Andrea Garnett is the chief engineer aboard the USS Nathan James. She holds the rank of lieutenant commander (O-5) and is fourth in the command hierarchy aboard the ship (following Cmdr. Chandler, XO Slattery, and CMC Jeter). She is one of the three female officers aboard the ship (along with Lt. Kara Foster and Lt. Alisha Granderson).Garnett is responsible for the ship's engines, electricity, and anything mechanical or electrical that keeps the ship moving and functional. She puts a lot of proper faith in Lt. Chung, who is her second-in-command and the most qualified member of her crew besides herself.Garnett was injured in the leg when the ship stopped in Guantanomo Bay to refuel. A group of Middle Eastern prisoners attacked the NJ groups and Garnett was hit by shrapnel while manning the fuel depot. Lt. Chung had to take over her duties while she was in the sick bay, which he did. She gave him a pep talk hen he came to hr for advice after trying everything he could think of to fix the engine and the air conditioning and water filter units; she told him that he'd qualified on his engineering test faster than anyone she'd ever seen, and she had faith that he would figure something out. When the electricity and air conditioning finally came on, she smiled in the sick bay and congratulated Chung.Garnett kept the crew calm and organized when the Maryland State troopers (on orders from Amy Granderson) took the ship hostage. She especially had to calm down Bacon Crowley, telling him that there was a time and place to revolt. When O'Connor turned the heat up in the room where the crew was being held, Garnett managed to convince the troopers that they should all be moved to the mess hall, where they could use the head and have water; she also old him that the heat was making her crew agitated and given that there was over a hundred of them and only twenty-five or so troopers (despite the guns), she didn't know how much longer she could control them and the troopers would eventually be overrun.The movement of the crew to the mess hall allowed some of them to escape (while Bacon provided extra cover). While in the mess hall, Bacon told Garnett that now seemed to be the time to revolt, and he showed her the knife he'd hidden in his pocket. Garnett agreed and Bacon cut him and Garnett free of their plastic handcuffs; the knife was then passed around in secret so that other crew members could cut themselves free as well. After Cruz, O'Connor and Miller shot the troopers and freed the crew, Garnett rallied them to get the weapons provided by the trio and take back the ship from the rest of the troopers on board.While back in Norfolk, Garnett was part of the land crews that delivered the cure to safe zones while looking for their families. She went by her house and saw that her husband's car was missing, so she held out hope that he and their daughter had gotten to safety. Later on, she was back on the ship in her room, alone. Chandler came to see he as he'd heard she was back on the ship but no one had seen her since she returned. She confessed to him that she'd gone to a safe zone that had kept records of who arrived and who died; she saw the names of her husband and daughter on the deceased list, and was still in shock. She broke down crying on Chandler's shoulder. Show less «
