She is a possible companion of the Sole Survivor. The state-of-the-art CVRIE was designed to be the guardian of Vault 81 , responsible for preserving the knowledge amassed by the Vault 81 scientists, as well as ensuring that every single one was aware of the significance of the mission undertaken within the halls of the vault. Due to the overseer's sabotage, none of the science staff received a notification about the drill that would have allowed them to enter Vault 81 in time to survive the Great War.
Burrow was already on-site. They reported to the research area and were sealed inside. Despite their severely low numbers all but ensuring that the generations-long research plan would die out, the scientists still had state-of-the-art equipment, centuries' worth of supplies and the Contagions Vulnerability Robotic Infirmary Engineer CVRIE , meaning that with even their limited manpower, they could still be a threat to the residential population. When she was notified of this development, Overseer O.
Olivette was mortified and attempted to play for time [9] while maintaining an aura of camaraderie, taking care to not reveal her intentions. While the mood among the three researchers remained stable thanks to Collins and Curie, Olivette knew they still had access to the nozzles and could release the pathogens for a Stage III trial, or worse.
When a minor mishap with the mole rat population was resolved and Stage II was progressing rapidly, Olivette made her decision. Putting her plan into action, the overseer personally sabotaged the delivery nozzles inside every residential quarter and room on their side of the Vault. When the researchers began to notice Burrow, specifically , she broke off all communications with them and kept hold of her terminal to prevent anyone else from contacting them.
Eventually, Curie became their inheritor, [13] watching as they fell one-by-one. Flint was the first to die, [14] possibly killed when one of the mole rat test subjects named Clyde escaped his cage and spread the pathogen he'd been injected with, [15] while Collins and finally Burrow both died of old age. At each of their passings, Curie interred them in makeshift coffins made of old lockers and continued the scientists' work on her own.
