Allegiant

Tobias asks Peter why he didn’t inoculate himself against the memory serum and accuses Peter of following him because Tobias is carrying the memory serum. Peter shoves Tobias, and they fight. Tobias manages to subdue Peter and tells him he’s evil because he always chooses to hurt others. Peter says this is why he wants the memory serum. He is tired of being cruel and wants to start over and be reset. Tobias promises Peter that he’ll be reset so long as he leaves Tobias alone. They then head in the direction of Evelyn.

Tris, Caleb, and Matthew walk down the hall and are worried because Cara should have the lights off by now. Matthew shoots into the ceiling to create a diversion, and Tris and Caleb run to the Weapons Lab. Security guards try to stop them. Tris looks at Caleb and realizes how much she loves him. She tells the guards that Caleb is her prisoner and that she’ll kill him if they move. Tris takes the backpack of explosives Caleb is carrying and tells him she loves him. Caleb says he loves her too. Tris then shoots at the guards and runs, and the guards chase after her.

Tris eventually rounds a corner and sees two guards outside the Weapons Lab. She shoots them both and places the explosives on the doors. Tris then goes to the end of the hall and detonates the explosives. The guards chasing her shoot her in the arm, but she stumbles back to the exploded doors and enters the vestibule between the Weapons Lab and the hallway. Tris knows she will survive the death serum as she enters the Weapons Lab.

Tobias stops in front of Factionless Headquarters and tells Peter how much he hates this place. Tobias walks into the lobby, and someone goes to tell Evelyn he is there. She returns and takes Tobias and Peter to a meeting room where Evelyn is waiting. Peter waits in the hallway, leaving mother and son alone. Tobias tells her the Bureau will reset Chicago and then shows her the vial of memory serum he brought with him. Tobias tells Evelyn she’s no better for destroying the factions than those who fought to keep them. Tobias also tells Evelyn she’s no better than Marcus; she is a tyrant over the city just as he was a tyrant over their home and family. Tobias says he won’t reset her memory, but she must choose between leading the factionless or having her son back. Evelyn hugs Tobias and says she chooses him.

In the vestibule, Tris smells the death serum and sinks to her knees as she fights its effects. She then falls to her side as her will to live battles with the serum’s pull toward death. Tris suddenly feels invincible and pushes herself up. As she shoulders her way into the Weapons Lab, she finds fresh air and David holding a gun.

David asks Tris if she inoculated herself against the death serum, but he doesn’t believe her when she says she didn’t. David explains that he knew something was happening when Tris began hanging around GDs. So, he came to the lab and wasn’t surprised to see her. David explains he has to kill Tris. Tris sees the box with the memory serum sitting on a counter a few feet from her. She tells David that she knows he designed the simulation serum that killed her mother. David becomes angry and says he warned Natalie to get out, but her foolishness and selflessness killed her. Tris lunges toward the box, and David shoots her. She enters the code into the keypad as David shoots her again. Tris hits the green button to release the serum as David shoots her a third time. She falls to the floor, hears the box churn, and sees David slump in his wheelchair. Tris then sees her mother walk toward her and kneel at her side. Natalie tells her daughter she’s done well and that her friends will care for each other. Tris closes her eyes and dies.
