With Nairobi held hostage, Gandia negotiates with the crew. The Professor desperately seeks a new plan to save his team.
In flashbacks, Nairobi asks the Professor to be the father of her child by in vitro fertilisation because she believes the Professor to have good genes. Initially opposed to the idea, the Professor agrees. In the present, although the panic room is not present on the bank's blueprints, the Professor deduces the location of the panic room to be in the vicinity of the governor's office—behind the governor's bathroom.
The Professor tells Palermo this. Tamayo and Suárez plan an assault on the bank. Meanwhile, the Professor sends Marseille to Algeria, where the police tortured Rio, to gather intel. Gandía unties Nairobi and uses her to escape while the group holds him at gunpoint. As he escapes, he shoots Nairobi in the head, killing her instantly—Denver throws a grenade, which injures Gandía.
