Dean shot up straight in bed. He was covered in sweat and breathing heavily. The images of his previous nightmare flooding through him, making him either want to punch something or curl up in a dark corner and cry.

He has had nightmares ever since the Mark disappeared. The nightmares were always the bad things he had done to the people he loves. A big part of those nightmares containing him beating up Castiel and the defeated look Castiel had. The angel didn't even fight back, he could have easily smite him but he didn't. The worst part was the look in Castiel's eyes when he almost killed him. The pure sadness in those big blue orbs.

Dean looked over at the alarm clock on his nightstand. It was only 2.36. He knew he wouldn't fall asleep anyways, so he threw the duvet off of him and stepped out of bed. He walked downstairs to the kitchen grabbing a beer and sitting down at the small brown diner table. The bunker was very quiet, due to Sam being asleep. He didn't mind the silence for a change.

If he can't sleep, why not drown his sorrow in alcohol? His beer was only half empty when he heard a familiar fluttering of wings.

"Cas?" Dean asks surprised, he thought Castiel hated him after what he did. Dean had prayed a dozen of times, but Castiel never seemed to answer.

"Hello Dean." Castiel's deep voice sounded from behind him.

"What are you doing here?" Dean asked, turning around looking straight into his deep blue eyes. He could get lost in those captivating eyes.

"I came here to see how you are doing." Castiel answered with worried eyes, his hand running through his already messy hair.

"I'm fine Cas, how are you? I haven't seen you in a long time."

"I apologize, heaven is chaotic after the darkness was freed. I wanted to visit you, but I never had the time. The angels need me." Castiel gave Dean a small apologetic smile.

"Yeah, it seems like the angels always need you." Dean said sarcastically, rolling his eyes.

Truth is, he needed Cas. Maybe even more than the angels do.

There was an awkward silence, neither knowing what to say. It used to be a lot easier to talk, mostly about nothing in particular. It just didn't feel right anymore and Dean couldn't find the words to actually ask Castiel for forgiveness, to afraid Castiel wouldn't accept.

"Look Dean-."

"Cas I-."

They looked at each other for a split second and Dean started laughing. The first time he has laughed in a long time. Even Castiel wore an amused smile on his face. When Dean finally got himself together, he looked at Castiel expectantly, waiting for him to start.

"Dean,-." Castiel started with a sigh. "I know things have been hard for you. I know about the nightmares you're having and I want you to know that I'm not angry. I just want you to forgive yourself."

"Forgive myself?!" Dean said, getting angry. His hands clutching the table, knuckles turning white. "How can I forgive myself when I hurt the people I love? How can I possibly forgive myself when I hurt you, of all people. I beat you up Cas, hell I nearly killed you. You have every right to be angry, to never want to see me again."

"Dean, please calm down. You weren't yourself. It was the Mark and you know it deep down. It's time to let that all behind you. Come with me." Castiel now walked in the direction of the staircase leading to Dean's bedroom.

Dean hesitated, but after a few seconds of not knowing what to do, he quickly stumbles after Castiel. When they arrived at Dean's bedroom, Castiel told him to lie down.

Dean gets into his bed and feels the soft duvet being thrown over his body. Snuggling into the warmth, he almost forgot Castiel was still standing next to his bed.

"Sleep. With all of the research you're doing about the Darkness, you are going to need it. Figuring out how the Darkness works is important, but I have learned sleeping is also important." Castiel said softly, trying to not break the peaceful atmosphere that suddenly arose.

Castiel was about to fly out of the room when he heard a faint whisper, coming from the hunter with the beautiful grass green eyes.

"Stay."

Dean didn't mean to say it, the word just slipped from his mouth. He was anxiously waiting for Castiel's response. When Castiel looked at him with gentle and caring eyes, he felt at ease.

"Okay." Castiel whispers back not quite knowing what to do. Should he sit down? Or maybe keep standing.

He felt a hand on his arm, pulling him towards the bed. Dean was now laying on the other side of the bed, making room for Castiel to lie down with him.

Castiel sat down and stripped to his white t-shirt and boxers. He felt Dean staring at him, but he tried to ignore it.
He lay down on his back and rested his head on the pillow. He didn't know what Dean wanted him to do so he decided to lie down very still and wait for Dean's instructions.

Dean let out a soft chuckle noticing how stiff Castiel looks. He scooted closer to Castiel and lays his head on Castiel's chest.

Castiel wraps his arms around Dean's waist, while Dean puts his hand next to his head on Castiel's chest.

Dean slowly falls asleep, enveloped in the warmth of Castiel.

It finally feels right again.
