Navi's first really big smile - her first smile that identified her as being Navi - happened when Jack jumped into her arms. She nuzzled into his neck, kissing his fur and nodding at Sable's statement. "I do, yeah. And Miniver too. He doesn't eat enough," she mumbled while looking at him.
She smiled at Sable as she was tucked in, shaking her head a little. "Thank you. And when you're sick, let me know so I can help you, okay?"
