After Carter’s death Reese heads over to his father’s old watering hole in Colorado. Fusco tracks him down to try to talk him to coming back. Finch is reluctant in accepting new numbers from the machine after it failed to warn them of Carter’s death on time. But after reluctantly getting information on the new number, he realized that it belongs to his old colleague in MIT Arthur Claypool. He learns that Arthur has brain tumors and has been having memory lapse. He is guarded by government agents trying to keep information going to the wrong hands about a machine called Samaritan that he created which is similar to what Harold created.

Fusco is still trying to convince Reese to return to New York. Reese was persistent and was not willing to come with Finch. They started fighting and moments later they were arrested by the police.

With the help of only Shaw he tracks down Claypool and save him and his wife from a group called vigilance who intends to use the machine for their benefit. Later Claypool informs Harold that his wife has been dead for two years. The person posing as his wife is “Control”. She is Shaw’s former boss. 

After the winning the war against HR everyone thought that they would easier for Reese and the gang to do their work. But the threat from the Government and Vigilance is much alive. Reese still has not come to terms with Carter’s death. He is blaming the machine for not warning them in time. Now that the government has identified Finch, it would be a difficult for him to operate.
