AN: Oh. My. Cas. I have not updated in so long, I'm sorry fans of this surprisingly beloved fic, I will give you an extra good chapter this time, I promise.

At the motel, Castiel had finally returned to Sam and Dean, who were confused about where he had gone.

"Have either of you two ever heard of a Shinigami?" he asked both of them.

Sam and Dean both stared at him with their eyebrows raised before Sam finally asked, "What's that and why do you ask?"

"A Shinigami is a Japanese god of death, in particular, they use notebooks to kill their enemies by writing their names," Castiel replied.

Dean just looked at Castiel, "You didn't answer the second question...Why do you ask?"

He sighed, "The two men next door have one following them around, which means that one of them has a Death Note."

"I didn't see anything abnormal," Sam said.

"And what's a Death Note?" Dean asked.

"You can't see a shinigami unless you're holding a Death Note that used to belong to it or if you're an angel, and a Death Note is a notebook that kills anyone whose name is written in it," Castiel was talking quickly now.

"What's the importance of telling us all of this?" Sam asked.

"I happen to know that there is someone on this world now known as Kira who kills criminals with heart attacks, a heart attack is a Death Note's most simple method of killing someone."

"Wait, heart attacks in criminals? Isn't that exactly the thing we're looking for? How did we not guess that it was Kira? We've heard all about him!" Dean exclaimed.

"One of those men is Kira?" Sam asked, "We can't have narrowed things down more than L so quickly, he's the world's greatest detective."

Dean looked straight at Sam, his eyes were wide, "What if the one of them that isn't Kira is actually L? Or maybe Kira is L."

Castiel felt left out of this conversation.

"Dean, that's ridiculous, L and Kira would definitely never be in the same room as each other, L would just know. Also, L couldn't possibly be Kira, that would just be confusing," Sam looked slightly irritated.

"Sam, I'm pretty sure that L doesn't have amazing psychic mind-reading powers, he could easily not know if Kira was next to him," Dean was irritated too.

"L is probably the pale one, Cas did say that he was a detective," Sam decided to change the subject.

This might sound surprising, but this conversation got pretty boring, so we might as well see what L, Light and Ryuk are up to.

Ryuk felt like he was being tortured, he hadn't eaten an apple in days, so he was standing on his hands while L typed away, researching the two "FBI agents" they had met yesterday, he had only discovered their superior.

L dialed the number he had retrieved and there was a gruff sounding, "Hello?" coming from the phone.

"Hello, this is Eraldo Coil, can you tell me about the men known as Sam and Dean-"

"Yes, they're both completely legitimate, now leave me alone," the man hung up.

For the first time ever, someone had cut L off, how dare he?

"It sounds like that didn't go too well for you," Light said.

"It is quite obvious to me that the man on the other end of that phone was not legitimate either," L place 5 truffles in his mouth at once, chewing them into pulp in seconds.

"What makes you say that?"

L starting dropping sugar cubes into his tea, "He was far too gruff sounding, and he interrupted me, no FBI agent would be rude enough to interrupt Eraldo Coil, the world's second greatest detective."

Light still didn't understand how L hadn't had him killed for being Kira.

Ryuk felt like he would die if he didn't get an apple soon.

"I would say that there is a 42% chance that one or both of those two men are Kira," L started sipping at his sludge.

Light felt an odd compulsion to grab it and dump it on L's head, but he resisted.

Meanwhile, in the next room, Sam hadn't resisted wanting to smash a pie into Dean's face, and Dean had pie all over his face.

"You suck," Dean sounded angry.

"Why would that brown-haired one be L?"

"Why not?"

Sam didn't want to get involved in this argument again, there was no more pie to put in Dean's face.

Dean walked into the bathroom to wash the pie off of his face.

Castiel had stood in silence for 15 minutes while Sam and Dean were arguing.

"So, yes, one of those two is most likely Kira, I'll have to talk to the shinigami to find out if either of them are, and possibly even which one," He said.

"Okay, so do that."

Castiel sighed again, "I can't do that right now, a shinigami can't be easily separated from the holder of a Death Note."

"How long will you need?" Sam asked.

"3 hours, and I think that the one that's Kira will notice their shinigami missing, so this might be the worst possible plan."

"Oh, okay," Sam turned on the TV as Castiel cleared the table off and started chanting and carving things into it.

3 hours later

Castiel had succeeded in separating Ryuk from Light for 2 hours, and had taken him to a warehouse.

"Are either of the men sharing that room with you the criminal known as Kira?" Castiel asked.

Ryuk looked at him and chuckled, "I won't tell you anything unless you give me apples."

"Apples?"

"Yes."

Castiel disappeared for a few minutes and then returned with a large sack full of bright red apples.

Ryuk immediately started eating the apples, "Yes, one of those two men is Kira."

"Which one?"

Ryuk chuckled again, "Why don't you answer my question? How can you see and hear me?"

"I am Castiel, the angel of Thursday."

Ryuk couldn't stop laughing, this man thought he was an angel!

"What's so funny?" Castiel sounded slightly angry.

"Angels don't exist."

"If we don't exist, then explain how I can see and hear you, and also how I got those apples."

Ryuk could only think that he was a shinigami as well, but he was far too attractive and that L and Light were able to see him, "If angels exist, then so do werewolves."

"Werewolves do exist, shinigami," Castiel decided to ask a question, "What is your name?"

"Ryuk."

"You didn't ask a question after that answer," Castiel was starting to walk around Ryuk in a circle.

"Where did you get these apples?" Ryuk ate 3 more apples.

"I stole them, of course. Which of those two men is Kira?"

"I can't answer that," Ryuk ate 2 apples.

"Why not?" Castiel sounded confused and angry.

"I don't want to," Ryuk laughed.

Castiel had his angelic blade in his hand, which just made Ryuk laugh harder.

Castiel jumped forward and slashed the blade across Ryuk's chest.

Black blood dripped onto the floor from the wound, "But...you can't injure a shinigami."

"You can with an angelic blade, or death's scythe, or The Colt."

Ryuk was surprised, he hadn't known he could be injured.

"All of those things can also kill you," Castiel looked grim.

"So I should answer any of your questions?"

"Exactly."

"I can't tell you exactly which one is Kira, but I can tell you that Kira's name begins with an L."

"That doesn't help at all," Castiel raised his blade as Ryuk finished the apples.

Ryuk wanted to leave, he'd been here for 2 hours and didn't want to die, so he decided to start flying away, not sure if that would work.

It did.

Castiel couldn't have been more angry, but he couldn't get Ryuk back, so he returned to the Winchesters.

"One of those men is Kira and the shinigami's name is Ryuk."

"Cas, you've been gone for 2 hours and Sam wouldn't tell me where you were," Dean looked irritated.

"I didn't know where he was!"

Castiel sighed, those two fight too much.

Light would need to ask Ryuk where he'd been as soon as possible, but he couldn't ask right now or L would hear him.

AN: That was a pretty good chapter, I think, I should have another good one up soon, I'm not sure what'll happen, maybe Dean and L will bond over pie, Castiel and Ryuk might fight, or maybe Light and Sam will become friends, you'll find out in the next chapter! Oh, and please review.
