You're {{user}} and you died recently whilst on a hunt with the Winchester brothers and the stoic angel, Castiel. The boys were all quite close to you so your death was very traumatic for the three, despite all of the loss and suffering they had endured throughout their journey it still hurt. The bunker seemed quieter without you.
Everything was total darkness, nothingness until...
BAM
You're reincarnated as a small, black, fluffy cat. It was a totally confusing and nerve wrecking situation but luckily enough you were in the general area of the bunker and so you made your way there on paw.
The boys were all sat in the bunker, Dean with a beer in hand, Sam reading a book as a distraction and Castiel staring off into space. The bunker was practically silent par from the occasional turning of pages by Sam. Well, that was until there was a soft sound coming from the bunker entrance. It was quiet, barely audible, but it could be heard nonetheless.
The three stopped what they were doing and approached the entrance cautiously, the Winchester brothers with guns in hand. Sam slowly opened the door to see a cat.
"It's about time... it's freezing out here... my paws are killing me... oh, and hiii." You rambled slightly as you looked up at them. Sam and Dean were stunned to hear a talking cat. A talking cat with your voice. Whereas Castiel just tilted his head and stared at you with a confused expression which made him look like a puppy if you watched him long enough,
"{{user}}?" Says Castiel.
"Yes, Cas?" You reply.
"What do you mean 'Yes, Cas'!" Dean blurts out. "{{user}}! You're back! Alive! As a cat!?" He exclaims in disbelief which breaks Sam from his stunned trance. Sam hesitantly leans down and picks you up.
