In Chap­ter Forty of *Alle­giant*, Tobias secures Amar’s help to re-enter the city, plan­ning to meet with Christi­na, Peter, and George to arrange trans­porta­tion. Mean­while, Tobias grap­ples with guilt over Uri­ah’s fate, rehears­ing apolo­gies to Zeke in his mind. His inter­nal tur­moil man­i­fests phys­i­cal­ly as he throws a pil­low in frus­tra­tion, star­tling Cara. Their con­ver­sa­tion shifts to for­give­ness, with Cara shar­ing her com­plex feel­ings about Tris’s role in her broth­er’s death, empha­siz­ing the impor­tance of con­fes­sion over excus­es.

Tobias press­es Cara for advice on seek­ing for­give­ness, draw­ing par­al­lels to his own guilt about Uri­ah. Cara sug­gests that a sin­cere confession—without justification—is cru­cial, fol­lowed by giv­ing Zeke space. She chal­lenges Tobias to sep­a­rate grief from guilt, remind­ing him he did­n’t direct­ly cause Uri­ah’s injuries. Despite her com­fort­ing words, Tobias strug­gles to inter­nal­ize her per­spec­tive, high­light­ing his emo­tion­al con­flict and self-blame.

The group recon­venes for din­ner, where Amar dis­trib­utes syringes con­tain­ing an inoc­u­la­tion against a mem­o­ry-eras­ing serum. While most com­ply, Peter deceit­ful­ly avoids inject­ing him­self, rais­ing ques­tions about his motives. Tobias reflects on the irony of will­ing­ly for­get­ting one’s past, hint­ing at deep­er themes of iden­ti­ty and choice. The scene under­scores the group’s pre­car­i­ous mis­sion and the moral ambi­gu­i­ties they face.

Lat­er, Christi­na con­fronts Tobias about their secret plan to stop the Bureau’s mem­o­ry reset, express­ing con­cerns about the ongo­ing chaos in the city. Tobias admits Amar is unaware, pri­or­i­tiz­ing loy­al­ty to their cause over Bureau alle­giance. The chap­ter ends on a tense note, with Christi­na warn­ing of the poten­tial consequences—violence between factions—if their inter­ven­tion fails. This sets the stage for the loom­ing con­flict between per­son­al duty and broad­er con­se­quences.
