Hawaii Five-0/YMMV

Complete Monster
- Nicole Duncan, the culprit in "He Kane Hewa'ole", kills the dying-from-cancer husband and tricks the father into thinking that she has been kidnapped to get five million bucks.
- Wo Fat
Depending on the Writer: Happens with the utility of the Five-0's technology.
Fan-Preferred Couple: Steve/Danny. The sheer amount of fanfiction, communities, and board threads devoted to them are staggering.
He's Just Hiding: What McGarrett suspects is going on with his father's murderer, terrorist Victor Hesse, after shooting him off a cargo ship. He orders the Coast Guard to try to find his body. They haven't, but insist they'll keep looking. 'Course, it turns out McGarrett was justified in his caution.
Ho Yay: So much between Steve and Danny, CBS made a promo out of it. There's a reason they're the Fan-Preferred Couple.
Marty Stu: McGarrett approaches this rapidly. Even lampshaded by Chin Ho after witnessing McGarrett call in a favor with a serving (female) naval officer.

Chin Ho: You convinced her to task a top secret military spy satellite and you got a date?

Narm: In "He Kane Hewa'ole", Five-0 finds a cardboard box with a human head in it. A very, very fake human head.
Paranoia Fuel: Wo Fat has a habit of rigging claymore mines on people's cars, which will detonate once the ignition slot is keyed.
Tear Jerker
- In episode 3, "Malama Ka Aina"

Danno: Rachel, just hear me out. Before you sic your lawyers on me, I wanna remind you of something. I moved 5,000 miles so that I could see Grace twice a week. Twice a week, okay? That is 48 hours, 52 times a year for a grand total of 2,500 hours. When you factor in sleep, and school, I can really only count on 400 hours of real face time each year. And ya know? That's only going to shrink as she starts making friends... Then she goes off to college... So ultimately that does not leave me with a lot of time to spend with my daughter. Not as much as I would want. But I never complained. I never complained. Because every single one of those minutes reminds me of what I am doing, and why I am here. That little girl is my life. So I am asking you- I am begging you to please- please just be kind. Don't take her away from me, that's all.

Unfortunate Implications
- Doesn't Chin look so damn cool riding his Harley! Well, guess what, he's a cop, and he does not wear a safety helmet.
  - Strangely enough, there are no enforced helmet laws in Hawaii. The police department (or government task forces) may require it for on-duty personnel, but it's technically not illegal.
- Five-0 is given immunity from any red tape, and boy how cool and fast they solve cases! But guess what, red tape exists for a reason: it is to tame passion of the government, to protect people from the state. Sure, Five-0 close cases, but what if they convict wrong person? Lampshaded by Sang Min the human trafficker, who after Steve threatens to deport his Rwandan family back to their warring country, forlornly complains, "What kind of cops are you?"
What an Idiot!: The Yakuza boss forgets to clear his fingerprints off the stolen Champ box and throws it in the dumpster outside his own bar -- leaving just enough clues tying him to the kidnapping that Five-0 can arrest him.
The Woobie
- Malia, Chin's ex-fiance. We meet her in He Kane Hewa'ole, and from everything we've heard about her from Kono and what we know about what happened to Chin, it's expected that she's the kind of lady who was willing to dump him after he was disgraced. Instead Malia is a nice lady who loves Chin, was the one dumped for her own protection, and she still wears her wedding ring on a chain around her neck. She tries to be nice to Kono who hates her, and she's so awkward around them both... Poor lady.
- Stoic Woobie: Chin takes the fall of his uncle's embezzlement and ends up being disgraced from HPD, disowned by his cop-pride family, and separated with his fiancee. He trades his house's deed for cash to essentially bribe HPD to stop further investigation.
