<P> During her first season on the show, she is paired with Executive ADA Ben Stone (Michael Moriarty). During the prosecution of a rape case, he threatens to fire her after she fails to share key information she learned while interviewing a witness, which subsequently comes out in trial, jeopardizing the case . Stone eventually relents and refuses to accept her resignation, relating to her because of a key mistake he made early in his career . In another case, Kincaid temporarily resigns after it is revealed she and a judge that the DA's office is prosecuting were once lovers, possibly jeopardizing the case against him . </P> <P> After Stone resigns from the DA's office, she is paired with Jack McCoy (Sam Waterston), the new Executive ADA . In the two seasons they appear in together, she and the brash, competitive McCoy often butt heads over the social and political implications of their trial strategies, as well as McCoy's penchant for going to legal extremes to get a conviction . The two eventually form a close bond, however, and it is hinted in several episodes that the two become lovers . </P> <P> In the episode "Aftershock", Kincaid is killed just as she is considering leaving the DA's office; her car is struck by a drunk driver as she takes an inebriated Lennie Briscoe (Jerry Orbach) home from a bar . McCoy is haunted by her death, as evidenced by his intense, legally questionable efforts to prosecute a drunk driver and his indignation at being questioned about the circumstances of her death . Following her death, Briscoe re-enters Alcoholics Anonymous and remains sober for the rest of his life; it is implied that he feels his drinking was responsible for her death . </P> <P> In one episode of Season 6, "Corpus Delicti", Kincaid was played by Jill Hennessy's identical twin sister, Jacqueline Hennessy, in certain courtroom scenes . This was because Jill was filming in Baltimore for the crossover episode of Homicide: Life on the Street, which was broadcast a few weeks later . Jacqueline Hennessy's performance was uncredited . </P>
