Dean was getting tired his little boy moving slower as the smoke circles around him, his lungs burning as he choked. He just wanted to sleep for a little, Dean heard his father calling for him in the background Sammy crying. Then there was a sharp pain in his shoulder as something started to drag his limp body out to safety.

John was holding Sam to his chest standing as close to the house as he could calling Deans name. His heart pounding in his chest thoughts of losing his son along with Mary Plaguing his mind, but then he saw something moving in the fire. "Dean!" he shouted as a dog walked out of the fire pulling Dean out with him.

That's how it started John kept the dog which turned out to be a Grey Wolf puppy. John loved the wolf for saving his son, John also let Dean name him when he got back from the hospital and right away Dean said "Castiel." John then started going after what killed his wife, and anything else that threatened his family.

Its been six years since that night and Dean was watching Sam as he played on the jungle gym in the park near the motel. Castiel was next to Dean sitting on the floor, his bright blue eyes watching Sam as he ran around. Castiel then saw something out of the corner of his eye, his head snapped around. He stood sniffing in that direction when he saw a man with black eyes start walking toward them.

Castiel started to growl low his teeth shown as warning. Dean looked down at him "What is it boy?" he ask looking in the direction Cas was, the only thing he saw was some guy walking toward him. Dean stood standing next to Cas, as the man got closer Castiel started barking ears bent back ready to attack.

The mans smile was sly and evil as his eyes turned black, Dean gasped and bolted for Sam. "Sam!" he shouted, Sam looked toward him frowning at how his brother looked. Dean grabbed Sam's hand pulling him away "We're leaving" he said firmly jogging toward the motel Sam trying to keep up looking for Cas.

"Dean... where's Cas?" he asked and Dean stopped Dead looking toward the bench he was sitting at. Castiel was in the same spot growling at the demon in front of him.

Dean stuck two fingers in his mouth and whistled as loud as he could "Cas" he yelled. Castiel slowly stood straight and slowly backed away from him. Once he thought he was far enough he turn and started to run but something snagged his back leg and pulled him back. Dean heard Cas cry out in pain, "Castiel!" Dan shouted "Stay here" he told Sam before running to Castiel's side.

Castiel bit whatever unseen force was behind him as Dean got thrown back by the demon, "Well well well, what have we here?" he said looking to Cas "no regular wolf would be able to harm or even see a hell hound" he said grabbing Dean by the throat holding him in the air. Castiel barked deep and loud at him ears flattened.

"Put him down" a deep gravely voice said.

The demon took a step back "What God has to much free time" he laughed.

"Dean!" John yelled causing the demons head to snap around.

For a split second Castiels eyes narrowed before he launched forward his jaw closing around the demons throat. Dean fell to the ground choking and grasping at his throat. John stood frozen never has he seen Castiel attack someone like this. Castiel jerked his head ripping flesh, blood soaking his fur the demon push at him. Castiels jaws locked ripping more and more of his throat out before back smoke flowed out of the man mouth. Once the man went limp Castiel pulled away stepping back the tasted of blood covering his mouth, he walked away from the body his stomach aching from the taste of human blood. Unable to hold back he threw up, his back arched as his body shook all four legs going weak.

John rushed over to Dean checking his son "Dean, Dean look at me are you alright?" he said holding his son close.

"Dad I'm fine okay" he said reassuring his dad then he sat up "Sammy!" he said looking to were he left Sam. Sam was turned around looking towards the motel. He sighed in relief looking back to his father who pulled him into a hug. Castiel slowly walked over to them just reaching Johns side before clasping with a whine.

John turned to the sound to find Castiel covered in blood, "Dean go get Sam and get in the car" he said watching as Dean ran and got his brother. John then picked up Castiel and Carefully put him in the backseat. "Dean you seat in the back with Cas. Sam up front with me" he said.

~o~

Castiel slowly woke when he felt something warm slowly cover the bottom half of his body, he flinch a little before opening his eyes to find John lowering him down into the bathtub. "Hey Cas it's okay" he said pouring water over his back, Castiel shivered a little at the feeling. Dean walked into the bathroom with the pet soap and handed it to his father before kneeling next to the tub.

Dean ran his hand through Cas' wet fur as John started to wash the blood out of his fur. Castiel looking up so John could get him clean quicker, Dean smiled scratching his head. Castiel started wagging his tail hitting Dean with water causing the boy to laugh. John smiled he almost forgot what Deans laugh sounded like.

John rinsed Cas' fur watching as it turned from red to white "Looks like your all done buddy" John said. Castiel looked at him and then started to pant showing his red mouth. "Oh okay Dean go get his tooth brush" he said. After a moment Dean came back handing his dad the tooth brush.

After Castiel was fully clean John tucked Dean in for bed, Sam already silently snoring in the other bed. Once John left Dean sat up and looked at Cas on the floor "Cas" he said watching as the wolf looked up at him. Dean patted the bed "Come on boy up here come on" he said, Castiel jumped up on the bed laying down in Deans lap. Dean scratch his head and behind his ear "Cas?" he said "Was that you who told the demon to put me down?" he asked and Castiels head snapped around staring at him. "It was wasn't it" he said smiling "This is awesome am I like a superhero or something?" he said.

"Dean please be realistic" Castiel said.

Dean's mouth hung open in shock "Okay so if I don't have superpowers how can I hear you?" he asked and Castiel sat up placing his paw on Deans shoulder. Dean looked at his shoulder lifting his sleeve up to find a scar from were Castiel bit him to save him from the fire. Dean then looked to Cas and nodded"I get it.. I think" he said.

"I am a surprised as you Dean" he said "I was not expecting you to be able to hear me" he said tilting his head.

Dean smiled cupping the dogs head with both hands "Well I'm glad I can talk to you" he said laying back down yawning.

"Dean you mustn't tell anyone about this" he said knowing Dean wouldn't tell his father with the thought he might kill Cas thinking he was a monster. Castiel yawned himself before placing his head on his paws and closing his eyes.

~o~

Castiel was the first one up as usual walking out to where John was a sleep, slowly walking over to the small kitchen area knowing the coffee bolt was prepared stood on his back legs pressing the button to turn it on. He then went back into the boys room carefully jumping up on Deans bed walking up to where his head was. He stood there for a moment watching how peaceful he looked, his thoughts were interrupted by the coffee machine beeping to signal it was finished. Castiel then started to lick at Deans face waking the boy up.

"Oh gross come on Cas" he said laughing a wiping at his face. Castiel panted wagging his tail in excitement, he then jumped off Deans bed a ran to Sam's waking the smaller boy in the same way. Once the boys were awake they went to John and all jumped on the bed waking him up with laughter.

Castiel stood back watching the family have one of those rare moments of happiness were John was laughing and smiling with his boys. John notice Castiels dazed look and pause looking to the dog. "Come on buy come here" he said and Castiel jump up on the bed allowing Sam to wrap him in a hug as Dean and John scratched his head. John smiled at him and Castiel jumped on him and started licking his face, John laughed pushing Cas off and getting up "Alright who wants breakfast?" he asked and both boy yell "Me!" and ran to the table.

John gave them their cereal then put a raw steak on a plate for Cas placing it in front of him. Castiel looked down at the meat knowing it was a reward for saving Dean since it was bigger than usual, Castiels stomach flipped at the smell and he pushed it away back to John. Dean notice and got up kneeling next to Cas petting him slowly, "What the matter Cas?" Dean asked.

Castiels body clenched as the taste of human blood entered his mouth through memory, Castiel turned away his legs weak as he tried to walk away unable to stand. John caught him just as he fell, Dean stood worried "Dad whats wrong with him?" he asked.

John looked down at the wolf in his arms "I'm not sure Dean" he said carefully placing Cas on his bed. Dean hung his head sorrow filling his heart, his beat friend was sick and he didn't no why.
