When the number of Sandra , a 911 operator, comes up, Harold goes undercover at the 911 call-center. Later, a child is kidnapped and the call is routed specifically to Sandra. She is ordered to delete an earlier day’s 911 call logs, in return for the child’s life.
In 2010, Harold was working with Dillinger , an ex-Blackwater mercenary who performed the same duties currently performed by Reese. Their current number is Daniel Casey , a hacker who tests computer security systems.
The Machine orders Root on several tasks such as helping a convict escape and using him to impersonate a Department of Defense employee in order to obtain a secret note. Afterward, she and Harold’s team coincidentally reach the same person, a janitor.
The team receives the number of Maria Martinez , an engineer working for the international energy company HydralCorp. Maria is working to clear the name of Omar Risha , a man from Iraq suspected of being a terrorist.
The team witness Leona Wainwright being killed by a suicide bomber. She worked for the government, managing security clearances; Finch deduces from cell phone information that Vigilance killed her. Their next number, prosecutor Matthew Reed , sends Reese and Shaw to a high school reunion in Westchester.
The new number is Congressman Roger McCourt , who serves on the powerful Rules Committee. The team is initially baffled: He has no obvious enemies. They eventually discover a connection to Decima:
The Machine provides Grace’s number as a result, and Reese, Shaw and Root work to protect her while evading Decima, who use Samaritan to spy on them within the range of New York.
