She nodded, offering Christine a smile, "Very beautiful." She replied, "They have pretty voices, big colors, and powerful tails." She said, bell-like voice chiming softly as she mouthed the human words. She didn't expect Christine to believe her, humans didn't usually have very big imaginations unless they were smaller, around the age of a boy or a girl. But they were real and Tinker Bell knew this to be fact, wether anyone believed her or not.
She had no reason to lie to Christine, it was in her nature to lie only to get herself out of trouble and even then she wasn't that good at it, mostly it was so Peter wouldn't be too upset with her for causing mischief.
When Christine pulled the scarf from the others, Tink clapped her tiny hands in delight, and flew once around the room in excitement, pixie dust shimmering over everything, though it didn't stick to anything at all. When she was done being excited, she fluttered back to Christine, wondering what would happen next.
