Later in the series, it is revealed that Carl Neesan (Wade Williams), the hitman who killed her, was hired by Tru's father Richard.

After her mother's demise, Tru, her younger brother Harrison and older sister Meredith were abandoned by their father and little has been revealed about who raised them from that point on.

Tru possesses the power to relive the current day when a corpse asks for her help in order to save their life, or to help someone whom the person affected in some way.

He is a fan of Dungeons & Dragons and has been in a relationship with Dr. Carrie Allen who, unbeknownst to Davis, is a mole working for Jack Harper.

In the season 1 finale "Two Weddings and a Funeral", Harrison is shot and killed by the jealous ex-husband of a woman he had just met.

His corpse asks Tru for help, but Jack warns her that saving him will cause someone else to die in his place.

Jack Harper, a counterpart to Tru's character, is introduced mid-first season as a foil and possible love interest.

He is there to make sure fate gets its way, and introduces a philosophical aspect to Tru's endeavors: should she be saving the lives of people who may have been intended to die?

While trying to save a child during a neighborhood shootout, he was shot in the back and was physically dead for minutes until being revived by his co-worker.

At some point after that, Jack finds himself reliving days and admits himself to a psych ward, believing that he's gone insane after his near-death experience, until he is approached by Tru's father.

In the second season, Tru and Jack compete to get to someone first — her to save them, and him to restore the order of fate, and maintain what he believes to be the balance of the universe.

He finds out she has cancer and will die regardless, and that she only wants to have one final good day before she kills herself, in order for her sister to get insurance money.

Luc broke things off with Tru over her constant unexplained disappearances and strange behavior.

Jack claims that some woman can prove Tru's story, and manipulates Luc into going to her house carrying flowers, causing her ex to shoot him instead of Harrison.

He formerly had the same "gift" that Jack Harper now does, and had their mother killed because of it by hiring hitman Carl Neesan (Wade Williams).

According to online remarks made by the writers, if the second season had continued, Jensen would eventually have become so fascinated with mortality as a result of his near-death experience that he would become a serial killer.
