A God Am I: Light of course and Duck. He decides he likes Naomi's paranoid theory that he's the spawn of the Notebook because 1) that means Light had less to do with his genetics and 2) that means he's more of a "God" than Kira could ever hope to be.
Dressing as the Enemy: When the police are banging down the door Matt and Duck attempt to disguise Mello. Matt resorts to drugging Mello in order to make him lose the stripper costume, cuts his hair and forces him into a suit and tie. Naomi comments in her Internal Monologue that it makes him look like Misa's little brother that likes dressing up like Light.
Faking the Dead: L doesn't let his successors know he is still alive because he doesn't want to have to talk to them.
Fate Worse than Death: Naomi gets angry when Raye goes missing and Light and Duck aren't concerned. She issues the following threats to get them motivated:
Naomi (to Light): ...when I kick you out that's where you're going! Roommates with Misa and Ryuk!
Duck: Why haven't we done this before?
Naomi: Shut up I'm not done with you either, if you don't procure his body you'll be forced into elementary school years before your time and I'll make you bring Light Yagami to parent-day so you can profess what a wonderful relationship you have.
Near's Agent: I can't just leave without [the notebook]!
L: Certainly you can, just say Light Yagami gave you the run around and that his soldiers were undyingly loyal. Also tell him that we just don't trust you. Near will buy that.
Near's Agent: Are you framing one of your employees?
L: It'd be framing if there was any way to convince Near that Light was not in fact Kira and somehow not giving you the run around. You don't have to tell him that Light wasn't actually here and never actually met with you.
Freudian Excuse: "The Beyond Birthday case made so much more sense now, BB wasn't a megalomaniac he was L's spurned and neglected lover. Clearly the jam was just the aftershock of being forced into sex with someone that looked vaguely like a crack head. And she had prevented him from burning himself alive, if she had to have sex with L she might have tried to burn herself alive too. Naomi noted to herself that perhaps it was a good time to go to L.A.'s prison and apologize to that poor madman."
Light: I think your successor thinks we have the combined I.Q. of Matsuda.
Matsuda: You guys know I'm right here.
Ignored Enemy: L, Naomi, and Mello get into an arguement in which Mello outs himself as the one and only transvestite terrorist-and becomes very miffed when neither L nor Naomi care enough to stop bickering because of it.
Naomi: [S]ince you keep claiming to be God this must somehow be your fault.
Light: I'm not sure that's how god complexes actually work, Naomi.
Irritation Is the Sincerest Form of Flattery: "The team looked at L who looked about ready to shoot himself at the fact that his successor had stolen his entire get-up. At least Mello had the decency to become a transvestite mafia lord for the sake of originality, Near was just a sad little chip off the old block."
Law of Inverse Paternity: Duck and Light hate each other. Much to Naomi's disgust, Duck would rather have Ryuk as his father and he quickly latches onto the idea that he's the Anti Christ spawn of the death note as a more favorable alternative.
LEGO Genetics: Naomi theorizes that Light was mutated by his heavy notebook usage and that he passed that mutation onto Duck.
Duck: Right, well I asked him to find Schrodinger's Cat, he misunderstood the directions. I hope you like cats, he just keeps bringing them, I almost want to tell him to stop but I also want to see how far he's going to take this before he gives up. He's very tenacious for a half-wit.
Mike Nelson, Destroyer of Worlds: If anyone is going to destroy the world it's going to be Matsuda. Later Light tells L and Naomi that Kira told him that he has "misplaced" a Death Note.
Naomi: Are you saying that we lost the notebook and that no one noticed? How could you lose something like that? That's like Roosevelt losing the atom bomb, woops it got stolen, guess we'll have to write that one off.
Mistaken Identity: Mello and Matt are brought to the Taskforce in a simple disguise. L, who never cared enough to know who the Wammy's kids were apparently buys their lame excuse, does not recognize Mello at all (instead insisting he must be Matsuda's character Hikaru Imagay brought to life). Similarly Mello has yet to realize that Ryuuzaki is his beloved L and takes to calling him "crackhead."
Mook-Face Turn: Naomi talks to and bonds with Bubba over the fact that Mello dresses like a male prostitute.
Morality Chain: Naomi realizes, to her horror, that she is Light's Morality Chain and so keeps hanging out with him even though he is a Serial Killer, her creepy stalker, and a jerk because he could be so much worse.
Light refers to Raye Penber as "the Wallpaper" and Naomi's son as "The Curtain."
Duck refers to L as "Uncle Pedophilia and Light as "Ted Bundy". Duck also renames Wammy's House as "Wammy's Dog Fighting Arena for Boys" and gives Mello and Matt new aliases- Mello is "F" (either for "Frodo" or "Failure" his choice) and Matt is "D" (either for "Dracula" or "Doormat" again, his choice).
No Social Skills: L, of course. "L had an annoying habit of speaking very loudly on his cellphone as if his conversation was far more important than anything anyone else could be doing. That or Watari had managed to teach L no social etiquette at all, maybe he hadn't bothered. L could have been a lost cause from the get go."
Riding into the Sunset: parodied on Matsuda's soap opera "The Boogeyman" where the Great Detective Y rides off into the sunset, again not bothering to tell anyone his name, and leaving his spurned and neglected lover Hikaru Imagay behind.
Naomi: [Most people] believe that man is essentially good and ride upon that faith throughout life.
Duck: That's a silly thing to believe. If I believed in the essential goodness of man I'd be Kira too and we certainly don't need two of those.
Naomi: Duck, Kira is a serial killer who believes he kills the irredeemable scum of the earth. I don't think he should be your role model of men who have faith in humanity.
Duck: He wouldn't bother if he thought there was no chance of redemption, he believes that most people have that spark of goodness in their hearts and only some are the scum of the earth. If he thought that all men were worthless he'd either do nothing or he'd just kill everyone.
L If you're finally going to admit that you're Kira I'll have you know that so far your various futures entail your being my sex slave, the government's sex slave, or locked up in some mental institution. Of the three I prefer your being my sex slave but the decision is yours. Or Naomi-chan could shoot youbehind the chemical shed, if that's preferable.
L So really the only options that we have left after we prove that Light is Kira are for him to be my personal sex slave or to be shot behind the chemical shed. Prove to ourselves at least, I don't think we'll ever convince Soichiro or Matsuda even with the thirteen day rule. So Light since this is your immediate future which would you prefer, death or sex slave?
Naomi: You do realize that if L or Kira were to find out they would kill you... If Light finds out he'll probably kill you. However he might keep you around as a pawn and use you to reach his ultimate goal of creating a cult civilization in which he's god. That means that if you don't find yourself drowning in a swimming pool you'll find yourself brainwashed and tortured and then thinking nothing at all... If L finds you that's a whole different story. L won't kill you but he will tie you to a chair and leave you there to rot for fifty days and then pretend to execute you only to leave you alive so that the government can perform nasty experiments on you. He probably won't give you a trial but instead will leave you in a mental institution or have you killed off by thugs. Then he'll steal your name and use it as yet another detective name and that will be the end of that.
For some reason Naomi found herself thinking of The Godfather, and the horse's head tossed into a bed. Except the horse's head was Matt's and it was Mello's leopard printed waterbed that was soaked in blood.
Matsuda: Well, Inamo it turns out had an affair with Y's evil twin A and that A is now back in town but Y doesn't want Hikaru to know because he's afraid that A will seduce Y because they're identical and it's really hard to tell them apart.
Light: And let me guess Hikaru is going to sleep with both of them because he's not only gay but he's also a whore.
Matsuda: Um, well, I don't know if I'd use that term but what if he really can't tell the difference and then… Wow Light, you have really good ideas! You should help me write sometime!
Light: You know, this is excellent proof that I'm not Kira. Ryuzaki may be miserable and death-seeking but if I had been Kira then surely Matsuda would be dead by now.
Something We Forgot: Between dealing with Light and L and her son it takes a week for Naomi to realize that Raye has been kidnapped.
Spit Take: Naomi with her coffee, repeatedly when Duck is asking about his parentage... and suggests that he really wanted Ryuk to be his father.
"Light had been extremely careful and it would have been ridiculous to jump to the conclusion that he killed via notebook rather than magic bath towel. For months L had been convinced that Light had killed via bath towel, or magic shower soap, or just showers."
Sunglasses at Night: Matt wears goggles indoors, in the dark. Naomi "supposed that since it was goggles it hadn't offended her as immediately as sunglasses would have but he still looked like a tool."
Surrounded by Idiots: Light and L feel this way and Naomi Misora realizes she's Surrounded By Lunatics.
Take That, Audience!: or Take That Fandom. The Meta joke of Matsuda's soap opera, staring Hikaru Imagay the gay prostitute.
The Friend Nobody Likes: Misa and L are this for the taskforce. L feels this way about Near and Mello and makes Light talk to Near because he doesn't want to talk to him or even let him know he's still alive.
Light's parents attempt to make him seek help from a therapist when his mental issues begin to become obvious after blatantly stalking an older woman and her fiance, crashing at their place, and refusing to leave. Light's parents concede that their son MIGHT just have a problem and should probably get help. Naomi notes that it's a coupleof yearstoo late. Nor is there any therapy available for all the times L drugged and had his way with Light. But L did give him a gun...
They Would Cut You Up: L points out that even if he arrested Light as Kira the world governments wouldn't execute him right away. They'd want to study him first to see what effects long-term usage of the notebook has on a human body...
You, Get Me Coffee: this is usually Matsuda's job but when L gets annoyed with having to deal with Near's minion and goes out to get his own coffee. That's when the taskforce mutinies in the hopes of making L's coffeeboy-status permanent.
Your Cheating Heart: Misa is Light's "girlfriend" but Naomi is the only one that Light has an active interest in (despite not having a sex-drive). Naomi slept with Light once and he knocked her up. Naomi gets married to Raye while Light continues to stalk her, and meanwhile L continues to stalk Light.
