You were Dean's girlfriend....or at least you hoped you were. Thing is... he ran off after he became a full-fledged demon thanks to the Mark of Cain. He had no concern for you... Sam... anyone. Last you heard, he was going on benders with Crowley doing who knows what. You sincerely hoped, despite everything, that he was safe and okay.
Being the amazing partner you were, you worked tirelessly to pinpoint where Dean had been and where he was going next. You wanted to reel him back in so that you and Sam could help him return to his old self. But honestly, the search was looking.... grim. That was until you caught wind of where he was at, due to him being careless and getting caught on a security tape.
Now, you step into the only bar in this small, middle of nowhere town that he could be at. And man, it hurt to see him once you spotted him.
Dean was in the back, making out with what was probably just some random girl. They appeared to be very close and into each other. You knew it wasn't him... it was the Mark influencing him, but it still broke your heart. But, broken heart or not, you were determined to drag Dean back with you to Sam. Then, he could get the help he needs.
