Do No Harm is an American drama that aired from January 31 through September 7, 2013, on NBC. The network placed a series order in May 2012. On November 12, 2012, NBC reduced its episode order for the series from 13 to 12 episodes, due to scheduling conflicts.
On February 8, 2013, it was announced that NBC had canceled the series after airing two episodes, due to low ratings. On April 26, 2013, NBC announced that the remaining episodes would be burned off, beginning June 29, 2013.
The series focuses on Dr. Jason Cole (Steven Pasquale), a successful neurosurgeon with a secret. Every night at 8:25 p.m., and lasting exactly 12 hours, Cole is switched into an alternate, evil personality named Ian Price. Cole has been able to suppress Price by injecting a strong pharmaceutical mixture that sedates their shared body, rendering it impossible for the evil alter-ego to function. But one night Cole discovers that their body has grown immune to the drug and Price has emerged in a rage. Angry at having been suppressed, Cole's alternate personality is focused on wreaking havoc on Cole's life, creating problems which could cost him his romance, career, and even his life.
"Do No Harm" is the twentieth episode of the first season of Lost. The episode was directed by Stephen Williams and written by Janet Tamaro. It first aired on April 6, 2005, on ABC.
While trying to make contact with the outside world from a plane discovered in the jungle tree canopy, Boone Carlyle (Ian Somerhalder) is critically injured when the plane suddenly shifts and crashes to the ground, so Jack Shephard (Matthew Fox) desperately tries to save his life. The flashbacks in this episode revolve around Jack's marriage to a former patient, Sarah (Julie Bowen).
Flashbacks show both the build-up to, and the event of Jack's wedding to Sarah, a former patient whom he "fixed" after she was injured in a car accident. Jack agonizes over his vows, and his father, Christian (John Terry) surprises him by showing up, giving Jack advice about writing the vows by the pool. His father says that Jack's strength is commitment, and that his problem is that he is "just not good at letting go." Jack thinks over his father's words, and eventually writes his vows just in time for the ceremony, finally settling on extolling how Sarah has "fixed" him.
