There are so many great sides of dialogue and exchanges in this script, but I'll zero in on two sides from Elsa:
Elsa Korr: You're not a Nazi, Jojo. You're a ten-year-old kid who likes dressing up in a funny uniform and wants to be part of a club.
Elsa Korr: Your mother took me in. She's kind. She treats me like a person.
Both sides speak to the most fundamental aspect of what's going on in a story and that is this: Characters moving from an inauthentic life to an authentic life. In order to do that, they have to answer the question: Who am I?
Elsa tells Jojo a truth: He is *not* a Nazi. He's a ten year-old kid. As he dispatches his inauthentic Nazi self, his true nature emerges: a thoughtful, sensitive youth capable of feeling love for another human being.
Then Elsa speaks another truth: Rose, Jojos' mother, 'sees' Elsa for who she is -- a human being. This goes back to the point I made in the Theme discussion, how characters often move from an I-It relationship to an I-You. That dynamic lies at the core of 'Jojo Rabbit.' And these two sides of dialogue reflect that.
