A/N: Hello my readers. Here's Chapter 18! My brain is functioning properly now, so I believe I will be able to write adequate chapters. Two more chapters of the main story (18&19) and then the epilogue (20). Exciting, yes?

All mistakes are mine 'cuz I'm human, so forgive me.

I forgot to thank the people who reviewed chapter 16 yesterday(because my brain wasn't working ATM), so thanks to those people: roxxroj, Maddy Love Castiel, The Mysterious Shadow, Mirabilem Electo, keacdragon, and Ooyuki-chan.

Also, thank you to the people who reviewed last chapter: Ooyuki-chan, SARA1988, sasukerules9, keacdragon, The Mysterious Shadow, and Maddy Love Castiel.

Wow, geez! Almost at 100 reviews (only 12 away)! Thank you guys! :D

Okay, okay. Enough rambling. Let's do this.

Disclaimer: I do not own Supernatural, nor any of its characters.

Allons-y!

Dean and Castiel sit on the couch, enjoying each other's company. Dean is holding a book called "Cujo" by Stephen King and is reading it along with Castiel. Occasionally Castiel will ask a question, and Dean will answer it patiently, smiling. They stay that way about an hour before Sam walks over to them, clearing his throat. Dean snaps his head up.

"What's up Sammy?" Dean asks.

"Well, I was working on a case, about this witch," Sam begins. "And I need to finish it."

"Is this the one about the witch who takes away people's memories?" Castiel asks.

Sam nods. "I uh… need Dean in assisting me."

"One witch too much for you Sam?" Dean asks, patting Castiel on his leg and then stands up. "Fine. As long as it doesn't take long. Cas, stay here."

"You sure that's wise?" Sam asks.

"Of course," Dean says. "I'm not bringing Cas to a witch who could mess with him."

Sam shrugs and then motions Dean to follow him out the door.

"Make sure you keep that phone on you," Dean says as he walks out the door. "Anything happens, you call me."

Castiel watches them leave and then stands up, deciding to go to the library. The house is eerily quiet without Dean and Sam, and the angel is not sure what to do. Back when Castiel spent time in Heaven, at least he had something he could do. Now he wasn't sure what he could do. Castiel peruses through the numerous books that are on the shelf, eyes skimming the titles. A sudden knock makes Castiel whip around, eyes narrowing. Surely Dean and Sam wouldn't be back that soon, Castiel knows that. Castiel closes his eyes, focusing on where the sound is coming from. After a moment, Castiel opens his eyes.

"Gazardiel?" Castiel questions, looking around. "Is that you?"

A moment of silence surrounds Castiel before a flutter of wings sound and Castiel finds himself staring at another angel.

"Castiel, I have urgent news," Gazardiel says. "Remember the vials of Lucifer and the Voice I took?"

Castiel nods. "What has become of them?"

"One of our angels has taken them," Gazardiel says. "I am afraid for your safety. It is likely they want to put them back in you, or worse, use them for something worse."

"What am I to do then?" Castiel questions.

"Go to Dean," Gazardiel commands. "I am going to find the angel who has taken them. Be careful Castiel." Within a second Gazardiel disappears.

Castiel stands for a moment, deciding what to do. He did want to go to Dean, but then again Dean told him to stay here. The angel did not want to burden Dean with another task. Castiel sighs and then decides to go to Dean. Castiel stretches his wings behind his back and takes flight to finding the brothers.

It takes only five seconds, but Castiel lands in the car as soon as he finds them. "Hello."

The Impala swerves sharply before continuing straight. "Jesus, Cas! Warning next time!" Dean says, staring in the rearview mirror. "Why are you here?"

"My apologizes," Castiel says. "Gazardiel told me to stay with you. Apparently an angel has taken the vials of Lucifer and the Voice."

"What would an angel want with them?" Sam asks.

"Whatever it is it can't be good," Dean says, sighing. "What is Gazardiel going to do?"

"He has told me he intends to find the angel before something happens," Castiel says. "I am not sure how that is going to go."

"Well, we're almost at the witch's house, so, I want you to stay low while Sam and I clear this up quick, alright?" Dean asks, glancing at Castiel.

Castiel nods as they pull up to a dark house. Dean and Sam get and then take out their equipment.

"Stay here, please," Dean says to Castiel, staring at the angel who nods in response.

Castiel waits as patiently as he can-which is hard because he doesn't know what Dean and Sam are doing. He watches as he sees the inside of the house light up and gun shots sound. About fifteen minutes later Dean and Sam walk out, a bit ruffled, but unharmed to Castiel's relief.

"Friggin' witch was a pain in the ass," Dean sighs as he and Sam hop in the car. "You okay Cas?"

Castiel nods in response and goes to look outside the window. Something did not feel right. Thunder suddenly booms from the clouds, followed by lightning, rain pouring down soon after.

"Gazardiel," Castiel says, glancing around and then flies out of the car.

"Cas!" Dean yells, looking out of the car to see the angel just standing.

Dean and Sam sigh and get out of the Impala. "What's going on?" Dean asks.

"Gazardiel's in trouble," Castiel says, frowning. "I do not know who he's fighting."

"Is it with the other angel?" Sam asks.

"It is possible," Castiel says, looking around. "He's around here, but he won't show himself."

Thunder continues to rule the air as the rain falls harder.

"This is not going to end well," Dean mutters.

"What makes you say that?" Sam asks.

"It's raining," Dean says. "Something terrible always happens when it rains."

"Now, what makes you say that?" A voice questions and Dean and Sam turn to see a tall man standing. Next to him was Gazardiel, who looked worse for wear.

"Castiel," the angel says. "Good to see you."

"I can't say the same for you," Castiel replies and turns to Gazardiel. "Are you okay?"

"I'm fine," Gazardiel says, glancing at the angel next to him.

"Let him go," Castiel says, glaring at the angel.

"Wish it was that simple, but I can't," the angel said. "See, either you come with me, or you let me put these…" The angel holds up two vials, "back in you."

"Like Hell we're handing Cas over," Dean shouts. "Why don't you back off?"

"I was hoping for a peaceful negation," the angel sighs, taking out an angel blade. "I suppose you don't want Gazardiel to live then."

"Just hold on, please," Castiel says, advancing forward. "Nobody needs to die."

Dean immediately steps in front of Castiel. "You stay behind me."

"I'll make this clear, and I'll say it only once more," the angel says. "Give me Castiel."

"Go screw yourself," Dean snarls. "You're not laying a feather on him."

The angel smirks and raises the angel blade. "Suit yourself."

A/N: Annnnnd, end chapter! Hope you liked this chapter! Next chapter is the last of the story, and then the epilogue! :D

BTW: There's a high probability Castiel will be returning in Season 8. :D :D

Until next time! *salutes*
