A/N: As I was rewatching the first few episodes of the fifth season, this idea came to me and hijacked my brain. I had to write it, which put Not Alone on the back burner for the time being.
This story contains spoilers for the first five episodes of Season Five at the moment, so don't read if you don't want me to spoil the beginning of the season for you. I got direct dialogue from IMDB.com and youtube.com. If it sounds familiar, that's why.
Disclaimer: I don't own Supernatural or BtVS. I'm playing in their sandboxes.
Zachariah pointed at Dean. “You’re the Michael Sward.”
Dean looked at the angel confused. “Excuse me?”
“Well, more like a receptacle, Michael’s receptacle.”
“I’m a vessel?” Dean asked, incredulous.
“You’re THE vessel. A very powerful one, at that.” Zachariah confirmed.
“Why me?” Dean asked.
Zachariah laughed. “Because you’re chosen. It’s a great honor.”
“Oh yeah. Life as an angel condom. I think I’ll pass,” Dean scoffed.
Zachariah sighed. “I’ve had enough of your jokes.” He curled his fingers into the shape of a gun and pointed at Sam. “Bang.”
Sam fell the the ground, screaming. “You son of a bitch!” Dean shouted.
“You keep mouthing off and I’ll break more than his legs,” Zachariah threatened. “Lucifer is free and walking the earth. He’s going to murder them all, if we don’t stop him.”
“There’s a reason you’re telling me this. You need my consent. Michael needs my say so to walk around in my skin!” Dean spat.
“Unfortunately, yes,” Zachariah said.
“I’ll pass. The answer’s no.”
“Okay, how about this. We know your friend Bobby’s gravely injured. Say yes and we’ll heal him. Say no and he’ll never walk again.” Zachariah tried again.
“No,” Dean spat.
“How about we heal you from stage four stomach cancer?” Zachariah suggested.
Dean fell to the floor coughing. When he pulled his hand away from his mouth, there was blood in his palm. “No,” Dean groaned.
“Good choice,” a new voice broke in.
Dean, Sam and Zachariah looked around the dim room and their eyes fell on a woman. She was mostly in shadow, but her eyes burned a deep gold. “I wouldn’t have agreed to it either, the way that they were acting.”
Dean glanced at Sam, who shrugged, raising his eye brows before looking back at the woman. “Thank you, I think,” Dean said slowly.
“You’re not supposed to be here, and you know it,” Zachariah said angrily.
“I never did what I was told. I’m not going to start now. You can’t order me around, Zach, and you know it.” the woman said, stepping out of the shadows. With a wave of her hand, Dean’s cancer was gone and Sam’s legs were back to normal. Her blonde hair made her look like the angels in the pictures, Dean thought.
“You won’t stop me from getting Michael’s vessel’s consent. We’re in the middle of a war and we don’t have our general. That’s bad!” Zachariah shouted.
“Whose fault is that? I know I didn’t arrive until the middle of the movie, but I did warn you from the second I arrived that playing these two against each other was a very bad idea, and I have experience in things like this. You chose not to listen to me. You gave me Chuck to look after instead of listening to my concerns. You made your bed, now you sleep in it.” the woman ranted.
“You are rebelling against Heaven?” Zachariah accused.
“No. I am rebelling against you. And there is nothing you can do about it.” the woman smiled.
The two angels behind Zachariah were suddenly occupied. The first was attacked from behind, a knife thrust into his spine from behind him. The second attacked his partner’s attacker, only to find himself outmatched. He soon joined his partner on the floor. Their attacker looked up into the astonished eyes of Zachariah.
“How are you. . .” Zachariah started.
“Still alive? Good question. How did these boys end up on that airplane? Another good question. I think you know the answer,” the newcomer said.
“Cas?” Dean asked.
Castiel looked at Dean and gave him a slight nod.
“No. That’s not possible,” Zachariah spluttered.
“Possible or not, it’s happened. You will leave now,” the woman answered.
Zachariah left with a flutter of wings. “I’m glad to see you, Cas,” the woman greeted, walking up to him and giving him a hug.
“It was you, wasn’t it?” Cas asked.
“I was the one who did it, yes. But I’m also the one who brought you back. I like you.”
“Cas? You going to introduce us to her?” Dean asked.
Cas looked at the woman in his arms as if he just noticed she was there. “Sam. Dean. This is Ariel. She is the Archangel assigned to Chuck Shirley.”
“You’re hugging the angel who killed you?” Sam asked, confused.
“She didn’t kill me. She destroyed my vessel, then gave him back. She faked my death,” Castiel explained.
Ariel released Castiel and placed her hands on Sam and Dean’s chests. She closed her eyes and gave them a slight push. “You two need to be more careful.” Ariel watched as the two cried out and stepped back.
“What did you do to us?” Dean demanded.
“I carved Enochian Sigils into each of you. They will hide you from every angel and demon in creation, except me,” Ariel informed them.
“Why not you?” Sam asked.
“Because I’m the one who placed them on you, and I created them like that,” Ariel answered.
“What did you do, brand us with it?” Dean asked.
“No. She carved it into your ribs,” Castiel answered, as if it was the most obvious thing in the world.
“Of course she did,” Dean muttered, annoyed. “Not that I don’t appreciate what you did for me back there, why don’t you agree with what the rest of the angels are doing?”
“I’ve got my reasons,” Ariel answered.
“I’m sure you do,” Dean muttered again. “I’ve had it up to here with you angels! You keep things to yourself and refuse to acknowledge that there are actually people on this planet! People that don’t deserve to live through your infighting!”
“Dean,” Ariel said.
“I don’t want any part of it!” Dean continued.
“Dean,” Ariel tried again.
Sam placed his hand over his brother’s mouth. Dean glared at Sam, but finally fell quiet.
“I’m on your side. I haven’t been in the loop until recently. I’m sorry that I couldn’t do much before now, I was busy. I caught up with you at my first opportunity.” Ariel said sadly.
“What does that mean?” Dean asked.
“Chuck now has the ability to summon me if and when he needs me. His leash is now considerably longer now, giving me a bit more free time to do what I consider to be more important,” Ariel explained.
Dean nodded in understanding. “I see.”
Ariel waved her hands and two silver charms appeared in her hands. “If you keep this on you, you’ll be able to call on me when you need to. Keep it close.” With a flutter of wings, Ariel disappeared. Dean looked around the storage room to find Castiel gone as well.
“There is one person who can stop the apocalypse, Ariel. I don’t understand why you don’t tell him what’s going on and ask him to stop it,” Castiel said, confused.
“First of all, he’s no longer a him. She changed her name to Dawn. Right before she sent herself to the Slayer, shifted reality as if Dawn was always there, and locked her true memories away. God is now known as The Key, and is protected by a vampire with a heart, two witches, one of which is very volatile, a former vengeance demon, and a carpenter, if we exclude the robot. Dawn doesn’t know who she is.” Ariel raised her head, eyes glistening.
“Why did Dawn do that?” Castiel asked, confused. “And how do you know all of this?”
“Dawn’s motivations are her own. As to how I know this, When I was on Earth, I also protected her. My vessel is the Slayer Dawn made her sister, and arguably, the greatest one that ever lived. When Dawn arrived, and before she cleared her memory, she gave me permission to stay with her as a bodyguard,” Ariel answered.
“Dawn needs to know who she truly is,” Castiel said.
“I know, but she’s only nineteen. She’s not going to take it very well, especially if her long dead sister comes to her,” Ariel argued.
“Then maybe you shouldn’t go to her,” Castiel suggested. “What if the Winchester brothers go to her instead?”
“Go to her and do what, exactly?” Ariel asked.
“Convince her that she’s something greater,” Castiel suggested, weakly.
“The only one who she’ll believe would be me. It’s not going to be easy to find her. The first thing I did was carve her with anti-angel marks, like I did with Sam and Dean,” Ariel said.
“What is her mortal name?” Castiel asked.
“Dawn Summers. When and if you find her, bring her to me, or call me to you. I’m unsure if anyone except me can release her true memories.” With that Ariel disappeared.
Sam and Dean were standing outside of Bobby’s hospital room. Bobby was depressed and not talking to anyone. “He might never be the same again, ever,” Sam whispered to Dean.
“Yeah, I know. It just hurts to see him like that, you know?” Dean said, then held up an x-ray. “I was just over in radiology. Got a glamour shot.”
Sam took the x-ray and held it to the light. He could see the symbols that had been carved there. “You’ve got a matching set, remember?” Dean asked. Sam nodded, and his phone went off.
“Yeah?” Sam answered, flipping his phone open.
“Where are you?” Castiel’s tone was as neutral as ever.
“We’re at Saint Martin’s Hospital, room 314, why?” Sam asked. Seeing Castiel appear in front of him, Sam snapped his phone closed.
“You’re hidden from angels now,” Castiel reminded him.
“Get your ass in here and heal me up!” Bobby spun around in his wheel chair.
“I’m sorry. I’m not able to do that. I was cut off from heaven when my vessel was killed. Certain things I can do, and others I can’t,” Castiel answered.
Bitter and upset, Bobby growled “Shove it up your ass!”
Dean sighed, but Sam’s head shot up. “What about Ariel?” he asked.
“Do you think she would?” Dean asked, a little hopeful.
“We could find out,” Sam suggested.
“Who’s Ariel?” Bobby asked, still angry.
“She’s Chuck’s angel, or rather the one who protects him,” Sam answered when Dean didn’t.
“She’s also the one who brought Cas back,” Dean added.
“Ariel wouldn’t do anything because it’s asked of her. She will make you do something in return. You must be prepared to be in her debt,” Castiel warned.
“If she were going to put us in debt, why did she give us a way to contact her?” Dean asked.
“Because those were for life or death situations, not to use on a whim.” Ariel appeared behind Castiel, the top of her golden head reaching Castiel’s eye level. Walking around Castiel, Ariel stood beside Bobby. “Are you willing to do what I am about to ask ask of you in exchange for healing you of your paralysis?”
“Depends on what you’re going to ask,” Bobby responded.
“I want you to never leave these two until you have no choice,” Ariel requested.
Bobby nodded. “Wasn’t planning on it.”
“Good.” Ariel placed her hand on Bobby’s shoulder and he felt a heat flow through him before it centered on his legs. “Stay in the chair until a doctor examines you. You’re not completely healed, but you will be able to walk again.”
“Thanks,” Bobby grumbled. Ariel was gone with a flutter of wings.
“Why are you here, Cas?” Dean asked.
“I heard about your plan to kill Lucifer.” Castiel said.
“Yeah, you want to help?” Dean asked.
“No. It’s foolish. It can’t be done,” Castiel said
“Oh, well thanks for the support. What else can we do?” Dean demanded.
“There is one other being, other than Michael, that can defeat Lucifer. The one who put you on that plane. The one who began everything. I”m going to find Dawn,” Castiel said.
“Who?” Sam asked.
“Dawn?” Dean said at the same time.
“Yes. God had come down among humans. She doesn’t know who she is, and right now, she’s your only hope,” Castiel explained.
“Let me get this straight: God is a woman?” Dean asked.
“At the moment, yes,” Castiel confirmed. “I need to find her.”
“I don’t think she gives a shit about anyone on the planet, or the fucking apocalypse!” Dean shouted.
“That’s enough. I’ve killed several angels this week. Those were my brothers and sisters. I am hunted. I have rebelled and I did it all for you! And you failed. You and your brother destroyed the world and I lost everything! So keep your opinions to yourself!” Castiel hissed.
“You came here for a reason, what is it?” Bobby asked, breaking up the argument, and spinning to face Dean, Castiel, and Sam.
“What do you need from us?” Dean asked.
“I need an amulet. It’s very powerful and very rare. It will glow green in her presence,” Castiel explained.
“Like a godly EMF,” Sam concluded.
“I don’t have anything like that,” Bobby said.
“I know.” Castiel turned to look at Dean. “You do.”
“What?” Dean asked, surprised. He followed the angel’s gaze and his eyes widened. “This?” he asked, confused, holding his necklace away from his body.
“Yes. May I borrow it?” Castiel asked.
“No!” Dean exclaimed.
“Dean, give it to me,” Castiel requested.
Dean looked from the angel to his necklace twice before letting out a sigh. “Alright, I guess,” Dean said reluctantly, slipping it off. “Don’t loose it,” he commanded. As Castiel took the necklace, he muttered, “Oh, great! Now I feel naked!”
“I’ll keep in touch,” Castiel said, before flying away.
