Imagine: Cas has to babysit you.

You woke up when you heard movement outside your room. Your eyes snapped open, and you lightly jumped out of your bed, and excitedly ran towards the noise.

You saw Dean walking down the hallway, towards the kitchen, and you sprinted towards him. Your feet made a light thumping sound against the floor, and Dean turned around as he heard you.

A smile spread over his face, and he bent down slightly and opened his arms. You launched yourself into them, and he picked you up and spun you around.

"Morning, kiddo." He said, pressing a kiss to your forehead.

"Morning!" You exclaimed, kissing his cheek.
With one hand, Dean held you against his hip and carried you to the kitchen and placed you on a chair.

"You want cereal?" He asked, and you nodded quickly.

Dean grabbed your favorite sugary cereal, poured it into a bowl, then added milk and placed it in front of you. You scooped up a giant spoonfull, and shoved it into your mouth.

"Did you sleep well?" Dean asked, sitting next to you with a hot cup of coffee in his hands.

"Mhm." You confirmed, mouth full of food.
Dean smiled at you, then took a sip of his drink.

After a few minutes Sam entered the room, and you smiled widely at him.

"Sammy!" You announced, pushing your cereal away and holding your arms out to him.

Laughing slightly, Sam easily picked you up and spun you around before pulling you into a hug. You kissed his cheek, then he put you down and poured himself a cup of coffee.

"Sam and I are going out today, okay?" Dean said.

You pouted, not wanting them to leave you, but nodded nonetheless.

"And Cas is gonna come hang out with you." Sam added, sitting by your side.

"Cas!" You shouted happily, a smile brightening your face.

At the mention of his name, the angel appeared in the room. He moved to your side and pressed a kiss to your forehead before standing tall again.

"Hello." He greeted your brothers.

"Now that you're here, I guess we should go." Dean sighed, getting up.

You watched your brothers leave the room, and looked to Cas.

"Hi!" You exclaimed.

"How are you today?" Cas asked, taking Dean's seat near you.

"Good." You answered. "How are you?" You replied, trying to make your tone mature and businesslike.

Castiel offered you a smile. "I'm doing well."

"Are Sam and Dean going to save the day again?" You asked, tilting your head at the angel.

Cas couldn't stop his smile from growing in adoration and amusement. "Why would you ask that?"

"Because...." You started, but trailed off.

You looked around the room before leaning towards Cas. "Because Sam and Dean are superheroes." You whispered. You didn't know Sam and Dean were standing in the doorway. They were about to say goodbye, only to hear you talking to Cas.

"Well..." Cas started. "Don't tell them I told you, but yes. They're going to save the day."

"I knew it!" You exclaimed. "I wanna be just like them when I'm older." You stated, with such conviction, that nobody would ever question you on it.

Castiel glanced up at Sam and Dean, then back at you.

"I know you will." He replied.

Then Sam and Dean decided to make themselves known. Your brothers walked into the room, and wrapped you in a giant hug, sandwiching you between them.

"We'll be back tonight." Dean promised, kissing your cheek, which Sam did next.

They placed you back on your chair, then walked out of the bunker, leaving you with Castiel.

Cas took your now empty bowl, and placed it in the sink. You jumped up from your chair, and ran to Cas side. Once he let his arm drop to where you could reach, you grabbed it and started pulling him to your room.

Cas sat on your bed, and watched as you went through your impressive collection of toys. You finally returned to his side with a Barbie and a Batman action figure.

"You can be Barbie." You said, handing him the doll.

"I think my voice would suit Batman better." He argued.

"But I'm Batman!" You exclaimed, trying to make your voice deep.

Castiel laughed in amusement, and shrugged his shoulders. He could never argue with you for long. "Hi Batman!" Cas said, moving the Barbie doll slightly, and making his voice extremely high pitched.

"Barbie. Prepare for justice!" You shouted, then hit the Barbie doll with Batman.

"Ahhh!" Cas exclaimed, and threw Barbie in the air, eliciting a string of giggles from you.

"Now, Barbie-" You started, moving your toy towards Cas'.

"Wait, wait." Cas said, his voice normal. He looked up, his eyes getting a faraway look.

"Your brothers are calling me." He told you, standing up.

"I'll be right back." He assured you before disappearing.

You sat by yourself for a moment, then heard movement coming from outside your room.

Assuming Cas had returned, you jumped to your feet and opened your door. But it wasn't Cas. You barely had time to look at the intruder's black eyes before a bag was thrust over your head, engulfing you in fear and darkness.

——————————

You passed out at some point, probably from fear, and when you finally opened your eyes, you were in an unfamiliar room.

The room was large and dark, except for a small line of light coming through a dirty window. Boxes were stacked along the wall, and a few other chairs stood across from you.
You were tied to your own chair. A single, thick rope was wrapped around your body, holding your arms by your sides. You had enough room to breath, but not enough to get your arms out.

"Sam? Dean? Cas?" You called out, voice frail and shaking. Tears started streaming down your face.

Then a door at the far end of the room opened, and lights flooded the area. You winced from the sudden light, and once you were used to it, looked at the person who had walked in.

He wasn't taller than Sam or Dean, but still tall nonetheless. He had broad shoulders and a knife in his left hand. A tough beard of brown hair hung on his chin, and had shaggy hair of the same color on his head. And his eyes were black.

"Are you scared?" He asked. His deep voice resonated through the room.

You could only nod in reply.

"Good." He commented, kneeling in front of you. "You're brothers are coming for you right now. And when they get here, I'm going to kill them." He said.

You started crying again, unable to stop yourself.

"You can't! They're superheroes!" You shouted.

Then, to emphasize your point, you kicked your legs out, and stuck the man right in the chest, making him fall back.

"You little....." He snarled, getting to his feet. He gripped the knife tightly, towering over you, prepared to make you pay.

But then Sam was on him. You hadn't even noticed your brothers sneak into the room.

Your eyes widened as Sam stabbed the man in the chest, and his eyes flashed brightly before he died.

You looked up and saw Dean running into the room, a few other men chasing him. Sam turned to help Dean, and soon all the men were dead on the ground.

Cas had appeared behind you at some point, and easily untied you. You jumped into Cas' arms, burying your face into the crook of Cas' neck and crying.

Castiel held you tightly, guilt and anger welling up inside him. He watched as Sam and Dean finished off the last of the demons, then walked up to them.

"I'm so sorry." He said for the hundredth time.

"It's okay." Sam said, as Dean took you from the angel's arm.

You held onto Dean tightly, as if your life depended on it, and he rubbed your back while humming Metallica softly.

"Thanks Cas." You mumbled, moving your head away from Dean so you could look at the angel.

"You're a superhero too."

Cas felt his throat tighten, and offered you a small smile before disappearing. Dean passed you to Sam, and you wrapped your arms around his neck before resting your head on his shoulder.

Your brothers took you to the Impala, and Dean jumped in the driver's seat. Sam got in the back with you, and held you as Dean drove home. You quickly fell asleep after all that happened, too emotionally exhausted to keep your eyes open.
