Cas' POV

I watched as Dean shifted his new wings uncomfortably as he tried to settle down to sleep, after a couple seconds I laid a hand on one of the wings making him stop, I carefully adjusted them so they would be comfortable for him and he yawned, falling asleep. I kept a hand on his wings, softly running my fingers through them, drawing out a gently purr from Dean. I took a deep breath and ran my hand through my hair, I felt terrible for Dean having to have grown the wings, it shouldn't have happened but my grace, the power of Dean's soul, and the power of the angel tablet made them grow. I couldn't stop feeling guilty but aside from the initial anger Dean had taken things remarkably well, I was very surprised and if not a little worried because I knew Dean tended to internalize things. A few hours later Deans wings shifted a little in his sleep, and then they curled tighter around him and I could tell by the way they had gotten closer to him he was having a bad dream. I gently rubbed the space between Dean's wings and he settled down some but soon his fists had clenched and he was whimpering softly, I touched his forehead going into his mind, I didn't like doing it very often. His mind was in turmoil and when I found the dream he was having I realized why he was dreaming of me leaving him and then something happening to Sam. I pulled out of his mind and then stroked his hair softly, eventually he suddenly sat up his wings flaring out with fear and he cried my name. I slowly stood up and got in front of him, he was gripping the bed sheets roughly and panting hard, with a tear rolling down his cheek. I kneeled in front of him and took his hand, he flinched at first before actually looking at me, "Hey, it's okay Dean"

Dean suddenly wrapped his arms around me and hugged me tightly, at first I was confused but I relaxed and wrapped my arms around him tightly, softly stroking a hand over his back. He was still breathing hard and his grip was tight. I softly whispered, "It's okay Dean, I am right here okay"

Dean took a long shakey breath before finally saying, "Promise you won't ever leave."

I softly kissed his head and nodded, "I promise Dean. I will always be with you okay."

Dean buried his nose into my neck, he was still breathing hard but his wings were folded against his back again, so I knew he had calmed down some. Finally, he pulled away from me and he smiled a little, and I could tell he was going to say something so I waited patiently for him to talk. "I sh..should not have asked y..you that Cas… I had no right…"

I softly took his hand and smiled, "Dean I agreed. I agreed because I no longer find solace in Heaven, and when I am away from you I do not like it. I like being around you Dean and I promise I will always be here."

Dean nodded a little but I could tell by his wings that he was still insecure, they were drawn in close to him in a protective manner so I took his hand, Dean noticed I was looking at his wings and his eyes met mine, "Cas you said you could tell I had feelings for you because of my wings. I don't understand how… Can you… explain it to me.."

I nodded softly, "Of course Dean. Depending on different emotions wings do different things. When you are scared they flare out and puff up, like when you woke up from your nightmare. When you… look at someone you love, depending on that angel's status your wings will show dominance or submissive-"

Before I could continue Dean interrupted, "Wait which one did mine show…"

I sighed hoping he wouldn't ask this but at the same time, I should have known better, "Well I am an angel of higher status so your wings became submissive… they sort of lowered and flattened out some…" Dean started to say something but I quickly interrupted, "When you are feeling insecure your wings will pull in closer to your body to protect you… Like they have because you are worried I am going to leave…"

Dean blushed deeply and looked down, "I… I can't help it Cas… everything good I get fucking leaves…"

I softly cupped his cheek and kissed him slowly before pulling away, "I know Dean. I am here, though, and I will stay here okay, I promise."

Dean took a deep breath and nodded, his wings were still close to his body but they weren't as close so I knew he somewhat believed me. "I didn't notice anything about your wings when I was…"

I smiled a little, "I have better control over my wings, I have had a long time to learn how to control them." Dean sighed and then ran his hands through his hair, his wings were slightly puffed up so I could tell he was nervous again, "Talk to me, Dean. What's wrong?"

Dean sighed again, "It's just… I hate not knowing what this is going to mean… I mean am I going to be an angel… will I be able to hide them like you can…? I just… it is fucking frustrating Cas."

I softly took Dean's hand, "Close your eyes Dean let me sense please…."

Dean bit his lip and took a deep breath before closing his eyes and nodding, I touched the somewhat healed burn mark on Dean's shoulder, making Dean gasp loudly. I closed my eyes and figured out what was going on with Dean. His soul was becoming more like Grace, telling me that he was becoming more like an angel, even though his soul was becoming more like Grace I could still feel access to the power of Dean's soul if I needed it. Slowly I pulled my hand off the burn mark on his arm, I waited for a moment making Dean look at me, "So… Any ideas what's going on."

I nodded a little, "From what I can sense… your soul is turning into Grace… with the power of the angel tablet boosting it… this shouldn't be happening and I wish I could explain why it was happening…"

I suddenly felt a surge of power enter the room and turned to see Chuck the Prophet, but with the surge of power, I could tell it was definitely not Chuck, at first thought maybe it was an archangel but Lucifer and Michael were both in the cage, Gabriel was Dead and so was Raphael. The power radiating off this thing was definitely heavenly, suddenly it hit me and I widened my eyes, Dean must have known I had figured out who it really was because he looked at me his eyes asking me who. God nodded gently to me, "Hello Castiel," I wanted to ask so many questions but I couldn't force myself to talk. Finally, he looked at Dean and nodded, "Hello Dean, it is good to see you are finally gaining your grace."

Dean's face pinched with confusion, "What the hell are you talking about. And Chuck is Dead so who the hell are you."

I heard the anger laced in Dean's voice and I wanted to stop him but I was in shock. God smiled a little, "Well technically Chuck was never alive. I have always been Chuck."

My brows pinched together and I tilted my head, finally making myself talk, "That is impossible I would have felt you."

God looked at me, "Not if I didn't want you to Castiel you should know that. And before you bring up the amulet Dean wore I had turned it off. I needed to catch the attention of Sam and Dean, see what was happening. I also needed to see Dean, see if your grace was going to bond with his soul and how long it would take."

Dean seemed to realize who Chuck really was now and his eyes widened with anger, "You-"

Before Dean could say anything else he was no longer able to talk, I knew my Father was keeping him quiet, after a few seconds Dean settled down some but his wings were puffed up and pulled tightly against him, I didn't have to look at his wings to know how angry he was. God sighed, "First of all please call me Chuck, Castiel you may call me Father but I really have come to prefer Chuck. I know you both have a lot of questions but the ones I came to answer were about Dean. Dean's soul was built specifically to eventually become grace when you put your piece of grace inside his soul. It was meant to happen. I wanted to see if it would work if a human soul could turn into Grace. I built the both of you by hand, Castiel was meant to pull you from perdition, Dean you were meant to be the righteous man, the one who breaks the first seal." I saw Dean flinch at that, I knew he still harbored guilt over that. "It was never going to be your father, as Alistair had so incorrectly assumed, it was meant to be you. There was initially a tiny hole in your soul, imperceptible to angels and demons, but when Alistair tortured you he made that hole bigger. Just big enough so Cas would need to fix it with a piece of his Grace when he was rebuilding you. I wasn't sure how long the process for your soul to turn into Grace would take but I had wanted an angel, who had grown up on Earth, to be able to care about the Earth and its inhabitants in a way no other angel ever could. Cas was built so he could care about the humans and eventually come to doubt me, doubt Heaven but only after he had pulled you from Hell. Many of Castiel's brothers say that Too much Heart is Castiel's problem, but they are all wrong. It was his purpose."

I stared at him with shock and awe, I could feel the despair and anger radiating off Dean. His wings weren't showing it and I realized how tense his body was so I knew Chuck was no longer allowing him to move, but he did allow him to speak, finally Dean said, "You experimented on me! You wanted the fucking Apocalypse to happen?!"

Chuck shook his head, "Not at all, I was hoping you would stop it. That is why I became Chuck, so I could help you stop it and you did."

"What about Ellen and Jo! We took them to try and kill Lucifer and they DIED! You could have stopped that! You could have prevented that! THEY WERE GOOD PEOPLE!" I saw the anger and hate in Dean's eyes, but most of all I saw the despair.

Ignoring Chuck momentarily I turned to Dean and stood in front of him, it took a few seconds for his eyes to shift to me and when they did I saw the tear roll down his cheek, "Dean…"

A few seconds later Chuck spoke, "Ellen and Jo Harvelle, they were wonderful people, I know that, its why I made sure to reunite them with the man your father got killed."

Dean tensed up, and part of me was angry at my Father for bringing up such a sensitive subject, "I… They didn't deserve to go like that…"

Chuck softly sighed, "It was how they were meant to go Dean."

Dean closed his eyes tightly, and I noticed his body had loosened his wings wrapping around him more, I could tell he was giving up and he was upset. I softly rubbed his back, "So what does that mean… I get it I'm turning into an angel but why and what am I supposed to do…"

Chuck sighed, "I want you to train with Castiel, to learn how to use your newfound grace. Flying, going to Heaven, healing, smiting. I know it will take time for you to learn how to use it, once you have learned that I will return."

Before Dean or I could say anything else he disappeared and I felt my whole body sort of deflate as I lost the tension. Finally, Dean looked at me, "I… what the hell! He fucking…. Son of a bitch…"

I took a deep breath, "I have to teach you how to use your powers…. If you want me to I can ask another angel."

Dean laughed and shook his head, "Cas I definitely don't one of those dickbags to teach me. I want it to be you alright."

I blushed a little and looked down, "I just wanted to make sure…"

Dean smiles and nodded, "I'm not the only insecure one here Cas. I love you and if anyone is going to train me I want it to be you okay."

I nodded, "Do you want to start…?"

Dean hesitated then nodded, "Yeah sure. Do you want to go to the gym?"

I nod, "It will work, for now, I should make sure Sam nor Kevin come in because we may be tapping into our grace so I do not wish for them to get hurt."

Dean nodded a little, "Right. Okay, I will put some shorts on and meet you there."

I smiled then got up to talk to Sam and Kevin, Sam was in the kitchen cooking himself something for lunch and I cleared my throat gently letting my presence be known. Sam turned around and nodded, "Hey Cas, How is Dean doing with wings?"

"Well, he has actually adjusted much quicker than it took some people… Um… but uh… well, my Father appeared to us… and apparently, Dean is essentially an angel… um… and he wants me to train Dean on how to use his wings and his grace so I wanted to tell you to stay out of the gym because we may be using our grace… also keep Kevin out as well." I said and then turned to leave.

Sam stood there shocked for a few seconds before noticing I was going to leave and he stopped me with a silent question, "You said Gabriel was the only Archangel to find his soul… do you know…"

I turned around to see Sam standing there looking at me, I could see the pain and loss of Gabriel, and I wondered if they had been in a relationship. "That you were his soul. Yes, I could see it after you and Dean were first made aware of Gabriel not being a trickster but an Archangel. Did you know?"

Sam nodded just slightly before looking down at his hands, "Gabe and I were in a relationship when he… uh… yeah."

I nodded and laid my hand on his shoulder gently, "It's okay Sam. I apologize for bringing it to attention. Anyways I should go before Dean comes looking for me like I said just keep out of the gym."

Sam returned to cooking his breakfast and I disappeared, then reappeared in the bunker's gymnasium. It didn't have much equipment, but the floors were padded and there was a wall of mirrors on one wall. Dean jumped a little but took a deep breath and whatever he had planned to say had died in his throat. I looked at the mirrors, "I need to use sigils to protect these, otherwise they will break and we could get harmed."

Dean shook his head, "Chuck left a note, saying he already did it on the back of the mirrors."

I bit my lip and nodded, "Alright well would you like to start?"

Dean ran his hands through his hair, his wings were close to his body but slightly puffed up telling me he was nervous. He nodded slightly, "Yeah sure I uh… what are we doing first Cas?"

"I think we should work on you calling your angel blade to you. It's the simplest thing for you to do." I say softly. Dean nods a little, his wings folded against his back, but they had relaxed, I knew this was something that would make Dean feel a little better. "So your angel blade is a part of you, an extension of your grace Dean. Most of the time angels call it from their wrist, but there are a few that can call it from elsewhere. It is a matter of sensing where yours is and calling it from there. Then you can choose where you keep it,"

Dean closed his eyes, I could feel the slight surge of power as Dean called his angel blade, suddenly the blade appeared in his right hand. When Dean opened his eyes again he looked down at the blade and smiled proudly. "Easy!"

I rolled my eyes, "Fine Put your blade away and we can move to something harder." Once Dean had put his blade away I nodded, "Good. Now, something that is harder is healing yourself,"I grabbed a knife from my coat and slit my palm, showing Dean, "To heal yourself is more though based than anything." I quickly healed the cut and then looked at Dean. "It's harder to heal a vessel. But you are tied to your body so you can't leave it. You won't have to learn how to heal outside your vessel. If you get cut with an angel blade though it is harder to heal because an angel blade actually damages grace."

Dean was nodding silently, then he took the knife I had cutting his palm, wincing a little but then he looked at it, after a couple of seconds the cut he healed the cut. I smiled a little, "Well done Dean."

He looked at me, "Thanks, Cas."

I smiled, "You are doing well, it can take many angels hours to figure these things out."

Dean blushed deeply and handed me back the knife, "Really?"

I smiled a bit and nodded, "Yeah, I am happy. Hopefully, the rest of the training can go smoothly."

Dean nodded, then we started training on harder things, after a few hours Dean had had enough. I smiled a little, "You've done really well Dean. I am surprised how quickly you caught on, not that you aren't smart Dean, but because you are human that has been turned into an angel. Many angels take hours and hours to catch on and be to the level of skill you have reached."

Dean smiled a little, then leaned forward and kissed me. I blushed and kissed him back, Dean softly wrapped his arms around my waist. His wings wrapping around the both of us, I moaned slightly as Dean kissed me harder. Dean picked up his pace and one of his hands traveled down and he grabbed my ass roughly, making me moan again. I closed my eyes leaning into him, soon enough he pulled away and smiled, cupping my cheek and he softly said, "Thank you Cas, I am exhausted so can we go lay down?"

I nodded, "Yes of course Dean. As I said we are done for the day."

Dean nodded and we made our way back to his bedroom, after a few seconds Dean stripped down to his boxers and laid down, his wings folding comfortably this time and he yawned. I smiled a little and laid down with him, staying in my shorts and my t-shirt. Dean moved closer to me, kissed my cheek softly, "Thank you for laying with me Cas. I understand if you aren't comfortable and want to go to heaven or something while I sleep."

I shook my head, softly stroking a hand through Dean's hair, "No Dean it is okay, I like to be here with you."

Dean blushed deeply and nodded, then closed his eyes and he started to fall asleep. I watched him as he slept and I couldn't help thinking about how unfair this was to Dean, after all, he had been through already it wasn't right.
