At the suggestion of leaving, Tinker Bell nodded at Christine, waiting for her lead, considering that the tiny pixie had no idea where she was even going.
Once Christine was on the ground, as humans really should be, Tink flitted over to her, hovering in the air. When Christine mentioned a car, Tink made a confused face, not knowing what a car was. "What's a car?" Tink mouthed, unfamiliar with the technology from this world. She knew about houses, and dogs, as well as books and she knew how to write human language as well as read it, since Peter had taught her in case she ever got into trouble somewhere in the real world.
She figured that Christine wouldn't do anything to hurt her, so she was willing to at least see what a car was, after that point, however, there were no promises.
