- Raphael: Drop the blades, sweetheart.
- Alopex: My name is Alopex, turtle boy.
- Casey Jones: Haha! Turtle boy!
- Raphael: It's Raphael! Now put 'em down.
- Alopex: Well, Raphael, allow me to give you a history lesson on the Blades of Vengeance. Centuries ago, they were owned by twin sisters. They used them against an evil warlord who had slain their family. The blades cursed any man who was even scratched by their steel.
- Splinter: Unorthodox methods may sometimes be necessary in order to defeat the enemy. Yet you should also be prepared for your enemy to do the same. Therefore, you all must learn to hone your intuition. Leonardo and Michelangelo have the strongest ability to sharpen their intuition. Anger clouds too much of Raphael's foresight. Donatello's too grounded in his rational mind. Only April's is near perfection. Casey, your intuition is basically 0.0.
- Casey Jones: Casey Jones is a born warrior. I got tons of intuition, yo.
- [Splinter slaps Casey's mask down]
- Splinter: Did you intuit that?
- Rocksteady: What is matter with kitty cat man?
- Bebop: Maybe ol' T. C. been hitting that catnip too much. Chill, kitty cat!
- Tiger Claw: The one who took my tail has finally come for me.
- Rocksteady: So who is the Alopex, Comrade Claw?
- Bebop: Yeah, and why are you so afraid of her, dude?
- Tiger Claw: I am not afraid of her. It is much more complex than that. Listen well.
- [Flashback]
- Tiger Claw: We were children. A portal opened in our small village, and thinking it was a magic door, we entered. The Kraang mutated and experimented on us. But after many months of hardships, we escaped through a portal back to Earth. But we were monsters now. We could not return home. And so we fled. We found refuge in a circus sideshow. But our skills were much too valuable. Soon we became top-level assassins in the criminal underworld. We were notorious and feared. But then... she turned on me! And tried to kill me, but only ended up cutting off my tail. Although she escaped, I was certain the wounds I inflicted upon her were far too grave for her to survive. I was wrong.
- [End of flashback]
- Tiger Claw: She believes that I destroyed her life. She must have spent years searching for me. But now, it is I that will have vengeance.
