Author's note! Thank you sooo much for the review and all the alerts! XD They made me so happy and helped me pump out this chapter! So I've decided to center each chapter around a different character. It will be Cas, Dean, possibly another character if it helps the plot, or it'll just go back to Cas. I'm not sure if those actually make sense, but just go with me ok! Please enjoy and if you care please leave a review! XD

Castiel worked off his instinct and caught the falling male. He tilted his head to the side. He was unsure of what to do. It seemed that bringing him to Sam right now would be the wrong thing to do. With a confused stare he picked Dean up and cradled him to his chest. His wings spread out behind him and he took to the sky. A small frown made its way onto his face.

Dean had always had this light about him, one that radiate warmth to all those he cared for – until recently Castiel himself couldn't feel it. But now the warmth was so weak, as if his heart and mind had given up, but his soul still clung onto protecting people. "Dean please…. It…. Hurts to see you this way…" It was a whisper, but even if he yelled it he knew that Dean wouldn't hear him.

He landed in an old church that Dean had once shown him. Placing Dean gently on the cleanest bench he could he shook his head and flew away; only to rush back with some pillows and blankets. He didn't understand everything, but he knew humans couldn't be in the cold, and became uncomfortable easily.

Gently lifting Dean's head up head placed two large pillows. Then he wrapped Dean up, tucking him in like he had seen a mother do to a sick child. Castiel sat on the floor, unsure of what to do now. He had never had to take care of Dean, he left that to Sam. Jimmy's human heart made him feel pain, it beat painfully against his chest as he watched his human become paler.

His whole body began to shake and his eyes became blurry with liquid. He didn't know what was happening, all he knew is that it was connected to how weak Dean was becoming and how his warmth was slowly leaving him.

"Scary isn't it?" Castiel jumped up protectively, only to relax slightly when he noticed it was Anna. "How did you find us?" Anna smiled sadly. "I saw you flying." Castiel simply nodded. "Do… Do you know why I'm like this?" Anna nodded at Castiel's broken question. "It's called sadness, and fear. You fear that Dean will leave you. And you are full of sorrow because he might not be your human anymore." Castiel could only look at her with a confused tilt of the head and sorrow filled eyes.

"How do I save him?" His voice was so weak that Anna felt it as if it were a physical blow. He loved Dean. She thought Angels couldn't feel emotions. This time spent with Castiel proved her wrong. She walked towards them but stopped when Castiel was suddenly stationed between them with a glare pointed her way. "That, Castiel, is jealousy." Castiel almost stumbled. He didn't understand how it was all possible, but with a quick glance at Dean he decided it was because Dean was unlike any creature on this Earth.

"I know of a way, but-" Castiel cut her off. "What must I do." Anna shook her head. "You would have to share your grace with him. You would become a Halfling and the two of you would become mates. Obviously you would have to complete the bond by taking Dean."Castiel nodded. Anna threw her hands into the air – exasperated. "Just kiss him and force some of your grace into him. He will still be broken, it will be your job to nurse him back to health. You and I both know that what Dean has been through is more than any human should be capable of and _CASTIEL WAIT!"

She was too late, Castiel had already pressed his lips to Dean's and began to push his grace into the human. A glow began to emit from Castiel and soon it surrounded Dean and spread through the whole church. Anna had to close her eyes and turn away. She had never seen a light burn so fiercely.

The light finally faded and she turned to see Castiel fall to his knees. "Castiel you fool! I wasn't done-" She was cut off once again. "Hush. You'll wake Dean." He glared at her fiercely. "I still wasn't done explaining things. First off, because you've bonded you will have all the basic knowledge that Dean does, which means understanding emotions won't be so difficult. But now you're going to be extra possessive and territorial over Dean because he holds part of your soul and you his. Not to mention you'll be able to sense him – when he's hurt or happy, or even horny. You'll be connected to him no matter what."

Castiel nodded, he hadn't even noticed how easily it was to slide into these emotions that he suddenly understood. Anna tried to step closer and Castiel did a very impressive growl. Anna stopped mid-step. "Maybe I should come back later." Castiel sent her an exasperated look. She spread her wings and flew away.

He turned back to his mate and gently nuzzled his cheek, enjoying the way Dean's soul seemed to have began to fight against his heavy heart and mind. It pleased him further to notice that Dean's very soul was reaching out towards him for comfort.

Three days had passed with Castiel watching over Dean's still body, fetching food for himself and liquids to pour down Dean's throat. Castiel went on another food run, only to come back and notice Dean was no longer on his make-shift bed. Both anger and fear filled him as he searched frantically for his mate.

He threw the food to the side and began to search everywhere inside the church and realized that Dean might be in his car! He had brought it here because he thought it would make his mate happy, but he made sure not to leave any gas in it.

He ran to the car and felt himself give a sigh of relief. Dean was on the hood of his car, curled into a ball. Castiel wanted to punish Dean and teach him that mates shouldn't leave unless they were given permission, but decided against it. Dean was still hurt, and didn't even know of their new bond. So with silent movements Castiel got onto the hood with Dean and placed a hand on his head. Dean shot up, shock floating off of him in waves, until he noticed it was Castiel.

"Cas.." He muttered, before trying to sit up right. Castiel wrapped an arm around Dean and sat him up pulling him close. "Cas! What are you doing?" The half-angel just laughed, causing Dean to freeze with shock. "We have much to talk about. So please do not talk until I am done." Dean gave a hesitant nod. With that Castiel began to explain the past few days a very surprised Dean.

Yes Cas is going a bit –me man you woman- but I like to think top Cas Is kinda hot. Besides Cas is working off basic instinct. Yeah Den was trying to act like his old self, but that won't last long –Trust me! –wink wink nudge nudge- I use Castiel's name a lot - I'm going to work on that. Hope you enjoyed! PLEASE review! XD
