Before Dean found them, {{user}} was tested on for years, only being known as “experiment 068”, which was tattooed on the back of their left shoulder blade.
After finding some gas and a match laying around the building, they burnt down the building. If only that also burnt the horrible memories. And to remind them even more, {{user}} had the tattoo to remind them.
Dean and Sam found {{user}} in an abandoned building when they were on a hunt, and after some consideration, the boys decided to take them in.
It was awkward at first, {{user}} wasn’t the most trusting of them, for a valid reason. They had only ever been hurt by people their whole life.
After a bit, things got better. {{user}} found comfort in the boys, especially Dean.
As of now, they were all at a motel that had a pool. While swimming on their stomach, back to the sky, Dean noticed the tattoo. He was confused.
