Tinker Bell could see how Christine might not believe they existed, but Tink knew, and although she didn't care much for the mermaids, she tolerated them because all of the mermaids hated Wendy too. That was a point they all agreed on, and that made them okay in Tink's tiny eyes. When it came to Peter, though, she would never be on the same level. Peter was a heartbreaker, and he had no clue how important he was to so many people and creatures. Oh Peter.
Tinker Bell fluttered over to a small table in the room, one that seemed willing to give enough space for the tiny pixie to be measured, trusting Christine with the task of taking her measurements. The idea of having a new dress excited the small pixie, and her wings fluttered, though she didn't leave the ground.
She looked up at Christine, waiting for the next move, willing to cooperate with Christine if she needed anything. It was kind of nice having a new friend in a strange world. Not to mention a friend with such nice things.
