Lincoln Cole: Honestly, Marshall Nang is pretty much the only person outside of Langley with a shot at decoding that cipher. Actually, scratch that. There is someone else. A Naval Intelligence officer I met a couple years back. Super smart. She'd be up for the job, too. But I.. I lost track of her.
Steve McGarrett: Mm-hmm. Her name wouldn't be Catherine Rollins, would it?
(Lincoln looks at Steve with surprise)
Lincoln Cole: You know her?
(Steve gives a sad smile)
Steve McGarrett: Yeah, I know her, man. She was my girl. We were together for a bunch of years, but, uh... well, these intelligence types, they got a habit of, uh... disappearing on you, you know?
Lincoln Cole: Mm. Sounds like it was serious.
Steve McGarrett: Well, she was the one that got away. What are you gonna do?
Lincoln Cole: Hmm.
(Steve has Intensity face on)
Steve McGarrett: One sec.
(Steve answers using the hands free of the vehicle)
Steve McGarrett: Yeah, Danny, what's up?
Hey, Steve, I got a crazy tail on me and they are not being discreet at all.
(Danny is driving the Camaro with 2 SUVs tailing him)
Steve McGarrett: Where are you? Send me your location.
traveling east on Kapiolani, just passed University.
Steve McGarrett: All right, hang tight. We're on the way.
(Steve shifts the truck in gear and tears out to get to Danny)
All right, do me a favor and hurry up. They're all over me, Steve. They're up my ass, all right? I just went under the H-1.
( Steve has his siren on as he drives to get to Danny )
Steve McGarrett: Okay, cop-copy that. Listen to me, we are headed to you now, okay? We're on the way, Danny.
( gunfire sounds over the call )
(Steve gets Constipated face on)
(the sounds of tires skidding comes over the call)
Steve McGarrett: Was that gunshots?
(Lincoln and Steve have worried faces as more gunfire comes over the call)

(conversation over cellphone)
Steve McGarrett: Who is this?
Daiyu Mei: My name is Daiyu Mei. I believe you knew my husband, Wo Fat.
Steve McGarrett: Do you have Danny?
Daiyu Mei: Correct. In fact, it seems we each have something that the other person wants. I have the person that you care about most in the world, and you have something that is rightfully mine.
Steve McGarrett: What do I.. what do I have? What do I have that's yours?
Daiyu Mei: The cipher. Deliver it to me and Detective Williams lives. And... don't insult me by pretending you don't know what I'm talking about. Assume I know everything.
Steve McGarrett: How do I know he's okay?
(Daiyu Mei enters the room that Danny is being held in)
Daiyu Mei: Say hello to your friends, Detective Williams. They're concerned for your safety.
Danny Williams: Whatever she wants you to do, Steve, don't do it, okay?
Tani Rey: (off camara) Oh, Lord.
Danny Williams: Don't give her anything.
Daiyu Mei: So, do we have a deal?
(Danny grunts, uncomfortable in his restraints)
Daiyu Mei: Don't make the same mistake you made with your father, Commander McGarrett. Don't allow a loved one to die because of your stubbornness.
(in the back seat of Steve's truck with Tani Driving)

(Rest of 5-0 following behind with lights and sirens on)
Steve McGarrett: (on his cellphone) This is Commander Steve McGarrett of the Five-O Task Force. I got a patient coming in. GSW to the chest. All right? I need surgeons prepped and ready for him when I get there. I'm bringing him in myself. All right? Yes, good. Go!Go! Go!

Danny Williams: We're fighting?
Steve McGarrett: (seriously) Buddy... I, uh... I thought I lost you there, man.
(Steve has a light version of constipated/worried face on)
Danny Williams: Nah. No, you can't get rid of me that easy. All right?
(Steve is still upset)
Danny Williams: You know, when a patient wakes up, you're supposed to be relieved. At least act happy, a little bit.
Steve McGarrett: (worried/stressed/relieved) (softly) I'm happy.
Danny Williams: Yeah?
(Danny looks at Steve with his guilty/worried face)
Danny Williams: Yeah, me too.
Steve McGarrett: (irritated) She used you to get at me. She almost killed you.
Danny Williams: Eh, she didn't. I'm right here, I'm chillin'.
Steve McGarrett: Yeah. It's just... It feels an awful lot like what I went through with my father, that's all it is.
Danny Williams: Stop, please. You're annoying me already.
(Danny knowingly breaks the mood and starts throwing smack at Steve to get him to stop with the guilt)
Danny Williams: If I had a dollar for every time you saved my life...
(Steve lets him)
Danny Williams: I'd have, like, 20 bucks or something like...
