The series revolves around a computer program for the federal government known as "The Machine" that is capable of collating all sources of information to predict terrorist acts and to identify people planning them.
According to Nielsen Media Research, the episode was seen by an estimated 6.36 million household viewers and gained a 1.0/3 ratings share among adults aged 18–49.
Reese (Jim Caviezel) and Fusco (Kevin Chapman) are the only ones who attend Root's funeral and set out to find Shaw (Sarah Shahi) and Finch (Michael Emerson).
In Kentucky, Finch is revealed to be on a road trip with the Machine (Amy Acker) to an unknown destination, still grieving over Root's death.
Shaw and Reese find a bomb hidden in a brick and hide it so it can't injure anyone, and alert the President to leave.
Broadcast signals are then hacked by the terrorists, who warn that they'll kill the President tomorrow if his surveillance system program isn't cancelled.
In San Antonio, Texas, Finch arrives at a highly secured government facility with a weaponized virus capable of destroying Samaritan.
Back in Washington, Joey takes Reese to his partners: Logan Pierce and Harper Rose (Annie Ilonzeh).
In its original American broadcast, "Synecdoche" was seen by an estimated 6.36 million household viewers and gained a 1.0/3 ratings share among adults aged 18–49, according to Nielsen Media Research.
As someone who, in the past, has occasionally sided with Samaritan tactics, and has since had her brain scrambled by the thing, she was in dire need of a reset following last week's huge loss.
And on the scale of things in the episode that aren't ultimately heartbreaking, it's always great to see Fusco remind the audience just how competent he actually is at his job and as a member of the team.
