Here, Kaz demonstrates that he understands people aren’t motivated solely by money. Matthias, he seems to instinctively know, wants to return to Fjerda and to his old life as a drüskelle. And interestingly, Kaz seems fully willing to facilitate that happening for Matthias, despite what seems like Kaz’s belief that Grisha shouldn’t be hunted and killed. Again, then, the novel highlights how Kaz works only for himself, and anything he does for others is simply also convenient for him.
