Cary Agos (Matt Czuchry) from "The Good Wife" is a lawyer who spent Season 1 of the show vying for a permanent position at the firm Lockhart & Gardner against the show's star, Alicia Florrick (Julianna Margulies).
Cary, a Harvard grad and 2008 member of the Innocence Project, quickly showed that not only was he willing to resort to underhanded tricks in order to win the position, he enjoyed it. Cary moved through his days at the firm with an almost cheerful, smarmy air. He was quick to cause problems for Alicia. He interacted with her with a sneer on his face and comments that were more often snide than not.
At the end of Season 1, Alicia was forced to resort to pulling a trick of her own in order to secure her position at Lockhart & Gardner. When she won the job, Cary was furious and vowed to seek revenge. What is interesting about his character is that Cary does not seem to acknowledge even to himself the he is equally as guilty of playing dirty - his entire focus was on the fact that he did not win.
Despite the fact that Cary Agos is a secondary character, he makes his presence known. As he progressed through the show's first season, he operated on a tit-for-tat basis with his peers. He does nothing for nothing and was quick to leech onto any opportunity to further his career. After his loss to Alicia, he went to work for the State's Attorney's Office. His boss at that office is Glenn Childs (Titus Welliver), the man seeking to destroy Alicia's husband Peter (Chris Noth).
While Cary's threat at the end of Season 1 seemed genuine, his character in Season 2 seems more amused than threatening. The fact that members of Lockhart & Gardner have needed to come to him for assistance seems to have gone a long way towards assuaging a portion of his self-righteous anger. While he has provided help on more than one occasion, Cary quite obviously gets off on the fact that his former colleagues are sometimes dependent upon him for something, a fact that his new position makes possible.
Cary remains somewhat of an enigma halfway through the second season of "The Good Wife". His character's behavior is often contradictory. He cannot be trusted; his arrogance and enjoyment of feelings of superiority when Alicia needs his help is always present, but he simultaneously is steadfast in his belief in and determination to find justice for the clients. What remains to be seen is whether Cary's seemingly nicer character is real or a charade that will come back to bite Lockhart & Gardner.
"You like to think you're a good person. Maybe that used to be the case. But we both know you'll do whatever it takes."
"Look, here's an idea: come back to the state's attorney's office. Start putting these wife-killers onto death row, instead of getting them off. As good as you are at getting people off."
