Carmen: "From one great lady to another, Catherine. Let's go play in a warmer climate for a while, shall we?"

The Player and Carmen.

Player: "This time I'm coming out ahead, Carmen."
Carmen: "It's not whether you win or lose the game, Player, but how much fun you can make it for me while we play. I have the statue, now it's your move."

Zack meets Tatyanna.

Tatyanna: "I'm Tatyanna from the Acme Detective Agency in Moscow."
Zack: "I'm uh... uh..."
Ivy: "Oh, Zack."
Zack: "Yeah, Zack."
Tatyanna: "Come. I brought some warmer coats for you both."
Zack: "Yes! Thank you, Chief!"

I think he likes her...

Zack: "Huh, that's such an exotic name. Tatyanna..."
Ivy: "Uh-hmm. Mind on the case little bro."

Zack knows where Carmen is going.

Tatyanna: "Zack! I am very impressed!"
Ivy: "You'll change your tune once you see him open a bottle of soda. It's not a pretty sight."
Zack: "Yeah, I love you too, Ivy."

I love this one...

Tatyanna: "You're brother Zack is so, um, how do you say it in English...?"
Ivy: "Hmm, desperate to impress you?"
Tatyanna: "Well I was thinking brave but..."
Ivy: "Trust me, the word is desperate."

Confrontation on the German castle.

Carmen: "So glad you could make it."
Zack: "What's your game this time, Carmen?"
Carmen: "One we can play out completely, now that you're here, detectives."

Ivy falls off the castle.

Carmen: "Give me your hand!"
Ivy: "Never!"
Carmen: "Don't be so childish, Ivy. I'm trying to help you."
Ivy: "I'll take care of myself."

Didn't Ivy use this line on Lee in "Boyhood's End Part 1"?

Zack: "Yes! Tatyanna, I could kiss you..."
Tatyanna: "Oh, I never kiss on the first case."
Ivy: "Oh, please."

Playing on the Big Island.

Carmen: "Welcome detectives. You've been my most worthy adversaries. I know you'll give me a good game."

Carmen gets away.

Ivy: "Wouldn't you know it. We got last year's model."
Zack: "What do we do now?"
Ivy: "Paddle."

The Player and Carmen.

Player: "You planned a winner-take-all match, and my detectives beat you, Carmen."
Carmen: "Ah, but we never really got to play. Looks like a stalemate, until next crime, Player."
