* MagnificentBastard: Niccolo di Chimici. Silvia, the Duchessa of Belleza in book one, also qualifies as a female, protagonist version.
* {{Narm}}: Sky's dad's stage name is ''Rainbow Warrior''. And this man is supposed to be an ''American rock star''.
** Maybe he started performing during TheEighties?
** I suspect this is a reference to the Greenpeace Ship [[http://en.wikipedia.org/wiki/Rainbow_Warrior_%281955%29 of the same name]], which was famously bombed by the French Intelligence Service. It caused quite an outrage, and has been referenced by a lot of real musicians.
** He's explicitly stated to have been an '80s star, and considering Sky's probable year of birth, it would have been likely even so. It's still silly by modern standards, admittedly.
* TearJerker: [[spoiler:Lucien's Earth death in the first book - and the funeral - and Rodolfo's visit.]]
** [[spoiler:Luciano's brief reunion with his parents]] in ''City of Secrets''.
* TheWoobie Many members of the cast qualify from time to time, but Guido from the first book deserves mention. He's hired to murder the beloved Duchessa of Belezza, a figure who is practically worshiped by the people as a demigoddess. Why is he committing this act of treason? Because [[IllGirl his father is deathly ill]] and [[TheGamblingAddict his brother]] squandered the family fortunes, so [[ImpoverishedPatrician there's no money for medicine]]. Worse yet, Guido [[spoiler: loses his nerve when confronted with the Duchessa and can't bring himself to kill her;]] he's spotted with the knife, tackled, and thrown into the equivalent of the Doge's dungeons. Ashamed and resolved to his death, he throws himself at [[spoiler: the Duchessa's]] feet and [[ForgivenessRequiresDeath begs her forgiveness before he dies]]. [[spoiler: Silvia spares his life because he's so repentant and apprentices him to two of her former lovers ... after telling them that Guido tried and failed to kill her. [[TheAtoner Guido spends the rest of the books tailing Silvia and being her bodyguard/manservant.]] ]]
** In terms of the main cast ([[DysfunctionJunction all of whom have problems]]), the woobie award goes to Luciano and Nick, hands down.
