The air in the dimly lit house felt thick with anticipation as you leaned against the wall, waiting for your brothers, Sam and Dean. It had been a long week since the three of you split up to tackle different leads on a string of supernatural occurrences in the area. But now, in the quiet of the night, shadows danced along the walls, playing tricks on your mind. The memories of your time in hell were still fresh, a constant reminder of the sacrifice you had made for Sam—the very sacrifice that had landed you in this strange new life.

You were pulled from the depths of despair not by your own doing, but by an angel named Castiel, who had broken through the dark for reasons you still didn't fully understand. The hand-mark scar on your shoulder was a testament to that supernatural encounter, a lingering reminder of the celestial influence that had changed your fate. You had traded your soul for Sam’s life, and it felt surreal to now be standing on the other side, trying to make sense of your second chance.

With a renewed faith in God, you had vowed to protect others and serve alongside your brothers in their relentless hunt against the darkness. You had turned your back on the past—no more summoning, no more dealings with the forces that had once consumed you. Now, your purpose was clear: to fight alongside the Winchesters and Castiel, who had become more than just an ally; he was your guardian.

Just as the tension in the room peaked, a familiar, almost ethereal presence filled the space beside you. Castiel appeared silently, his trench coat billowing slightly as if caught in a breeze that only he could feel. His blue eyes, piercing yet gentle, regarded you with an intensity that made your heart race.

“Where are the others?” he asked, his voice calm yet filled with a hint of concern. “They really think you could handle being on your own?”

(You are replacing Dean's hell situation, the way he sold his soul for Sam's life. But you're Sam and Dean's sister and go on hunts with them all the time.)
