Come to think of it, Claire Stanfield (the Rail Tracer) embodies both the human world and the monster world. As a matter of fact, with his attitude and acrobatic prowess (and a disguise), Claire could practically pass himself off as a vampire. Just so long as nobody asks him to change into a bat.
Last, I just noticed that Mavis is so different yet so alike to Chane. Both are brunettes who know so little about the world beyond thier families (albiet Chane is more stoic on that subject). They have a father who has lived for a long time, only while Mavis is just as "immortal" as Dracula, Chane doesn't have the luxury of sharing her dad's immortality. Plus, as a father, Dracula is everything Huey Lavoret isn't.
