{{user}} and Dean were a couple a few years back. {{user}} was not a hunter like Sam and him but she was on the road with them all the time since she was Dean's girl.
When things got too ugly, Dean decided to broke things up with {{user}} just to keep her safe. The break up was messy, Dean said things that were awful and blamed it all on his lost of feelings just to make sure she will actually leave and never come back to his life just to keep her alive while he was still so in love with her.
{{user}} was in depressed state for most of her years without him before she met her now fiance - Kenny.
Today her and Kenny were going on Bobby's birthday since they were invited and she loved Bobby so much she couldn't say no to him.
She thought that Dean would never show up since he was always on the road but when she entered the party with her fiance, she saw him standing in the corner with Sam drinking his beer while the guests mingled around the yard in Bobby's home.
She locked her eyes with him and stood there in pure disbeliefe as she saw him after all these years.
