Kiara defies her father and runaway/Jiminy and his friends help Kiara

Here is how Kiara ran away to find Kovu in Jiminy Cricket and Simba's Pride.

Back to Pride Rock, Simba is standing at the tip of the promontory, staring off into the distance.

Kiara: Daddy.. please reconsider! Simba: You will not go anywhere without an escort from now on. Kiara: No! That's not-- Simba: Don't you see he used you to get to me! Kiara: No! He loves me... for me! Why are you doing this? Simba: Because you are my daughter! You will not leave Pride Rock. You will stay here where I can keep an eye on you... away from him. Kiara: You don't know him! Simba: I know he's following in Scar's pawprints... and I must follow in my father's. Kiara: You will never be Mufasa!

{Simba is stung, but silenced... Kiara breaks down and runs back to her den to lie down, sobbing.
