In this chapter, we learn that the "heart" of a serpent is "below its head" and "next to its vital part" . In other words, if you attack the heart of the serpent, even though you're a member of the clan, you haven't done anything wrong. Now that the serpent has been tamed, he'll tell the emperor everything about himself. He'll also show the emperor his past, so he can figure out who he really is.
