In Shakespeare’s The Tempest, Caliban has a neat turnaround, as do most of the characters, fulfilling that most earnest story convention. Caliban says

You taught me language; and my profit on’t
Is, I know how to curse. The red plague rid you
For learning me your language!

then

Ay, that I will; and I’ll be wise hereafter
And seek for grace. What a thrice-double ass
Was I, to take this drunkard for a god
And worship this dull fool!

The initial quote from Act I and ending with Act 5 both point to language and knowledge. While it’s not the most likeable end for Caliban the technique remains sounds. It’s that nice arc.

There’s Finding Nemo, too. At the end Nemo’s father finally let’s go of Nemo in the fishing net and gives him “will,” a thing Caliban won’t be given. In the whale’s mouth, Marlin gives Dory trust. In Syberia, Kate Walker is bound on getting her business done then going home and at the end chooses not to. So the stories go.
