Finch has gone into hiding since he was unwilling to kill to protect himself and the team solely to prevent Samaritan from being activated, which Decima has now been able to do in a beta test. They all know that the team is the first on Decima's hit list, with Finch at the top of that list. Decima's task is made all the more easy by Samaritan, which, in its current state, has capabilities equal to the Machine. However, Samaritan will only get more sophisticated as it learns from what it sees. Even though Finch is no longer around, Reese still believes they should assist whoever the Machine identifies as a target or perpetrator of a violent crime, even at the risk of their own lives now that they have to avoid any camera in the five boroughs. That next person is Grace Hendricks, Finch's ex-fiancée, who Greer believes is the only person who can help him get to Finch, if only in a trade. The questions become whether Reese, Shaw and Root can protect Grace from Decima while protecting themselves, whether they can continue to hide from Grace the reason why she needs to be protected specifically not divulging that Finch has been alive all these years, whether they can find Finch, and if it comes to a choice whether Grace or Finch will be sacrificed if they indeed can find him.
