Kovu was somewhat shocked when the cub started growling at her. "What? Who are you?" He asked. Yes, they Outsiders were rough, but cannot be trusted? The only reason why they are able to survive in these lands is because they trust each other. He tried to walk around the cub to get a better look at her, but she simply jumped so that he was always facing her.
Kovu found this behavior odd, and even slightly funny. "What are you doing?" he asked, starting to grin a little.
