Amata is the Overseer's daughter. Her mother died when she was just two years old. She loves her father dearly and is very loyal to him, but she hopes to change his stance on isolationism. She does not want to defy Alphonse but longs to experience the outside world. The Lone Wanderer and Amata have been best friends since childhood, drawn together by the common bond of not having known their respective mothers.
In 2274, James performs a medical exam on Amata with her father present. James writes in her medical file that she is concerned that her father doesn't trust her and that his insistence on being present precludes any possibility of doctor-patient confidentiality. James, however, believes that Amata can be trusted to avoid making bad decisions.
When Amata completes the G.O.A.T., she is informed by her teacher Mr. Brotch that she is on a supervisory track.
Growing Up Fast: On July 13, 2268, Amata decorates the cafeteria in anticipation of the Lone Wanderer's tenth birthday party. As a gift, Amata gives the Lone Wanderer an intact copy of the 14th issue of Grognak the Barbarian.
Future Imperfect: On August 3, 2274, Amata is harassed by the Tunnel Snakes gang near the classroom. The Lone Wanderer can help Amata, help the Tunnel Snakes, or leave Amata with the Tunnel Snakes.
Escape!: Amata awakens the player character with news of James' escape from the Vault. She offers a gun and has a plan for the player's own escape. Toward the end of the quest, the player finds her being interrogated by her father and Officer Mack. If the player refused to take the gun from Amata she will pull it out, kill Officer Mack, and run into another room.
Trouble on the Homefront: After The Waters of Life there is a new radio signal in the vicinity of Vault 101, the Vault 101 distress signal from Amata. She gives you a brief explanation on the events leading up to that day and gives you the password to open the vault door. Amata will mention the Vault is in trouble and that she needs your help to stop the Overseer.
Amata's Fate: If you complete the Trouble on the Homefront quest by destroying the Vault's reactor, there is a random encounter involving Amata and Enclave soldiers. They will ask her for the location of Vault 101, which she will give to them. Afterward, the soldiers will open fire and kill her, unless the player is fast enough at killing the Enclave, at which point she will walk away, and scold the player if engaged, she will only say, "Stay away from me - this is all your fault!".
Amata appears floating face down during the hallucination that occurs while intoxicated with punga plant seeds in the Point Lookoutadd-on.
Amata appears running down the hall towards the player during a hallucination inside Vault 106. Firing on her figure will result in a Karma loss.
When you leave Vault 101 for the first time, Amata (if the player took the pistol) might be knocked out by any remaining guards. However, if Amata kept the pistol, she will fire upon and kill the hostile guards.
If you complete the Trouble on the Homefront quest by killing the Vault overseer and convince her it was your only choice, she will say, "I'm sorry. You're a hero... and you have to leave." This is a homage to the original Fallout at the end of which Jacoren says the same line. (Certain dialogue choices may avoid this line)
