Afraid of Blood: She's not absolutely terrified of it or anything, but she finds it highly unpleasant to be around in large quantities.
Angst? What Angst?: Taffy seems to be completely impervious to all of the terrifying and downright awful things that keep happening to her. For a while, anyway.
Blood-Splattered Innocents: Happens quite often in the story, but Taffy's experience is particularly notable as its her own blood she's splattered with.
Fatal Flaw: Taffy is far, far, far too trusting of people. She truly believes that there is good in everyone. She even empathizes with Henley. She refuses to recognize this despite Errol's pleas, and when she comes face-to-face with the one person who truly has no redeeming qualities what-so-ever, she is effectively broken.
Flaw Exploitation: Henley recognizes Taffy's trusting nature the moment he meets her and uses that to his advantage over and over again. Errol also uses this to his advantage, as does Adrian and Leah, to a degree, though they aren't really doing it intentionally. In fact, the only one who doesn't take advantage of Taffy's kindness is Anton, and that's because he simply doesn't care enough to bother.
Headphones Equal Isolation: Averted. When Taffy gets annoyed she sticks in her headphones to block out the annoyance. To her dismay, she discovers that her astute vampire senses make it almost impossible to block out what others are saying as she can hear them through the music.
Fatal Flaw: Selfishness. Though he tries (later in the book, anyway) to look after the people that he has come to care about, the bottom line for him will always and forever be self-preservation.
Fatal Flaw: Pride. Henley, instead of admitting he has an illness and needs help, assumes he is simply on a higher plane of evolution than his fellow man and goes about creating a race of highly evolved humans just like him. He is the only character in the book to never refer to himself as a vampire.
Functional Addict: Adrian is by far the most successful vampire ever to integrate into human society without having to sacrifice her need to feed on human blood.
All Take and No Give: After she's turned into a vampire. Before then, she's quite the opposite.
Beware the Nice Ones: Maria was likened to a gentle, loving, angel of a woman when she was alive. After being tortured and turned by Henley, however...well...
Fatal Flaw: Maria's downfall was her beauty. Presently, she's far too insane to have one quality that can be pinned down as a flaw. Maria is a fatal flaw.
