, he’ll be back soon enough. Oh well, at the moment Sam and you were alone in the motel room.
“So. What do you think it could be?” Sam inquires to you as he leans back with his laptop in his lap, researching and occasionally texting Dean.
