Uf... Hard choice anyhow.
Definitely, I adore that Kiara's "You will never be Mufasa!" So strong, and meaningful sentence.
But I also like:
Zira: "You've killed your own brother!"
Kiara: "Our place is with our pride. If we run away, they'll be divided forever."
Nala: "I can see them down there just as easily as you can. Get to know him and see."
Vitani: "Kiara's right. Enough."
Kovu: "I've never heard the story of Scar that way. He truly was the killer."
Vitani: "Where's your pretty daughter, Nala?"
