In the simulation, Beatrice is first made to choose between the cheese and knife, which she questions and refuses. After two more events, she wakes up to see a baffled Tori Wu, saying her results were inconclusive, only having ruled out two factions (Amity and Candor); her choices in the simulation showed equal instances of Abnegation, Dauntless, and Erudite. Tori tells Beatrice that she will delete the computer records upon telling her that she is Divergent, and warns her not to tell anyone, not even her family.
Beatrice later encounters a Factionless man who asks for food and later cryptically tells her to "choose wisely" at the Choosing Ceremony. She arrives with her family at the ceremony anxious about her choice. Her father is counting on her and her brother to choose Abnegation. During the ceremony, Beatrice is deeply surprised by the fact that her brother Caleb chose Erudite, the faction of knowledge instead of Abnegation, the faction of the selfless. When it's her turn, her choice not only surprised her family but herself, by choosing to spill her blood on hot coals or rocks, therefore, choosing Dauntless. Before they leave, Beatrice takes one last glance at her family; she sees her mother smiling at her, her father staring at her with a look of accusation, and her brother already happily adjusting with his new faction. Upon seeing Caleb, she realizes that she must, and eventually will, adjust, as well.
As the Dauntless run towards the train station, her confusion dissipates and is replaced by exhilaration. Here, she meets Christina, a transfer from Candor, when Beatrice jumps on the train. When they arrive at their destination, they must jump off the train onto the roof which is at least seven stories below. At the point when everyone has jumped off, Beatrice asks Christina if they should jump off together, which Christina accept.
