The Hollows/YMMV

• Designated Villain: Lee and Piscary, though Lee seems to have retired from this role.
• Draco in Leather Pants: Kisten, Trent, and Nick.
• Estrogen Brigade: Several characters have these most notably Trent and Kisten even after Kisten died.
• Evil Is Sexy: Arguably, Trent.
• Fan-Preferred Couple: Several. Rachel/Ivy is a favorite but Rachel/Kisten and Rachel/Trent are also common pairings. Less common but present are Rachel/Jenks and Rachel/Al pairings.
• Fetish Fuel: Rachel bites Kisten with "caps", fake vampire teeth, to make the sex kinkier. Rachel is also passionately fond of high-heeled boots.
• Internet Backdraft: The revelation that 'Kim Harrison' is a pen name for Dawn Cook has created an odd amount of backlash among some fans on various forums. Whether or not this is large enough to create a Broken Base has yet to be seen
• Magnificent Bastard: Al
• Moral Event Horizon: Many for the villains including Piscary's off-screen rape of Ivy and Lee allowing several innocent people to die in an explosion on his boat. For some fans Trent's murder of Brett also evokes this trope. Kisten originally setting the bomb on Lee's boat to begin with seems to have avoided this because to most fans Beauty Means Goodness.
• Nightmare Fuel: The infamous 'van scene' may be this to some, Fetish Fuel for others
• Squick: A few examples in the series including the fact werewolves are the result of demons in wolf form raping human women in the middle ages and Ivy's play by play of her own rape
  • Al's insights into the jaded excess of demons is a generator of squicky concepts even though most of it is Offstage Villainy.
• Unfortunate Implications: Ivy is the bisexual monster who, if she ever hooks up with straight-girl Rachel, will probably bind her to sexual and blood slavery.
