The Willis (or Sears) Tower, one of several landmarks Roth describes within post-apocalyptic Chicago, the novel's setting.
Initiation into Dauntless is composed of three stages. The first involves learning how to handle guns and knives and hand-to-hand combat with other initiates. Tris lacks the physical strength of most of her fellow initiates, but finishes in sixth place by beating the higher-ranked Molly. When the rankings are announced, a jealous Peter, who finished second, stabs first-place finisher Edward in the eye with a butter knife during the night.
