There's something on your robe [when a red spot from a sniper sight appears]..

McGarrett [to Ramirez]

Grover: You do speak Spanish, right?
Danny: Spanish? I barely speak English.

Turn your nose up at Mr. Franklin and you get Mr. Heckler and Mr. Koch. They can be pretty persuasive.

Grover

Ramirez: You are chaos.
McGarrett: You really should meet my partner. You guys would get along great.

Chin: It was because of our dealings with Diego that Sara was taken.
Kono: Chin, you can't blame yourself.

Bridget: You know, I've heard a lot about you.
McGarrett: And some of it was good.
Bridget: Mostly.
McGarrett: What's that mean?
Bridget: My mother called you a catch.
McGarrett: I love your mother.

Kono [to Chin]: I think you might have taken things too far. Multiple background checks, having a judge delay the adoption, you even used Sarah to recon their house. If I was them, I wouldn't want you in Sarah's life. Cuz, I love you, but you're going to have to make things right with that family if you want any kind of relationship with Sarah.
Chin: You know what? You're right.

Danny: I think you might be right.
McGarrett: That's very good news. Care to elaborate?

Danny [to McGarrett]: This is how he touched her [touching McGarrett's lower back].
Kono: I can come back.

You think I'm over-reacting, that I'm being ridiculous about this thing with Bridget. I know these things, just like I knew Grace had a boyfriend.

Danny

Bridget: I'm sorry. Unlike you, I just can't walk away from my children.
Danny: My children can look me in the eye and know that I never lie to them.

Yang: Ten years I was chasing the wrong guy. What kind of cop does that make me?
McGarrett: It makes you the kind of cop who cares. Those years weren't wasted. You kept Maggie's memory alive, and now you get to call her parents and tell them we found her killer.

Hawaii Five-0 Quotes

Steve McGarrett: What kind of sick bastard kills a cop in cold blood?
Danny Williams: One with a serious grudge.

Danny: Boxing or MMA?
Grover: Boxing, no question
