In this chapter, we learn that the incision made in the bone is clean, and that it is not possible to do it with typical equipment. We also learn that this is the same set of bones that belonged to the Bai family. This is the first time we've heard of this family, so we're not sure what to make of it. We're also told that the tattoo on the back of the bone was only a few days old, so it hasn't yet made its way to the top levels of the government. This makes us wonder what the heck is going on with the "bai" in his last name. We learn that his brother, Zian, is also a member of the same family, and the last name of Zian's father is also bai.
