After a lecture in a bookstore for presenting a new released book, the deception expert Dr. Cal Lightman is signing books for the fans when a young woman called Trisha tells him that she had a vision of a murder, but the police do not believe her. He brings Trisha to The Lightman Group and soon he finds that she has multiple personalities: Sophie, the predominant; Trisha, the perfect one; Jessie, a slut; and RJ, who protects the other three. Now he needs to find whether she is a witness or a killer. Meanwhile, the president of the US has appointed his office to learn whether he can appoint Judge Simon to the Supreme Court, and he assigns Torres to verify since he is fascinated with the multiple personality case. However, the judge is uncomfortable with a twenty-four-year-old-woman analyzing him. When Torres finds that the judge had an affair with the daughter of a raped woman that he was judging, she has a bias and Lightman needs to interfere. Zoe tells Cal that she quit her job and will move to Chicago with Emily to open a law office of her own.
"The Core of It" is a great episode and beginning of the Second Season of "Lie to Me". Movies with persons with multiple personalities are usually attractive and this episode is no exception. The fascination of Dr. Lightman with the case forces him to leave an important case for his office in the hands of Torres and he needs to participate in the end. His relationship with Zoe is weird but works very well raising Emily. My vote is eight.
Title (Brazil): "The Core of It"
