In Chap­ter Twen­ty of *Alle­giant*, Tobias meets Nita, who leads him through an under­ground tun­nel in the Bureau’s facil­i­ty. The dim­ly lit pas­sage, adorned with shift­ing col­ored lights, reveals a stark divi­sion between the genet­i­cal­ly dam­aged (GDs) and the genet­i­cal­ly pure (GPs). Nita explains that GDs, like her­self, are rel­e­gat­ed to sup­port roles, while GPs hold posi­tions of pow­er. Tobias ques­tions the fair­ness of this sys­tem, draw­ing par­al­lels to the fac­tion­less hier­ar­chy he once knew. The con­ver­sa­tion high­lights his grow­ing frus­tra­tion with the Bureau’s rigid genet­ic deter­min­ism and its impact on soci­etal roles.

Nita shares her tat­too of bro­ken glass, sym­bol­iz­ing damage—a bit­ter joke about her genet­ic sta­tus. This res­onates with Tobias, who grap­ples with his own genet­ic test results and the lim­i­ta­tions imposed on him. Their dia­logue under­scores the ten­sion between genet­ic des­tiny and per­son­al agency. Nita attempts to reas­sure Tobias by stat­ing that even GPs have lim­i­ta­tions, but he rejects this notion, argu­ing that the sys­tem is about more than just genes. His anger sim­mers as he con­fronts the injus­tice of being defined by his DNA, a theme cen­tral to the chap­ter.

The pair even­tu­al­ly arrive at a vibrant under­ground bar, filled with music and chat­ter. The atmos­phere shifts abrupt­ly when a man announces a ver­dict, prompt­ing a rush of peo­ple to leave. Nita spec­u­lates it’s about Mar­cus, Tobi­as’s abu­sive father. Tobias sprints back through the tun­nel, torn between con­flict­ing emotions—whether he desires Mar­cus’s pun­ish­ment or mer­cy remains unclear. His inter­nal strug­gle reflects the broad­er theme of moral ambi­gu­i­ty, as he wres­tles with the dual­i­ty of his par­ents’ actions and their per­ceived masks of virtue or cru­el­ty.

The chap­ter ends with Tobias run­ning toward the con­trol room, dri­ven by a mix of urgency and unre­solved emo­tions. His phys­i­cal sprint mir­rors his psy­cho­log­i­cal tur­moil, caught between his past trau­ma and the Bureau’s oppres­sive struc­tures. The nar­ra­tive leaves read­ers ques­tion­ing whether Tobias will con­front Mar­cus or Eve­lyn, and how his actions will align with his evolv­ing under­stand­ing of iden­ti­ty and free­dom. The chap­ter effec­tive­ly blends per­son­al con­flict with broad­er soci­etal cri­tique, set­ting the stage for future con­fronta­tions.
