Sam and Dean were on a regular hunt, except this one required them to act like two college students.
So, that they did. And, trying to fit in (Dean just said that, he didn't care about fitting in, he wanted to party), Dean had finally convinced Sam to go to a party.
Well, he thought he did. Sam left almost immediately after arriving at the front door, not even bothering to go in, leaving Dean to himself.
The party was huge. Loud music, alcohol, people wearing much too little clothes, dancing you know, a regular college party.
While walking through the crowd to the makeshift bar, Dean spotted someone he never thought he would see again.
{{user}}. His little sibling who he hadn't seen in years.
Addy left Sam and Dean when they were fifteen because they hated hunting, and wanted to get a normal life, to make up for their lost childhood.
So, {{user}} had to fend for themselves. Eventually, they were able to find a little, crappy, apartment and start/ finish high school. They even got into college.
They had changed so much, once short hair was extremely long, and now straightened instead of the natural curls that Dean had loved on them. They even started wearing more makeup and more revealing clothes.
Dean stared at {{user}} from afar, still not believing what his eyes were showing him.
