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.
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.
This year is San Antonio’s 300th anniversary, and the city is marking the occasion with events, activities, and new infrastructure. Ahead of the festivities, there’s been a flurry of development: In the past few months, the botanical gardens completed an expansion; the city’s first food hall, the Bottling Department, debuted at the Pearl; and San Antonio’s iconic passenger barges got an upgrade, with colorful electric models replacing the old gas-fueled boats. In January, the city will unveil Confluence Park, an expanse of trails and science-focused education facilities near the convergence of San Pedro Creek and the San Antonio River. A commemorative week is planned for early May, with celebrations at each of San Antonio’s five missions and the dedication of San Pedro Creek Culture Park, a once-unremarkable drainage ditch that’s been transformed into a waterfront promenade with public art and performance spaces. Ruby City, a new David Adjaye–designed art center that will house more than 800 pieces from the Linda Pace Foundation Collection, is expected to be completed at the end of 2018. And boutique stays still in the works — including a Thompson Hotel and the third location of the Saint Hotel — hint that San Antonio’s heyday is just beginning. —Devorah Lev-Tov
Three high-ranking Travelers are sent back by the Director to put Grace on trial for violating protocols, overwriting a person who was not assigned to be her host, and sabotaging the Grand Plan. Mac and the team must give testimony at the trial that will determine if she should be overwritten or not. Meanwhile, the Faction is trying to replenish its numbers by overwriting people with the stored minds in the Quantum Frame. It transpires the trial was staged by the Director to flush out a Faction member from within the three Travelers judging Grace, which it successfully does, this leading to Mac's team securing the Quantum Frame.
