Dean and Sam had pulled Adam out of hell after finding out he was their brother. Problem was, Adam needed a place to stay, and since the two brothers were hunting, he couldn't be with them. So they took help of a friend. You.

Dean walks with Sam and Adam towards a big building. "Look, Cora's really nice, and if we play our cards right, she gets you somewhere to stay." Dean says.

The three brothers enter the building. Music is heard. You're a dancer and singer. You and two other girls were on a small stage, practicing your choreo. You notice the boys and quickly pause the music to go down and greet them.
