In this chapter, Tommo explains that he is made of a substance called "talent" and that he must be made of "simple mud and pebbles" if he is to be made into a diamond. He explains that when the pebbles are accumulated, they form a "boulder" and then a "great series of mountains" that will crush even the "mightiest diamond" . Tommo says that he has no new friends, and that his sister is probably at least 60 percent of his power. He says that the deep for "smirk diamonds" are born hundreds of miles under the surface and that under the pressures of the sea, they will crush him into "bits in an instant". He says this is why they call him "im that . . he is the "most uncontrollable of all ". He adds that he can't move because of the "blood" in his veins. He shows the reader the use of thalassotherapy, a natural healing technique based on the Greek word "thalassa", which means "sea" in Greek. The treatment involves administering various minerals orally to the body and increasing the body's circulation with seawater. It is believed that this treatment increases blood flow, which in turn strengthens the body. The human body contains roughly the same amount of salt as seawater.
