Supernatural Sister Imagines

Imagine #104: The Rest of My Life

Imagine: You and Castiel talk late one night while Sam and Dean are asleep.

Age: 16

Warnings: sweetness and goodness and otherness.

A/N: This ones short because the only real reason I wrote it was because of the dialogue at the end.

     You cracked open a e/c eye, the dark that greeted you broken only by the moon in the window, everything cast in a soft white glow as you breathed a sigh through your nose, rubbing your forehead in annoyance. Many failed attempts at sleeping had left you restless, and your legs itched to move.

     Grunting quietly, you rolled to find yourself face-to-face with Dean, sleeping beside you. You allowed yourself a small smile as your hand drifted up to ghost over his cheek, the touch barely there as you stared at your brother in the dark. You carded your fingers through his hair a few times, his eyelashes fluttering as the pad of your finger grazed them.

     He let out a long sigh and you let go of him, leaning forward and pressing your lips gently to his cheek, holding them there a few seconds before releasing him and throwing the covers off of you, standing and stretching. You crossed the motel room to Sam's bed, kissing his cheek as well.

     You threw on a jacket and pulled a pair of boots over your leggings, grabbing the keys from the table and opening the door. You winced as it creaked, glancing back at your brothers, but Dean simply snorted, Sam rolling onto his stomach. You stepped out the door and quietly closed it behind you, shoving your hands in your pockets as you took off down the hall.

     You found the stairs and climbed all the way up, picking the maintenance lock and stepping out onto the roof of the motel. You padded out to the edge and sat down, crossing your legs and staring out at the lights around you, your hair blowing gently in the breeze.

     You began to shiver after a few minutes of sitting, but you did not bother to move, simply embraced the cold and continued to gaze out over the town, the lights reflecting off your eyes beautifully.

     It wasn't long before you heard a flutter of wings, glancing to your side as Cas silently removed his trenchcoat and hung it over your shoulders, sitting down beside you, your shoulders pressed together. He didn't say anything, and for a long time, neither did you.

     "Cas," Your voice broke the silence like a ball breaks a mirror, "are there guardian angels?"

     Cas was quiet a moment. "Yes. Everyone human is assigned one, but thanks to Lucifer, and demons, most of them are dead."

     "Do I have one?" You asked, leaning against the angel and allowing your legs to hand over the edge of the building beside his.

     Cas nodded. "You do."

     "Is it you?"

     "--It is."

     "What do guardian angels do?" You asked, your voice a soft murmur as you watched a car roll by lazily, far below you.

     "Lead their human to Heaven, when they die," Cas explained, "Our job is to be loyal to our human unconditionally, and to take care of them, but all whilst never being seen. The reason you and I communicate, is because you're a hunter, and because--" Cas trailed off, and you glanced up at him.

     You tilted your head to the side. "Because of what?"

     "Because I fell for you," He said, "I fell for your brothers. You weren't ever supposed to meet me, but you did, because I love you. To me, you're not just the human assigned to me. You're my sister as much as any other angel in my garrison."

     You went quiet a moment, your gaze returning to the town as your head fell to his shoulder. "Angels are immortal, right? Or at least, you don't die unless an angel blade kills you."

     Cas nodded. "Yes. I've been around for thousands of years, and I'll be around for thousands more."

     "So, after I die, do you get a new human assigned to you?" You asked, fiddling with your fingers.

     Cas pressed his lips together, sighing. "We're supposed to, but-- after you die, I won't take another."

     "Why not?"

     "None of them will be the same."

     A smile crossed your lips. "I'm glad you're my guardian angel, Cas."

     Cas's cheek fell to your head and you could tell he was smiling back. "Me too, Y/n."

     The two of you fell silent and you looked once more over the town, watching the few stragglers still out this late as they walked down the sidewalks. A lady with a waitress uniform on, her face exhausted as she padded along on heeled feet, her steps wobbly. A man who stumbled and tripped over every crack, a bottle of whiskey in his hand as he hiccuped his way home.

     And it was different. There was something different in the air as you sat there with your angel. Something surreal.

    "Cas?"

    "Hmm?" He hummed.

    You sat up and looked at him. "You'll love me for the rest of my life, right?"

    He glanced at you, his face calm. "No."

    You raised an eyebrow, but before you could say anything, he took your chin gently in his hand and kissed your forehead, something he'd never done before, and suddenly you were smiling like an idiot.

     "I'll love you for the rest of mine."
