Badass Decay: It’s hard to imagine the Jonathan of this book hunting his foe across Europe with a Kukri blade.
Evil Is Sexy: The Count uses supernatural ‘animal magnetism’ against Mina, and Elena eventually does something similar with Jonathan. Beherit is described as beautiful and André Kovacs seems to love him, although Mina finds his particular brand of beauty repulsive. The only non-sexy vampire out there is Kovacs, who is also the least evil.
Villain Decay: Dracula goes through some rapid decay in the last chapter, presumably to hammer home how much worse Beherit is.
