Geoff Stults is
Major Walter Sherman,
U.S. Army (retired). Due to a
traumatic brain injury suffered in the
Iraq War due to a
roadside bomb explosion that only he survived, Walter is
paranoid,
suspicious, and quirky (he also says that he is "not exactly
inhibited"), but it also somehow resulted in him now being able to find anything, seeing patterns where others would not. His brain uses "Walter math" to explain these things to him. In the backdoor pilot, in
Bones,
FBI Special Agent
Seeley Booth calls Walter's gift "the Finder Power," while Leo Knox calls it "Darna Shellah" and "
Akashvani." Because of his ability to find anything, many powerful and influential people now owe him favors. Walter's catchphrase, as such, is "
I'ma risk it," where he often makes a decision even after Leo legally advises him otherwise. In the pilot, Booth and he are revealed to have "history" and knew each other from their days in the Army. He has a habit of sometimes taking before-and-after
Polaroids of clients. Walter has the knack of also finding out things that his clients did not want to know by finding what people are really looking for, not just what they think they are looking for. According to Walter, in "The Boy with the Bucket," he was named, by his mother, after poet
Walt Whitman. He is depicted as being younger than his literary counterpart, having never been married, nor having any children. Walter's original literary incarnation served in
Vietnam and never suffered brain damage. •
Michael Clarke Duncan is Leo Knox, a
widower and former
attorney. He owns the bar "The Ends of the Earth," located on Looking Glass Key, and he also serves as Walter's manager and legal advisor, and sometimes bodyguard. Leo is also known for his quoting of religious literature, particularly
Buddhism. He calls Walter's power "Darna Shellah" and "Akashvani." According to Leo, he owes Walter his life. In episode three, "A Cinderella Story," Leo is shown to have lost his family (his wife Nina and teenaged daughter Ellie), to
E. coli poisoning. He is based on the character Leonard Martin in
The Knowland Retribution, the first "Locator" book, on which the series was based. •
Mercedes Mason is
Deputy U.S. Marshal Isabel Zambada. While Walter's antics frequently get on her nerves, Walter and she have a "
friends with benefits" arrangement. Isabel has ambitions of being the first
Latina United States attorney general. While she works as a deputy U.S. marshal during the day to gain field experience, she attends law school at night. Her intention is to be "eating dinner in the
White House within six years." •
Maddie Hasson is Willa Monday, a
Romani juvenile delinquent. Willa is very talented with computers, but she is prohibited from using a computer for the duration of her probation. While Willa has been
betrothed to her "cousin" Timo since she was five and Timo was 10, by their mutual "uncle", Uncle Shad, the head of their family, Willa and Timo only love each other as brother and sister. As Willa believes in true love, she wants for Timo to be able to be with the girl he loves, Magdalena. At the end of the season, Willa goes on the run, violating her probation, to avoid her betrothal to Timo. They are not really cousins; it is just the Romani way to refer to one another as such, being the Romani "family". •
Toby Hemingway is Timo Proud, a Romani and Willa's "cousin". Timo is five years older than Willa, and he has a talent for
tarot reading. While Timo and Willa have been betrothed, Timo is himself in love with a mutual "cousin" of theirs, Magdalena. ==Development and production==
