Summary
“Goddammit, Gabe,” Sam gritted through his teeth. The mirror stared back with a face fifteen years younger. He grabbed his jaw, ran a hand through his hair, and started laughing. Cracking at first, then manic, until the tears came.
After watching Dean die on that spike, Sam was thrown back into the past to Mystery Spot. The same plastered early 2000s themed walls. The same Wednesday morning that tied Sam to his brother more than ever before. The same damn song playing on the radio like nothing had changed, yet a new hell awaits.
He’s convinced Gabriel’s behind it, but the trickster swears it wasn't his doing. So who sent him? And how was Sam supposed to carry the weight of the world on his shoulders again, knowing exactly how much it cost the first time?
This story twists canon into something new: a Supernatural series centric journey. There’s still Destiel, still monsters, and an omniscient God that doesn't know how to leave well enough alone. The Charmed crossover adds new allies, new chaos, and just enough magic to make it hurt a little less—
—or maybe a little more. -

Summary
Dean had heard once, that you weren't supposed to mix pills with alcohol. It made you weak and unstable.
Delirious.
He squinted bleerily up at the brilliant light, despite the sting from his eye's currently rupturing veins.
A blue sun hung overhead.
Pulsating.
Visceral, like the beating of a heart.

Something... no... Someone who could never leave him.

Summary
Set days after the events in Shadow (1.16), Dean and Sam are trying to get as far from Chicago as they can when an unexpected and yet familiar arrival throws their world into disarray. Dean didn't ask for a glimpse into his and Sam's future, and he's still not sure he wants one, especially not when his future self starts talking about angels and miracles, like either of those things could possibly exist.
"Okay, let's say you're right. Let's say at some point I'm going to travel into the past, meet myself, and then force myself to take a cross-country road trip with myself so that I can find some dude I refuse to talk about. The hell, Sam? Does any of that make sense?"

Summary
He cleans the filth of Hell away from her soul and it burns. Not like fire, no, but like a steaming bath on the edge of too hot. Agony for a split second before it soothes, before it heals.
Her skin feels scrubbed raw and bloody. The hand does not leave her arm and it’s grip only grows tighter as they take flight.
They rise and he is purifying her, carving out the dried blood from beneath her fingernails, scraping it from the roots of her hair, from the inside of her eyelids. Will there be anything left after the holy light fades? She doesn’t know if there’s enough of her humanity left after the corruption is washed away to survive.
The holy light holds her with so much tenderness she could cry.
It’s been so long since she’s been held.
