"Cas, buddy, we need your help. Can you come down here?" Dean prayed, his eyes closed. He had sent Sam to the daughter of the man who killed his wife and committed suicide after that for questioning. This has been the most recent killing. They both couldn't find out what kind of creature possessed him.
Earlier they went to the morgue and both searched the man and woman, but couldn't figure out what exactly happened. It may have been a demon, though Dean thought it could have been a siren.
He slowly opened one eye, hoping to see the blue eyed angel standing in the room. Lucky for him, Castiel wasn't busy with heaven stuff right now so he flew to the motel room the Winchesters were currently staying at.
"What's wrong Dean." Castiel asked, once Dean opened both of his eyes. Dean stood up from the bed and walked towards Castiel with a serious expression on his face. "There has been a few killings and we can't seem to figure out what did it." Dean explained. "So we need you to come with us to the morgue, maybe you see something we missed."
"Okay, I'll see you at the morgue." Castiel said, spreading his wings and taking off, not wanting to bother Dean. He landed outside the morgue and decided he'll wait there for the hunter.
Meanwhile, Dean went to the bathroom and changed his usual flannel and jeans for a suit. He opened the door and walked out, only to be hit with something hard. He fell to the ground and his vision went darker, until he blacked out.
The same siren, who made the man kill his wife and himself, had been following Sam and Dean for quite a while. Its plan was to catch one of the siblings alone and make him kill the person he desired the most. The siren heard Dean saying Sam was on questioning duty so he followed Dean into the motel room.
The siren was standing outside, listening at the door, when he heard Dean prayers and a second voice soon after. The voices were having a conversation until one voice said. "Okay, I'll see you at the morgue." It went silent after that.
This was his time to strike, so he lock picked the door and waited until Dean came out of the bathroom. He grabbed a gun laying on the bed, but decided not to kill Dean just knock him out. And that was exactly what happened.
After Dean was lying on the floor unconscious, the siren walked out and headed to the morgue. The siren had looked into the hunter's head and saw a certain blue eyed angel with raven black hair. He saw the moments they had together, the good and the bad. He also saw the most important of all, the love Dean has for him. That amount of love made the siren interested.
The siren arrived at the morgue and saw Castiel in front of it. He stood still, inhumanly still, almost like a statue with a thoughtful look on his face.
The siren shape shifted into Dean, also wearing a suit, and greeted Castiel.
"Hey Cas, let's go inside." Siren Dean smiled and put a hand on Castiel's lower back, guiding him inside. Looking into the angel's head was a bit harder, the only thing he saw were bright colors. Castiel's eyes betrayed him, as the siren saw the love and adoration clearly in his eyes.
How Dean never noticed it, was beyond him. But this would make things even more interesting than it already was.
Siren Dean watched Castiel as he examines the woman first. He doesn't find anything weird so he walks over to the man. Castiel touches the arm of the "The man has high levels of oxytocin his blood, this hormone is associated with being in love. I think you're dealing with a siren." Castiel said, turning to siren Dean. "Thanks Cas. I'll tell Sam." Siren Dean smiled, walking out of the door. He cocks his head around and smirked. "Are you coming or what?"
Castiel hesitates only for a second and catches up with Dean, walking outside again.
"You know I love you right." Siren Dean suddenly said once they were outside and heading to Baby.
Castiel stops in his tracks, his eyes widened, as he stares at the back of siren Dean's head.
He doesn't know what to do, so he just stays silent until Dean has explained himself.
"Come on Cas, I thought you knew." Siren Dean turned around and smiled at him. "You told me you loved me like a brother." Castiel said, his eyes squinting in disbelief.
Dean can't love me, that's impossible.
"I didn't mean it." Siren Dean said as he inched closer and closer, stopping just a few inches away. "I was just afraid you didn't feel the same. But you do right."
"Erm- yes. Ahem. Yes, I do." Castiel stammered, looking up at siren Dean. His eyes flickering from his lips to siren Dean's beautiful grass green eyes and back to his plump, soft lips.
Siren Dean smirked and crushed Castiel's lips with his own. Castiel wasn't expecting that. He thought that if Dean would ever kiss him, it would be sweet and loving instead of harsh.
Castiel pulled away after a few moments of lip bruising and said a quick goodbye, before flying off. He needed time to think.
Dean, the real Dean, woke up lying on the ground of the dirty motel room. He searched for his phone and looked at the time. About a half hour had past. At first he was confused what happened, but then he remembered an ugly looking creature knocking him out with the handle of his gun. Dean realized the creature could only be a siren. The first thing he did was calling Sam, warning him a siren was on the loose.
Now he could pray to Cas.
"Cas, get your feathery ass down here. There is a siren walking around right now." Dean prayed, hoping Castiel would hear him.
Castiel did respond immediately and flew into the room. "Hello Dean." He said awkwardly, looking anywhere, avoiding Dean's gaze.
"Hey Cas, what happened." Dean asked, worry taking over. Castiel was not acting like he normally does. Dean wonders what happened in the half hour he was unconscious.
Castiel glared at him with fiery eyes, making Dean step backwards. "I thought you loved me. Gabriel explained that when you love somebody you asks them out. Why haven't you asked me out?" Castiel almost shouted, leaving Dean at a loss for words. What was he talking about?
"Cas, buddy, I don't understand." Dean said, raising his hands a small bit, trying to calm Castiel down.
"Do. Not. Call. Me. Buddy." Castiel said angrily, stepping forwards towards Dean with clenched fists.
Dean backed against the wall, confused about this whole conversation.
"Cas, listen, I'm sorry, but I have no idea what you're talking about. I have never said that I love you." Dean explained, waiting for a blow that never came.
Instead Castiel stopped, confusion written all over his face. His eyes defeated, almost sad.
"But you said it, at the morgue." Castiel said with hope in his eyes. That hope instantly disappeared when he realized. "It wasn't really you."
Castiel was now on the brink of tears. "It was the siren."
His tears were now falling, leaving wet trails on his cheeks. He sobs and raised his wings, ready to fly and never come back, when a voice stopped him.
"Don't go." Dean desperately said, walking over to Castiel. He gripped his arm, making sure he couldn't leave.
"The siren had one thing right." Dean softly said, a small smiling tugging at his lips.
"What." Castiel whispered, not sure what to say.
"I do love you." Dean said, his hands caressing Castiel's cheeks. Dean leaned in and softly captured Castiel's lips in a sweet kiss. The kiss only lasted a few seconds, but in Castiel's eyes. It was perfect, the kind of kiss he needed from Dean.
"So do you want to be my boyfriend, angel?" Dean asked, his forehead resting on Castiel's.
"Yes, I would love to be your boyfriend." Castiel said, kissing Dean again. They both smiled into the kiss, when Dean slowly pulled away.
"Now if you excuse me, I'm going to gank the son of a bitch who dared to kiss MY boyfriend." Dean said, grabbing the colt and walking out of the door leaving a smiling Castiel behind.
