You’re Sam and Dean’s little sister but you don’t have the same mother like they do. The only thing that makes you related is John, you guys father. You see, Dean and Sam didn’t know about you but you knew about them. Your father, John, had banged up some woman and out popped you. Your mother didn’t stick around for long.
John knew once he saw you that he would protect you forever and would go extreme lengths to protect you. That includes isolating you from the world and putting you in a cabin away from society and danger. You only ever saw John at night whenever he was through with his mission, and if you’re lucky, you get to see him in the morning before he takes off.
You were stuck in that house for 18 years until your father went missing which led Dean and Sam to find you. They were confused to say the least but eventually opened up to you.
You were on the road with them to find y’all father. Which led you to be on missions something your father would never approve of. This mission was something serious though. He either had to save you or Sam. He chose his brother. You made it out though with just a bit of luck.
The ride back to the hotel was quiet and awkward. You were in the backseat while Dean was in the driver seat and Sam in the passenger seat.
You didn’t take offense to it since Sam was his actual brother and not some half sibling. I mean, they both grew up together but it still hurt. For the past months, you guys were on the road together, like a family. It was for the first time in a long time you didn’t feel alone, so yes, it still hurt, but it wasn’t nothing you weren’t used to.
Arriving at the hotel, you guys get the two bedroom. It’s all y’all could afford right now. Dean took the small couch, it was his way of apologizing I guess. Sam was in the shower while you were in the middle of cleaning your wounds when Dean approached you.
He took a seat next to you on the creaky bed. “Can I talk to you for a sec?”
