"And God said let there be light." - Genesis 1:3

"Sammy... Sammy? Are you alright?" Dean asks. They're sitting in the impala, which has been flipped around. He looks outside. Everywhere he sees destruction.

He looks at Sam. His eyes are closed. There is a lot of blood on his forehead. Dean grabs Sam by his head.

"Open your eyes... Sammy, open your eyes!" He says. He remembered telling his brother to close his eyes. He was going to kill his own brother. He was going to kill the only reason he had to live.

Suddenly Sam coughs. "Sammy!" Dean says.

"Ugh... What happened?" Sam asks, while looking outside.

"The Darkness happened." Dean opens the door of the car, and they both crawl out of the car.

"Look what it did to my baby..." Dean says, as he puts his hand on the destroyed impala.

"Where'd it go?" Sam asks.

"No idea, but I know that this thing is trouble, and I mean real trouble." Dean says. He grabs his phone. "I'm gonna call a cab."

They arrive at a motel. Sam grabs his laptop, and he checks the news.

"People from all around the world are complaining about the sky being filled with dark clouds." Sam says.

"Wait, so that means it hasn't gone all Apocalypse-ish yet?"

"Apparently not. But that's a good thing, right?"

"Let's hope so." Dean says.

Dean looks outside, at the sky. "Sammy..."

"Yeah?"

"What time is it?"

"5 pm, why?"

"You might want to take a look at this..."

Sam rushes to the window and he looks at the sky. It's covered in black clouds.

"My god..." Sam whispers.

"He's gone."

"Castiel, pull yourself together!" Crowley yells at Castiel. He dives away from Cas, who's trying to kill Crowley because of Rowena's spell.

Castiel tries to stab Crowley again, but he dives away again.

"After all I've done for you? I gave you those souls from Purgatory, remember?" Crowley says.

Castiel gets mad again. He runs towards Crowley, but Crowley runs through the room.

"Okay, bad example! But I gave you the First Blade, didn't I?"

Castiel doesn't seem convinced. Suddenly Crowley stays in one place.

"Why am I even still here?" He says. He snaps his fingers and he leaves.

Castiel looks through the room. He screams it out as he collapses onto the ground. His eyes start glowing. He falls forwards.

After a while he wakes up. He looks around. He stands up again and he whipes some dirt off his trench coat.

"What did just happen?"

Apparently angels were too strong to be killed by that spell.

His phone rings. He answers.

"Hello?"

"Cas! Are you seeing this, too?" Dean says.

"Seeing what?"

"Look outside, Cas."

Cas walks towards the windows. He sees a dark sky.

"It's dark outside, I can't see anything." Cas says.

Dean facepalms. "That's the whole point, Cas! It's 5 pm and it's dark outside!"

"Indeed. That means the sun went down quite early today. So, why did you call?"

"Oh, it's nothing. It's just that the fricking Darkness escaped when the Mark was removed!" Dean says.

"What's the Darkness?"

"It's something bad, Cas. Something real bad."

"How bad?"

"Death said that it took God and the Archangels to lock this thing into the Mark."

"Wait, Death? Why were you with Death?" Cas asks.

"Long story. Either way, I killed Death."

"I'm gone for a moment and in the meantime you release the Darkness and kill Death?"

"No, you guys released the Darkness when you removed the Mark from my arm."

"So what should we do now?"

"I don't know, can't you arrange a meeting with God or something? We could really use his help right now."

"It's not like I have God on speed dial, Dean. He hasn't been heard from for too long. He's long gone."

"Okay. Cas, you should prepare the angels for war. This thing will start killing, it's only a matter of time. We will try to learn as much about the Darkness as we can." Dean says.

"I can't go to heaven right now."

"...Why not?"

"I might've accidentally freed Metatron."

"Okay, why don't you just come to us, so you can be useful."

They end the phone call.

"You got something?" Dean asks to Sam.

"Yeah, this says that a tornado of dark clouds destroyed a weather station an hour ago." Sam says.

"We should probably check it out." Dean says, as he grabs the car keys. Then he realizes that the Impala is a wreck.

Sam looks at Dean with a dead stare.

"I need my baby, Sam."

They arrive at the weather station. They were brought by a cab.

"Hi, I'm officer Smith and this is my partner, officer Bieber, FBI." Dean says.

Sam quickly looks at Dean with an angry face, but then he looks at the police officer standing in front of him.

"Not related to the other Bieber..." Sam says. Dean smiles.

"Why is the FBI interested in a tornado?" The police officer asks.

They are both quiet for a moment.

"Weather machines. That create... tornadoes... and stuff!" Dean says.

The police officer nods slowly.

"Do we have a list of the victims?" Sam asks.

The police officer nods, as he shows them a list.

"The tornado was very unexpected. They were quite unlucky." The police officer says.

"Indeed." Dean says, as he looks at the list with pictures.

"Can we keep this?" Sam asks. The officer nods.

They look behind them. They see Cas walking towards them.

"Hello." Cas says with a big smile on his face.

"Cas, do any of these names ring a bell to you?" Sam asks.

Cas looks at the list of people who died.

"This name rings a bell. Derek Wright. His name seems to be put inside of my head, just like with the prophets."

"I thought you said that Metatron turned that off, so that there wouldn't be any prophets." Sam says.

"He isn't on that list. But... Chuck is on the same list as Derek."

"Wait, so that means that there are two generations of prophets?" Dean asks.

"I don't think so... Chuck is on both lists."

"How many people are on the list?" Sam asks.

"6."

Castiel gives their names. Sam grabs his phone, and he does some research. 4 of the 6 people on the list are dead. The ones alive are Alaina Hicks and Chuck Shurley. Chuck, however, was presumed missing, while Alaina lived quite nearby the place of the disaster.

"Do you guys know anything about why it's still dark?" The police officer asks when he returns.

"Aliens." Dean says, as they walk towards the car Cas drove towards this place. They drive towards Alaina's home.

"Someone home?" Dean asks, while he knocks on the door. A blonde girl opens the door.

"Who are you?" Alaina asks, as she opens the door.

"I'm Dean, this is my brother Sam and my friend Cas."

"Okay?"

"This is gonna sound weird, but we need you to come with us." Sam says.

"And why exactly would I do that?"

They realize that there is a stronger wind. They look at the sky, and they see clouds turning around, preparing to make a tornado.

"We have to hurry." Cas says, as he grabs Alaina by her hand.

"Hey, let me go!" Alaina says. They drag her into the car.

"Let me go! Help! Someone help me!" She yells. Then she watches as her house is struck by the black clouds.

"Drive, Cas! Drive!" Dean says.

"What the hell?!" Alaina says. Black clouds follow the car.

"We will try to explain! By the way, do you happen to know Derek Wright or Chuck Shurley?" Sam asks.

Alaina shakes her head.

"My home... it's gone!" She says. She is crying. She couldn't believe what was going on.

"What was that stuff?" Alaina asks.

"It's the Darkness. You were it's target. We don't know why, but we're trying to figure that out." Dean says.

They look behind. The black clouds that were following them were gone.

They drive towards te Men of Letters bunker. They bring Alaina inside.

"This will be your home for a while. Trust me, it isn't as bad as you'd think." Dean says to Alaina.

"If I didn't see that stuff for myself I would call you guys crazy. But are you sure that I'm safe from whatever it was in here?" Alaina asks.

Dean thinks about how Kevin died in the bunker.

"No, you aren't, but it's the safest place there is."

"Do you have any idea why it's after you?" Sam asks.

Alaina shakes her head. "I work as a librarian. It's not like librarians usually make clouds angry."

"If you're a librarian then this must be heaven." Sam says, smiling.

"This is not heaven. This is a library. There is a difference." Cas says.

They hear someone knocking on the door really hard. Dean walks towards the door, and he looks through a gap to see who it is.

He looks at Sammy again with a surprised face. He opens the door.

"Chuck?"

"We need to talk."
