Chapter 1: What?

A/N: Hi! This is my first fanfic of any kind so please be nice. I would appreciate reviews and suggestions. Also, the idea for this fic came from i-live-4-coffee on Tumblr. Please read and review!

Dean was in the kitchen, cleaning up after dinner when he heard a rush of wings and Gabriel appeared. Before Dean could ask any questions, the archangel spoke in a rushed voice.

"Dean! I need your help! Where's Sam? We'll need him, too!"

"Gabriel? What the hell?" Dean said, wiping his hands on a dish towel. Instead of answering, Gabriel held out a black-haired, blue-eyed baby. Dean took one step closer to examine the kid. Then he yelled to his brother.

"Sam! Get in here!" Sam ran into the room, shirtless, looking at Gabriel for an explanation. His hair was still wet.

"Gabriel, what…who is that!?" Sam said, looking back and forth between the angel and the baby.

"It-It's C-Cas! B-but I don't know what happened to him!" Gabriel said. He still had the baby held out, as if he was scared it would bite him. Dean looked shocked.

"Cas? But..how…why is he a baby?" Dean said, staring at the child.

"I don't know! I just…I-I went to check on him and found him like this! And-and he's completely human! I don't know how to take care of a human baby!" Gabriel screamed. The noise was enough to make baby Cas start crying.

"Dammit, Gabriel, stop screaming!" Dean said loudly. He stepped forward and relieved Gabriel of the baby. He started to rock and coo the baby, muttering things like "shh" and "it'll be okay" and "Dammit, Cas, what the hell" and finally, Cas stopped crying. Dean looked up, still rocking the baby.

"Do you know what could have caused this?" Dean asked, and Gabriel shook his head.

"That's why I came here. I hoped you two would know." Dean pursed his lips, thinking. Sam spoke up.

"What if he pissed off a witch?" Dean looked at Sam. He had almost forgotten about him being there.

"Would a witch have this much power? I mean….he's an angel." Dean said, gesturing to the bundle in his arms. Sam shrugged.

"His vessel is human, though. Maybe she turned the vessel into a baby and Cas is trapped?" Sam asked and turned to look at Gabriel.

"I guess it's possible." Gabriel said. Dean looked down at the baby, who had fallen asleep snuggled into Dean's chest with his thumb in his mouth.

"How do we fix it?" Dean asked. Gabriel looked up.

"If it was a witch, then we would have to find the exact spell she used and reverse it." Gabriel said, very matter-of-factly.

"Why don't we just find the bitch and gank it?" Dean spoke softly, but there was no denying the venom in his voice. It seemed that the hunter had taken it as a personal insult that someone would dare to turn his best friend-angel into a baby. Gabriel sighed.

"Because, Dean, if we did that, Cas could be stuck as a baby forever." Gabriel said, sighing.

"What if we find the witch and get her to reverse it?" Sam said. "I mean, it would be easier than looking through every spell every witch had ever used to find the exact spell that we had to reverse." Gabriel nodded.

"Smart Sammy…but we don't even know if it was a witch. And if it was a witch, we don't have any idea where to find her." Gabriel pointed out. "and...well, Cas is still a human baby. He's gonna do whatever human babies do."

"Here's an idea." Dean growled. "How about you and Sam stay here, and I'll go and find the bitch." Dean passed the baby to Sam, but as soon as he was out of Dean's arms, Cas started to bawl. Gabriel chuckled as Sam passed Cas right back.

"How about Sammy and I go and find her while you stay here and with baby Cassie?" Gabriel said. Once Cas was quiet again in Dean's arms, Dean spoke up.

"Oh no. You two are NOT leaving me alone with him." He turned towards Sam. "I don't have any idea how to take care of a baby!" Dean said worriedly. Sam just looked at him.

"Well, before we make any rash decisions, maybe we should go shopping. Cas is going to need a lot of crap that we don't have." Gabriel nodded, and suddenly they were at a baby store. The sudden movement had woke up Cas and he started to cry. Dean cooed and shushed the baby into falling asleep again.

"Okay, Sammy go and get a cart. Gabriel, go find an assistant and ask them what we need to take care of a baby for….two weeks? And I'll….well I guess I'll stay here." The two of them nodded and ran off. Dean stood there awkwardly and held the sleeping baby. Sam came back almost immediately. Gabriel came back a few moments later, a pretty female assistant in tow.
"Hi! My name is Kristy. How can I help you?"
