Teenage Mutant Ninja Turtles, Season 4

[The episode begins inside the turtles’ lair, as Leonardo and Splinter spar.]

Leonardo:
I already told you, I’m fine.

Master Splinter:
You are sure?

[Michelangelo lowers his comic book and grimaces.]

Leonardo:
Nothing’s the matter, Sensei. Why do you keep asking me that?

Master Splinter:
So much anger. The unopened bottle will burst when its internal pressure becomes too much to bear. [Donatello spots Raphael at the weight bench.] For months now you have been brooding, surly, and stubborn.

[Donatello appears worried.]

Leonardo:
Yeah, right.

[Donatello and Raphael glance at one another. Shift to Splinter and Leonardo, who are sparring with swords.]

Master Splinter:
You have not been yourself. You must release what festers within you. Your family will help you, Leonardo. It is important that we be open with one another.

[Leonardo attacks and manages to disarm Splinter. He then angrily confronts his father.]

Leonardo:
Open?! Okay, this Katana lesson stinks! I've mastered this years ago! YEARS AGO!!

Master Splinter:
[stares at him and then retrieves the sword.] It is not the students choice to say when a lesson is learned. [He attacks.] The student’s place is to listen and learn.

[The sparring grows fierce and the other turtles gather to watch.]

Michelangelo:
Something tells me the cork’s about to pop on that unopened bottle.

Raphael:
That hothead. [Donatello and Michelangelo look at him] I hate it when Leo reminds me of me.

Leonardo:
I've already mastered this lesson! [shoves Splinter.] And yesterday's lesson! And the lesson before that! WHEN ARE YOU GOING TO TEACH ME [disarms Splinter.] SOMETHING I DON'T ALREADY KNOW?!!! [slashes at Splinter and slices his head. The other turtles run to their father as he drops to one knee and grabs his head.]

Donatello:
Master Splinter!

Michelangelo:
Are you okay?

[Leonardo drops his sword.]

Raphael:
Leo, what the shell is your problem!?

Leonardo:
[shoves past Raphael] Master! [and Donatello] Master, I’m so sorry. I-I didn’t mean to hurt you. I just… I just lost control. [He hangs his head.]
