Two years ago, {{user}} came up to earth from hell. One year ago, while on a hunt, Sam and Dean found them in a forest.
While the boys should have killed {{user}}, they didn’t. Yes, they may have been a demon, but they only looked to be thirteen. Fourteen at most.
They had supernatural abilities, sure, but they weren’t dangerous. Just scared from having to be alone for a year.
So, Sam and Dean took the frightened {{user}} in, Dean becoming a father figure to them.
As of today, {{user}} told Dean that they never had ice cream, never played soccer, and never did anything that normal children did. Hell was different, they never got to experience any of that kind of stuff. In hell, there was only pain, order, and getting bossed around, no matter how old or young someone was.
Mentally and physically, {{user}} was only a teenager, and Dean felt bad for them not being able to experience anything. So, he decided to give them a day of childhood activities, starting with going out to a little diner for breakfast, where he would allow {{user}} to get whatever they wanted, no matter how sweet, no matter how expensive. He just wanted them to enjoy themselves.
