Castiel X reader--Until Death Do us Part

Imagine human!Cas dying and you promising to stay with him until the end.

Trigger warnings: Death of loved ones, blood, wounds, basically what you'd expect in a story about someone dying.

You stir your morning coffee idly, letting the spoon clink against the sides. The bunker is near silent, and it's beginning to get to you. Sam and Dean have been searching for Castiel ever since the angels fell from heaven, but you haven't heard back for days. You sit in the vast open area, alone. It feels like there is a hole in the world without connection to Sam, Dean, or Cas.

You stand up and lumber toward the library, dropping your coffee in shock when you step inside. In the middle of the room stands Meg, barely holding up a limp Castiel under his arms. The two of them are covered in deep cuts as bruises. Ignoring the coffee on the ground, you race to them and take Cas out of Meg's arms.

"What happened? Is he ok?" You lower him to the floor and stroke the side of his dirt-coated face. His eyes are softly closed, but look bruised.

"Oh, I'm fine thanks for asking," she says sarcastically.

"Meg! At least you're conscious! What happened?"

"Cas is human and we got attacked. So I brought him here."

"What? How is he human--Never mind. Just stay here and call me if he wakes up," you order, going into action mode. You dash back to the kitchen, leaping over the spilled coffee on the way. In a drawer, you find a first aid kit and bandages. Hydrogen peroxide is in the bathroom, so you grab that too.

You pull out your phone and dial Sam as you sprint back into the library. The phone goes straight to voicemail.

"Sam, I don't know where you are or how fast you can get here, but Cas is here. And he's hurt. Really badly. I need you back ASAP."

You send the voicemail, entering the library and finding Cas lying all alone in a pool of his own blood.

"Damnit, Meg." His head lolls in your arm when you lift him. His skin is cold, but you can still find a pulse beneath it.

You absently talk to Castiel aloud as you tend to the damage. "Ok, you're going to be ok. I just need to get a look at your wounds."

Button by button, you pull apart his shirt to reveal more slashes, oozing blood. You thread the needle from the first aid kit with shaking hands before soaking a cloth in the peroxide for his wounds.

"This is gonna hurt a little."

When the liquid touches his wounds, he flinches visibly and you stroke his cheek as you apply it.

"I know, I know. Just hold on a minute."

You take the bandages and use it to wrap tightly around the largest wound on his side to stanch the blood flow. Then, you find the threaded needle in one hand and hold a wound on his chest with the other.

"Ok, Cas. I need you to hold still. This is not going to be pleasant."

Taking a deep breath for yourself and Cas, you insert the needle into his skin.

He moans and shifts a little.

You don't stop. You can't. As you finish the stitch, you croon, "I'm sorry. I know it hurts. Just stay still."

With each stitch, his eyes screw tighter and his face scrunches up. You knot the thread at the end of the wound and break it with your teeth. His body instantly relaxes.
