I wrote this story today. There is a gathering of fans that were upset with the Season 9 finale. I myself was surprised and kind of angry to have Dean end up as a demon. I had an inspiring moment to write this below so happy reading.

Dean turned feral after he killed Metatron. He was in full fighting stance panting and scanning the room with his black demon eyes. Sam approached his brother with caution. He carefully placed his hand on Dean's arm that's not holding the knife. "It's over Dean you killed him. We need to do the demon cure to get you back to normal."

Crowley stood there waiting. "Come Dean we have things to do. Leave these two here." He noticed the looks of determination from Sam and Castiel.

Dean gritted his teeth. "I am normal. This is who I am and you are not going to change me so get out of my way Sam." He shrugged younger brother's hand off his arm.

Sam attempted to stealth-fully place the demon bounding cuffs on his brother left wrist.

Dean realized what Sam was trying to do and instinctively swung the first blade. He sliced Sam on the arm with a growl. The younger Winchester stepped back quickly feeling stunned that his brother cut him. He placed his hand on the bleeding wound. Dean walked toward him with a dark look in his eyes.

Sam walked backwards. "Dean it's me. It's Sam. Stop this. It's getting out of control."

As soon as Dean was directly in front of him, he swung the deadly jaw bone upward to fatally strike Sam. Castiel instantly appeared in front of Dean. The blade sunk into Cas's abdomen and light was appearing from the open wound. Dean's black eyes widen in shock and dismay that he stabbed Castiel. "Cas?" he mumbled. "Cas!" He was about to pull the blade out of him. The angel held one hand keeping the blade still and used his other hand to place it on the mark of Cane. Dean felt a searing pain in his forearm. Looking down, the mark was fading away. There was a glow under the opposite arm appearing on Castiel's Coat sleeve. "I will release you from this cursed burden. It will die with me." Castiel gruffly said as his legs started to buckle from weakness.

Dean looked grief stricken. "Cas." his voice sounded hollow. Dean's eyes gradually changed from coal blackness to bloodshot green. Sam held up Cas by the shoulders as he slowly lowered him down. Dean scooted in front of him and held the angel close. "I am so sorry Cas." He knew he had a few seconds left with him.

Cas smiled with his eye half opened. "Live a good life my friend." He glanced at Sam "Both of you." The lights glowed in Cas's eye burning out his sockets as he fell limp.

Crowley stood there surprised by the whole scene. He realized it was his cue to leave. Quietly, he disappeared.

Dean yelled. "No!" He gently set his friend down to the ground. Tears were burning his eyes. Remembering what Cas said long ago, Dean ran over to Metatron's body looking around in his pockets to look for the vial. He could not find anything pulling on the dead angel's shirt collar. The man saw a gold necklace with a small glass vial containing glowing blue liquid. Yanking the necklace off the angel's neck, Dean ran over to Cas. "I can save you buddy hold on." Sam walked over to stop him from opening the vial. "Dean, Cas is gone. It's too late."

Dean shrugged his brother's hand off his shoulders. "No it's not too late I have Cas's grace. We can pour it in him and he will come back. I know he will."

They heard the sound of wings and Joshua appeared. "I am afraid it will not work Dean." He sadly said to the brothers. The dark skinned older man wearing a gardener's uniform walked over holding out his hand. "Give me Castiel's grace."

"I am going to smash this thing and he will come back." Dean was poised to throw the vial to the floor.

Joshua held out his hand. "Dean this body is too damage to accept Castiel's grace. Please hand it to me."

Dean looked at Joshua with sadness and rage. "Hell no! This is all I have of him."

Joshua spoke softly. "I can't let you keep Castiel's grace. It can be very dangerous if is handled wrong. God ordered me to retrieve it."

"Oh great! Dear old dad wants to take Cas's grace. If it was so important why didn't he prevent all this crap. At what cost huh? For entertainment? Playing everyone like we are an ant farm? Well he can go pound sand. I ain't giving it to him." Dean held on to the vial with a death grip.

Joshua sighed. "If you don't give it to me it will disappear from your hand anyway. He will not permit a human to hold on to an angel's grace. Please Dean. Hand it over."

Dean squeezed his eyes shut feeling the tears run down his cheeks. He handed over the grace to Joshua. Sam stepped to his brother putting an arm around his slumped shoulders. "I failed him again Sammy." Dean sobbed. "I killed him. How am I going to live with this?"

Sam held Dean tightly while his older brother's body shook with grief. He turned his head to Joshua. "Get us out of here please."

Joshua nodded his head. "I am so sorry guys." The brothers were back in the warehouse where they entered an hour before the last battle started. Sam steered Dean outside and placed him in the passenger side of the car. They got inside the vehicle. The younger brother turned to see Dean leaning his head at the window. Sam wiped a tear off his face turning on the car engine.

When they arrived at the bunker, Dean dragged himself into his room. He sat on the bed thinking about the whole event. His uncontrolled rage, the evil darkness inside him, the need to kill and everything that followed afterward. The somber man rubbed his hands over his face feeling total loss of his close friend that was there for him and Sam. He cared for Cas more than all the friends that made over the course of his life. Dean wondered how was going to be able to live day by day knowing he was the one responsible for killing Cas. All the hunting in the world will not rectify what he did. He thought of Sammy feeling relieved t his brother came out of this alive. He almost killed his own brother and his stomach turned thinking he went out of control with the first blade. If he killed Sam he would have killed himself afterwards. Dean would not have cared if he was sent to hell if he had his brother's blood on his hands. He felt the same way about Cas.

Dean heard a light knock and Sam opened the door. "Are you ok Dean? Do you need me to get you anything?"

Dean walked quickly to his brother and pulled him a tight embrace. "Sammy if I have killed you I would not be standing here now. I would have taken myself out."

"It's alright bro. I understand more than you know. Remember the demon blood? I felt the same animistic rage to kill. I felt powerful drinking the blood. I knew if I did not stop I would end destroying myself." He patted his older brother on the back. "Dean try to get some rest and I will come back later." Sam directed his brother to the bed.

Dean sat down. "Ok. I really feel like worthless crap right now. Cas... "Dean gulped not able to say another word.

Sam walked to the doorway. "I know but lie down and try to sleep."

Dean lay down staring at the ceiling. He was afraid if he went to sleep the whole day will replay in his head as a nightmare. It took a good while before his eyes finally shut in sleep.

Dean woke up to the sound of crickets and birds chirping. He raised his hand to his face feeling something brushing against his cheek. The feeling of the object was not familiar he quickly sat up and instantly noticed he was sitting in a field what looked like green field grass that was a foot high. The blue sky stretched out endless with large cumulus clouds lazily gliding by. He shielded his eyes with his right looking around wondering if this is a dream or wondering where the hell he was. Twenty feet away from him was a pond which looks like golden wavy flecks from the sun shining down. He spotted someone standing by the water.

It was a woman with long wavy dark gleaming hair blowing in the wind wearing a cream color sundress. The sun was also shining down on her; almost making her slightly fair skin glow. He can see a faint outline of her cheek as she was peering at the water. "Dean" she said in a familiar slightly gruff voice turning her head slightly toward the man lying in the tall grass. Dean squinted his eyes as he stood up walking over to the slender woman. The man felt his feet stepping on texture of grass and natural debris. She turned around to face the man walking toward her. Dean stopped in mid-stride with his face in stunned surprise. The woman eyes were cobalt blue like someone he knew very well. She had very similar features. The only difference is the face was very feminine in contrast to the his angel friend in his old tan trench-coat. "Cas?" Dean whispered.

She walked toward dean with a smile on her face. "Dean." her voice having the same undertone as the old Cas except it sounded husky and warm.

Dean closed his eyes hoping this was not a dream. When he opened them, woman stood before him grasping Dean's shoulders. Feeling delicate hands touching him acknowledged he was not dreaming. He instantly drew the new Cas into a tight hug. "Cas! I thought I killed you." Dean breathy said feeling joy and relief. "What happened?"

Cas chuckled. "You gave Joshua my grace. I recalled you giving him a hard time about it."

Dean looked surprised "How do you know?"

Cas smiled patting Dean on the arm. "I was in the vial so I was still aware what was going on. Joshua was instructed to find another body in Jimmy Novak's bloodline that can accept my grace. Jimmy had a cousin named Kathie that was terminally ill with cancer. Joshua asked her permission to release her to heaven and place me into her body. The poor woman was in so much pain and suffering from her illness she did not hesitate to comply."

Dean hugged Cas again. "I am so glad that you are alive." There was a breeze and soft tendrils of the Cas's hair brushed across Dean's face. He felt warmth in his chest that felt like his heart was coming to life. Like a dead seed blossoming to a flower inside himself. Feeling very aware he was holding a soft warm body a woman, the green eyed man gently pushed her back. He looked directly in those cobalt blue eyes. "Cas you really got a pretty vessel." Realizing what he said, he instantly backed way blushing.

Cas stood there blushing too. "Thank you Dean. I was surprised when I looked in the mirror after Joshua placed me in her."

Dean could not stop staring at her. It was hard to believe he will not see the awkward guy in the trench-coat anymore. Cas's presence still felt the same. Looking around curiously. "Where are we?"

Cas smiled "We are in West Germany in the countryside. Are you ready to go?"

Dean wanted to say not yet wanting keep this moment being with his friend all to himself.

Eventually Cas teleported them back to the bunker. They stood in the library watching Sam scrambling to put on his jacket and grabbing his keys. "Dean!" Sam looked over at his older brother. "Where the hell were you? I was worried you went somewhere and killed yourself." Sam was spewing off his anger. Then he was about to say more until he noticed a woman standing next to Dean. His eyes widen in surprised as he saw familiar features of the face before him. "Cas?"

"Yes Sam. It's me." She stood there smiling.

"Oh man I am so glad you are alive." He gave the woman a bear hug.

Dean held his hands up in protest. "Hey enough you are getting too cozy with Cas."

Sam laughed and let the angel go. "Dean has stakes on you now since you are in a woman." He watched his brother's face show annoyance.

"Very funny Sammy." Dean crossed his arms with a brooding frown.

"It's true bro. Remember what Cas said a while back. You two have a profound bond." Sam grinned.

Dean gave him a deadly glare. "Whatever." He grumbled. "No matter. She is back and hopefully here to stay." He walked over to Cas and put arm around her shoulders. "At least for a while right?"

"Don't worry Dean. I am not going to vanish. I will always be here for you." Her blue eyes directed at the other guy. "You too Sam. I will have to go to heaven from time to time since its being restructured. Joshua is leading since he is the only sensible one and has some kind of contact with God. He is tending heaven as an infinite garden keeping all angels in line with some assistance of course."

Later that evening, Dean was taking a shower. Sam and Castiel were sitting in the kitchen. Sam could not help staring at Cas's new appearance. "It's still amazing that you are here. This time as a female. A pretty female Cas. Dean will definitely be protective over you. I know you have angelic strength but he will see you as a woman not an angel. Be prepared for him to say he does not want you to assist on our hunts."

Cas smiled sat back in the chair. "I am prepared and will have to make it clear to Dean that he can't control an angel. I am relieved he did not kill himself over what he did. I would have been upset if he done something drastic. I will never forget the look on his face when held my dying vessel. Sam I felt so much love coming from him during those moments it broke my heart. He will never admit to me and himself but he does have a heart."

Sam glanced at the door and turned his face giving Castiel a serious look "Hey Dean was acting pretty possessive with you earlier. Did something happen when you took him out of here earlier today?"

Cas blushed a little "Well um he was very happy to see me and even hugged me twice. I felt his pulse rise a few times and the only responses I can relate to that he see me as an attractive woman. Sam I don't know if he attracted to the vessel or me."

Sam nodded in understanding. "Cas my question to you is pretty simple. Are you attracted to him? I know you guys had moments there was something kind of there but I know my brother he would never consider liking a guy. Now you are in a female vessel things are different now."

Castiel face turned a shade redder. She inhaled and in one breath she answered. "Yes Sam I am. I have been for years and being in a male vessel kept me from telling him. I knew his preferences so I could not show deep feelings to him. Other angels knew and picked on me from time to time but I ignored them and stood by Dean's side whenever I could. Would he accept me know since I am in this body?"

Sam took a sip of his beer. "It's a possibility he will but give him some time. Let him come to you Cas. Actually, I am glad it turned out this way. Dean needs someone that will accept him for who he really is. Will you be allowed to have a relationship with him if he makes his move?"

Cas nodded. "I have full permission to be with him in all aspects. I am still committed to serve heaven when needed but I was rewarded to stay on Earth if I chose to.

Sam smiled broadly. "That's wonderful Cas. Welcome back home buddy." He grabbed her hand and squeezed it.

Dean walked looking refreshed with his damp hair and wearing a t-shirt and jeans. "Hey what is going on here?" He scowled at his younger brother. The two people sitting at the table smiled at each other knowing it will be an interesting evening.

The brothers and the angel went out to the nearest diner to celebrate Castiel's return. Dean was chatty feeling lively and happy to see his friend again. He looked over at the woman across from him having a conversation with Sam. Dean got up to excuse himself to the bathroom.

"Dean is energetic! Castiel you did the best thing under the circumstances. The thought of having Dean as a demon was hard for me to accept. He practically became something we both normally hunt and kill. I thought for a second if he became monstrous I have to take my brother out." There were frown lines across Sam's face.

Castiel moved his glass of water to the left side of the table. "Well it did not come down to killing Dean. I would have been devastated like you. When Metatron told me he killed Dean you don't know how badly I wanted to destroy him right then and there. I was helpless do anything because that angel hid my grace and the other angels had no clue where it was." Cas lowered her head. "I did not have my grace to bring him back to life when Metatron killed him. I felt like I failed Dean."

Sam signed with relief as he saw Dean exiting the bathroom. "You didn't Cas. Everything turned out the way it was supposed to be. We got him back now and it's all that matters. Are you disappointed you lost your old body?"

Castiel gave Sam a slight smile. "Not really but I have to get used to this vessel. There are parts moving around that I am not use to dealing with if you know what I mean." The angel looked down at her chest.

Sam burst out laughing. "I did not think of that. Thanks for telling me."

Dean sat back down. "What's funny guys?" He looked at Sam laughing face and Castiel's dubious expression. "Well what is it?"

It took a few seconds for Sam to get under control. Gasping his words a little he replied. "Cas was expressing how he was getting used to his female vessel. Especially about certain parts that jiggle."

Dean understood the meaning and grinned. "Well Cas, welcome to womanhood. I don't envy you one bit." He chuckled seeing the confused look on her face.

Castiel was about to open her mouth in reply until waitress appeared with three small plates with apple pie. "Here ya go sweeties. Enjoy." The full figure older woman with the beehive looking hair walked away.

Sam looked at pie in front of him. "I did not order this."

Castiel nodded in agreement. "I did not order anything."

Dean smiled. "Come on fellas live a little. This is a celebration of Cas's return." She pushed her plate away. Dean gave the angel a serious glare. "Listen, you are going to eat every bit of that pie. Don't worry about your womanly figure. You're never going to gain a pound angel lady." Dean emphasized angel lady to drive his joke home.

The woman with the long dark hair and cobalt blue eyes picked up the fork. She took a bite of the pie and nodded. "The pie is good. Thanks Dean."

Dean sat here and huffed in achievement. "Great."

Sam set his fork down taking a sip of his water. "I found a new case for us regarding killings in Michigan. People are found with body parts missing. At first they thought it was a possible serial killer but there were animal teeth marks where people were torn to shreds. I thought it would be something we can check out."

"Good idea Sam. We can get our stuff ready to go tomorrow. Cas you out on this one." Dean pointed his fork at the woman.

Castiel pushed his small plate away. "Dean I am not a helpless female. I am coming with you."

The green eyed man gave her determined stare. "I am not saying you are helpless Cas. You just got this new body so you may need some time to get used to….you know." Dean paused. "The new you. The Cas version 2.0"

Cas frowned and shook her head. "I am not staying at the bunker. Do you want me to demonstrate my abilities?" The next moment the brothers were standing outside of Dean's car.

"What the hell!" Dean growled. "You teleported us? Hey, we did not pay for the meal."

Castiel smiled at the angry man. "I did and left her a good tip too. This was my point that I don't need to sit around. I can also say that you just returned to being human so perhaps you need time to get used to eating and sleeping again."

Dean opened his mouth to protest. He knew Cas was right. They both went through a rough ordeal and he couldn't show double standards on this situation. "Ok Cas, you got me there. We both need to be careful."

The younger brother snickered behind him. "Shut up Sam. As for you" he pointed at the angel. "You need to some new clothes. If you want to go hunting with us, you can't dress like you are going to a tea party."

"Fair enough, where do you want to go?" The woman smooth down her sundress. Dean had a blank expression on his face having no clue about women's attire.

Sam walked over nudging Dean. "Drive around man and find a sign that displays women's clothing. Drop me off first. I really don't want to be trapped with you shopping queens."

Dean gave Sam a death stare. "Get in the car meathead." They headed back to the bunker.

A few hours later, Dean walked with Cas back to his car. The angel's new attire was pretty form fitting. Dean did not mind her wearing the sundress but it was not practical if they needed help with hunts. He could not keep his green eyes of her dark blue t-shirt, indigo jeans and black boots. Dean even bought her a small silver ring similar to his including a bracelet to make her look chic. He drove back to the bunker and was having a hard time keeping his eyes on the road. From time to time, he glanced over at Castiel sitting in the car slightly nodding to the rock music playing through the speakers.

Dean parked the car inside the massive garage. He shut the garage door turning to see Castiel picking up a shopping bag of her old clothes from the back seat. They walked inside toward the Men of Letters library. "Home sweet home." remarked Dean as he placed his keys on one of the tables. Castiel placed the shopping bag in one of the chairs and turned around to glance at Dean.

The man watched her approach him with a slight smile. Her dark hair billowed around her face like a silk wavy curtain. "Thank you for the clothing and jewelry." She patted Dean's arm.

Dean gently grabbed her small right wrist. He felt how soft her skin was inhaling deeply. He was reacting to Cas's voice and the touch of her skin. "No problem." Dean gruffly said in a low tone.

Cas tilted her head not recognizing the tone in his voice. Looking up at him feeling concerned. "Are you alright Dean?"

Dean looked down at the pretty woman with the blue eyes. His breathing increased and his body temperature rose with emotion and longing. He could not help feeling this way and it's getting stronger around the angel. One lock of dark hair glided onto Cas's face. Dean moved his hand touching her cheek to smoothly tuck the hair back behind her right ear. He saw her eyes widen in surprised to be touched like this. That's when Dean realized he wanted to kiss Cas really badly by staring at her soft full lips. "Cas." he said hoarsely.

Cas looked deep in Dean's green eyes and saw him bent his head slowly toward her face. Dean's mouth was so close can feel his breath on her right cheek. Instinctively, she moved her hand to grab Dean's rough ones. She felt him entwined his fingers with hers. Then she felt his lips touch her right cheek moving over to her forehead. Cas stood completely still as she felt Dean's smooth mouth grazed her left cheek and hovered over her lips. Dean hesitated knowing the next action will change everything. He wanted a sign from Cas to know if this is what she wanted.

Cas stepped closer until her body pressed against Dean's. She murmured "Dean." softly. The woman moved her face upward touching her lips to his. Dean's body jolted from her action and instantly he moved his lips gently over hers. He tenderly kissed the pretty angel and then the kiss changed to a passionate one. Cas made a throaty sounds feeling Dean's tongue entering her mouth. She felt his strong arms encircle her waist. In response, Cas moved her arms up until her hands were in his hair. She put in every pit up emotion she ever had for Dean in their kiss.

They were enthralled in their passionate kissing; not noticing Sam entering the room. He stood there stunned by the view before him. Sam Winchester turned around grinning as he made a quiet exit. "It's about time." Thinking to himself as he walked back to his bedroom.
