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 Director can invoke three other protocols in special situations: Protocol Alpha temporarily suspends all other protocols when a critical mission must be completed at all costs, Protocol Epsilon can be invoked when Traveler archives are threatened, and Protocol Omega permanently suspends all other protocols when the Director abandons the Travelers because the future has either been fixed or deemed impossible to fix.
It's not a special-effects-heavy show. Instead, it focuses on squeezing every drop of juice out of the slightly off-kilter premise. For a start, "taking over" present-day human hosts kills them. So there's a massive built-in moral dilemma. And it's worked out with painstaking logic. Time travelers try to pick people who were about to die anyway - but this too presents problems. The time travelers need to remain undiscovered, which means seamlessly picking up the threads of their hosts' lives. Time travelers may have motivations of their own, which need to be dealt with in the present. It all meshes beautifully.
Resuming their hosts' lives, the team suffer paranoia and hallucinations of their future pre-Travel lives, side effects of the antitoxin. MacLaren's coworkers hold a surprise party for his 15th anniversary with the FBI. Kat confronts him about lying to Forbes; he seduces her, but she is still certain he is cheating. During their lovemaking, MacLaren hallucinates that Kat is a woman with very short hair, with Carly's number (3465) tattooed on her neck. After Rene attempts to shoplift some clothes with Trevor and another friend, Trevor confronts the two outside, in an alley. During a fight between Trevor and the other guy, Trevor possibly experiences a slippage of time, where his friend is able to connect with a punch. This will later develop into Trevor's diagnosis of temporal aphasia. Their intimacy growing, David reluctantly helps Marcy perform surgery on herself to prevent seizures. Carly rebuffs a representative of Child Protective Services. Trevor reins in his host's delinquency, and he and Renee meditate. Ray takes Philip to a twelve-step meeting for drug addicts and gets him a pet turtle to care for. Trevor and Philip learn the team has a new mission.
Saint Paul Fire and Marine Insurance Co. was founded March 5, 1853, in St. Paul, Minnesota, serving local customers who were having a difficult time getting claim payments in a timely manner from insurance companies on the east coast of the United States. It barely survived the Panic of 1857 by dramatically paring down its operations and later reorganizing itself into a stock company (as opposed to a mutual company). It soon spread its operations across the country. In 1998 it acquired USF&G, known formerly as United States Fidelity and Guaranty Company, an insurance company based in Baltimore, Maryland, for $3.9 billion in stock and assumed debt. By buying USF&G, they went from the 13th to the eighth largest property and casualty insurance company in the United States. Through economies of scale between the two companies, and a difficult business environment, they downsized the company substantially over the coming years by selling certain business units to focus on more profitable business units.
The first season of Travelers has a score of 100% on Rotten Tomatoes based on nine reviews with an average rating of 8.0/10. Neil Genzlinger, writing for The New York Times, described the first season as "tasty", and "enjoyable science fiction", with "some attention-grabbing flourishes and fine acting". Hanh Nguyen, writing for IndieWire, describes the series as "fun and freaky," finding the series' appeal "in how the core group of five travelers adjust to life in our present," noting the "human nature in the travelers". Lawrence Devoe, of TheaterByte.com, called the series "tautly paced and suspenseful" with "well-developed characters", declaring that "Brad Wright has a real knack for creating futuristic series". Evan Narcisse, reviewing the first five episodes for io9, appreciated the moral dilemmas offered by the series premise and the awkwardness presented by the characters' interactions with their hosts' friends, colleagues, lovers, or caretakers: "This is a superhero show in double disguise, offering up clever explorations of the secret identity concept that touch on the guilt and contortions that come with living a double life." Netflix announced that the series was one of its "most devoured" series in 2017.
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.
