"What's been up with you?" Sam raised his brow at his irked brother.

Dean sighed. It had been five days since he last spoke to Cas. It was bad enough that the angel peaked inside his brain to see the strange sexual thoughts...which by the way vanished completely after Cas left...but then he had to just disappear with no word of what he was doing. While relieved that the sexual fantasies were no longer swimming through his mind, he felt a strange hole inside him ever since Cas disappeared. "I'm fine, man. Can we just focus on the job?"

Sam scoffed. "Okay, now I know something's up. We finished the job yesterday. Seriously, dude, what the hell is wrong with you? It's like you're not even here anymore."

"Look, I'm sorry Sam but I can't talk about it," Dean groaned, shaking his head.

"Are you in some sort of trouble? Does is have something to do with Cas? Cause he's kind of been ignoring us for the last few days..."

"It has nothing to do with Cas!" Dean could feel the humiliation boiling inside him. "Just...just leave it, Sammy. Please."

Sam could tell how torn up his brother was, so he dropped the subject...for the time being.

Dean glanced up from the tv as soon as he heard the soft flutter if wings. "Cas?"

"Hello, Dean." he smiled warmly.

"Woah, Cas you've got-"

"Yes, Sam, I have physical wings now. This is old news," he retorted.

Sam glanced to Dean, who was still staring at the angel. He turned his attention back to Castiel and scoffed, "Well, it's new to me."

"Sam, do you mind giving Dean and I a moment in privacy?" the angel asked.

"Um...why?" he raised a brow at his brother, who just shrugged.

"It does not concern you," Cas growled, placing two fingers on the tall hunter's forehead. Dean's eyes bulged when he watched his brother collapse on the bed.

"Cas what the hell?!" Dean shouted.

"I apologize, he was asking too many questions. He's just asleep."

Dean rolled his eyes. "Cas, you can't just knock people unconscious when you need to talk in private."

"It is of great import, Dean. I wouldn't do it if it wasn't necessary...obviously," Cas retorted, noticeably irritated.

"All right...what is it?"

"I...shit..." Cas muttered, shifting his shoulders around uncomfortably.

"Did you just...curse?" Dean asked, eyes bulging out of his head.

"Apologies. My wings are incredibly uncomfortable," he sighed. Dean watched in awe as the wings stretched out, ruffling their feathers out. Damn, he just looks so adorable when he does that, Dean thought.

"Why is that?"

Cas stared for a moment before answering. "I...I do not know..." he lied through his teeth.

Dean could see the angel lying but decided to ignore it for the moment. "So what is so important that you had to knock my brother unconscious to tell me?"

"I found the reason you are attracted to my wings."

Dean blinked a few times. "Oh...and what is the reason?" he asked, relieved that it wasn't just some gay epiphany.

"Every few millennium angels find mates. Typically they are other angels but every so often you find an angel who finds a human mate. The person an angel is meant to be with is automatically chosen at the angel's creation, no matter how long the angel must wait for that human other angel to be born. There is no choice in the matter, but when the time comes, the angel will grow physical wings if they are in a human vessel."

Dean raised an eyebrow, unable to believe any of what his friend just said. "How do you know all of this?"

"I talked to some other angels who have mates," he stated plainly.

"Right...well, I'm a guy, and you're a guy, and that's just weird, man. I'm into chicks!"

"I am indifferent to sexual orientation and/or gender. This is a male vessel. Would you prefer me in a female vessel?"

Dean couldn't believe what he was hearing. Cas wanted to mate with him? Why was this happening? And why exactly now? "No! No, no, no. That's all right. I'm used to this vessel, don't go changing on me now," he paused, thinking of how to put it. "Cas, you're my friend. You're the best friend I've ever had. Besides Sam and Bobby, you're the only person in my life I can count on. I just can't...think of you...in that way..."

Cas did his famous head-tilt. "You do think of me that way, Dean. And I don't have to read your mind to see it. It's written all over your face. You are attracted to me, and it scares you, because you don't know what to do with feelings toward my male vessel."

"Look, Cas! I CAN'T be your 'mate', or whatever...I just can't."

"You don't really have a choice. It's written into your brain. The more you fight it, the worse the feelings become."

Dean stood there, not knowing what else to say. "You need to leave..."

Cas stepped closer, backing Dean against the wall. "You don't want me to leave, I know you don't."

"I...I think it's best if you do..." Dean muttered, leaning his head against the wall.

Cas sighed, pulling away. "Fine," he said, disappearing instantaneously.

Earlier that week...

"Hey look! If it isn't my favorite little brother in a trenchcoat? What can I do for ya?" Gabriel grinned at Castiel's appearance.

"I need to speak with you. It's about my wings. They have taken a physical appearance and it is affecting Dean in a...strange...way."

Gabriel narrowed his eyes and pursed his lips before responding. "Hmmm...sounds like he's your mate. Congrats, Cassy!"

Cas was not amused. "Gabriel, this is serious."

"So am I! He's your mate. Every angel has one, be it another angel or a human. It's wired into their brain, and yours too. No matter how much they fight it, it's written in stone. It's meant to be."

Cas cocked his head to the side. "I do not understand..."

Gabriel rolled his eyes. "Lemme break it down for ya. Once your wings get physical, you've got 30 days. 30 days to do the deed with chosen mate. Otherwise, you lose your grace forever."

"Dean Winchester is attracted to women...does this mean I must acquire a female vessel?"

"Nah, he'll come around. He won't be able to deny his attraction to you for much longer. Eventually the dreams and thoughts and urges will become too much and he'll give in."

"You obviously do not know Dean," Cas stated.

Gabriel chuckled. "He is a stubborn one. It might take some seduction on your part, but don't worry, you can always just tell him he has to fuck you so you don't lose your grace."

"I will not get it that way. He needs to want it. I will not use him to keep my grace."

"So you've accepted your feelings for him? Huh, that didn't take too long."

Cas smiled softly, thinking of all the good times he and Dean shared. "I accepted my attachment to Dean Winchester a long time ago."

Gabriel smirked, patting his brother on the back. "Well, best of luck to ya. Need any tips?"

"I will return to you for advice if my current plan does not go accordingly."
