(with a zero) is a re-imagining
of the 1968-1980 series Hawaii Five-O
(with an O) that started airing in Fall 2010.
It stars Alex O'Loughlin (Steve McGarrett), Scott Caan (Danny Williams), Grace Park (Kono Kalakaua), Daniel Dae Kim
(Chin Ho Kelly), Jean Smart (Governor Pat Jameson) and Masi Oka (Max Bergman). In the new setting, McGarrett is a Navy SEAL whose father is murdered by an international terrorist he had been tracking, triggering the formation of what becomes the Five-0 unit, a special police force that operates above the normal state jurisdictions.
Put character tropes in the Character Tab
, please. A recap page
is also available.
Hawaii Five-0 provides examples of the following tropes:
- Action Mom: Doris McGarrett seems to have been one of these, and still is even though her son's grown up.
- Affably Evil: Danny's brother, Matt. He is a money launderer, Wall Street fraud, and lifesavings thief, but he knows how to have fun.
- All for Nothing: In season 2, Jenna sells out Steve to Wo Fat for her already dead fiancé and Wo Fat kills her afterward. Quite a Genre Blindness, indeed.
- American Accents:
- Hawaii's pidgin English (officially "Hawaii Creole English") features in most episodes, as spoken by various minor characters. McGarrett, Kono, and Chin Ho all understand and can also speak it — to the confusion of Danno, the only member of the Five-0 team not born and reared in Hawaii. Even when not speaking purely in Pidgin, McGarrett, Kono, and Chin Ho often use da Pidgin kine expressions and phrases, brah.
Surfer: Ho, brah, where you eat it?
Danno: I'm sorry, what?
Surfer: Da kine, brah.
Danno: I'm sorry, are you speaking English?
Surfer: Hey no need for get agro.
McGarrett: He caught it on land, brah... Danno don't surf.
Danno: I dare you to tell me what he just said.
- Danno has a very strong Joisey accent, which is pretty accurate for the region he claims to be from.
- Steve's Tough Guy accent shades into some kind of New York/Joisey hybrid sometimes, even though he's from Hawaii. Maybe his Australian actor imprinted on Scott Caan?
- SWO2 Graham Wilson, the SEAL with PTSD in "Ho'apono."
- The bad guy in "Loa Aloha" is quite sympathetic at the end.
- Artistic License – Geography:
- For a show filmed mostly on location in Hawaii, there is a lot of artistic license, ranging from how they travel or respond to a location, to the naming of locations.
- At the end of Danny's flashbacks to 9/11 in "I Ka Wa Mamua" during the third season, he sees police cars and ambulances racing past him to the burning Twin Towers. Yet the episode suggested that he and his late partner had learned that the drug deal was going down in Manhattan near the George Washington Bridge (and they're even shown crossing it to get there). That's way too far uptown for the towers to have been that close.
- Artistic License – Gun Safety: To get the police out of the vehicle carrying the arrested robbers so they can get Catherine released in the fourth-season premiere "Aloha kekahi i kekahi", Steve fires into the air twice, something a Navy SEAL should surely know is dangerous and reckless regardless of the situation.
- Ascended Extra: Lt. Catherine Rollins, McGarrett's on-and-off active-service Navy girlfriend who largely just serves to provide Five-0 with the lead to advance the case in the first season, becomes a full member of the regular cast in Season 3.
- Astronomic Zoom: Used at the start of "E Malama".
- A-Team Firing: You've got Danno, armed with an assault rifle, and Wo Fat, armed with a sniper rifle, firing at each other, with not even ten yards separating them. No one hits anyone.
- Bait-and-Switch Gunshot:
- Subverted in "Kanalua". McGarrett and Danny have their guns drawn on the wounded survivor of the robbery at the beginning of the episode, who's got a hostage at gunpoint. All of a sudden, he falls to the ground, not from a gunshot anywhere but because he had died from his earlier wound. The subversion is lampshaded throughout that and the next scene, when Danny refuses to believe that McGarrett didn't actually do something, or even that he just knew the Mook would choose that exact moment to succumb.
- Played straight at the end of "Malam Ka Aina" when Chin saves his cousin Sid.
- And again when Danny saves Steve at the end of "Huaka'i Kula".
- Bat Scare: After the Cat Scare in "Mohai", Danno gets his own scare in an allegedly haunted house form a flock of birds.
- Batter Up: Rollins carries one when she and McGarrett hear an intruder in the house at the beginning of "Propilikia". It turns out to be his mother.
- Beauty Is Never Tarnished: Averted consistently: if anyone gets hit in the face, expect to see bruises. After a long and violent fight which involves destroying about half a house and getting captured and slapped around, Kono shows the damage.
- Berserk Button:
- Don't mess with Danno's friends. And do NOT come between him and his daughter. Danny also reveals that as a result of Grace's kidnapping, his tolerance for anyone who dares abduct a child enrages him to a level that his "interrogation technique" makes McGarrett queasy.
- Do not hurt, threaten, or breathe wrong near McGarrett's family. Children who lose a parent also seem to be a trigger for him ("He Kane Hewa' Ole").
- Family for Chin Ho and Kono.
- And in a way, Wo Fat; never ever try to investigate him.
- Big Damn Heroes: In the pilot, McGarret and Chin Ho save Kono from some gangsters by driving a truck through a wall.
- The Navy SEALs in "Makani 'olu holo malie" as they storm a Taliban compound to save Steve before he can executed live on camera.
- Big "NO!": McGarrett yells one when Victor Hess shoots his father.
- Big Screwed-Up Family: After 100 episodes, it is revealed that Steve McGarrett happens to be a part of one. His mother, Doris McGarrett a.k.a. Shelburne, was tasked with eliminating an unknown Chinese man, but she bungles the mission and kills his wife. Out of guilt, she becomes the stepmother to that man's son, Wo Fat. However, she is pulled away by the United States, and Wo Fat's father disappears, leaving Wo Fat to believe he was murdered, which was his Start of Darkness. This makes Wo Fat McGarrett's stepbrother. His mother abandons Steve's family for her spy work, John McGarrett gets involved with Wo Fat and is eventually killed on his orders, starting his blood feud with Steve, and, after returning to Hawaii, Doris kept in touch with Wo Fat without Steve's knowledge, keeping this secret.
- Bilingual Bonus:
- All episode titles except the pilot and season three's "Hookman" are in Hawaiian.
- The name of Hiro Noshimuri (a season one villain), while not an actual Japanese name, is made of Japanese words; "Noshi" is a type of origami tied to ceremonial envelopes, "Muri" means impossible." Judging from the Google hits, the writers ate him at a restaurant.
- In "I Helu Pu", we learn that Danny knows a few Russian phrases, including "I'm a police officer" and "Your vodka tastes like urine."
- Buddy Cop Show: Playing this trope incredibly straight with Steve and Danny, even though they are not the only main characters on the show.
- Bulletproof Vest: The team is VERY consistent about putting these on when shooting is likely.
- Busman's Holiday: Danno and Steve cannot take a mere hike through the jungle without stumbling upon a corpse, or having to save the kids trekking with them from being taken hostage by smugglers.
- Butt Monkey: Danny's Nephew, Eric, played by Andrew Lawrence (of the Lawrence brothers fame), in the "Kapu" episode.
- By-the-Book Cop: Danno tries to be this but it's tough when the Cowboy Cop is the boss and has been given license by the governer to basically do whatever the hell he wants.
- Cain and Abel: Danny, a straight cop, is the Abel; his brother, Matt, is a Wall Street fraudster, savings thief, and drug money launderer.
- In a stepbrother example, Steve is revealed in the 100th episode to be the Abel to Big Bad Wo Fat's Cain.
- California Doubling: Well, Hawaii Doubling — with the exception of the aerial footage over Osaka, the scenes in "Ua Hapa" where Steve looks for Wo Fat in Japan were actually filmed in downtown Honolulu. You could even see the Top of Waikiki through Wo Fat's hotel window.
- Averted in Season 4 when Kono was searching for Adam, eventually finding him in Vancouver. Grace Park had small parts in (or outright missed) several episodes due to her maternity leave, but filmed a few scenes in her hometown of Vancouver before returning to Hawaii to resume her role full-time.
- The Caper: "Heihei"
- Captain Smooth and Sergeant Rough: Inverted with Steve and Danny. Lampshaded frequently by Danny when he rants at Steve about the rules of civilised society and how normal people behave.
- Catch Phrase: "Book 'em, Danno."
- Cat Scare: In the Halloween Episode "Mohai", the Five-0 team searches a dark alley for clues about a missing woman when Kono discovers something moving inside a garbage container. When she carefully opens it, a black cat hisses at her and jumps out of the bin, scaring her to death.
- Characer Death:
- The Governor in the first-season finale.
- Jenna Kaye in "Ki'ilua", midway through the second season.
- Vince Fryer in "Ua Hala", the second season finale.
- Malia Waincroft, Chin Ho's wife, in "La O Na Makuahine", the third-season premiere
- Danno's brother, who was killed off-screen by a money launderer.
- Wo Fat in the series' 100th episode, "Ina Paha", with a gunshot wound to the head from McGarrett.
- ...Annoying Granny: The talkative granny that saw Kono and Steve's break-in to the HPD evidence locker in "Hana'a'a Makehewa" shows up as the one picking Kono out of a lineup in the Season 1 finale, "Oia'i'o."
- ...Cell Phone: In "Lanakila", Mary photographs all contents of the Champ box. In "Ke Kinohi", the bad guys have stolen the actual contents, so Five-0 relies on her pictures to continue the investigation.
- ...Gunman: Wo Fat, the Big Bad, is first seen as a golfing partner of the villain they're investigating midway through the first season.
- ...Gunshot Wound: In "Ho'opa'i", two agents on an FBI security detail are shot during a mob raid on an undercover agent's safehouse. One agent survives, but the other dies. Why? Because the ammunition used to shoot the survivor only contains half as much gunpowder as a normal round would have, making the wound it causes much more survivable. This reveals that the survivor is the mob's mole.
- ...Newspaper: In "Powa Maka Moana", a woman survives pirate attack in which all of her friends get taken hostage. Her dramatic reunion with her lover is photographed and appears on the front page of the newspaper. For her safety, Five-0 keeps her name secret. When the kidnapper calls Five-0, he demands that she deliver the money, but slips into calling her by her first name. It is later revealed that the woman and her lover are the bad guys.
- ...Inventory Control Documentation File: In "Ua Hiki Mai Kapalena Pau," it is revealed that the list of serial numbers for the $28 million in the HPD evidence locker, which everyone had thought was missing, was still intact. This allowed Chairman Akahoshi to determine that the $200,000 that Chin Ho "returned" actually wasn't the same money that went missing. However, that same list will also establish that $10 million of the $28 million isn't the same $10 million that was originally there — thereby exposing Five-0's unauthorized "borrowing" to ransom Chin Ho in "Hana'a'a Makehewa".
- The Chessmaster: Delano
- Child Prodigy:
- Grace and her fellow Aloha Girls in "Huaka'i Kula." Lucy is strikingly proficient in first aid, Grace digs an escape tunnel, and Sara MacGyvers a working cell phone out of the smashed-up remains of two different phones.
- See also the Little Miss Con Artist entry below.
- City of Adventure: There are an awful lot of high-profile murders, organize crime rackets, and attempted terrorist attacks in Hawaii; makes you wonder why anyone would want to vacation there...
- Fake Guest Star: Lauren German as Lori Weston in the early episodes of season 2. Eventually she was promoted to the opening credits... sort of.
- Fake-Out Make-Out: Danno and Kono in "Malma Ka Aina".
- Faking the Dead:
- Hiro Noshimuri, with Joe White's help. Becomes a minor Story Arc, as his son suspects Joe of murdering him and Steve has to prevent him from retaliating until he's able to convince Joe to tell the truth about what happened.
- Doris McGarrett, in the show's backstory, but only disclosed at the end of the second season.
- False Flag Operation:
- The dictator's private security detail in "Po'ipu" is actually a hit squad hired to assassinate him.
- The bad guy in "Kai'e'e" fakes a tsunami warning to fool the entire state of Hawaii.
- The "pirates" in "Powa Maka Moana".
- The mob hit in "Ho'opa'i" was part of an elaborate plot by the Big Bad mobster's son to frame his father for the murder of an FBI agent so he could take over Daddy's criminal empire.
- The use of sarin in the milk is to make cops believe that this is a terrorist attack, not simple crime of passion.
- Hello, Grace Park in a bikini.
- And in her underwear. (See Shameful Strip below.)
- And shirtless Alex O'Loughlin.
- And Daniel Dae Kim on a motorcycle.
- Double bonus: Shirtless Scott Caan getting surfing lessons from Grace Park on the beach in "Kai e'e".
- Ahem. Claire Van der Boom in "Loa Aloha".
- The "Swimsuit Edition" photo shoot/crime scene in "Ho'ohuli Na'au".
I'm going to talk to these models. McGarrett:
Okay, well just stay with the questions that relate to the case. Danno:
What's that supposed to mean? McGarrett:
That means I know you. Just stick to the case. Danno:
Hey. Hey. They're just women. Chin Ho: Who happen to be insanely hot and make millions of dollars.
- The "Victoria's Secret" subplot in "Ha'awe Make Loa", with Danno guarding supermodel Behati Prinsloo. A supermodel whose name is pronounced "Be-hottie". What are the odds?
- Danny as "Mr. November" in the New Jersey police calendar in "Kapu".
- Four words: girl-girl surfboard chase ("Kanalu Hope Loa"). And yes, one of the girls is Kono.
- Faux Fluency: In the pilot episode, McGarrett asks a young Chinese illegal immigrant her name, in Mandarin so badly pronounced as to be barely recognizable. McGarrett once again shows off his (not so) impressive Mandarin in "He Kane Hewa'ole". At some points it's somewhat acceptable for a non-native speaker, while at others it's hilariously bad.
- Fictional Counterpart: A few episodes reference the "King's Medical Center", instead of the real-life Queen's Medical Center.
- Fish out of Water: Danny Williams, formerly of New Jersey, who doesn't like Hawaii, or as he calls it:
Danno: ...this pineapple-infested hellhole.
McGarrett: You don't like the beach?
Danno: I don't like the beach.
McGarrett: Who doesn't like the beach?
Danno: I like cities, skyscrapers, no tsunamis, no jellyfish.
- Flower in Her Hair: Kono, for Chin Ho's marriage.
- Framed Face Opening
- From Bad to Worse: "Oia'i'o"
- Fun with Subtitles: Notice that in the first three episodes Five-0's headquarters is subtitled "Governor's Task Force headquarters" as the team hasn't come up with a name yet.
- Gender Flip:
- Kono is now Chin Ho's female cousin.
- Governor Paul Jameson is now Governor Patricia Jameson, probably because Hawaii's governor at the time of the pilot was also female.
- And the recurring character of Justice Department official Jonathan Kaye is now former CIA analyst Jenna Kaye. She turns out to be working with Wo Fat, but she performs a Heel-Face Turn before getting Character Death by Mr. Fat.
- Genre Savvy:
- Giant Wall of Watery Doom: Season 1 Episode Kai e'e. The Tsunami warning system is taken over and a false warning sent out. This is going to be used by the bad guys to facilitate their robbing the police headquarters.
- Good Cop/Bad Cop: Danny is good; Steve is bad. It goes the other way around when the case's about Danny's family, however.
- Gunpoint Banter: McGarrett and Wo Fat in "Ne Me'e Laua Na Paio":
- Halloween Episode: "Ka Iwi Kapu". Five-0 investigates the murders of two college kids out shooting video for a documentary on legendary Hawaiian ghost warriors in an ancient Hawaiian graveyard at midnight on Halloween.
- Heterosexual Life-Partners: Steve and Danny, who are both absolutely ready to die for (or simply with) each other, and have recently reached the point where they can actually say "I love you" to each other in complete seriousness.
- Hitman with a Heart: One episode involves a hitman who takes out another hitman to protect a community in Hawaii made up of persons who the former was suppose to be assassinated.
- Hoist by His Own Petard: McGarrett and Danno catch a suspect putting a roofie into a girl's drink. They force him to drink it before carting him off. He passes out. They then awaken him with an air horn.
- Hollywood Healing: Considering how often these people get pounded like pieces of meat, they recover astonishingly quickly and without lasting damage.
- Horrible Camping Trip: "Huaka'i Kula"
- I Call Her "Vera": Sam Hanna dubs Danno's Camaro "Winifred". "Winnie" for short.
- I Can See You: At 1:20. "Should have taken the deal. By the way, that's a nasty cut on your eye."
- Identical-Looking Asians: Inverted, Pacific Island natives are usually grouped with Asian ethnicities, there are several times where suspects can't give a description of someone they met past "he was a haole".
- Idiosyncratic Episode Naming: All the episode titles (except for the pilot episode and the season 3 episode "Hookman") are Hawaiian words or phrases. (The pilot episode is named "Pilot", and "Hookman" is a remake of the 1973 episode from the original series with the same name.)
- I Need a Freaking Drink: The Governor, after McGarrett informs her that a very high-profile philanthropist and campaign donor is actually the head of the Yakuza in Hawaii. She doesn't play around either. When McGarrett starts to look for a glass for the beer, she quickly corrects his train of thought and starts drinking straight from the bottle.
- Internal Affairs:
- Sgt. Cage ("Mana'o"), who drove Chin Ho off the force and investigated Danny's partner post-mortem.
- Chairman David Akahoshi in Chin Ho's Story Arc ("Ho'ohuli Na'au", "Ua Hiki Mai Kapalena Pau", and "Oia'i'o").
- Pauline in "Ho'ohuli Na'au" goes to great lengths to murder her father because he abandoned her and her mother, only to be told by Danno, as he arrested her, that her father had established a trust for her benefit and was planning to reconnect and make up for it. Even more ironic in that because she murdered the grantor of the trust, she forfeited her rights as a beneficiary.
- The Governor, whom Jack McGarrett has been investigating, authorizes the creation of Five-0 so she can keep an eye on Steve who subsequently takes up his father's investigation. We see how that finally works out in the Season 1 finale, "Oia'i'o".
- It's Personal:
- McGarrett in the Story Arc concerning the murders of his parents ("Pilot", "Hana 'a'a Makehewa", "Ke Kinohi", "Ne Me'e Laua Na Paio", "Ua Hiki Mai Kapalena Pau", "Oia'i'o", "Ina Paha").
- Danno in "Mana'o", "E Malama", and "Loa Aloha".
- Kono in "Ko'olauloa".
- Jenna Kaye feels this way about Wo Fat.
- The entire team in "Hana 'a'a Makehawa", when Hesse rigs the bomb to Chin.
- And again in "Ki'iluna" when Wo Fat kidnaps McGarrett. Mr. Fat kidnaps McGarrett a second time in "Ina Paha", where a lot of questions are answered.
- Kansas City Shuffle: Delano pulls an epic ton of 24-style misdirections in Season 2 finale and Season 3 premiere. In "Ua Hala", he ordered a pissed-off ex-con to kill an HPD friend of Five-0's. When the police cordons the crime scene, the ex-con slips in a police car, sneaks her way to the HPD HQ, and sets off an explosion there. The ex-con's background leads the Five-0 to believe that the explosion is motivated by revenge, and indeed at the end of the episode it is revealed that Delano holds both Malia and Kono hostage and forces Chin to save them. In "La O Na Makuahine", his real endgame is revealed: 35 million dollars worth of drugs stored in HPD evidence room, which he could access by posing as a cleaner crew, which the HPD calls to clean their HPD after the explosion.
- Karma Houdini: According to a CIA analyst, Wo Fat is this. Subverted as of the series's 100th episode. After being arrested twice, and escaping prison twice, Wo Fat finally is shot and killed by McGarrett. Karma has finally caught up to him.
- Lampshade Hanging
- McGarrett describes the series' most famous phrase ("Book 'em, Danno.") as "catchy" when pressed by Danno himself.
- In this series, as the odd haole (non local) out, he is the king of the Lampshade Hanging, especially when it comes to McGarrett's ridiculously illegal interrogation techniques.
- Laser-Guided Karma: Danno in "Ka Iwi Kapu." He enters sacred ground without getting "cleared" first and being disrespectful to the site and his superstitious co-workers; a rock is thrown into the window of his Camaro as a result. TWICE. It gets even more worse though. Tipped off by an old lady in front with a dog (who politely informs him the elevator isn't working), Danno convinces the property manager to rent out one of the victims apartment to him reasoning that a crime scene would be a deterrent to would be renters (since the manager would have to disclose this fact to would be renters) and he is ready to go in and isn't afraid of the past history. On moving day, Danno talks to the property manager about putting in a pet deposit due to Grace wanting a pet. The manager informs Danno there is a no pets allowed policy. When Danno mentions the old lady out in front with the dog, the property manager informs Danno that he is describing an old tenant who died when she fell into the elevator shaft of said building several years ago. Cue Danno making a hasty retreat out of the apartment much to the disgust of his co-workers who helped him move in and fix up the apartment.
- Like an Old Married Couple: McGarrett and Danno.
- Lampshaded in "Lanakila":
Convict: Hey, how long you two been married?
- and "Ua Lawe Wale":
Lori: How long have you two been married?
- and "Lekio":
Tony: I'm gonna be your marriage counselor!
- and by Danny himself in "Kanalua":
Danno: Let's just say that, over the years, our marriage has become predictable.
- and by Joe White in "Kupu'eu", complete with a name-drop.
- Little Miss Con Artist: In "Kai 'e'e", Grace dominates Kamekona and his friends at the poker table. They're only playing for candy, though.
- Look Both Ways: A former-CIA assassin is killed by a bus after a lengthy firefight in a crowded street where nobody hits anything.
- Lost at Sea: "Lana I Ka Moana" (whose title is Hawaiian for "Adrift") partially employs this trope when it starts with Danny and McGarrett getting their boat hijacked on a fishing trip, far enough offshore that it's no longer visible. The thief leaves them in the dinghy they found him in, which no longer has a working motor, and although it seems eminently possible they can save themselves (and eventually they do), at first Danny sees their situation as hopeless.
- McGarrett regularly improvises fingerprint powder from ordinary household substances.
- In "E Malama", we get an improvised flamethrower made with hair spray and McGarrett's field-expedient booby trap.
- In "Ma Ke Kahakai", McGarrett makes his own splint after breaking his arm.
- The Man Behind the Man: Wo Fat. He's the man behind:
- Victor Hesse (revealed at the end of "Hana'a'a Makehewa")
- Noshimuri and the Yakuza (implied strongly in "Ke Kinohi," confirmed in "Ne Me'e Laua Na Paio")
- Sang Min ("Ua Hiki Mai Kapalena Pau")
- and even the Governor!! ("Oia'i'o")
- Don't be shocked if he also has something to do with Danny's brother the money launderer.
- According to Jenna Kaye, criminals don't work with Wo Fat, they work FOR him. Also she worked for him.
- Mistaken for Gay: In "Kapu" Steve and Danny visit a sorority house, and one of the girls mistakes them for her friend's parents.
Girl: Kelly, your dads are here to pick you up.
- Mister Muffykins: In an episode, a ruthless Dragon Lady and slave ring owner they'd caught refuses to give any help to Five-0 in their current investigation... until Kono threatens to have her Pomeranian euthanasied.
- Mixed Metaphor: Danno, when he gets worked up, creates some entertaining mash-ups of figurative language.
I am really happy you are not afraid of anything, okay? I'm glad you have that G.I. Joe
thousand-yard stare from chasing shoe bombers around the world, okay? But in civilized society, we have rules, all right? It is the unspoken glue that separates us from jackals and hyenas, all right?
- More Deadly Than The Male:
- Hillary Chaver, the villain in "Ha Uala". She sets a trap to take out Vince Fryer, gets shot by him as he dies, yet still hangs around long enough at the scene to shoot Max when he follows her blood trail, then steals a police car and leads the chasing McGarrett and Danno right to... HPD headquarters, knowing that it will prove difficult to distinguish her stolen cop car from all the other ones parked there. Then... she fools McGarrett in the hallway to buy time, manages to set up a gas explosion that injures about 20 cops as they try to flee the building, and goes to a nearby veterinary clinic where she kills the receptionist in cold blood, then, after getting the surgeon on duty to patch her up, kills him as well, and then engages in a final, fatal gunfight with the Five-0 team.
- Dr. Olivia Victor, the psychopath psychiatrist in "Wahine'inoloa". She killed the victim from the Cold Open by shooting him nonfatally, then pouring gasoline all over him and dumping him into a burning sugar cane field. McGarrett sees through her, but can't convince the others, and his attention wind up with her getting a restraining order against him, which she then manipulates him into violating. She kills two more people before getting caught at the end of the episode.
- Mr. Fanservice: The boys of the Five-0 team. In-Universe, too: Kensi Blye apparently got a little hot and bothered when Danno and Chin Ho showed up in L.A. in part two of the big crossover.
- Ms. Fanservice: Kono, as if you hadn't already guessed.
- The Mole: In the first episode, a Hawaiian gangster has one of these in the Honolulu PD; after forcing an undercover Kono to undress to her bra and panties, he takes a picture and sends it to the mole to make sure she's not a cop.
- Mood Whiplash: "Ina Paha" alternates between Wo Fat's brutal and Cold-Blooded Torture of McGarrett—using mind-altering drugs, electrodes, and good old fashioned physical brutality—and McGarrett's drug-induced hallucinations of a Lighter and Softer alternate universe version of the pilot episode where Victor Hess is stopped from killing John McGarrett at the last second, Chin Ho is still on the force,, Danny is a happily-married Cowboy Cop who loves living in Hawaii, Kamekona is an imprisoned crime lord, and Kono is a four-time world surfing champion doing TV commercials for lip gloss. Though Jerry is crazy and homeless in this alternate universe.
- Mugging the Monster: An episode starts off with McGarret picnicking with his girlfriend in his car... and a mugger shows up, trying to carjack them at gunpoint. Smash Cut to an annoyed McGarret dragging the scum to the police station — after ripping off his nose ring. The sergeant welcoming them finds this very funny, and comments to the perp that he picked the wrong guy.
- My God, What Have I Done?: Said almost word by word from a victim's parent during one episode. In the episode, college students partying on a boat are captured by pirates. When the Hawaii Five-0 team informs the parents that negotiating with the pirates' demands is a surefire way to get their children killed, one kid's father doesn't listen and secretly gives the pirates 400K to spare his son, despite his wife's reluctance to disobey the Five-0 team. When the pirate group's leader got impatient with the Five-0 team not complying with the ransom demands, he kills a kid and dumps him onto the beach. Guess who's the slain kid? The other students? They eventually get rescued, and were unharmed.
- Myth Arc: Five-0 vs. Wo Fat, and the related mystery of John McGarrett's past.
- Mythology Gag:
- The opening titles are clearly an homage to the 1968 original. This even includes the zoom in from the sky on each version's McGarrett at the beginning. No points for using a sped-up homage of the first season ending credits with the police bike blue light.
- The beachfront cookout/make-out scene between Steve and Catherine at the end of "Nalowale" seems to be an homage to the beachfront cookout in the original series' pilot film "Coocoon".
- The big black '74 Mercury Marquis sedan McGarrett senior had in his garage is one of the cars Jack Lord drove in the original series. (See this article under "The Ride", and this one in a car blog.) Steve decides to finish restoring it, and this was a minor Story Arc ("He Kane Hewa'ole", "Powa Maka Moana"). By the end of the first season, in "Oia'i'o," Steve has finished the restoration and the Mercury may even be his daily driver. (He drives it to Kamekona's place to obtain a gun for use in his Roaring Rampage of Revenge.)
- Al Harrington, who appeared in six different roles in the 1968-80 original (including as Five-0 member Ben), plays an elderly surfer first seen in "Ke Kinohi". The role was originally intended for James MacArthur, who played Danny in the 1968 series, but he died unexpectedly before the episode was filmed.
- Dennis Chun, the son of Kam Fong (the original Chin Ho), has a recurring role as Sergeant Duke Lukela of the HPD, a character from the original series.
- In "Palekaiko", Danny quips that people wear ties on cruise ships "so they can hang themselves when they get bored." This is a reference to the title of the original series' Missing Episode, "Bored, She Hung Herself".
- Helen Kuoha-Turco, the hula dancer from the original show's opening credits, had a small role in "Malama Ka Aina".
- More of a Mythology Carryover, but many viewers may not know, or have forgotten, that the original Steve McGarrett was also ex-Navy, albeit not a SEAL.
- The season two finale "Ua Hala" translates to "A Death in the Family", the same name as the original show's season 11 finale in which Chin Ho faces Character Death. Interestingly, the situation this sets up also results in tragedy for Chin Ho's family, although this time it's his wife who gets it.
- "Kai'e'e" tsunami plot is almost similar to two old Hawaii Five-O episodes: "Forty Feet High and It Kills!" (Wo Fat engineers a tsunami warning to kidnap a geneticist) and "Tsunami" (several geology students engineer a tsunami warning by holding the head of the Pacific Tsunami Warning Center hostage while they rob a jewelry store posing as rescue workers).
- In the original series, the governor was played by Richard Denning. In the new series, Governor Jameson is replaced after the first season by Governor Sam Denning.
- "Hookman," a remake of/homage to the original series episode of the same name.
- Edward Asner reprised his role of smuggler August March from the original series' "Wooden Model Of A Rat" in season two's "Kalele."
- Naked People Trapped Outside: In the third-season "Ha'awe Make Loa", Five-0 comes upon a suspect they'd like to talk to dancing in his yard wearing nothing but a hula skirt. As he flees, the skirt gets stuck on the fence, and he winds up streaking a busy street in his vain attempt to flee.
- Never Bring a Knife to a Gun Fight: In "Kekoa", McGarrett shoots a suspect, swinging a knife on a thong and approaching, in the leg.
- Never Trust a Trailer:
- The trailer of "Ke Kinohi" makes a big deal of the stolen Champ box and the kidnapping of Steve's sister. Five-0 managed to recover the box, and despite all of its contents being removed by the bad guys, it turns out that Steve's sister has photographed them for backup. And the kidnapping is solved within the first fifteen minutes of the episode.
- The trailer of "Kai e'e" cut the episode footage together to make it seem like a tsunami really was going to crash down on Hawaii. In actuality, the tsunami was being faked by the criminals — something of a Call Back to the original series, as a fake tsunami scheme was also used in "Forty Feet High, And It Kills!" — and the scene of a wall collapsing inward was a Big Damn Heroes moment involving a forklift.
- The Nicknamer: Tony Archer in "Lekio" gives plenty silly nicknames to McGarret and Danno.
- Noodle Incident:
- Not Quite Dead:
- McGarrett's mother, also known as "Shelburne".
- The hitman she thought she had killed twenty years earlier in "Wahine'inoloa"
- Not What It Looks Like: Lori and Danno being found handcuffed.
- Obstructive Bureaucrat: Averted with the first Governor to a point (Pat Jameson), and lampshaded heavily with the second one (Sam Denning).
- Oh, Crap:
- McGarrett has had several of these.
- The first is in the pilot, when he hears that his father has been taken hostage.
- The second occurs in "Ke Kinohi", when he sees the Yakuza boss complicit in his parents' death has a lunch date with the Governor.
- The third occurs in "Ne Me'e Laua Na Paio" during the meeting with Wo Fat:
- And then, in "Oia'i'o", when he discovers that the Governor is working for Wo Fat.
- The whole team has one in "Kai e' e" when they realize that the crooks who generated a fake tsunami warning to cover a robbery are trying to steal the $28 million of drug money in the HPD evidence locker from which the team "borrowed" $10 million to pay Chin Ho's ransom in "Hana'a'a Makehewa". If they try to stop the robbery they'll be exposed as having appropriated the $10 million that Hesse threw into the fire. Then they have another one at the end of the episode, when they learn that someone else put the $10 million back!
- The pirate/kidnappers in "Powa Maka Moana", when they see what's in the ransom bag is not 20 million bucks cash, but a bunch of yellow pages.
- Joe White in "Ka Hakaka Maikai". Realizing that there's an intruder in his house, he pulls out the gun he keeps hidden in the freezer for just such an emergency and points it at the intruder, Wo Fat, only to find Wo Fat's already found it and taken the bullets out of the gun.
- In "Ki'iluna" after being captured by Wo Fat, Steve attempts to engage him in their customary witty banter and is completely ignored. You can see on his face the moment he realizes that Wo Fat no longer regards him as a Worthy Opponent and he's pretty much screwed.
- Odd Couple: Danny and Steve are this trope.
- Oddly Small Organization: Five-0, a state police agency, is a group of eight detectives at max. Justified in both this and the original as in real life, Hawaii is the only state that doesn't have a state police.
- Older Than They Look: Apparently, Grace Park is 37 years old. She looks about ten years younger.
- This gets especially weird when she plays Kono as a teenager in one of Chin Ho's flashbacks.
- Only Sane Man: Danny, as a regular cop, is Five-0's voice of reason. In-universe, Danny sees himself as this to the entire population of Hawaii.
- Origin Story:
- In the 1968 original, the team was called "Five-O" from the very start, with no in-show explanation of how the name came about. The re-imagined version provides one. At the end of "Pilot", the characters are sitting around the office trying to come up with something better to call themselves than the prosaic "Governor's Task Force", but can't think of anything. Two episodes later, at the end of "Malama Ka Aina", Kono derives the nickname from McGarrett's high school football jersey number.
- "Pilot" also has an origin story of sorts for Danny's nickname "Danno".
- Pre-Mortem One-Liner:
McGarrett: There's something you should know about your brother.
Hesse: What about him?
McGarrett: He died the same way you did. (shoots Hesse)
- Season 1 finale, "Oia'i'o".
Wo Fat: Everything is under control. (shoots the Governor)
- "Ka Hakaka Maikai"
Wo Fat: Tell John McGarrett that his son will be along soon enough. (tries to kill Joe White)
- The Plan: Wo Fat pulls off a beauty in "Oia'i'o".
- President Evil:
- Averted in "Po'ipu". The Evil Overlord flying in to Hawaii for a state visit is actually doing a Heel-Face Turn and coming to testify against his regime before a human rights tribunal.
- The Governor. Seemingly averted for the entire first season until "Oia'i'o".
- Private Military Contractors: White Fire in "Ohuna".
- Product Placement: Where to begin...
- One of Hawaiian Airlines planes is prominently shown in the opening montage and the company's facilities and planes have been used in the show.
- Partially averted in the Five-0/NCIS: Los Angeles crossover episode, where a fictitious airline replaces Hawaiian for those episodes. Which is odd, given Hawaiian does go to LAX among other California destinations.
- Early on in the first season numerous characters — notably McGarrett — own and prominently use iPhones. In one episode a father and son are seen talking to each other via FaceTime, a scene which eerily looks like an Apple commercial. Kono is also seen with a MacBook Pro numerous times. What makes this interesting is that after many episodes with extensive Apple product placements, in "Mana'o" Chin asks Kono to "Bing it", when she doubts his knowledge about a modern artist. Sure enough, Kono whips out her LG Optimus 7 and we get a close up of the phone's screen for almost 10 seconds. Soon after this episode Danny gets a new Windows Phone 7, and the Apple logos on both Kono's laptop and McGarrett's iPhone are suspiciously covered up.
- In the third season the characters are also making conspicuous use of their Surface tablets.
- Steve, Danny, and Kono drive brand new Chevy products.
- Various Hawaii businesses have had their names and products appear on the show, including Liliha Bakery, Kona Brewing Company, Waiola Shave Ice, and others. Most episodes will give at least one local company national advertising.
- For a group of locals they spend an awful lot of time at the Tropics Bar of the Hilton Hawaiian Village.
- The amount of Scenery Porn amounts to Product Placement for Hawaii itself as a tourist destination.
- Lampshaded, smacked up against the Fourth Wall, and played for laughs when Kamekona is seen eating Subway footlong subs in "Pu'olo".
- "Ha'awe Make Loa," in the third season, makes sure to regularly show us the Victoria's Secret logo along with its Fanservice models lounging on the beach.
- Mocked again in the fifth season opener, Aʻohe Kahi e Peʻe Ai, with a scene where Jerry "demonstrates" the automatic sliding door feature of his old minivan to Steve and Danny. Steve notes that the feature is very '90s.
- Professional Killer: "Po'ipu," "E Malama".
- Promotion to Opening Titles:
- Masi Oka in season 2 and Michelle Borth in season 3.
- Lauren German was sandwiched in between this and Fake Guest Star for most of her run as a series regular, shown as "Also Starring" in the first scene-post credits, before the actual guest stars were listed.
- Jorge Garcia and Chi McBride in season 5. McBride got "Also Starring" treatment midway through season 4.
- Psycho Psychologist: Dr. Olivia Victor in "Wahine'inoloa".
- Put on a Bus:
- Catherine Rollins, in "Mea Makamae"; she's been assigned to a tour of duty in the Persian Gulf. It doesn't stick. "I Helu Pu" finds Rollins on McGarrett's arm during the Governor's party. And then McGarrett does his reserve drill on the Enterprise.
- The bus was busy in "I Helu Pu". Lori Weston gets put on after resigning from the Task Force and going back to DHS.
- Catherine again near the end of Season 4, vanishing into the wilds of Afghanistan in search of an old friend held captive there. This came after she spent two seasons as a main character.
- Quip to Black:
- Race Lift:
- Type III in the case of Dr. Bergman, white on the original show and Asian-American (and with an actual first name) here.
- And Capt. Lou Grover, also white on the original show but black here.
- Real Life Writes the Plot:
- Scott Caan injured his knee in Season 1, leading them to writing in a knee injury for Danny.
- Alex O'Loughlin had problems with addiction to pain meds. For the episodes filmed while he was in treatment, McGarrett was said to be away from the islands tracking down Joe White.
- Reality Ensues: In the aftermath of Steve's rescue in North Korea, Joe White has to face the Navy inquiry hearing. At the end of said hearing, he is forced into early retirement.
- Red Shirt: If you're a Law Enforcement Officer in Hawaii, there is a slight possibility you might die when you're around any of the main cast or the prominent supporting cast.
- Refuge in Audacity:
- A psycho serial killer holds his hostage at knifepoint just inches away from a cliff. Danny tries to negotiate with him and Hilarity Ensues:
McGarrett: What are you doing? The guy is clearly a psychopath. You're trying to make friends with him. You're trying to connect?
Danno: He's standing right in front of us! He can hear you.
McGarrett: I see he's standing right here, Danny. But you're a cop. You're not a therapist, you know?
Danno: Hey hey hey! I've been trained for this kind of thing, okay?
McGarrett: What — what to bore people into submission?
Danno: Don't listen to him, okay. His idea of communication is — is he drops a witty one-liner and then shoots you in the face. Don't worry about it!
McGarrett: You know what — I might shoot this guy just so he doesn't have to listen to you talk.
(when the killer gets distracted by the debate and lowers the knife, Steve shoots him)
- As a whole, the "immunity and means" given to Five-0 are taken to ridiculous levels. Chin, Kono, and Danny are known to be a little "loose cannon" when the situation calls for it (the odd Jack Bauer Interrogation Technique occasionally crops up) but Steve definitely takes the cake.
- The Remake: Season three's "Hookman" is a remake of the same-named episode of the original show (and also the first post-pilot episode of the revival to have a title in English rather than Hawaiian).
- Retirony: In The Teaser of "E Malama", we find ourselves at an FBI safehouse, where a witness and a federal marshal are. The witness thanks the agent for his dedication to the job, including spending so much time away from his family. He says it's no problem. He's dead a few minutes later.
- Revealing Coverup: Chin barters his house's deed for 200k cash, which he hopes can obstruct HPD investigation to his uncle's embezzlement, believing that the storage records have been lost. It turns out that HPD have serial numbers on the money stolen, and they ascertain that Chin's money isn't the drug money.
- Rewarded as a Traitor Deserves: The Governor and Jena Kaye, both by Wo Fat.
- Ripped from the Headlines: The plot of the episode "Kupale" is based partly on the real-life drama of the Hawaii Superferry.
- Roaring Rampage of Revenge:
- The bad guys in "Lanakila" and "Loa Aloha".
- McGarrett is on the verge of one in "Ke Kanohi", but Danno talks him out of it.
- Danny is on one in "E Malama", and Steve can't talk him out of it.
- An undercover FBI agent appears to go on one of these in "Ho'opa'i".
- McGarrett goes on one in "Oia'i'o", confronting the Governor at gunpoint.
- Room Full of Crazy: Where McGarrett's mother and her pals are planning the caper in "He Welo 'Oihana".
- Ruthless Modern Pirates: The first season episode "Powa Maka Moana" dealt with a Spring Break Cruise being attacked and the kids kidnapped.
- Scenery Porn: Yes, Hawaii is beautiful, but the way the show portrays it, it's like paradise on Earth.
- Screw the Rules, I Have Money!: The Yakuza boss in "Ke Kinohi" is the state's primary benefactor. Averted in a sense, because while Steve cannot prove his involvement in his parents' death, he manages to arrest the boss for breaking in to his house, kidnapping his sister, and stealing the Champ box.
- Screw the Rules, I'm Doing What's Right:
- The whole point of the new unit.
Governor Jameson: ...Your task force will have blanket authority to go after guys like Hesse, and get them the HELL off my island. Your rules, my backing, no red tape....
- And this is being deconstructed slightly in season 2, as the fallout from the season 1 finale is coming back to haunt Five-0. The new Governor is keeping them on a much tighter leash, assigning them a team member of his choosing to keep an eye on them. And it turns out that Captain Fryer used a full police investigation of Five-0's behavior as leverage to get Kono to work for him.
- Deconstructed more in the season 3 opening episode, where Steve is on the phone with the Governor trying to explain and justify the actions of Chin-Ho's custody of Delano and his absconding at the season 2 finale plus Wo-Fats escape orchestrated by Delano earlier in the episode. Steve then tells Danno and Shelbourne riding in the car that the Governor is gonna open an inquiry into the whole fiasco over Chin-Ho's abuse of Five-0's immunity.
- Deconstructed even more in "O ka Pili'Ohana ka 'Oi" where the Governor orders Grover to leave the HPD permanently since his actions were not authorized and has wasted the police's resources in finding his kidnapped daughter.
- Sequel Episode: In "Kalele", Ed Asner reprises his role of art smuggler August March from the original series' 1975 episode "Wooden Model of a Rat". Doubles as Mythology Gag.
- Shameful Strip: A Hawaiian gangster forces an undercover Kono to strip to her bra and panties to prove she's not wearing a wire.
- Sherlock Scan: Jenna Kaye performs one on a Corrupt Corporate Executive in "Ua Hiki Mai Kapalena Pau".
- Shotguns Are Just Better: Chin Ho's weapon of choice.
- In "Palekaiko", Danno refers to a private investigator being interrogated as "Magnum".
- In "He Kane Hewa' Ole", Steve and Danno spend much of the episode arguing over which of them is more like Erik Estrada. In the last scene, they're watching reruns of C Hi Ps with Kono and Chin Ho.
- In "Powa Maka Moana", McGarrett tells Danno that he'll be back. Danno asks if he'll smash their car into the pawn shop just to get Lono to talk.
- In "Loa Aloha", Danny calls a charter service to get information on a fugitive's travel plans and, not wanting to identify himself as a cop, gives his name as "Clarence Clemons."
- In "Ua Hiki Mai Kapalena Pau", Gracie is seen explaining Angry Birds to Danno.
- In "Kame'e", The Beatles get a mention:
Danno: So, what, you're not going to tell me about "Operation Strawberry Fields"?
Danno: No, no. Of course, you'd have to kill me.... I'm just curious, though: Was there an "Operation Abbey Road"? Were you the walrus? (Joe White gives him a disapproving look) Time to shut up?
Joe White: Roger that. Are you people ready for the magical mystery tour?
- In "Ka Iwi Kapu", Max delivers a Horatio Caine one-liner, complete with sunglasses.
- The episode's Cold Opening is a deliberate imitation of The Blair Witch Project.
- The shootout in "La O Na Makuahine" between Five-0 and Delano's crew is similar to Heat, except that Five-0 gets their man.
- McGarrett calls Danny Boo-Boo in "La O Na Makuahine".
- In "Lana I Ka Moana", Danny and McGarrett are adrift in a boat in shark-infested waters. Danny complains, "Have you ever seen 'Shark Week?' I don't wanna be on 'Shark Week!'"
- In "Ua Hopu", Adam Noshimuri telling his girlfriend, Kono that he will be getting the Noshimuri family out of the Yakuza is very similar to Michael Corleone saying "In five years, the Corleone family will be completely legitimate."
- There's mention of James Bond near the end of "Kapu" when Steve shows up in a tuxedo. Don't forget the music that accompanied his appearance too, since it matches up the 007 opening theme song.
- In "Hoa Pili", Magnum, P.I. is given a nod via Kamekoa's new helicopter tour business, complete with a cover of the iconic theme song.
- "Hoku Welowelo" has a Batman reference when Grover snarks about giving him the "Five-0 Grover" signal. Steve and Danno complain that they don't need it and they don't wanna see him in tights.
- Show Within a Show: Season 3 Episode 21 "Imi loko ka 'uhane" is told from the viewpoint of a morning/daytime show host's perspective. The show films a day in the life of the Five-0 team. The host even calls it a Very Special Episode.
- Shown Their Work:
- Steve wearing the appropriate AOR2 camo, being an ex-SEAL commando.
- "Ho'onani Makuakane" touched up on actual issues with Japanese-Americans being interned in camps in Hawaii after Pearl Harbor was bombed by Imperial Japanese military forces, as well as the existence of the 442nd Infantry Regiment, made up of Japanese-Americans with one Korean-American.
- The Smurfette Principle: Kono has been the primary female in the cast for awhile. While every so often they introduce a new woman to the team, these characters have a habit of getting written off after about half a season. While this season they introduced Catherine as a regular cast member, Kono was offscreen for most of the fall, and now it seems Catherine's getting the same treatment. C'mon writers, America can handle more than one woman investigating a murder/terrorist cell/bank robbery at a time.
- Snark-to-Snark Combat: Between Danno and Tony Archer in "Lekio". With a bit of Reality Subtext here, since the latter's actor is James Caan, father of Scott.
- Special Edition Title:
- In "Hookman", the titles are done in the style of the original series.
- In "Imi Loko Ka 'Uhane", we see the opening credits of the fictional Savannah Walker Show, and the other titles are done in the same style.
- Story Arc:
- The mystery of McGarrett's mom's apparent death, and the contents of the "Champ" box, which leads to McGarrett discovering that the Governor is in league with Wo Fat — just in time to be framed for the Governor's murder.
- The missing money which led to the disgrace of Chin Ho. The arc is resolved in "Ma Ke Kahakai", where it is revealed that Chin's uncle embezzled the money and Chin took the blame to cover for him.
- Danny and Rachel getting back together — or not.
- And, potentially, the fallout of Danno's brother's corruption. Even this one may end up relating to the first two.
- Kono's dismissal from the force, and her resulting involvement with a shady group of ex-cops ("Hana 'a'a Makehewa", "Oia'i'o", "Ua Lawe Wale", "Kame'e", "Mea Makamae") before it was revealed that she was not going corrupt after all.
- Once Doris McGarrett was revealed to have been alive after all all these years, the mystery of her relationship with Wo Fat. Why did she let him get away at the end of the Season 3 premiere? Because, as it turns out, she had raised Wo Fat as a stepmother after she killed his real mother. This fact isn't revealed until the 100th episode, two years after the Season 3 premiere.
- Teeth-Clenched Teamwork: Steve and Danny have very different approaches to the law, though they establish something of an understanding over the course of the pilot.
- This Is for Emphasis, Bitch!: Invoked by Danny to Steve regarding Ms. Pac-Man, of all things:
McGarrett: You ever make it to Double-Pretzel level?
Danno: Triple-banana, bitch.
- Now with commemorative T-shirt!
- That One Case:
- For McGarrett, it's the Story Arc concerning the contents of the Champ box and his father's relationship with the Yakuza and Wo Fat. At least Fat is dead, but now the question is what happened to his father?
- For Chin Ho, it's the drug case where the $28 million was seized. Led to Chin Ho being blamed for embezzling $200,000 of it. Subverted. In "Ma Ke Kahakai" it is revealed that Chin already knows who the embezzler is.
- Uncomfortable Elevator Moment: When a couple of tourists with a little boy find themselves in the same elevator as the Five-0 police officers, fully geared in bulletproof vests and guns out, as they are pursuing a wounded suspect hiding in a grand hotel. Complete with Hawaiian elevator music.
- The Unreveal: We'll never know what Five-0, the HPD and the FBI found in the safe of the serial killer in the end of "Pukana".
- Took a Level in Badass:
- Danny's competency as a cop is often overshadowed by Steve's extreme amounts of badassery, Chin's disgrace arc, and Kono's Fanservice and Badass. But in "He Kane Hewa'Ole", he is the first one who correctly deduces the culprit's plot. Lampshaded by Steve, who asks, "When did you get smart?"
- Max Bergman is tied to a chair, knocks himself over while the bad guy is out of the room, uses a piece of glass to cut the ropes, gets back into position then stabs the bad guy with the shard of glass when he comes back into the room.
- Lt. Catherine Rollins (arguably if she ever was before), who is now part of the regular cast and handled one of the attackers at the end of Season 3 premiere quite well.
- Too Soon: Invoked in-show in "He Kane Hewa' Ole".
Okay, what about our John Doe #2? Danno:
You mean Jack? McGarrett:
You got an I.D.? Danno:
No Ja — his head was in a box. Jack. Chin Ho: That ain't right, bro. Danno:
Too soon? McGarrett:
- Tonight Someone Dies: "Ua Hala"
- Torture Always Works:
- Torture for Fun and Information: McGarrett seems to have taken lessons from the Gene Genie himself when it comes to inventive interrogation:
- In "Pilot", McGarrett threatens to deport Sang Min's family to war-ravaged Rwanda.
- In "Malama Ka Aina", McGarrett and Danno convince an associate of the Samoan mob that they're leaving him in a shark cage with vicious man-eating sharks and chum, when in actuality, the sharks are harmless and the chum is just water. Steve and Danno crack open beers and watch the guy freak out.
- In "Lanakila", McGarrett threatens a corrupt prison guard with a trip to the cell block:
McGarrett: Billy, so help me God, you answer incorrectly one more time, I gonna put those scrubs on you myself and then drop you in general population. How long do you think you'll last there?
- In "Nalowale", McGarrett and Danno witness a suspect drug a girl's drink in a club. Danno tells the suspect to drink it, if he "didn't do anything to it", and if he doesn't drink it, Danno will break his teeth and make him drink it. He drinks it, and passes out. McGarrett wakes him up in an interrogation room with an air horn.
- In "Mana'o", Danno ties a suspect to the hood of his car, then proceeds to drive around the streets of Honolulu like a madman to get information out of him.
Just for the record, if I pulled something like this, you would be reading me the riot act on proper police procedure
No. I'd probably just arrest you. McGarrett:
Compared to this, hanging a guy off a roof and throwing a guy in a shark tank is pretty tame. Danno:
You know what? I disagree. Shark cage is way worse. McGarrett:
Whatever. You're wrong. I'm just saying, to be clear, next time I get a free pass, okay?
- In "Alaheo Pau'ole", Chin and Danno discover a small cache of weapons in a murder suspect's home. When the suspect tells them that the grenades in the cache are fakes, Danno makes him hold one and takes the pin out, which immediately makes the suspect start talking. Also elicits a What the Hell, Hero? from Chin:
Chin: You've been hanging out with McGarrett too long!
- In "Pa Make Loa", Chin and Danno literally pump a suspect for info by threatening to pump him with a deadly virus his boss was trying to buy. They do give him the contents of the vial, but Danno tells the guy later it was a shot of Vitamin B.
- Big Bad Wo Fat was just as fond of this trope as Five-0 was, as demonstrated in "Ina Paha".
- True Companions: Invoked in show in "Ohana", which is the Hawaiian word for Family.
- Truth in Television: In Season 1, the team used to talk on their phones while holding them and driving their cars. Turns out Hawaii has a series of "Hands Free" laws on the books for each County (City & County of Honolulu has an exemption for Law Enforcement if done during the officers official capacity and scope, which could apply to the team). However, in Season 2, the team seems to be using a ton of hands-free devices while driving.
- Undercover Cop Reveal:
- Sid in "Mala Ka Aina".
- Kono in "Ma'eme'e".
- Unwitting Pawn: Hillary Chaver to Delano.
- Vertigo Effect: Used halfway into "Hana 'a'a Makehewa" after showing how Chin Ho wound up with a bomb strapped around his neck.
- The Villain Makes the Plot: Delano makes the plot of Season 2's finale and Season 3's premiere.
- Vitriolic Best Buds: McGarrett and Danno.
- The penultimate scene in "Loa Aloha" exemplifies this. FBI has been hunting Danny's brother, Matt, for Wall Street corruption. Steve reveals to them that Matt has a boat in dock, to which the FBI proceeds to pursue. However, Matt is then revealed to be escaping by his private jet, where only Danny knows its existence. As a cop, Steve does not lie; as a friend, he does not betray Danny either. Danny's quiet "thank you" before leaving Steve perfectly crowns the scene.
- In the Season 1 finale: Danny, in an earlier scene, has promised to catch up with Rachel and Grace at the airport on their way back to Jersey. At the episode's penultimate scene, instead of going to the airport, he catches up with Steve just as Chin Ho arrests the man, swearing that he will get his buddy out. This scene is juxtaposed with Rachel and Grace leaving the airport in disappointment as Danny doesn't show up.
- Wham Episode:
- "Hana'a'a Makehewa". The human trafficker in the pilot, Sang Min, escapes; Victor Hesse returns from the dead; the Five-0 team crosses the Despair Event Horizon by stealing cash from a police evidence locker in order to save Chin's life; and most importantly, Wo Fat appears.
- "Ke Kanohi": McGarrett's sister is kidnapped by the Yakuza, and then Steve discovers the identity of the corrupt HPD officer who killed his mother, who is the brother of the Corrupt Corporate Executive who heads the local Yakuza. McGarrett and Danno arrest the Big Bad on a golf course, not realizing (just yet) that one of the other golfers in the foursome is The Man Behind the Man, Wo Fat.
- In the season 1 finale "Oia'i'o" Five-0 is a little bit messed up. By the end of the episode McGarrett is framed for the murders of Governor Jameson and Laura Hills by Wo Fat, Danny misses the plane while trying to stop Steve so a pregnant Rachel thinks he's abandoning her and Grace, Kono is under investigation for her part in the unauthorized "borrowing" of the $10 million in "Hana'a'a Makehewa," and Chin Ho has apparently abandoned Five-0 for HPD.
- The season 2 premiere ends showing showing Wo Fat kill Hesse while disguised as a prison guard, then leave in a car driven by Kaye.
- In the penultimate episode of Season 2, "Ua Hopu" (Caught), Steve McGarrett arrests Wo Fat with the help of the Japanese police force. The episode ends with Wo Fat entering his prison cell.
- In the season 2 finale, "Ua Hala", Fryer is a victim of Character Death, Max gets shot but survives, Chin Ho is blackmailed into getting Dirty Cop Delano out of prison and forced to make a Sadistic Choice between saving his wife Malia or Kono, who are respectively shot and tossed into the ocean bound and gagged, Danny is contesting custody of Grace because Rachel is moving to Las Vegas, and McGarrett finally learns that "Shelburne" is his mom.
- The season 3 finale's got a couple, including but not limited to Kono leaving Five-O and Hawai'i to go on the run with Adam, Charlie Fong getting stabbed, and Doris promising the truth about Wo Fat to Steve, which she does not, and the question remains unanswered until the 100th episode..
- Speaking of the 100th episode, quite possibly the biggest doozy the show has produced yet. Wo Fat captures Steve for the second time in the program, and, after torturing him for information about his father, reveals that Doris adopted him after she killed his mother by accident, but was forced to abandon him by the United States. This means Wo Fat was Steve's stepbrother all along, which apparently was the secret Doris had kept from Steve during Season 3, and was the reason she did not kill him in that season's opener (and vice versa) when he held a gun to her head. McGarrett is able to escape his restraints, and Wo Fat is finally gets his via a bullet to the forehead from a gun that Steve is able to obtain.
- Wham Line:
- What If?: The 100th episode explored this a bit thanks to Wo Fat injecting Steve with drugs. What if Steve's father had survived? Well, Steve would have stayed with the military; Danny would be a Hawaii-loving, still-married man who employs Steve's interrogating techniques (and who loves being called 'Danno'); Chin Ho would be captain of the HPD; Kono would be a four time world-champion surfer who never joined 5-0; Max would be a doctor at the hospital; Kamekona would be a serious criminal serving time in prison; and Jerry would be homeless and crazy.
- What the Hell, Hero?: Danno does this to Steve on regular basis. (Example: see the dialogue under Deadpan Snarker and Torture for Fun and Information above.)
- Witness Protection: "E Malama"
- World of Snark: With all five of the main cast being top-notch snarkers along with most of the recurring characters and even the villains, you'd think Hawaii is called the Snark State.
- Wrestler in All of Us:
- In "Heihei", McGarrett busts out a standing dropkick, kips up, and then takes the bad guy down with a combination crossface and armbar.
- Kono has started doing kip-ups as well. In "E Malama", she also spears a would-be assassin through a glass door.
- Catherine's another one since she did a scissor kick. But this is a bit of a mix since the attack is also a martial arts move too.
- Wrong Genre Savvy: As the only normal cop in the team, Danny constantly reprimands his buddies for their rather wild, not-exactly-police-appropriate, and, a lot of times, insane approach to the cases. But we know better. Invoked in "Kai e'e". He reprimands Steve for even bothering to listen to Mamo, who claims that he could see no tsunami coming. His scolding is justified since Mamo is a surfer, not a scientist. But then again....
- You Do Not Want To Know: Wo Fat to Steve twice: once in paraphrased form in their first-season sushi shop encounter when he warns him "you may not like what you find" if he continues looking into the circumstances of his parents' deaths, and then with those exact words near the end of the fourth-season premiere, "Aloha kekahi i kekahi". Despite this and other people getting in the way, Steve persists, and he finds out the truth about his mother raising Wo Fat from Fat himself in episode #100, as well as learning that Wo Fat's father is still alive.
- You Have Outlived Your Usefulness: Wo Fat was especially fond of this trope.
- At the end of "Ke Kanohi", the Five-0 team learns that the corrupt HPD officer who (allegedly) killed McGarrett's mother, and who was the next target on Five-0's list, has been found dead.
- Defied by Sang Min at the end of "Ua Hiki Mai Kapalena Pau" — he surrenders to Five-0 because he's a "loose end" and Wo Fat doesn't like to leave "loose ends" alive.
