A/N: Hey everybody! Time for another update! Once again, senior don't have to be at school until noon, so I'm taking this chance to update :D Today might even be a double update again because I love you guys that much ^^ And because I truly do love writing this story. Thank you to those who reviewed: The Mysterious Shadow, CandySmile, roxxroj, skiing Pelican, and Maddy Love Castiel. Your reviews make me happy ^^

This chapter will be a little different, and I hope it's okay ^^; roxxroj asked me to do a chapter in Castiel's perspective seeing Lucifer, so I hope this chapter will suffice. Next chapter will go back to Dean, but I might throw in a couple more Castiel POV chapters. Any mistakes are mine because I'm human!

Alright, I believe that is enough rambling. Let's get onto the story, shall we?

Disclaimer: I do not own Supernatural, nor do I own any of its friggin' characters, though I wish I did.

"Me, myself, and I think you're looking a bit lonely there, brother," Lucifer says, sitting on Dean's chair while Castiel sits on Dean's bed. Castiel glances at Lucifer and then turns away. Honestly Castiel wished it would end, but he had made a promise to Dean to make it till Sunday. Sunday was too far.

"How about a bedtime story?" Lucifer asks. "I could read you The Hobbit, or maybe Hamlet."

Castiel groans and lies down on the bed, putting the pillow over his head.

"You know, the best way to go deaf is to cut your ears off," Lucifer comments.

That didn't seem like a bad idea to Castiel at the moment. The lights in the room flicker on and Castiel feels the pillow being taken off his head.

"Cas?" Dean asks, a puzzled look on his face.

"Hello, Dean," Castiel mutters, sitting up.

"Do you think I should talk to Sammy boy?" Lucifer asks. "At least he talked to me for a while."

Castiel twitches and chooses to look at Dean instead.

"Cas?" Dean asks. "You okay?"

"Yes," Castiel replies. "What do you need?"

"I wanted to check up on you," Dean says. "You had me frightened after what happened earlier, so I wanted to check up on you."

"I did not mean to scare you, Dean," Castiel says, glancing up at Dean. He didn't know what had happened exactly in the living room. Castiel frowns and looks at the ground. The voice he had heard hadn't been Lucifer's.

"I can tell you what happened," Lucifer says. "Very ingenious thing that doctor put in your drink."

Castiel narrows his eyes and then stands up.

"Cas?" Dean asks, backing away.

"I know you want to know," Lucifer grins. "So why not let me tell you? Though, to be honest, what he put in your system isn't something you can get rid of so easily."

Castiel did want to know what it was, but he didn't want to talk to Lucifer. Castiel turns to Dean instead, glancing at his shoulder. Castiel places a hand on Dean's shoulder and a bright light shines. Castiel takes his hand away and Dean looks to see his shoulder healed.

"Thanks," Dean says.

Castiel nods in response, not sure what do to. He glances around the room, but finds no books. "Do you mind if I read a couple of books?"

Dean blinks. "Sure, if you want." Dean makes a motion for Castiel to follow. The two head to the library where there were stacks of historical books collected by Bobby. "If you need anything, holler, okay?"

Castiel nods and then sits down at the table already piled with books. He looks up to see Dean still standing there and tilts his head. "Do you need something?"

Dean seems to snap out of his reverie. "Uh, no. I was just making sure you're settled." With that Castiel watches Dean head out of the room.

Castiel turns his attention to reading books.

"You know, there is no book in learning how to become sane," Lucifer says, leaning against the bookshelf.

Castiel snorts and continues to flip through a book on mythology.

"You know what's really dangerous though?" Lucifer says, walking up to Castiel. "Sam. He triggers that drink you Cas."

Castiel stops reading but keeps his eyes on the page.

"So, my advice is, if you don't want to go back to that hole, you don't look at Sam," Lucifer says. "To be honest, I don't like whatever this is either because it pushes me away."

At that moment Sam chooses to walk in. "Hey, Cas."

Castiel freezes, eyes wide, but doesn't look up. "Hello, Sam." It comes out bitter, but he can't help it.

"Don't look at him," Lucifer sings, walking back to the bookshelf.

Sam frowns. "What are you doing?"

"Reading," Castiel says curtly. "I need something to do."

"Oh," Sam says. "Well, I was wondering if you want to help me with a case I'm working on."

Castiel leans back in the chair, still keeping his eyes off Sam. "On what?"

"It's a witch that's in a nearby town," Sam says. "She puts a spell on people that make them go crazy for two weeks."

Castiel snaps, anger rising in him. He stands up, still not looking at Sam. "Are you saying you want me to help because I can relate to this?"

Sam blinks, taken aback. "What? No… I just thought since Dean's working on his own thing…"

"Forget it," Castiel growls, and starts to exit the library. "I'm not in the mood to help you, Sam."

"Wait, Cas," Sam says, trotting to catch up to Castiel. "Look, I'm sorry for upsetting you, but I didn't mean it like that." Sam turns Castiel around, who keeps his eyes to the floor. "Why won't you look at me?"

"I just can't," Castiel answers. "It triggers something in me."

Sam frowns. "What, like earlier?"

Castiel nods. "Sorry, Sam," Castiel says and then walks away.

"That's my brother," Lucifer grins, walking beside Castiel. "Good job."

Castiel growls and shoves Lucifer aside. "Leave me alone," Castiel says and opens the door to head outside.

"Wait, Cas, where are you going?" Sam asks from behind him.

"I believe the term is 'getting some fresh air'," Castiel says, and walks outside.

"Wait, Cas, one more thing," Sam says, following Castiel. "What… I mean… how is it, with Lucifer?"

Castiel pauses, glancing at the sky. "Some days are better than others," Castiel replies. "Some days it's just Hell."

"Hell is Home," Lucifer says. "And it should be yours too, brother. Just think, at least I wouldn't cast you out." Lucifer grins and then goes off to start singing "When the Saints Come Marching In."

"Well, uh, just know that if you want someone to talk about it, I'm here," Sam says.

Castiel nods and looks at the ground. "I'll keep that in mind." He turns his head to see Dean walking out of the house.

"Why's everybody out here?" Dean asks, staring at Sam and Castiel. "You're not doing anything to him, are you Sam?"

"What, no!" Sam says. "I was just talking to him."

"I'm fine, Dean," Castiel says and looks at Dean, grateful that he at least had someone he could look at.

"Oh Sammy! It's so good to see you!" Lucifer says, walking around Sam. "Long time no torture, huh?"

Castiel jerks his head in Sam's direction, but keeps his eyes of Sam.

"What is it?" Sam asks, looking around him.

"Hey Sammy, how about I show you a little bit of art?" Lucifer says, taking out a knife.

Castiel growls, narrowing his eyes.

"Cas, what's going on?" Dean asks, looking between Sam and Castiel.

"Leave him alone," Castiel says, advancing forward. "You're done with him."

"Oh, but I'm not," Lucifer says. "We still have a connection you know."

"Cas?" Sam asks. "Is it Lucifer?"

"Oh hey Sammy!" Lucifer grins and waves his hand in front of Sam. "Pity you can't see me."

"Go away from him," Castiel warns.

"You can't do anything against me," Lucifer says. "Sorry, brother." Lucifer raises the knife to Sam's throat.

Castiel lunges forward, surprising both Sam and Dean. Castiel punches to what Sam and Dean see as air, but he hits Lucifer square on.

"I really wish you weren't a nuisance," Lucifer says, making a 'tsk-tsk' sound. "I'm trying to communicate with Sam."

"You stay away from him," Castiel says, standing in front of Sam.

"Try me," Lucifer grins, and then disappears, only to re-appear behind Sam.

Castiel turns to look at Lucifer, but in the moment forgets not to look at Sam. Their eyes lock and Castiel feels his breath hitch.

"Oh god," Sam says.

"What? What's going on?" Dean asks, standing beside his brother. "What?"

"Dean, quick, do something!" Sam shouts, pointing to Castiel.

"What's happening?" Dean asks. "What happened? All he did was look at you."

"Yeah, and apparently it triggers something in him," Sam says. "Like earlier."

"Damn it," Dean growls and runs over to Castiel. "Hey, Cas?"

Castiel feels his vision cloud, even though he can hear Dean speak. He wants to talk back, but he can't.

Finally, once again, the voice says. Last time was too short. What says you we get a move on, huh?

Castiel feels his willpower to resist drain and can only nod in agreement.

"Cas?" Dean asks, shaking the angel. "Hey, Cas!"

Start with him, the voice says, meaning Dean.

Castiel hisses, his eyes turning from blue to red and Dean stares back, eyes wide. Castiel grabs Dean by the collar and grins.

"Cas?" Dean asks, his voice faltering. What if this was the point that Castiel was right-that he wouldn't remember him anymore? How was he supposed to save his angel?

A/N: Yes! Chapter complete! I feel proud this is mostly a free-written chapter, but it's a long chapter! :D I didn't expect it to be this long, but still! I hope you enjoyed it! Now things are getting interesting! Don't forget to drop a review!

On a side note: I can't believe it's almost May! That means I'll be done with high school-forever! I'm going to miss all my friends terrible T_T But I get to start college! We're going to move into a house finally, and I'll have my own room. As soon as I do, I'm so decorating my room with all Supernatural stuff :3

Until next time! *salutes*
