She is courageous and seems very calm and collected. When Amy and Dan told her about the "treasure hunt" in Maze of Bones, she reacted calmly as if it was normal. Nellie likes music, and rarely takes her iPod's headphones out of her ears. She loves cranking her music up as loud as the iPod can go. She is also mischievous, as it is shown when she shook up soda and opened it in Natalie's face. Nellie loves cooking, a trait she shares with her dad.
Nellie Gomez was supposedly hired by Amy and Dan's Aunt Beatrice to be their au pair, but Grace actually hired her for the job. She was the perfect candidate, her family having guarded a Cahill treasure (the snake earring as shown in Storm Warning) and also having the necessary skills. Aunt Beatrice was threatened by Grace that she would not get part of her will if she fired Nellie. In the Maze of Bones, on the way to Grace's funeral, Aunt Beatrice says, "As soon as we get home I am firing that Nellie." She accompanies Amy and Dan throughout the Clue Hunt. She was kidnapped by the Vespers and shot in the shoulder during captivty.
Nellie has a father, Pedro Gomez, a mother (unknown) and a sister (unknown). She is also the legal guardian of Amy and Dan Cahill, along with Fiske Cahill. She was thought to be an employee of Beatrice, but was actually hired by Grace.
Nellie has been described as having a silver snake earring in her nose, and multicolored hair. She has light-medium skin and dark brown eyes.
Nellie is the au pair for Amy Cahill and Dan Cahill. She agrees to help them on their quest for the 39 Clues, traveling all around the world. Dan has commented that he liked Nellie because she "made amazing waffles and cranks her iPod up to brain damage level." Nellie takes care of the cat, Saladin, an Egyptian Mau formerly belonging to Grace Cahill. Nellie is fluent in many languages, and helps Amy and Dan decipher meanings of Clues. She becomes close to the two children she au pairs, becoming worried to frantic if they are gone off hunting Clues for more than a few hours. She is not that amazing to everyone she meets, however. The Kabras are disgusted by Nellie, their disrespect for her increasing after she sprays her Coke in their faces, after Natalie accidentally spills her whole vial of poison into it during turbulence. She also is Sammy Mourad's, the scientist that replicated the serum in Unstoppable, girlfriend.
