Episode 1— The Core of It

A young woman approaches Lightman at his book signing, claiming she witnessed a murder. Lightman discovers that she has multiple personalities and suspects that one of them may have seen the crime. He shifts his focus from assisting Agent Reynolds in vetting a potential Supreme Court nominee to pursuing the woman's case, passing the nominee's evaluation to Torres. The nominee initially dismisses Torres due to her age, but she sets aside her initial biases to assess the facts objectively. Lightman eventually unlocks the woman's original personality, who aids in identifying the true murderer. Meanwhile, Zoe informs Lightman that she plans to take their daughter, Emily, and move to Chicago to establish her own law firm. In response, Lightman buys out her share of The Lightman Group to support her new endeavor.
