Cross My Heart

Guardians

Note: So, I know that I had said I wouldn't touch Castiel slash…yeah, I lied, this story is going to involve some innocent Castiel slash. As soon as Twisted Ingénue gave me this wonderful idea to play with, I couldn't help myself. It grabbed a hold and is my new favorite thing. I own nothing, not Supernatural, nor the lyrics below from Hawthorne Heights Saying Sorry, and dear, I hope I'm giving your idea justice.

Summary: Castiel was always destined to be Sam's angel.

Saying goodbye,

This time,

The same old story,

Seeing you cry,

Makes me feel like

Saying sorry

Before they were born, every one of my father's creations, he assigned one of us to them. We were the chosen ones, and it was out job to guide every one of his beautiful gifts throughout their time on creation. It was only his best, and most trusted. And he was proud to have that designation.

Every soul on earth is destined their own individual angel. To be a guardian, it is a divine designation and commissions you to watch over that soul forever. You are eternally intertwined, connected.

A stronger bond than blood.

For Castiel his human, his soul, his otherworldly connection was to Samuel Winchester. The connection they share is unbreakable, even though it is. Broken, that is. Or that's how it's supposed to be.

He was also his first, only, and last.

Failure.

He'd failed Samuel in every way that a guardian could. He let evil grasp a tight hold on his soul, and drag him into their deepest depths.

He still couldn't let go though, even though his orders were to forget, to detach, and to accept his new duty. He couldn't let him go.

It was why he volunteered, and why he took the risk. Why he begged his father to let him take on this task; to pull Dean Winchester from perdition and place him back on earth.

To save Sam Winchester.

Because he couldn't let go.
