Curie

Curie (short for "Contagions Vulnerability Robotic Infirmary Engineer") is a companion in Fallout 4.

Background
A former assistant in various laboratories, Curie, a sentient "Miss Nanny" robot, ventured into the wasteland to do some independent research. She has a degree in science, medicine, and the French language, but will torch her enemies with her flamethrower in self-defense.

Doctor Burrow programmed her to inherit natures of great scientists (like Marie Curie and Albert Einstein), added a French accent to Curie's speech, and insisted that the other scientists of Vault 81 treat her as a human. He gave Curie her own personal computer, and had her take notes on their work. She continued working on the scientists' research after they died, but failed to make any progress, something she blamed on a lack of experience and resources.

She remained trapped in a sealed section of the vault, where the original overseer imprisoned the scientists before they could conduct their experiments on the vault's residents, until her discovery by the Sole Survivor in 2287.

Other interactions
Curie will occasionally give player character stimpaks. Like most other companions, she will also make comments regarding places visited or generally about the Commonwealth.

Curie will request to leave if she enters Vault 81, but her reputation will not change.

Effects of player's actions
Curie can be rescued from her labor. In addition, Curie can become a synth if the player character asks Doctor Amari in Memory Den to transfer her memory in one of the synth bodies (quest Emergent Behavior).
