5. Casus Belli

Complete story — includes the ending

Sekou is publicly identified as a suspect in the bombing and Carrie has to rush to help his family; she leaves Quinn to look after Franny until Latisha, her nanny, arrives. She learns that the recording of Conlin and Saad did not come from her NSA source, but does not know who gave it to her. Carrie is outed as Sekou's defender, which leads to a hostile mob of protesters gathering outside her apartment. When protesters start throwing rocks, an agitated Quinn shoots one of them; he then tells Latisha and Franny to hide in a bathroom. The NYPD surrounds the building and sends in an ESU unit, but Quinn takes an officer hostage, forcing them to abort the operation. Carrie returns home and attempts to talk Quinn down; he claims to have proof she is being spied on. An ESU team storms the apartment and arrests him. Carrie later finds his phone, containing photos of the man across the street, Porteous Belli, and those he took while tailing Belli, and she then sees someone watching her from there.
