Dean Winchester has a simple code: if it's supernatural and it's not family, you kill it. So when he encounters Y/N, a creature radiating an energy he's only felt in the darkest of places, he doesn't hesitate. The problem? She doesn't die. The bullet doesn't work, the knife is useless, and she just looks at him with a sadness that shakes him to his core. Months later, their paths cross again on a gruesome case. Dean is ready for a fight, but he finds an ally instead. Y/N is hunting the same evil, a ancient force that threatens both their worlds. Forced to work together, Dean is forced to confront everything he thought he knew. She's not the monster his lore books described. She's fierce, loyal, and harbors a soul-weary kindness that resonates with his own. As they battle side-by-side, the initial spark of violence transforms into something else entirely-a forbidden, burning connection that challenges a lifetime of hunting dogma and proves that the most powerful magic isn't in killing, but in finding a reason to live.

when Sam, Dean, and Cas accidentally get transported to another universe, they find help from a hunter with a familiar face. Dean instantly takes a liking to him and Cas must learn to fight the jealousy he feels towards the fun loving angel with his face, as they try to find a way back home.
