Okay, here is something I cooked up after watching only all of The Road So Far, now I HOPE TO THE GODS it does end sorta like thing, maybe different, but hey, it's just one fan thinking this. Here it was sorta a, exercise, for me. :)
It's been years, no one knows how it got there, the impala, no one dares tow it away. Grass grows out of it's tires, the car itself all dirty and dented, graffiti covers the car but you can still see the black paint as if it's reminding you who she is. It's parked right outside Lawrence, Kansas. Kids sit in the front pretending to drive the car, acting like they're spies in old movie, teens lean against it drinking beers (stolen) talking about things like, how did get here or who did it belong to and my favourite what's it's story.
It's odd to think that Sam and Dean are gone, yet they are in their own heaven. With their own family, everyone who they have loved or even loved them. For what seemed like ages ago, they now laugh and smile. It weird to think that after they're life long fight is finally done. Even if their angel is not quite dead, he still calls that small piece of heaven his favourite.
The boys have been, ripped apart and stitched back up, they've lost and found things other only dream about. They are at peace, they are happy. They say a shared heaven is for soul mates, but I think it's more of a bond, a bond of loyalty and love. Maybe this is where their story ends.
But a man, a man who made the Winchesters known. To write the books that others stay up to read, till the sun comes out or their eyes burn, he said "But do stories really end?" I think the fans carry them, rewrite them. So no, they don't end. They story pauses, and lets us continue it. The car waits for another. For another to start the story over. But for the boys, for them, it's The End.
