Travelers was founded in 1864 in Hartford. It was founded to provide travel insurance to railroad travelers at a time when travel was far more risky and dangerous than today, hence the name. Along the way it had many industry firsts, including the first automobile policy, the first commercial airline policy, and the first policy for space travel. In 1954 it established the world's first privately owned weather research facility, the Travelers Weather Research Center, the first organization to make weather predictions using probabilities ("20% chance of rain"). By the early 1990s, Travelers was predominantly a general property and casualty insurer that also happened to do some travel insurance on the side, and it quietly exited its original business in 1994. What was left of Travelers' travel insurance business was acquired by three former employees and is now known as Travel Insured International, a Crum and Forster Company.
Marcy erases Kat's memory of the crash and of the preceding day, and stages her home to make it appear as if she had drunk too much the night before. Philip removes MacLaren's car from the airport, but Forbes believes it is theft. Carly extracts Philip, while Forbes and Kat search for MacLaren. An advanced traveler medical team treats MacLaren with nanites to repair his massive internal damage. Trevor undergoes a painful procedure to grow a transplant heart for MacLaren. Unconscious, MacLaren experiences memories of his host's life with Kat. He discovers that they were deeply in love, and that she very much wanted to have children. She did not because MacLaren feared losing Kat after she suffered a life-threatening miscarriage. He also sees that they began to grow apart due to MacLaren's work commitments. MacLaren recovers in time to stage a cover story for Forbes, claiming that Philip is MacLaren's confidential informant and went rogue to prove that MacLaren's life is insecure. MacLaren returns home, and tries to apologize to Kat, but she avoids him.

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.
