Belle
Librarians, as Belle learned, were certified observers. They soaked up every detail not only the lives of fictional characters, but the coming and goings of students.
She watched Ruby, who had most likely never read a book in her life, check out a stack of books larger than ten double-decker burgers at Granny's. She witnessed a group of cheerleaders congratulate Regina while Mary Margaret lingered behind, looking unusually sad. Perhaps the most interesting tales took place in the Storybrooke library rather than the story books it offered.
Her heart fluttered a bit every time she caught a glimpse of Rupert Gold. Despite their differences in the past, he played a major role in why Belle's life was the way it was. She couldn't erase her past any more than the fact that she was hopelessly in love with Rupert.
She didn't love him in spite of his flaws, she love him because of them. Loving someone who was already good was like trying to fix a teacup that wasn't chipped.
