Uglies Friendship Quotes

How we cite our quotes: (Chapter.Paragraph)

Quote #10

She felt exiled, shut out from the one thing that really mattered. (47.29)

The "one thing that really mattered" in this quote is David. Some change: at the beginning of Uglies, Tally wants to be pretty with Peris; at the end, she wants to be ugly with David. Is her change really all that significant? Or has she just transferred her "best friendship" from Peris to David?
