way, Gerry notices zombies ignoring an old man and an emaciated boy. When one of the escorts, identifying herself only as "Segen", is bitten on the hand, Gerry quickly amputates the appendage, preventing further infection, and the pair are able to make it out of the city aboard a commercial airliner. Musing on what he saw in Jerusalem, Gerry calls Thierry, and has him divert the plane to a World Health Organization medical research facility in Cardiff. On approach, a stowaway zombie is discovered, and the majority of passengers and the flight attendants are quickly infected. Gerry sets off a grenade to rupture the cabin and eject the zombies, but it also results in a crash landing. Gerry and Segen survive the crash and make their way to the Cardiff facility where he faints from his injuries. Three days later, Gerry awakens and explains a theory – that the zombies ignore terminally ill or severely injured people as they are unsuitable hosts for the infection – to WHO employees. He suggests injecting themselves with a deadly pathogen to act as a "camouflage" against the zombies. However, the scientists point out their pathogens are located in a zombie infested portion of the facility. Gerry, Segen, and the head doctor battle their way through the lab, where Gerry finds himself in the room with the pathogen samples. Before he can leave, a lone zombie appears behind the door and blocks Gerry’s only means of escape; forcing him to inject himself with one of the pathogens to test his theory. When Gerry opens the door, his theory is proven correct; the zombie ignores him, allowing him to walk with the pathogen samples and safely bypass the rest of the zombies in the lab. Gerry and Segen arrive at a safe zone in Freeport, Nova Scotia, where he is reunited with his family and Tommy. A vaccine is then developed which acts as a camouflage against the zombies, allowing survivors to safely escape zombie-infested areas, and even mount offensives against them, but the war goes on.
