- Tiger Claw: You will pay for what you did to me. The suffering you caused, the pain I endured!
- Casey Jones: You're not still mad about the whole worm thing, are you?
- Raphael: Casey? Casey? Casey, answer me! Something's wrong, Mikey, what're we gonna do?
- Michelangelo: I know exactly what to do! We use our phones to triangulate the position of Casey's T-Phone by bouncing the locator signal off the satellite.
- Raphael: That's... actually a good idea. It's like we're in some kind of alternate universe, or something.
- Michelangelo: You can also track pizza delivery guys that way. Booyah-kasha.
- Splinter: I retain very little from my old life, but this I will never let go... My daughter.

- Karai: [stunned] I... I can't believe it. You're telling the truth...! All these years the Shredder has been lying to me...
- Leonardo: Wait, you can't believe it? I thought you DID believe it. If you didn't believe it, why did you come down here?
- Karai: Father... What have I done?
- Raphael: Well, Princess? You got us into this. Where to?
- Karai: I... I don't know.
- Michelangelo: EVERYONE STOP! I know exactly where to go!
- Donatello: I feel scared...
- Karai: There's no honor in this...
- Tiger Claw: [beating up Mr Murakami] I didn't come here for honor.
- April O'Neil: You wanna do this, Karai? Fine! But I'm warning you, I've been training with Master Splinter big time! And I'm ready to kick your butt!
- Karai: I didn't come to fight. I came to talk.
- April O'Neil: Oh... Well, I've been trained in that too.
- Tiger Claw: I have returned...
- The Shredder: Tiger Claw.
- Karai: How? You were eaten by a giant alien worm!
- Tiger Claw: And you believe that such a thing could contain my hate? My hate is what kept me going. As I tore my way out of the belly of the Kraathatrogon. As I battled through the armies of the Kraang. Across alien worlds that would drive lesser men mad! Finally, back here. Back to my enemies. I would have my revenge against Splinter. Against his hideous reptiles. And against those who trapped me in that wretched worm's belly!
- Donatello: He's still brooding.
- Raphael: He's thinking about her. About Karai.
- Leonardo: Master Splinter is her father. How could she still want to be with the Shredder?
- Michelangelo: You have to have faith, Leo. Her entire relationship would be a lie. It would change everything she knows. The truth will set her free. Just give her the time she needs to accept who she is!
- Donatello: Right... Look, Leo, she'll come around.
- Tiger Claw: [defeating Leo] Karai, would you like the honor of finishing him?
- Karai: I have no honor... But that's about to change!
