A/N: Hey guys! Sorry for not updating sooner; I really had a busy day. But hey! It's 12:30AM and I'm uploading this for you guys! I'll update hopefully later today (since it is technically Saturday). Once again, thanks to all who reviewed last chapter: Maya Midnight Castiel, vampgirl1902, The Mysterious Shadow, skiing Pelican, Maddy Love Castiel, kittenguts, and Ooyuki-chan.

All mistakes are mine 'cuz I'm human!

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

"Really Dean, it's not that hard," the first voice says. "Give us the angel, and you can keep your brother. You do value Sam more than this angel, don't you?"

"First, his name is Castiel," Dean snaps. "And second, I value Sam and Cas equally."

"What, no favorites Dean?" The second voice smirks.

"Shut up Meg," Dean snarls. "I'll send you back to Hell."

"Now, Dean, think about this for a moment," the first voice says. "You're making this much more difficult that it already is."

Dean stares as the two figures advance forward. Meg stands in a condescending way while the Leviathan doctor stands in a calm pose.

"I'm being selfish," Castiel mutters behind Dean. "I'll go."

"The Hell you will," Dean says, turning to face Castiel. "I'm not giving you up."

"Your brother is more important," Castiel argues. "Always has been, always will be."

"At least the angel understands," the Leviathan doctor grins.

"Stop trying to be the hero Cas!" Dean yells, looking on the verge of breaking into tears. "Let me save you for once."

"Lucifer says it's for the best," Castiel says, looking at Dean sadly.

Dean turns back to Meg and the Leviathan doctor. "I can't pick."

"Fine," Meg says, "let's make it easier. We get Sam and Cas."

"Or," the Leviathan doctor says, walking up to Dean, "we take him."

"No!" Castiel snaps. He stalks forward, a low growl forming in this throat.

C'mon Cas, the voice purrs. Show them what you can do. Destroy them!

Meg's face turns a trifle frightened. Castiel bares his teeth, the feeling of losing control taking over.

Show your wings, the voice coaches. Show them your power.

"You shouldn't have come," Castiel says gruffly. The bedroom door slams shut and the lights begin to flicker rapidly. In a flash, black wings appear behind Castiel, large and fluffed out.

"Any last requests?" Castiel grins. "Or should I kill you two now?"

Meg glances at Dean, horrified, but Dean is staring in shock at Castiel.

Do it, the voice says. Kill them now.

Castiel hisses and lashes out, pointed claws grasp at Meg, latching on to her throat.

"But…I helped you," Meg squeaks.

No mercy, the voice whispers impatiently. Finish the demon.

Castiel stares coldly at Meg with red eyes and then slashes her throat completely open, all the way down her stomach. Blood pools on the floor as Meg falls to the ground.

Now the Leviathan, the voice says. With my power, you can kill him.

Castiel turns to the Leviathan doctor and stalks forward.

"You can't kill me," the Leviathan doctor says, trying to fight of fear.

"Yes, I can actually," Castiel grins and grabs the Leviathan doctor by the shirt. "And I'm going to tear you into pieces."

Dean stares in horror as Castiel rips the Leviathan doctor over and over like it was nothing. Worst part was, the angel was enjoying it, but Dean knew it wasn't really Castiel doing it-it was whatever was controlling him.

Castiel looks down at the torn up corpses, satisfied.

You still have one more to kill, the voice says.

Castiel turns to face Dean, who stares back.

You failed once, the voice hisses in a disappointed tone. So do it now.

Castiel advances forward every time Dean backs away.

"Cas?" Dean says. "This isn't you."

Pathetic attempts, the voice says. Kill him.

Castiel stares at Dean, wanting to obey the voice, but there was something about the guy in front of him that made Castiel freeze.

"Cas, please," Dean begs, shaking. "You wouldn't hurt me."

Castiel frowns and tilts his head. He knows this person.

Kill him! The voice screams. You've got to learn who to listen to!

Castiel growls and walks forward, grabbing Dean by his shirt.

"Cas," Dean says, eyes wide. "Don't you know me anymore?"

Castiel's eyes widen. Terrified green eyes stare back.

Stop wasting your time! The voice yells. Listen to me!

Castiel growls and throws Dean across the room. He huffs and walks over to Dean laying on the floor.

Go ahead, do it, the voice says. Do it!

Castiel picks Dean up by his shirt.

"Cas," Dean repeats. "Please, you need to stop."

Castiel stares at Dean, eyes narrowed.

"I know you," Dean says. "Whatever is controlling you, you need to overpower it."

Castiel's grip looses but Dean doesn't pull away like he thought he would. Instead, Dean grabs Castiel and pulls him into a hug.

"You can do this Cas," Dean says. "Please, do this for me."

Castiel frowns.

No, listen to me! The voice hisses. Not to him.

The scent of Dean comforted Castiel though, and he wanted nothing more than to get rid of the voice. Castiel shuts his eyes and wills the voice away, letting out a hiss of pain.

"Cas?" Dean asks after a moment.

"Thank you Dean," Castiel sighs, burying his face in Dean's shoulder.

Dean gives a nervous chuckle. "I was afraid you wouldn't listen."

Castiel pulls away to look at Dean. "I will always listen to you," Castiel says, staring earnestly at Dean.

"I hope I can believe that," Dean replies.

Castiel tilts his head and then runs a hand through Dean's hair. "You're hair is very complex."

Dean stares at Castiel. "Um… how so?"

Castiel smiles. "The texture is interesting."

"Well, y'know, you can always use the same shampoo as me," Dean jokes, giving a nervous smile.

"But I do not need to take showers," Castiel says.

Dean shrugs and then stares behind Castiel's back. "You know your wings are showing still right?"

"I'm aware," Castiel says, and then closes his eyes. A bright light shines and then his wings are gone.

Dean sighs. "I'm glad you're okay."

"You keep saying that," Castiel says.

"Well, I mean it," Dean replies. "I get worried every time something happens to you."

"You do?" Castiel asks.

Dean hates how his face feels hot. "Yes."

"Dean!" Sam yells, rushing into the room. "You okay?"

Dean turns to face Sam. "Yeah, I'm fine. How about you?" Dean asks. "I heard they kidnapped you."

"No," Sam frowns. "I came up here because of the commotion."

Now Dean frowns. "You sure?"

"Of course I'm sure," Sam says. "What happened?"

Dean shakes his head. "I'll tell you downstairs," Dean says, waving a hand. "I'll meet you in the kitchen."

Sam stands hesitantly for a moment, but then exits the room.

After a moment, Dean says, "How could have Sam not known?"

"I would hate to be judgmental of your brother Dean," Castiel says, "but maybe he was a part of this."

Dean frowns, not liking the idea one bit. "Yeah, well, we'll find out soon enough, won't we?" Dean turns to Castiel. "C'mon buddy, let's go." Dean pulls on Castiel's shirt to pull him closer. "Don't leave my sight."
