"There has to be something we can do. If we don't act now everyone will die."
"I know, Tama, but who can help? There's no one-"
"Find someone. I know you can. I'll stay here, distract Scar so that he doesn't realize you're gone. You have to get away. You have to find help."
"Nala, you're our only hope."
Just a bit of a scenario I came up with. Just before Nala left to find help. Maybe she needed a bit of convincing to go?
