There are a plethora of mastermind sidekick combos like Finch (Michael Emerson) and Reese (Jim Caviezel) on "Person of Interest," but none quite the same. Many of them come in comic book form, such as Batman and Robin. But Finch isn't quite a superhero. He's just really intelligent. There are some other mastermind sidekicks that are just as unique as Finch and Reese. Here's how some of the others stack up against Finch and Reese.
Bones and Booth: "Bones"
Although Bones (Emily Deschanel) and Booth (David Boreanaz) are now in a relationship, Bones has always been the mastermind in the relationship. She's much more intelligent than Booth, although Booth understands people much better. She also tends to be bossy with him, and he is usually fine with that.
The main difference between the Bones-Booth relationship, and the Finch-Reese relationship is that Bones and Booth have a child together. Other than the occasional temporary person-of-interest baby, such as the one on the episode "Baby Blue" (complete with a hilarious domestic dispute between Finch and Reese), Finch and Reese probably won't be having a baby together.
Six and Baltar: "Battlestar Galactica"
There were two versions of Six (Tricia Helfer), and they were both in charge. One of them was a hallucination caused by an external force, and the other was a flesh-and-blood Cylon. Both versions of Six were masterminds with complete control over Baltar (James Callis) through his need for power, total subservience to his physical desires, and her ability to completely fulfill those desires.
Besides the fact that Finch and Reese won't be winding up in bed together, the main difference between them and the Six-Baltar combo is that Reese is competent on his own. He has his own strengths and is also intelligent enough to make do without Finch telling him what to do.
Doctor and companion: "Doctor Who"
The unique thing about the Doctor and each of his companions is that the companion keeps the Doctor from going too far. Although the Doctor has great power and acts as the mastermind in the relationship, the companion ensures that he does not use his full powers to "right wrongs," which could have horrible unintended consequences.
The Finch-Reese relationship is the opposite of the Doctor-companion relationship when it comes to limiting power. Finch is the mastermind, but tends to be the conservative one. Reese is the one who is sometimes willing to go too far, and both Finch and Carter (Taraji P. Henson) sometimes have to set him straight.
Sherlock and Dr. Watson: "Sherlock" (or any other variation)
The Sherlock and Dr. Watson relationship is one of the best known in history. It is also the most similar to the Finch and Reese relationship. The one main difference is that John Reese can solve crimes on his own and is actually just as popular as Finch with the fans.
Although Finch is the computer genius who created the Machine and tells Reese who to look for, Reese is smart enough to do much of the work without Finch's help. He also has great physical capabilities with the ability to fight off bad guys, which is something Finch is incapable of doing with his apparently permanent injuries. Once Reese is sent out to do the job, he usually only needs Finch in extreme situations, such as in the Season 1 finale, "Firewall", and for retrieving additional information on a person through camera-spying.
