Someday

After burnout father John Winchester is killed in a freak car accident when Dean is 19, the boys’ lives take an entirely different turn than they could have. Sammy gets to finish school properly without learning to fire a gun before he can work the TV remote, Bobby gets to see the two of them grow up into a stable, normal life, and Dean - well. Dean gets to experience first-hand the utter mundanity that comes with average small town life. That is, until a man with eyes like an angel decides to walk into town and throw most of what Dean Winchester thinks he knows about life straight out of the window.
