Fallen

Chapter Five

"You're...an angel?" Dean whispers and Cas gives him a small nod. "...What do you want from me?"

Cas looks at Dean, confused. "I just want you to be safe, Dean Winchester."

Dean's heart pounds against his chest. "What do you need from my brother and I?"

"Excuse me?"

"Cut the bullsh-" Dean stops, going red as he realises he just swore in front of an angel of the Lord. "I know it's you who has been messing with our heads. Now's the time to tell the truth, Cas."

Cas stands up and stares at the wall. "It saddens me that you think I would ever do something like that to you, Dean." He walks into the living room and sits at the table, motioning for Dean to come sit with him. "I've been trying to keep them away from you. I'm the one who has been helping you quiet down the voices that you hear."

"And what are the voices, exactly? More angels? What do they want from us?" Dean walks over to Cas but he doesn't sit with him, he just stands with his arms crossed.

"Do you really think it was natural how your parents died?"

Dean's face hardens, taken aback by the abrupt comment. "They died in a fire. It happens, I guess?"

Cas gulps before speaking. "What I'm about to tell you is going to be very difficult to understand..." Dean's green eyes stare back at him. "Your father was the vessel of Michael, the archangel."

Dean's heart skips a beat. "V-vessel...?" He sits down in the seat next to Cas. "Why? How long was he in him for?"

"No, no, he was never in him. It is just written that John Winchester is the one that shall contain him. You see Dean, an angel needs permission to possess another human. Without the human's consent, they cannot enter. Your father refused."

Dean remembers Sam telling him how the voice he is hearing needs his permission. "And so they killed him and my mom?" He whispers, his voice cracking. "Why?"

It hurts Cas terribly, seeing Dean like this, but he knows he has to to be honest. "Michael didn't kill your parents, Dean." He looks down at his hands and then back up at the boy sitting next to him. "Lucifer did."

Dean's eyes widen and his breathing stops for a few seconds. "...Lucifer? Lucifer as in...The devil, Lucifer?"

"Lucifer was rising out of hell and Michael was the only one who could stop him. It is written that the two brothers shall fight to the death. Lucifer convi-"

"Wait, hold up. Lucifer's your brother?"

Cas raises an eyebrow. "Lucifer is an angel, Dean. He is an archangel who rebelled against God and for doing so, he was cast out of heaven. He is a fallen angel," Cas feels himself tense up. "Just like me."

Dean sees the sadness in Cas' eyes and he is unsure whether to ask him about it or not. What has Cas done that is so bad, they threw him off the bridge? 

Cas coughs, shifting in his seat uncomfortably. "Anyway, Lucifer convinced your father's brother to let him in. Michael, however, needed John, who refused to do so. Lucifer came to your house and purposefully burned his own vessel out, therefore starting the fire. The fire was to kill your father, Dean. It was so Michael wouldn't have a vessel. So Michael wouldn't be able to kill him."

Cas stops for a moment, letting Dean take in all of the information. "But what he didn't know, was that if John was killed, Michael would have a new vessel. The new vessel will automatically be the next on the family's bloodline. Do you understand what I'm saying, Dean?" He asks, quietly. "You are Michael's vessel."

Dean's jaw drops and his breath is acting like it is in a championship running contest. "I..But..Lucifer doesn't have...a vessel anymore, does he? He can't...do...anything...without...one."

"Lucifer soon learnt he also had a new vessel. And because John's brother didn't have any children, it went in a loop, back to your side of the bloodline. To Sam."

Dean felt those words coming, but he wasn't expecting to actually hear it. He stands up and clenches his fists, not able to make eye contact with Cas.

"So basically, you're telling me that if I don't say yes to Michael and let him in, Lucifer will kill me? But if I say yes then I'll have to kill Sam?" His eyes well up with tears. "I'm not going to say yes to him!" 

In one vicious swipe, Dean swings his arm across the table, flinging all the books and papers that are on it to the floor. He puts his hands on his head and lets the tears flow. Cas immediately stands up and pulls him into a tight hug.

"You're damn right you won't." Cas says. 

Dean pulls back and looks at him, confused. "Isn't that why you're here? To get me to say yes?"

Cas shakes his head. "Did you not hear what I said earlier? I want you to be safe. I'm here to watch over you and to make sure no one touches you," Cas leans in closer, staring at Dean's lips. "Well, apart from me, that is."

Dean lowers his head but keeps his gaze on Cas' eyes, a growling noise leaving his lips.

"I watched you when I was in Heaven and I fell for you, Dean. I fell for your humanity. And when they tried to get me to work with them on getting you to say yes, I wouldn't have it," Cas turns his back to Dean and rubs his temple. "They cast me out of Heaven because I wouldn't agree to putting you in any danger. I fell for you, Dean. Literally, and figuratively."

"Cas," Dean puts his hand on Cas' shoulder and gently turns him around to face him again. "I'm sorry."

Dean doesn't know what else to say. He met this boy yesterday, who isn't even a boy, but an angel which means he has probably been around for thousands of years. Cas has been watching him for a while now and Dean all of a sudden feels incredibly vulnerable and self-consious but all at the same time he has a gut feeling that he can trust him.

"I don't need your apology, Dean. You didn't do anything wrong. This was my choice. I wasn't going to tell you who I really was. You seemed happy. I would have loved for you to live a normal, human life. I was just going to make sure you were unharmed."

"You would have had to of told me someday. Sam's 24/7 hearing the fucking devil screaming inside his head, begging him to be his meat suit."

"We'll talk to Sam. I'll explain everything to him. As long as Sam doesn't agree to letting Lucifer in and I'm here, I'm not going to let anything happen to you. I swear."

Dean blushes. "Angels aren't supposed to swear."

Cas rolls his eyes and pulls him in close, their lips almost touching.

"Angels aren't supposed to be gay either," Dean smirks at him. "Such a rebel."

"Well, technically, I'm not. My true form doesn't have male or female parts..."

"Your true form? What are you, E.T?" Dean laughs.

Cas raises an eyebrow. "I don't...I don't understand that reference. I could find a female vessel, if that makes you more comfortable." He says, his face resembling much of a lost puppy.

Dean's smile widens. "Don't you fucking dare." And he closes the gap in-between them with a sweet, lingering kiss.
