When Jasper goes into the Pridelands to seek out Vina to finally apologize, he meets Kiara. He is a little confused about why the pride acts the way they do, due to his fallen kindness, so he asks Kiara about it. Then, when she realizes he knows almost nothing about being a real lion anymore, she starts to teach him.
"Lesson number 1, Jasper, is to roar.", Kiara explained to Jasper. "I know how to do that already, princess.", he said back, snarling at the word princess. Kiara looked unsure and said, "Fine, prove it.". Then when Jasper tried to roar, only a meow came out. "Yeah, you really know how to roar, Jasper.", Kiara said as she giggled a little. Then she added, "Like this,", and then she roared, as Jasper looked shocked.
