Danny Williams: What if we are the only people left on earth, then what? What are we supposed to do? Repopulate?
Tani Rey: That’s a hard no.
Danny Williams: A big, empty, radioactive wasteland. Just a barren, ugly space, but we will all be safe and cozy in this miserable box. I mean, that sounds worse than death to me, you know? Being stuck in here, respectfully, with all you people. And let okay, you remember, um uh, quarantine? It'd be like that, only forever.
Steve McGarrett: What’s the opposite of a motivational speaker? Cause whatever that is...you’re that.
Lou Grover: “Yeah, I don’t know. No, I...I think my man’s got a point.
Tani Rey: Yeah, I'm going to take the missile.
Steve McGarrett: (barks) I didn't ask you.
Danny Williams: (cheer) To a to a fiery apocalypse.
Danny Williams: Love you.(bump fists)
Lou Grover: Um, well, this here is Officer Tani Rey. And we're with the Five-O Task Force. And today is your lucky day because the boss was in such a good mood, he decided to send over two of the more affable members of the task force just to have a little chat with you.
Criminal: What's that?
Tani Rey: It means service with a smile.
Kazuya Nemoto: I know my rights. I don't have to talk to either of you.
Tani Rey: All right, fine, you can just listen. I mean, after all, we know how this conversation is gonna go, right?
Lou Grover: We do.
Tani Rey: Why don't I help you? We're gonna start by saying that we know that you were responsible for the robbery at I.X. Chemical last night. You're gonna say, ‘What? Me? Pfft. No! I'm not responsible for that’ We're gonna say, ‘That's not what we heard.’ And then we're gonna show you this. (Video)
Kazuya Nemoto: That dude will say anything to save his ass, but he's got no proof. Plus, you really think the uncorroborated testimony of a guy like that is gonna stand up in a court? Assuming, of course, that he even makes it alive to testify.
Lou Grover: Oh, that's dark.
Lou Grover: You're a marked man now, buddy. Which is good for us, 'cause we got a pool going as to which one of you's gonna drop first, you or Roland. My money's on your ass.
Junior Reigns: Hey, you okay?
Danny Williams: Yeah, I'm fine. What, uh what do you think the symptoms are of being exposed to this stuff?
Junior Reigns: I don't think we were exposed.
Danny Williams: Why-why do you say that?
Junior Reigns: Well, chlorine gas is a lot heavier than oxygen. Unless it was intentionally dispersed, it just settles. Most of it would've just stayed contained inside the van.
Danny Williams: Oh. What, are you an expert now?
Hazmat Tech: All clear. You guys can go in.
Danny Williams: Oh, excuse me. Uh, my friend, he told me that he doesn't think that we got exposed. We were in that house for a little while. I'm curious-- in your expert opinion, what do you think?
Hazmat Tech: You're fine.
(Turns around to see Jr. standing directly behind him)
Danny Williams: What, do you feel like a smart guy now? Like you know everything?
Junior Reigns: No.
Law Student: Hey! You and your friends want to zip it? This is a library.
Tani Rey: Yeah, babe, and this is a badge. You want see the gun?
Odell Martin: Next time you feel the urge to pick up a pair of clippers, don’t. I mean this is...this is a travesty.
Steve McGarrett: What are you talking about?
Odell Martin: You call.
