Matriarch Teersa, who has always wanted to help Aloy.
Bast seems willing to talk to Aloy, but his mother says to shun her
Aloy is very lonely, and wants to help and befriend the children. Being rejected for no logical reason makes her furious.
Unlike most Nora, Aloy is extremely curious and exploring these ruins only feeds her curiosity. This event drives her to explore more ancient technology throughout the game. Having access to the Focus, she can see the stories left behind by the ancient people, which is a balm to her loneliness.
Rost, an exile, is given Aloy to raise by the Nora Tribe's High Matriarch Teersa. He is told nothing about her or why her own parents cannot raise her. She is to be raised as an exile, like him.
Rost is a traditional Nora. He does not like Aloy having the Focus, but he respects her and doesn't force her to take it off.
Aloy loves Rost but is willing to defy him to have something that helps her feel less alone. This is an example of her stubbornness, which is only increased by these events.
As a child, Aloy found it difficult to live life as an exile, and tried to interact with other children. While the children at first seemed interested, their mother told them she was to be shunned
Even though his family did not thank Aloy, the Brave remembers her and helps her later in the story.
Aloy's choices are validated since she uses her Focus to save the Brave. This solidifies her confidence (and stubbornness), despite lack of thanks from the Brave's family.
Aloy was hurt deeply emotionally by the rejection of the other children, and ran away. She fell into an ancient ruin, and there found a technological device called a Focus.
Bast was taught to shun exiles, and became hostile toward Aloy.
Aloy wanted friendship, and was rejected. She learns she will not be helped b the tribe - she can only depend on herself and Rost.
Finding her Focus gave her a new world to explore. She learned to use it to get information from the world around her, even though Rost told her not to.
During her training, Rost and Aloy encountered a Nora Brave wounded and trapped by dangerous machines. Aloy proved the usefulness of her Focus and her own resourcefulness by tracking the machines and saving the Brave, but the tribe gave her no thanks.
After saving the Brave, Aloy again encountered the group of children from before. One child responded to her attempts to interact by throwing a rock at her. Aloy responds based on a choice by the player, but either way shows her independance and strength.
