Caroline



An unseen character in the single-player campaign of Portal 2, 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.

From the recordings, it is clear Cave Johnson holds her in high regard, remarking that "she's the backbone of this facility".

Caroline is voiced by Ellen McLain.
