YMMV / Uglies
Tally Youngblood=Buffy/Willow, Shay=Faith,David=Angel, Zane=Spike, Dr. Cable=Glory,
Croy=Xander, both of them are skeptical. Xander doesn't trust Angel and for most of Uglies Croy doesn't trust Tally. Aya Fuse=Dawn
- Les Yay: Shay gets awfully jealous whenever Tally gets a boyfriend. This arguably becomes Foe Yay later on as Shay becomes more and more villainous. Somewhat intentional — the author purposely used gender-neutral terms when Shay asks Tally where she got her locket in Uglies.
- Moe: All young Pretties have to look young and vulnerable.
- Moral Event Horizon: Dr. Cable crosses it in Uglies when she kills Az while attempting to operate on his brain in the hopes of removing his memories as well as adding lesions. To make it clear she's the antagonist in Specials, she hides evidence that Tally and Shay accidentally destroyed a museum to have an excuse to declare war on Diego for housing the runaway uglies, and then imprisons Tally when she returns home to confess.
- Older Than They Think: A new reader picking this up might dismiss this as a Hunger Games or Divergent clone - except it was written three to five years prior.
- Unintentionally Sympathetic: It's really hard to hate Shay when you consider that she has legitimate reasons to act villainous. Trusting your best friend with all your secrets only for her to steal your boyfriend, destroy your home, get you kidnapped and have a mind-warping chip put in your brain must really suck. This was Scott Westerfeld's intention, to show that Tally and Shay could never really be "best friends forever" as Shay creepily puts it at the end of Pretties. Although Tally isn't completely to blame, as Shay's Story points out, they still end up at odds from the trilogy's beginning to end.
