Titch’s sketch introduces art into Wash’s life. Like science, art represents a way to better capture and understand the world. In addition, Titch continues to try to get Wash to view them as equals, but the book also illustrates how this is nearly impossible due to their difference in power and status. Even though he tries not to acknowledge it, Titch has control over Wash’s life, and this makes it difficult for Titch not to inherently think of Wash as a lesser person meant to cater to Titch’s needs.
