As a human, Cas knew it was a good idea to learn about human culture. He decided to start with music, as Dean seemed very passionate about it.

While the boys were on a ghost hunt, Cas decided to get on Sam's laptop and "Google" popular music. He didn't exactly know where to start, so he just typed "heaven music".

One of the suggestions said "heaven music video beyonce", so he just clicked on that. It took him to "YouTube" and he was shown a "music video" of this "Beyoncé" woman. He was astounded by the way she sang, the way she moved. It was amazing.

He thought there was some sort of meaning behind the video. There was a woman being possessed by a strange demon of sorts. She was successfully exorcised, but the "meatsuit", as Dean usually called them, didn't survive. The video mainly took place at her funeral. And at the very end, there was a version of the exorcism. And heaven couldn't wait for her. Obviously.

He wanted to watch more of these videos, so he clicked on the first result after the "advertisement". It wasn't Beyoncé. It was by a strange woman known as "Katy Perry". Unconditionally or something. Then he discovered "Rihanna" with What Now. Then he found his favorite YouTube woman.

Shakira.

He watched Can't Remember To Forget You, and he was enchanted by her voice. It was beautiful. He also saw the Rihanna woman. The video was described as "steamy", and Cas had to agree. That water looked quite warm.

He wanted to hear more of her music, so he returned to "Google" and looked up "shakira". He found many songs. La La La, She Wolf, Loca. Cas's favorite was Hips Don't Lie. It was "catchy".

When Sam and Dean returned from the hunt, Cas was quietly humming the tune to the song sitting in the library. He'd memorized the lyrics and knew them like he knew the names of all the prophets.

Dean heard him humming and was immensely curious.

"Cas, what're you humming?" Cas looked up at him excitedly.

"A song by the most amazing YouTube woman." He grinned from ear to ear. Dean chuckled.

"Alright, who is this YouTube woman?" Cas stood up, standing right in front of Dean, smiling away.

"Oh baby when you talk like that

You make a woman go mad

So be wise and keep on

Reading the signs of my body

And I'm on tonight

You know my hips don't lie

And I'm starting to feel it's right

All the attraction, the tension

Don't you see baby, this is perfection."

Dean couldn't help but burst into laughter. Cas's smile faded away. Was this bad?

He couldn't help but feel a little hurt by his reaction. He felt tears in his eyes. He rushed out of the room before Dean could see them.

He locked himself in the bathroom and sat on the floor against the wall, burying his head in his knees. He let the tears flow.

How could Dean laugh at him like that? It really hurt. He could hear Dean knocking on the door asking him to come out, but he ignored him. He was too upset with him.

"Come on, Cas, I'm sorry!" Dean called.

"Go away!" Cas sobbed.

"I'm sorry, I couldn't help it!"

"I don't care! Just go away!" It was another few minutes before Dean came back. He knocked on the door rhythmically.

"Do you wanna come forgive me?

Come on, I didn't mean it.

I never see you anymore,

Come out the door,

Didn't want you to feel mistreated.

We're supposed to be best buddies,

And now we're not.

I just wanna see you again.

Do you wanna come forgive me?

I'm just trying to apologize."

"Go away, Dean." Cas muttered just loud enough for Dean to hear.

"Okay, bye."

A few minutes later, the same knock.

"Do you wanna kill a demon?

Or ride the Impala 'round all day?

Just wanna make you feel better,

Won't have it any other way.

It gets a little lonely,

Without you by my side,

Just watching the hours tick by!"

Cas was hardly paying attention. He was too upset to care. A few minutes later,

Knock, knock, knock.

"Cas?

Please, I know you're in there.

Sammy's asking where you've been.

He says have courage,

And I'm trying to.

I'm right out here for you,

Just let me in.

We really need each other.

You and me.

'Cause I'm so in love with you.

Do you wanna come forgive me?"

It just made Cas sob even more. Dean loved him? It wasn't just him? But if he loved him, why would he laugh at him like that? It hurt his feelings, something he wasn't used to.

"Oh no, did I get too close?" He started singing quietly.

"Cas?" Dean murmured.

"Oh, did I almost see what's really on the inside?

All your insecurities

All the dirty laundry

Never made me blink one time

Unconditional, unconditionally

I will love you unconditionally

There is no fear now

Let go and just be free

I will love you unconditionally

Come just as you are to me

Don't need apologies

Know that you are worthy

I'll take your bad days with your good

Walk through the storm I would

I do it all because I love you, I love you

Unconditional, unconditionally

I will love you unconditionally

There is no fear now

Let go and just be free

I will love you unconditionally."

He sang the song until the end. Because he knew that was the best way to forgive him. He opened the door and took Dean into a warm embrace.

"I'm sorry. I just got upset." Cas cried.

"Sh, it's okay. You had every right. I was a bit of a dick."

"Why did you laugh?" Dean paused for a moment.

"Because I didn't know what else to do. You've got such an amazing voice, and I got butterflies in my stomach. And, to be fair, it was Shakira."

"Is that bad?"

Dean half smiled. "With you, it's so friggin perfect."

Cas took Dean's face in his hands and pressed their lips together. Dean kissed him back, placing his hand on the back of Cas's neck. They pulled back and touched their foreheads together.

"I'm sorry about everything, Cas." Cas shushed him and put a silencing finger on his lips.

"Don't be. Come just as you are to me. Don't need apologies."

"Oh, baby, when you talk like that, you make a boy go mad."

"Heaven won't wait for you. But I would."

(A/N: This sorta spiraled out of control. It was supposed to be a cutesy-tutesy little Shakira addiction. XD Sorry guys! And I actually watched the Beyoncé and Shakira music videos. They're pretty good .__. Shut up. :3)
