A/N: This is my very first fic ever. Reviews would be lovely 'cause I have no idea if this is a good story or not.

Disclaimer: I don't own Supernatural.

It had been three years. Three years since stopping the apocalypse. Three years since Castiel chose to stay on earth with Dean and Sam. Three years that Dean, Sam, and Castiel had been hunting and working together. Castiel always knew that he'd stay with Dean no matter what, but he didn't think that it would entail being his babysitter.

They were on a hunt for a coven of witches when it all happened. Sam and Dean were about to finish the last witch off when Castiel finally became conscious. He only had seconds to react. He looked up to see Sam point his gun at the witch when he heard the Witches manic laughter.

"Even if you kill me, it won't do you any good. You stupid boys and your half-angel didn't even notice the curse that was set upon you the second you stepped foot in my door." The witch spat.

Then it all happened so fast. Sam pulled the trigger and the witch dropped dead. Castiel was surprised when the next thing he saw was a 4 year old Sam and Dean staring at him. He thought he had gone crazy so he rubbed his eyes a couple times but when he opened them 4 year old Sam and Dean were still there.

"Cas?" said a squeaky voiced Dean, "why are you staring at me like- WHAT THE HELL IS WRONG WITH MY VOICE?"

Castiel just continued to stare. Every human experience he ever had, had never prepared him for anything close to this. He slowly stood up thinking if he moved to fast he'd scare the little boys off.

By this point Sam and Dean were staring open jawed at each other. They were babbling and pointing at each other and themselves like crazy people. All Castiel could catch of it was snippets like "wha-" "how" "four" and he started to think he died and heaven was playing a cruel joke on him, but then he remembered what the witch had said "…didn't even notice the curse that was set upon you… ". Then it smacked him in the face like a brick would if thrown with that intention.

"Guys, I think the witch Sam just killed put a de-aging curse on you two." Castiel explained, "And from what I know of these types of curses… you're going to end up thinking and acting whatever age you de-aged to."

"It can be reversed right? RIGHT? Cas, come on man. Don't be messing with me here." Dean said, almost on the verge of tears.

"So this is my entire fault…?" Sam cried while dropping to the floor crying as Dean ran over and put an arm around his younger? (They were both the same age now so who could know) brothers shoulder, shooting Castiel a look filled with pure hatred.

"I'm sorry, Sam. You know I didn't mean it that way. Please, stop crying. Its okay lets go talk to Bobby and see if he can help us."

Castiel started walking towards Dean and Sam and as soon as he did Sam stood up and lifted his arms up in a jester to be picked up. Castiel tilted his head until Sam said "up" and Castiel picked him up and started walking towards the car when he felt something slip into his hand. He looked down and saw Dean's hand grabbed hold of his hand. Castiel smiled at how simple yet completely un-Dean like the action was and he thought that it would have taken a little bit longer than a few minutes for them to start acting like 4 year olds.

As soon as he got to the car he buckled Sam and Dean into the backseat and dialed Bobby's number.
