After asking Marcy to move out, David admits he cannot bear to be without her. She tells him she is dying, and they kiss. Trevor tries to connect with his father. Jeff files assault charges, preventing Carly from finding a job. She asks him to take the baby for an afternoon, unaware he has tipped Kat off to Carly’s relationship with MacLaren. Under orders, a traveler murders her host’s Cabinet-member husband, and instructs MacLaren to board a flight as Congressman Bishop’s seatmate. In flight, MacLaren learns he is to activate a stasis field to save himself and Bishop, while all others aboard will die in a crash. MacLaren discovers Kat followed him on board, believing she would witness his infidelity. He instructs Kat and Bishop to use the stasis device, and attempts to survive impact unaided, using only Philip’s knowledge of the crash. At the crash site, the team resuscitate Kat and Bishop, and Bishop is overwritten. To Carly’s dismay, MacLaren is taken away by traveler paramedics before the team can reach him.
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.
