The facility is also run by a Personality Core, the Central Core. Most Personality Cores are spherical (Personality Spheres) but some of them, like GLaDOS and ATLAS and P-body, are not. This gave the creators a new idea of tying the Caroline personality to GLaDOS, and wrote part of Portal 2 's story around GLaDOS discovering her human past, using it to succeed, and then immediately forgetting about it by wiping it away.Īperture Science Personality Constructs, or Personality Cores, are robots created by Aperture that have their own personalities. However, instead of hiring a voice actor for a handful of lines, they decided to economize and reuse McLain (the voice of GLaDOS) to voice the character and naming her Caroline. Valve had created the "Greg" character to be a straight man to the Cave Johnson character. After their victory, GLaDOS thanks the Caroline persona for her insights, and then promptly deletes the personality. In the conclusion of Portal 2, GLaDOS, trapped in her potato form, comes to recall the Caroline persona, and accepts this to form a truce with Chell to defeat Wheatley. Caroline would ultimately become the personality core of GLaDOS. As Johnson's health deteriorated and as he became mentally unstable, Johnson ordered that Caroline be put in charge of the facility.

Some of the song’s lyrics are scribbled on the walls of the den. In one of those dens, The National's song " Exile Vilify" can be heard from a radio. The dens in Portal 2 contain paintings of Ratman among the scribblings. Ratman has pasted pictures of companion cubes on their heads. Among the scribblings there are also pictures of a family watching television in the 1950s, and pictures of portraits of Sam Rayburn, Theodore Roosevelt, and Calvin Coolidge. Auden's " Funeral Blues", Emily Brontë's "No Coward Soul Is Mine", Emily Dickinson's " Because I could not stop for Death", and Henry Wadsworth Longfellow's "The Reaper and the Flowers". The scribblings also include pastisches of several poems, including W. Also, the player can hear Ratman ranting on the other side of the wall in the last den of Portal 2.Īmong the wall scribblings in the Portal dens is the sentence "The cake is a lie", which has become an internet meme. Throughout Portal 2, it is hinted through more scribblings (which look more recent) that he has awakened from cryogenic sleep and is wandering around the complex again. In the last panel of the comic, Ratman places himself in cryogenic storage animation. After watching her defeat the computer, he managed to escape the facility, but returned to assure Chell would be put in indefinite cryogenic storage animation after she was dragged back inside, suffering a serious injury (a shot in the leg from a turret) to complete this. During events in Portal, he worked behind the scenes to scribble messages and warnings to Chell on the walls, leading her out of the testing chambers and towards GLaDOS. The Lab Rat comic reveals that, despite his madness, Ratman identified Chell as a rejected test subject due to her high tenacity, and moved her to the top of the queue for testing. Already sceptical of the computer, the man fled from the gas and kept himself hidden from GLaDOS' view, slowly becoming more insane over an unknown stretch of time. In Prior to GLaDOS' rampancy and the neurotoxin release, Ratman was Aperture scientist Doug Rattmann. Ratman’s full appearance is only seen in the Portal 2: Lab Rat webcomic released by Valve prior to Portal 2 's release to tie the story of the two games together. In the two games there are various hidden rooms, so-called "Ratman dens", where Ratman has left scribblings and paintings on the walls. He was a former scientist working at Aperture and one of the few who survived when GLaDOS flooded the facility with neurotoxin. The Ratman is a character in both Portal and Portal 2.
