Philip is ordered by the Director to attend an "update" with various other Historians, which is where the altered timeline's history is imprinted onto their minds, but it comes with physical and emotional consequences. Trevor tries to help a former football teammate with past trauma. Hall returns from prison and has a new mission assigned to him from the Director. Kat has complications with the pregnancy.
Vincent asks the team to stand down and let him finish what he has been planning. When the team refuses to comply, Vincent holds the lives of Kat, David, Jeffery, Ray, and Grace over them, and forces them to reveal themselves as Travelers to the world. The team must make the choice between breaking protocol and thus risking being overwritten by the Director, or doing what they must to save the ones they've grown to care about since their arrival in the 21st.
In August 2012, Travelers sued the National Football League for forcing the company and its subsidiaries to pay to defend the league for failing to protect players from brain injury, in a case filed in the New York State Supreme Court called Discover Property & Casualty Co. et al. vs. National Football League et al., New York State Supreme Court, New York County, No. 652933/2012. The league had sued over three dozen insurance companies the week before in an attempt to cover the claims that players made against the league.
MacLaren and Forbes stake out a criminal transaction that becomes a shootout. MacLaren's team is directed to assist an older traveler team: the incident's survivors, whose leader, Rick Hall, reveals that the deal was the assigned transfer of a device with a Russian traveler team. MacLaren is shocked by the violence between teams and by Hall's jadedness. Hall's teammates, Carter and Luca, are both dying, but Marcy saves Luca by transfusing Carter's blood; Marcy suspects Luca is her brother due to his suffering from night terrors. Hall demands that he become the leader of a merged team, and demands MacLaren kill Forbes to prevent their exposure. MacLaren and Forbes arrest Hall and Luca, and the team transfers the device. Trevor quits football to focus on his grades, but is grounded. Ray demands more gambling information from Philip. Carly rebukes Jeff, who harasses Marcy. Carly and MacLaren sleep together.
Many of Travelers' ancestor companies, such as St. Paul and USF&G, are technically still around today, and still write policies and accept claims in their own names (under the overarching Travelers brand name). As is typical of most insurers in the United States, Travelers never dissolved the various companies it acquired, but simply made them wholly owned subsidiaries and trained its employees to act on behalf of those subsidiaries. This is a common risk management strategy used by U.S. insurance groups. If any one company in the group gets hit with too many claims, the situation can be easily contained to that one company (which is placed in runoff and allowed to run its policies to completion), while the remainder of the group continues to operate normally.
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.
The team learns that Traveler 001 is still alive in the body of his former psychologist, Perrow, when the Faction tries to capture him/her. Perrow dies but they believe 001 had access to a transfer device (since in the future he helped construct one) and as a result they are unsure where his consciousness now resides. Doubts about their loved ones worsen for Kat (suffering hallucinations and suspicions), Jeff (now, not Jeff and trying to make amends) and David, who is concussed.
