CAROLINE

Caroline was the personal assistant to former Aperture Science CEO Cave Johnson, until later becoming his successor. Not much is known about her character, as she is only heard briefly through a small portion of Cave Johnson's prerecorded audio messages. it is believed that Chell might be Caroline´s daughter.

Although the amount of time she became CEO is unknown, it is clear that Johnson had praised her enough to have her essence extracted into acore to oversee the Facility's operations, the core of which became GLaDOS.
