Its John’s Birthday, Finch gives him the day off and hands him a key as his gift. Finch does this because he knows that the new number will bring back John’s old memories. Finch decides to deal with the next number on his own with help from Detective Fusco, Karen Garner a lady who is on the run from US Marshall Service for identity thefts. Finch decides to take help of Detective Carter, but she has a news of her own for Finch regarding a kill in New Rochelle relating to John’s past. Carter and FBI agent Donnelly visit New Rochelle to find links related to John.

Finch who is in pursuit of Karen gets help from John. They come to know that Karen is actually Sarah Atkins who is on the run from her husband Brad Jennings of Us Marshall Service, who framed Sarah for his own good. In the same way, John’s ex-girlfriend Jessica Arndt was killed in a fake car accident, when actually her husband Peter Arndt killed her by snapping her neck when she hit her head on a table. Sarah is taken into custody by Jennings and is taken out of the city where his plans to kill her are foiled by John.

Finch asks Carter to look for John because he has lost contact with him. She finds John who is taking Jennings to deal with him,and let’s him drive off with Jennings in the back of the trunk, not knowing what John will do to him. Later, Carter gets John’s old military information and shreds it afterward to avoid Donnelly finding out about everything. She then receives a call from a warden letting her know that Jennings is now serving an imprisonment in Torreón penitentiary in Mexico after “a man in a suit” turned him in.

John is given the address that Finch forgot to give him when he gave him the key. The address leads him to an apartment that Finch has now given him. In the same flashback from the episode earlier on, the man in the wheelchair that John accidentally hit turns out to be Finch who was too late to save Jessica.
