[[WMG: Ellie Brass asked her dad to kill her]]
He was [[OOCIsSeriousBusiness oddly upbeat]] after talking to her for a few hours after her suicide attempt, which in TV dramas is a sign he's going to do something drastic. There's several reasons [[ThanatosGambit why Ellie would want Brass to kill her]]:
* Can't suffer in jail if you're dead
* BetterToDieThanBeKilled -- assuming the attempted murder of Brody, the murder of her boyfriend/"kidnapper" and her mother, and whatever else happened in the episodes I missed is enough to earn the death penalty
* If he kills her he'll feel enough guilt to kill himself, and if he doesn't he'll have to suffer with the knowledge that he failed his daughter so badly forever
* [[{{Revenge}} Killing her will "square" her killing her mother]]
* Is really just tired of living, the above reasons are just a bonus

[[WMG: The CSI universe is the past of the ComicBook/JudgeDredd universe.]]
The multi-dutied [=CSIs=] will eventually gain more and more responsibility legally, until they are the polydutied, fascist Judges. Grissom will obtain immortality and become Judge Dredd.

[[WMG: All three shows are set Main/TwentyMinutesIntoTheFuture.]]
More like five to ten, really - but this explains both why the Main/AppliedPhlebotinum is so much faster and more reliable than its real-world equivalent and why procedures have changed to allow CSI techs to conduct full investigations, interrogate suspects, and so forth. The Vegas show is set a few minutes ahead of the New York show. Miami is set a bit ahead of them both, even though Miami and New York have crossed over a few times. There was an episode of ''CSI: Miami'' with a weapon that could shoot [[Main/{{BFG}} a few hundred bullets at the same time]]. This could also explain why the Miami team's use of a Hummer H2 instead of, say, a Ford Focus wagon or a cargo van, doesn't lead to a taxpayer revolt. By that time, a used H2 will be the cheapest vehicle of any type available- [[Main/TakeThat it's well on the way now]]. The ''gas'' for it, on the other hand...
* Gas? What gas? The team Hummer has undergone conversion to run on alcohol-- takes about ten minutes with a needle-nose pliers and a stiff wire.
* CSI:Miami's actors have claimed that the Miami spinoff is a "comic book world".
** That would make all of the shows comic books, since they've all crossed over.
* Maybe this is also why the Crime Lab people have so much more power (in terms of [[JurisdictionFriction jurisdiction]]) than their contemporary counterparts do.
* Bizarrely, this makes a lot of sense.
* Remember also that in the CSI-verse, the [[http://en.wikipedia.org/wiki/Cumbre_vieja Cumbre Vieja]] volcano ''did'' explode, causing a megatsunami that flooded Miami. The Canary Islands probably don't exist anymore.
* The hundred-bullet gun is a real concept with working prototypes. The fact that only prototypes exist now in RealLife, however...

[[WMG: All three shows are set in the Franchise/StargateVerse.]]

Consider CSI: NY's hologram room and the examples above. It's all a result of the SGC slowly leaking advanced technology into the public sphere.
* Perhaps it takes place in the SG:A alternate universe in which one Detective Sheppard investigated a series of murders committed by a Wraith in Las Vegas.
* That would explain how they can afford to build spaceships and set up bases on alien worlds. That would show up in the budget unless someone set up companies to sell alien-derived tech.
* The [[OurVampiresAreDifferent vampire fans']] scars looked like suckers.

[[WMG: Sara Sidle didn't leave on her own accord; Ecklie forced her out.]]
Think about it: Ecklie was the biggest opponent to her and Grissom's relationship, and he even threatened to can both of them if they didn't stop. While there's no doubt the Miniature Killer incident shook her up something fierce, it's doubtful that she'd completely abandon her relationship to Grissom - the one thing that made her feel safe and secure - because of it; in fact, part of the reason she changed shifts was to help her recover. The complete 180 of her going from "we can handle this together" to "Main/ThisIsSomethingHesGotToDoHimself" is too coincidental to be spontaneous on her part. Hence, Ecklie must've pressured her into retiring to put an end to the relationship and strike a blow against Grissom.
* Now she's back.
** Still, the obvious tension between them in the opening of [=S10E03=] adds weight to this, even if Ecklie was the one to bring her back in. After all, he's been gunning for her ever since Season Five, when the only thing stopping him getting rid of her was Grissom's refusal to fire her. At this point, he wants to humiliate her.

[[WMG: Gil Grissom is a superhero. His superpower is competence.]]
In other words, he literally ''can'' do anything he puts his mind to, often without any formal training, at a moment's notice. He even made a makeshift crime scene kit once using mechanical pencil lead and tinting film. He even has an AlliterativeName.

Sara Sidle is also a superhero. She, however, refuses to accept her powers, which is why she is alternately fascinated by and despising Grissom. Eventually, this leads to her breakdown and departure.

Grissom also eventually leaves to attempt to help her come to grips with her powers. Since his superpower is competence, he succeeds.

[[WMG: All CSI teams have a ManBehindTheMan who's running the show. ''All'' shows.]]
And (you'll probably see this coming) it's none other than [[Manga/DeathNote L]].
* Adding to the above theory, the [=CSIs=] are orphan's of Wammy's House.
** Gil Grissom = G.
** Catherine Willows = C.
** Nick Stokes = N.
** Greg Sanders = S.
** Riley Adams = R
** Sara Sidle = S2.
** [[strike:Warrick Brown = W.]]
** Jim Brass = J.
** Al Robbins = A.
** David Hodges = D.
** Horatio Caine = H.
** Calleigh Desquene = CD.
** Eric Delko = E.
** Ryan Wolfe = W.
** Frank Tripp = F.
** Natalia Boa Vista = V.
** Mac Taylor = T.
** Stella Bonasera = B.
** Danny Messer = M.
** Dr. Sheldon Hawkes = Dr.
** Donald Flack Jr. = DF.
** Lindsay Monroe = LM.
** Jennifer Angell = JE.

[[WMG: Horatio Caine is an [[Film/TheMatrix Agent]].]]
Think about it. Sunglasses and dark suit - check. Deadpan line delivery - check. Ability to conjure items from Hammerspace - check. All he needs is a desert eagle and the ear piece.
* Never sweats in any heat. No voice inflection. Conveys an attitude of smug superiority and general contempt for mankind. Stiff and humorless personality. And he creepily materializes out of thin air.
* So ''that's'' why Morpheus went to [[Series/{{CSI}} Las Vegas]]: he wants to pump Catherine Willows for info!
* This simply has to be canon. He even looks exactly like the agents did in the first movie, redheaded and extraordinarily pale despite living in a constantly sunny locale.

[[WMG: The [=CSIs=] are serial killers.]]
They are way too successful and encounter way too many murders. And way too often, there turns out to be a connection between them and the crime. The secret is obvious: THEY are the perpetrators. Being [=CSIs=] gives them the perfect cover to manipulate the evidence and show off implausible 'enhanced' computer mockups to demonstrate their preplanned stories. Ecklie's the only clean CSI, and he has his suspicions. The series is from the perspective of their defense testimony.
* Wait, wait, if that's the case, then how do you explain the events from "Grave Danger"?
* Someone had a feud with the [=CSIs=] because they jailed his relative. Or there's more than one group of assassins in town.

[[WMG: ComicBooks of Series/CSIMiami are on sale elsewhere in the Series/CSIVerse]]
CSI: Miami is set in a comic book world. That means there must be comic books of it. If we're lucky, they'll reach the real world, and we'll soon see them tucked near Buffy Season 8 and Angel season 6... Or is that if we're unlucky?
* [[http://www.amazon.com/CSI-Miami-Jeff-Mariotte/dp/1932382542/ref=sr_1_1?ie=UTF8&s=books&qid=1238777890&sr=8-1 It's already happened.]]

[[WMG:Brass is a reptilian shapeshifter.]]
The woman from the Lizard Cult was ''not'' hallucinating that snake-tongue. There really is a conspiracy of alien reptiles in the [=CSIverse=].

It explains the more advanced technology.

The reason [=CSIs=] do so much multitasking fieldwork, interviews, and interrogations is that the Las Vegas lab is a training/recruiting center for TheMenInBlack that cover up this secret. Grissom leaves the lab because he's been recruited. Ecklie's in on the secret; his usual actions are Obfuscating Dickery.

[[WMG: CSI takes place in the same universe as Series/CriminalMinds]]
Because it would be awesome to see Horatio Caine or Ecklie be the victim of a Hotchalanche.
* With the appearance of Angela's dad on ''Miami'', it's also part of the ''Series/{{Bones}}'' universe.

[[WMG: Nick killed the babysitter that raped him when he was a little kid]]
Nick has only mentioned that he was raped once, to Catherine in the second season. This makes sense because it was a traumatic experience; there was no need to bring it up for some seasons after.

Many years later, in an episode called "Death and the Maiden," a boy was raped. Even though Nick took the lead in the case, he never mentioned that he was raped, even though it would have been beneficial to do so at several points. But he did say, "If I were Tommy, I'd of killed him too."

He ''was'' in a similar position to Tommy once. Therefore, Nick did kill that babysitter. He did not bring up the rape during this case because he was afraid people would finish the parallel.

[[WMG: The Next Season of CSI will end with...]]
Catherine and Vartann's marriage. Because we deserve a little happiness, dammit!
* Er, nope...we're pretty sure of that even though her end hasn't aired yet.
* Was it a coincidence that Catherine almost started a relationship with FBI Agent McQuade in “Zippered”, and then at the end of that same season resigned so she could join the FBI, I think not.
* Alternately, Nick will return to the lab as a supervisor post-series and he and Cathererine will declare their love finally.

[[WMG:Viewers aren't morons ... but [=CSIs=] are.]]
Why is it relatively easy for us to figure out who the killer is before the [=CSIs=] do? We're supposed to.

The [=CSIs=] are so dependent on where the evidence takes them that they miss the things that the viewers are ''meant'' to catch.

[[WMG: There will be another spinoff to cover another area of the country, [[RecycledInSpace again.]]]]
There are is one team in the west (Vegas), southern coast (Miami), and the Northeast (NYC). Other possibilities:
# Los Angeles. It's where all the cool large procedural agencies have branches. ''Series/{{NCIS}}'' is there, ''Series/LALaw'' was there, ''Series/LawAndOrderLA'' was there -- even Series/{{Columbo}} was there. But that might be a bit close to Las Vegas...
# Washington, DC. A coastal city, perhaps a little close to NYC, but it would be fun. Or maybe Baltimore -- that is another popular place for procedurals.
# Indianapolis...
# Rochester, Minnesota.
# Rochester, New York. If Los Angeles would work, so would this.
# Chicago. Lots of shows there, but few criminal procedurals, and we want something more uplifting than ''Series/TheChicagoCode.''
# Dallas. One in Texas would make a nice genre change -- dragging police work into the 22nd century...
# Louisville, Kentucky. Much bigger and darker than it looks on Derby Day. May have some of the benefits of Dallas.
# Detroit!
* Or maybe another country? ''Franchise/LawAndOrder'' has a UK version, so why not CSI too? Or would Creator/TheBBC sue them for copying Series/WakingTheDead?

[[WMG: The gorilla in "Evaluation Day" came from the same zoo as the grizzly in "Unbearable"]]
And was also the victim of a "canned hunt". Why else would some furtive kill and skin a gorilla ''in Vegas''?

[[WMG:Thumpy G (Revenge is Best Served Cold) was actually Det.Danny Messer from NY's crime lab, taking part in an undercover mission. He just didn't say it to the [=CSIs=] so as not to break his cover to anyone else around them.]]

[[WMG: D.B's wife will be played by Shelley Long]]
At the moment it looks like his wife is TheGhost, just mentioned a lot but not seen. However it seems like since D.B is well known to audiences as Sam from Cheers then it wouldn't be much of a suprise to have the one who played Diane on that show. This is based on genre-saviness because TvTropesWillRuinYourLife.

Close. It's actually Roz from ''Series/{{Frasier}}''.

[[WMG: Grissom is [[Film/ToLiveAndDieInLA Richard Chance]], back from the dead.]]

[[WMG: This show came to an end when the events of ''Series/{{Revolution}}'' occurred.]]
It's difficult to keep a TV series going, when a worldwide blackout renders television useless.

[[WMG: Warrick's son will become a CSI when he grows up.]]
* With Lindsey a CSI also, it can be a next gen sequel series.
