- Angst? What Angst?:
- Both averted and played straight, depending on the situation; it kind of becomes necessary with the Trauma Conga Line.
- Still, averted frequently like when Seth thinks Kendra died and the times when Kendra thinks her family and friends are in danger of dying, but there are moments when a character experiences a crude death but the team has to keep moving.
- He's Just Hiding: Grandma and Grandpa Larsen.
- Hilarious in Hindsight: Try reading the books during the 2012 election and NOT laughing at Vanessa Santoro's surname, which is only 2 letters away from that of Pennsylvania ex-Congressman Rick Santorum. The name becomes either funnier or more disturbing when you know that, according to Google, his name basically means "ass juice."
- Magnificent Bastard: The Sphinx. He plays so many games on so many fronts that no one can keep up with him. He abducts and clones Kendra at a time when she's under constant watch, manages to be the leader of the good guys, half of the missions end up with the reveal that they did his work for him... oh, and did I mention he does this all while remaining one of the most amiable characters in the series? He gets Out-Gambitted by Graulus and Nagi Luna, and he switches sides and skillfully maneuvers their doom. In the end, he does so well that they make him an Eternal, making sure he will have to die to open the prison. The Fairy Queen says he's sincere, but he still got what he wanted in the end. Oh, and that fifth secret preserve no one has been able to find? He went there as a slave when he was a child, and rose to leadership of it.
- What an Idiot. Seriously, Seth? Opening the window in the middle of midsummer's eve, while there are a bunch of unholy hellhole unseelie reverse doubleplusungood beasties on the loose?
- The Woobie: Raxtus. Being half-fairy and half-dragon would be bad enough, but he's also a "Well Done, Son!" Guy to his father, the king of the dragons, who makes it very blatant how he feels about his son. Thankfully, he Took a Level in Badass in the fifth book and impressed his father enough that Celebrant took him back to Wyrmroost to be properly trained.
- Write Who You Know: Word of God admits that his real-life little brother is impetuous in the same way Seth is, and while they're not exactly the same person, they're very close.
