Curie

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

Background
Curie began as a Miss Nanny robot intended for use in the secret partition of Vault 81 as a lab assistant. Only a handful of the vault's scientific staff were working in the vault when the Great War hit, which led Dr. Kevin Collins to modify the Miss Nanny and give it greater operational freedom so that it could conduct its own experiments. Dr. Collins added a feminine personality with a French-accented voice, programmed in the natures of famed intellectuals such as Marie Curie, Immanuel Kant, and Albert Einstein, and christened his creation "Curie", an acronym based on the robot's original designation.

As Curie began taking on greater responsibilities, Dr. Collins insisted that the other scientists treat her as they would a human, and even set aside a terminal for her personal use, an act of kindness that initially bewildered Curie, but which she later appreciated. As the scientists grew older, Curie continued assisting them and gradually developed a degree of self-awareness and independence that surprised even Dr. Collins.

When the scientists died, Curie curated their remains, storing the bodies of two in empty lockers and cremating the third according to his wishes. For decades, Curie took on their research alone, and in 2204 completed Vault 81's original initiative: she perfected a panacea capable of curing every disease that afflicted humanity. Unfortunately, she was still beholden to her programming and was incapable of leaving the secret partition without express authorization from a Vault-Tec employee. For 83 years, she waited idly for Vault-Tec security to arrive, watching the escaped mole rats that had been used as test subjects run free.

When Curie was finally discovered by the Sole Survivor in 2287, she elatedly handed over the remaining unexpired dose of the cure and decided to travel with the Survivor in order to seek out new research opportunities in the Commonwealth. Eventually, she realized that her Miss Nanny body lacked the inspirational spark that all great scientists had, and requested to be transferred into a new body.

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).

Effects of player's actions
Upon gaining the admiration of Curie, she will tell you about a breakthrough she has made with Mutfruit, and give you the Combat Medic perk, which heals you for 100hp once a day when you fall below 10% health.

Bugs

 * When inside Vault 81 it is possible for Curie to go up to a wall and use the saw blade as a blowtorch mimicking the vault dwellers repairing the vault.
