Chapter 25

Will, Tris, and Christina get new tattoos. Tris has the Abnegation symbol inked onto her right shoulder. Afterwards, the trio stand at the railings overlooking the Chasm and throw down stacks of Erudite reports. It is supposed to be a cathartic experience, but Will and Tris get into an argument about Jeanine (the Erudite representative) and her intentions. They also argue about Abnegation's right to rule unilaterally. Eventually, Tris spots Four climbing towards the Pit's glass ceiling and decides to follow him. Aware that Tris is shadowing him, Four asks her to enter his fear landscape with him. He also implies that the experience will reveal his real name and why he is called Four.

During the simulation, Tris notes that Four's first three fears are heights, small spaces, and the act of killing. When a man materializes in front of them, Tris identifies him as Marcus Eaton, a prominent Abnegation leader. Suddenly, Tris realizes that Four is Tobias, Marcus’s son who defected from Abnegation for Dauntless. Determined to protect Four, she jumps in front of him as Marcus attacks Four with a belt. Tris manages to destabilize Marcus, but the simulated figure fights back. Eventually, Four jumps in front of Marcus to protect Tris, and the fear landscape vanishes. Tris is incredulous that Four only has four fears and realizes that this is exactly how Four got his name. Meanwhile, Four tells Tris that he has something else to show her.

Chapter 26

Four and Tris make their way to the bottom of the Chasm. There, Four reveals that he chose Dauntless even though his test results identified him as Abnegation. While his choice allows him to avoid Marcus, Four confesses feeling out of place among the new Dauntless leadership. He also shares his conviction that selflessness and bravery are similar in nature and that one should be free to show aptitude for both, whether in Abnegation or Dauntless.

Meanwhile, Tris confesses that she chose Dauntless because she wasn't selfless enough to remain in Abnegation. Four disagrees with her assessment and reminds her that she stood up for Al during initiation and for him during the fear landscape simulation. When Tris wonders why he pays so much attention to her, Four confesses that he likes her and tells her to call him Tobias. Even though Tris is incredulous that someone of Four's caliber is attracted to her, she is secretly pleased. The two share their first kiss, and Tris imagines that, perhaps, if they had both made different choices, they would be kissing in the gray clothing of Abnegation.

Chapter 27

The next morning, Tris is in a happy mood, and even Will and Christina notice her uncharacteristic cheerfulness. Eventually, Four walks into the cafeteria, and Tris eagerly watches him. He ignores her, however, and her good mood quickly evaporates. Meanwhile, Uriah tells everyone that they will get to experience one of the instructors' landscapes that day. Later, Uriah is proved right when Lauren, the instructor for the Dauntless-born initiates, confirms that everyone will enter her fear landscape to practice for the final test.

She tells the initiates that most of them will see an average of ten to fifteen fears in their landscapes and that the lowest number of fears recorded in recent memory is four. Immediately, Tris realizes that Lauren is referring to Tobias. During her turn in Lauren's fear landscape, Tris experiences a kidnapping that resembles Peter, Drew, and Al’s attack. Despite knowing that she is in a simulation, Tris panics. She screams relentlessly until a voice orders the simulation to stop. When the...
