Karai and April in “Unfinished Business”

What makes you so special!!? You're the center of an alien conspiracy, protected by mutants, and trained by a great ninja master!! Why!!

I don't know!! I'm flunking trig! My friends are mutants! Aliens got my dad! And I lost my mother!

What? You lost your mother?

[recalls what Splinter had told her about unbalancing her opponent] AHHH!! [Flips Karai down the subway steps] Not bad for a nobody.
