Though often confronted by people's skepticism, Lightman uses any technique he deems necessary to reach the truth, however elaborate or confronting . He is divorced and shares custody of his teenage daughter . He cares deeply about his colleague Gillian Foster; and there is a chemistry between them that has yet to develop into anything more although, in the Season 3 finale, he confesses to his daughter that he loves her . His mother committed suicide while he was still young, an event that led him to discovering and researching microexpressions . There is evidence he was involved with British Intelligence in Northern Ireland . Lightman also mentioned interrogating militant suspects recalling his release of one suspect resulted in the shootings of 6 and the deaths of 3 in a murder operation the suspect subsequently carried out . He has also admitted to being an MI6 intelligence agent during the Yugoslav Wars (1994) in an attempt to gain the trust of an intelligence agent that he was interrogating .

While she occasionally disagrees with some of Lightman's actions, she has an open pact with Lightman: not to let their professional skill interfere with coworkers' personal lives . Her husband's lack of candor often challenges this: When Cal believes her husband, Alec, is cheating on her, he simply ignores what he is seeing, much to Torres's dismay . It is later revealed that he was not cheating on her but was trying to overcome his drug addiction; they promptly divorce . Gillian had adopted a baby (Sophie) who was eventually returned to the birth mother . This character is based on Dr. Maureen O'Sullivan, Emeritus Professor of Psychology at the University of San Francisco . </Li> <Li> Brendan Hines as Eli Loker, an employee of The Lightman Group . Unlike Torres, whom Lightman calls "a natural", Loker acquired his skills in "reading" people through academic education and practice . During Season 1, he also adheres to Radical Honesty and thus rarely lies, even if that makes him appear rude or undiplomatic . Lightman demoted him to an unpaid intern after, despite Foster's warnings, he divulged sensitive information to the SEC while working on a case . However, he is later promoted to Vice President, which makes a rift in any developing relationship between him and Torres . </Li> <Li> Monica Raymund as Ria Torres, an employee of The Lightman Group and Dr. Lightman's protégé, who was recognized as a "natural" while she was still working as a TSA Agent .

She has a half - sister who was in juvenile prison and is now enrolled at a private school . </Li> </Ul>
