Zoe Hammerstein was a promising young violinist invited into Vault 92.
She was excited and felt little bit out of her league when compared with the other, more accomplished, musicians in the vault. She was one of the first to feel the effects of the uncontrolled white noise brainwashing implemented by Overseer Rubin. After being assured by the vault doctor that she was just stressed, she began losing her mind completely. As revealed in her terminal entries, she had a crush on Parker Livingsteen.
Her terminal entries become less legible because of the effects of the white noise. The first entry is perfectly fine, the second one has some spelling and grammar errors, the third has many more errors, and the last one is hardly legible at all.
This character is mentioned in Fallout 3, but does not actually appear in the game.
