The Little Mermaid1989

Triton:
[confronts Ariel in her grotto] I consider myself a reasonable merman. I set certain rules and I expect those rules to be obeyed.

Ariel:
But Dad, I...!

Triton:
Is it true you rescued a human from drowning?!

Ariel:
Daddy, I had to.

Triton:
Contact between the human world and the mer world is strictly forbidden! Ariel, you know that! Everyone knows that!

Ariel:
He would've died!

Triton:
One less human to worry about.

Ariel:
[angrily] You don't even know him!

Triton:
Know him? I don't have to know him! They're all the same: Spineless, savage, harpooning fish-eaters, incapable of any feeling.

Ariel:
Daddy, I love him! [gasps, as she has accidentally slipped the truth]

Triton:
[shocked] No. Have you lost your senses completely?! He's a human! You're a mermaid!

Ariel:
I don't care!

Triton:
So help me, Ariel, I am going to get through to you. And if this is the only way, so be it!

[He proceeds to destroy most of the grotto with his magic trident]
