Jill Tuck, the ex-wife of John Kramer, appears briefly in "Saw III" as part of a memory that John recalls while he is undergoing brain surgery. She is interrogated by FBI Agents Peter Strahm and Lindsey Perez in "Saw IV", revealing Jigsaw's backstory. In "Saw V", after John's death, Jill visits his lawyer to hear his will, during which she is bequeathed a box containing his last intended test subjects, including one test that Jill must carry out herself. Submitting to his final wishes, Jill placed Mark Hoffman in a seemingly inescapable trap, intending to kill him.
