Caroline



Caroline is mentioned throughout the single-player campaign of Portal 2, as the secretary to former Aperture Science CEO, Cave Johnson. Not much is known about her character as she is never seen, instead only heard through 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.
