Lieutenant Commander Jaimie Petrelli was a Starfleet officer in the late 24th century. She served aboard the USS Baldwin as tactical officer during the Dominion War, and eventually became executive officer.
Jaimie was initially assigned to the USS Renegade as a junior security officer. By late 2373, she had entered into a relationship with Steve Guaraldi. In November of 2373, Renegade was assigned to a mercy mission to transfer medicine to Archer IV. During the mission, pirates attacked the away team with photon grenades. Jaimie held them off and allowed the away team to complete the mission. For her actions, she received a Starfleet Medal of Commendation. (USS Baldwin: "Family Affair") Unbeknown to her at the time, she had become pregnant. However, the fetus was taken from her womb by the Renegade's doctor, Claude Eccleston, under pressure from Orion Syndicate operative Malina. (USS Baldwin: "Mother and Child", "Family Affair")
Jaimie was one of the first crew members assigned to the USS Baldwin as the Alpha-shift tactical officer under Captain Patrick Ingrum (USS Baldwin: "The Find"). Her duties as tactical officer included a spot as gamma shift duty officer (USS Baldwin: "Storm Front"). Patrick had a habit of referring to her by her initials. (USS Baldwin: "Wartime Productions")
In mid-2375, Jaimie took command of the ship when the remaining senior officers became unavailable. When the previous first and second officers, Reinette Hernandez and Gloria Dawson, took new positions elsewhere, Jaimie took acting command of the Baldwin and subsequently accepted the position of executive officer. (USS Baldwin: "Only the Young", "Trouble in Paradise")
When Patrick began a relationship with Bridget, Jaimie was given the final word on all matters related to Bridget, in order to prevent a conflict of interest. She also took Cadet Dorian Collins under her wing, becoming her mentor. (USS Baldwin: "Evolution", "Blue Clear Sky")
In early 2377, Khan had captured a Jem'Hadar battleship and captured Patrick. She lead a task force of Laura Bennett, Roslyn, and Kristy Elias on a mission to rescue Patrick and destroy the battleship. (USS Baldwin: "Departure") In 2378, she was awarded the Christopher Pike Medal of Valor for her display of leadership and bravery during the mission. (USS Baldwin: "Family Affair")
In 2378, Jaimie discovered that she was pregnant. During a mission to deliver medical supplies to Salva II, Jaimie found a young boy named Joshua alone in the hospital, and he indicated that he had been a slave of the Orion Syndicate. She brought him back aboard the Baldwin. A DNA test identified Jaimie as his biological mother, and a tattoo on his back confirmed he was a slave of the Orions. (USS Baldwin: "Mother and Child")
Jaimie had a older sister, Kelly, who had served as second officer aboard the USS Hood and subsequently became XO of the new USS Edmund Fitzgerald. The two sisters get together whenever they can (USS Baldwin: "The Find", "Wartime Productions").
