To prevent an explosion that kills thousands, the team steals antimatter from a military convoy. The material's intended recipient is a new traveler who fails to prevent his host's suicide, forcing the team to improvise. After failing to upgrade their containment device, the team returns the antimatter to its origin facility. They form a tenuous alliance with Dr. Delaney, who produced the antimatter; history records her as complicit in the weaponization of antimatter, but she actually opposes Major Gleason's ambitions. MacLaren informs Delaney that they will return soon. Philip retains his host's heroin addiction. MacLaren meets his wife, Kat, but also resumes a preexisting relationship with Carly. Marcy works to build trust with a confused David.
The Faction sets off nuclear blasts that destroy all of the Travelers' archives outside the US. David, left for dead by the Faction in the last surviving archive, is the only person who can disarm the nuclear device. He succeeds but is exposed to lethal radiation. Kat's suspicions about MacLaren, temporarily allayed, surge again and she throws him out – for her the marriage is over as she feels he is no longer the man she first met. Jeff tries to escape from interrogation by 001; he is eventually found having been walled up. Marcy hopes the Director will send a Traveler medical team to save David but no help arrives. In the moment before he dies, David conveys a message from the Director: "Protocol Omega."
The joy is to watch how these islands are transformed by changing distances, by sunlight, by clouds. On some, there is a sliver of beach, just enough from which to swim; others are edged with little villages built on boards, the houses tied together. All are tropical paradises: Koh Phi Phi, Koh He, Koh Racha, Koh Surin, Koh Dok Mai, to name some of the favorites. Koh Phuket serves as a good jumping-off point. After being devastated by the 2004 tsunami, these islands have made a comeback.
