Higgins: I thought I asked you to wait by the vending machine.
Ella: I figured that was more of a suggestion.

It seems our old case just got a lot warmer.

Higgins [to Ella]

Ella: So you're hacking them.
Higgins: Of course not. That would be improper.
Ella: And illegal.

Bob: You want to grant an old man his dying wish?
Magnum: Yes, of course.
Bob: Then scram. And take this fake steak with you.

Higgins: Ooh! You're looking dashing! New shirt?
Rick: Nice of someone to notice.

Rick: Bottoms up!
T.C.: You know I love taste-test day!

Rick: Relax. Mahina doesn't remember you. You're fine. You've got nothing to worry about.
Kumu: Yeah. It won't be weird unless you make it weird.
T.C.: Thanks, guys. Very helpful.

Katsumoto: If you know what's good for you, you're going to stay the hell out of this one.
Higgins: Well, that could have gone better.

Kumu [to T.C.]: What'd you do?
Rick: What makes you think he did anything?
Kumu: An innocent man doesn't hide behind a tent flap when he sees a pretty girl.

Higgins: Are you sure it's [Ryder]?
Nora: Believe me, I wish I wasn't.

Maleah: Why are we doing this again?
Higgins: "Running Diamond Head is the key to an ass that doesn't quit" were your exact words, I believe.
Maleah: Yeah, that sounds like something I'd say.

Magnum: You all right?
Tia: No. You just shot me.
