Author's Note: Here's the happy ending. It's short, but sweet, and I hope you enjoy it! :)

When he opens the door and walks out of that building and into the sunlit world - grimy and sweaty and a bloodied knife and clothes - it doesn't take five seconds, and he had barely even seen the morning glow of the sun before he feels a large, heavy weight collide into him hard, long and muscular arms wrapping tightly around his body. He nearly loses his footing but is saved by the wall behind him as he grapples to stay upright, the deep cold of the barricades cooled by the winter seeping through his clothes and into his back.

Small huffs ruffle his hair and tickle his cheek lightly, and then a harsh sob is breathed shakily into his ear, the body against his wracking and trembling with restrained cries.

And he barely hears the soft and scared confession of his brother's quiet voice, a gentle whisper muffled into his neck as his nose nuzzles up tenderly against his skin. "Thought you weren't gonna come back..."

He's still shocked by the sudden surprise of his brother's desperate embrace, but somehow through its daze, he manages to lift his arms slowly and hold him back, warm and gentle and yet, somehow, firm and tight around him.

"Don't ever do that again," Sam adds quietly.

Dean licks his lips, a small, watery smile tugging at them as he rubs a hand over his brother's back. "I'm back now, Sammy. And I'm not going anywhere."

Review please, and let me know what you think!
