Amata

Amata is the daughter of the Overseer of Vault 101. She is a close friend of the Lone Wanderer (the PC), having known him/her since they were toddlers. It's implied that the PC (regardless of gender) may have a crush on her. The player is forced to make a choice when he finally confronts the Overseer: kill him to take revenge for the unnecessary murder of Jonas and gain his keys to his escape tunnel, or spare him and find their own way out. It is also possible to threaten the Overseer that the player will harm Amata if he is unable to escape the vault. This will also lead to the Overseer giving the PC the key to his office. If the player kills him, the player's friendship with Amata suffers but can possibly be spared depending on how they explain it to Amata. The player asks her to accompany them in their first venture into the outside world but she refuses, regardless of whether or not her father is killed.

The game hints at a possible budding relationship between Amata and the PC, but this hint is more heavily implied if the PC is male. At the start of Escape!, the PC can say he/she was having a dream about Amata. She replies to the male PC by telling him not to be a smart-mouth, while her response to a female PC is "Eww! Don't be gross!", implying that Amata herself probably wouldn't be interested.

After returning to Vault 101 the vault door is locked and cannot be opened and there is a new Radio signal. It is 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. The Trouble on the Homefront quest begins here.

Upon entering the vault a Vault 101 Security officer (Gomez) confronts you and if you answer positively he will lead you to see Amata or Amata's father the Vault 101 Overseer. This quest can still be done if you killed The Overseer earlier, as another person will have taken over.

Amata will mention the vault is in trouble and needs your help to stop her father. There are multiple ways of accomplishing this - by force, by reason or by Speech skill. She pleads for you not to kill her father. Afterwards you will have one final chat with Amata and she will ask you to leave the vault forever. If you do leave without killing everyone the Trouble on the Homefront quest will end and the vault will close permanently.

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.
