Quick Author's note: This is kinda dark, I do write darker but I wanted to test out what people think about this.
"Oh no...Dean? No...this isn't you" Castiel tried to tell the demon Dean. Dean had the angel sword and held it against Castiel's throat. Castiel couldn't bring it to himself to hurt Dean.
"Dean? Please! I know you're in there" Castiel begged the demon.
"He's here with us. Watching. He's going to feel your blood on his hands and won't be able to control anything. Oh Dean and his need to protect people. His guard was always up except around you. I wonder why. I see and hear his every thought and it surprises me. He doesn't trust his own brother but he trusts you?" The Demon in Dean was slowly killing Dean but also Castiel's mental state. The demon nicked Castiel's face in a couple places. This was to drive Dean mad. It was working because Dean was screaming inside and wasn't able to do anything about it.
"STOP IT!!! LEAVE MY ANGEL ALONE!!!! I'LL KILL YOU!!!" Dean screamed inside.
"Dean, it's okay. I know you're in there! Fight it! I believe in you" Castiel choked out. The demon started to kick and punch Castiel to break him. Castiel let the demon beat him because he simply couldn't bring harm to Dean. Castiel spit out some blood on the floor from the punches to the face.
"Dean, i'm sorry. I failed you again" Castiel felt like everything was his fault.
"Cas...yes you failed him and because of you, you'll both die" Dean, the real Dean called out for Cas but the demon took control again to abuse Castiel.
"I heard Dean! He's going to gain control and kill you" Castiel still had hope in the hunter.
"Maybe i'll let him have some control because he'll kill himself to save you and to get rid of me...ummm...or maybe i'll kill you then let Dean kill himself. You see, Dean is your weakness but you are Dean's weakness too" the demon teased Castiel before he marked up Castiel's face with more nicks.
"CAS!!" Dean was able to gasp out as his body cut Castiel.
"Shh save your energy to fight the demon" Castiel whimpered as he was being beaten again.
"I should have seen it before!" the demon took control again. "You two love each other! Oh I love messing with...RUN CAS!!" Dean tried to warn Castiel but it was too late the demon kicked Castiel's gut knocking him down.
"Dean, before I die I must tell you. It's true, I love you. Please, you must live for Sam. Fight to win..." Castiel passed out from a mixture of blood lost and the beatings he has suffered.
"ENOUGH!!!" Dean screamed as he gain control of his body. The demon left Dean knowing if it didn't Dean would kill him. Dean kneeled down beside Castiel and pulled him into his arms.
"Cas, please, oh god! Please wake up Cas!! I need you" Dean begged and started to choke up.
"Don't you die on me. Listen to me, I love you too" Dean held Castiel's body and started to sob. He was too late. Dean put his head on Castiel's chest to listen to his heart beat. He heard Castiel's heart beat get slower and slower and less frequent to the point where it stopped. Dean sobbed hard, gripping the man he love tightly.
Days turned into weeks and weeks turned into months. Dean was never the same. He still didn't look at women the same way but he would drink himself to sleep. He couldn't fall asleep without the bottle. When he did sleep it was for three hours at most. He would wake up soaked in his sweat and screaming for Castiel. Everytime he closed his eyes he would be starring into Castiel's deep blue eyes. Dean would drown in alcohol and Castiel's eyes. Dean wasn't able to dream anymore. Instead his mind would replay that awful day. It would play over and over on repeat. He could hear Castiel's voice clearly. What would make Dean sob in the middle of night was hearing Castiel say he loved him. Dean would pray every morning that Castiel would come back. Sam was extremely worried about his brother's condition. Sam would try to make him laugh, smile or even grin. He couldn't. Nothing could save Dean from the depression. Sam even took the weapons away from Dean for a while there. Dean would point the barrel of the gun at his head, heart or the roof of his mouth every night. Dean cut the word 'sorry' on his inner thign. He felt guilt and sorrow wherever he went. It seemed like Dean was empty and didn't want to live.
~few more months later~
"It's okay Sam, you don't need to hug me" Dean said waking up on his side and felt someone hugging from behind.
"I think you need it" a familiar deep voice whispered. Dean turned around to see Castiel.
"I'm seeing things again" Dean tried to explain it.
"No Dean, i'm here. It's me" Castiel gave Dean a smile. Dean bury his face into Castiel's chest as he squeezed Castiel tightly, releasing all the pain and suffering he has felt for three years.
"It's okay, I'm here. I'm not leaving you" Castiel started to tear up.
"Cas, I love you so much" Dean sobbed the looked up at Castiel.
"I love you too Dean. I'm sorry. I saw everything. I saw the attempts, drinks, drugs and your blood you spilled. I was trapped and forced to watch your spiral down to this. I tried so hard to get to you. I was caught at least once a day trying to leave to see you. They hurt me more because I love. Angels are suppose to love humans. Not in this way. They gave me a choice, I can become an angel or stay human..." Castiel did all the talking knowing Dean just wanted to hold him tightly to make sure he was truly back. Dean looked up to Castiel with red, puffy green eyes. Castiel's heart broke seeing that. Castiel thought it was bad enough watching him from far but this hurt so much more, holding the hunter and looking into the raw pain of Dean.
"Cas? What did you chose?" Dean choked out, starting to piece himself together.
"What do you think dummy? I wouldn't be allowed to see you if I was an angel again." Castiel tried to lighten Dean's spirits.
"But why? You've been trying to get your grace back for years." Dean asked, clearing up his eyes.
"I don't want my grace back if it means I can never see you again. I've been waiting to come home." Castiel smiled at Dean.
"Home? I thought heaven was home" Dean was confused.
"Home is the place you feel loved and welcome. You taught me that. I am at home with you" Castiel wanted Dean to feel good. Castiel softly cupped Dean's face in the palm of his hands. Dean couldn't help himself but to melt inside and look into Castiel's bright blue eyes. Castiel leaned forward and kissed Dean's smooth, soft lips. Dean kissed Castiel back right away, slowly bringing his hands to Castiel's neck and pulls them closer. Castiel leaned to Dean's ear and whispered to him. "Never again, i'm with you till the day you die"
"Good, I can't loose you again" Dean whispered back. Castiel touched Dean's thigh and healed the 'sorry' scar.
"You'll never loose me" Castiel kissed Dean softly.
