Denth’s Speed

Yes, Denth is inhumanly fast. He’s a Returned, after all, and has all of the physical enhancements that come with that. Even when he’s chosen not to manifest most of them, he’s still got an edge, just like Vasher does.

How do they hide that they’re Returned? Well, it comes down to mastery of their ability to change their appearance. They can’t shape-shift entirely; they can just alter some things about their appearance. They can change their weight, their hair color, and things like that at will. Vasher doesn’t do this often, but Denth has been known to use it as a disguise. The problem, after you do this once and someone realizes it, your nature becomes very suspect.

They have learned to suppress their divine Breath. This allows them to hide, but they must be careful never to give away all of their Breath. Denth has been a Drab before—he’s not completely lying—but never for longer than a few days. And his divine Breath is always there, suppressed. So he doesn’t know what it’s like to be a true Drab, which is why in this chapter he says he doesn’t think it changes you that much. He’s never felt it.

Tonk Fah Wants to Be the Mean One

Tonk Fah is a sociopath. He doesn’t feel an emotional connection to other people, nor does he feel their pain when he hurts them. He tortures and kills animals when it strikes his fancy. There’s a dead parrot in the basement of the safe house, which is why Denth keeps Vivenna from going down there. There aren’t any bodies of Idrian soldiers down there currently, though Denth has had a few of them killed already. The fact that he has people watching their house, plus Vivenna’s mention of her father’s soldiers checking Lemex’s house first, are tiny clues. They do indeed go there first, and Denth has his people there watching. That’s how he catches the Idrian soldiers.

By this point in the story, he’s killed about three people who have come looking for Vivenna. The death count will eventually reach several dozen.
