In "Legacy," the latest episode of "Person of Interest," the theme turns toward complexity. One of the complications is physical and temporary, but most of them unfold from untold secrets. All of the characters are now keeping secrets, but are also suspicious of the other characters.
Reese is still injured
Reese (Jim Caviezel) still has a gunshot wound, and is not quite as capable of beating down the bad guys as he used to be. Losing a fight is more common for him, at this point, and he loses time when he has to sit and recover rather than shaking it off. The injury may not last much longer, but it may be a good thing. Reese is almost too good in a fight, and the injury keeps things interesting. A new injury or worthy foe may be in order.
Detective Lionel Fusco and Detective Carter don't know about each other
Reese and Finch (Michael Emerson) sent Detective Fusco (Kevin Chapman) to spy on Detective Carter (Taraji P. Henson), but now Carter is also working for Reese and Finch. Reese and Finch decide to keep the two detective's secrets from each other, to avoid other complications that could arise from learning the truth, but the secrecy breeds its own complications.
Now that Carter is busy with secret phone conversations with Reese, Fusco begins to get nervous that Carter is planning another attack against Reese. The distrust allows room for some comedy relief, when phone calls Reese receives from Carter about a secret case are interrupted by Fusco, worried about those same phone calls.
The relationship between Fusco and Carter could lead to many new comedic situations in future episodes. Secrecy and lying are the underlying basis of many great sitcoms, and Fusco and Carter could could have a bright future that includes many sitcom-like situations. Reese is also amused by their antics, probably enjoying the idea of playing puppet master. He seems to enjoy pulling the strings, but he also darkens the sitcom atmosphere.
Finch is keeping some new secrets from Reese
Reese has always been curious about Finch, but his curiosity peaks when he spies Finch meeting with a young man who calls Finch "uncle." Things are about to get even more complicated since Reese has sent Detective Fusco to spy on Finch. Will Finch see this as a betrayal if and when he finds out? Perhaps he has already figured it out, but we viewers do not know it yet. Finch has just begun to open up to Reese, and now Reese is repaying that trust by spying. Things could get ugly between them.
