Betty, also known as the Gyroscopic Liability Absolver and Disc Operating System, was a Personality Core cut from Portal 2. It was to assist the game's protagonist, Mel, in brief appearances prior to each test.
During the F-STOP-stage of Portal 2`s development, when the game featured Mel as the player character and Cave Johnson as the main antagonist, Betty was slated to be Cave Johnson's assistant during the experiment. Her placeholder model consisted of the Morality Core attached to a lamp prop from Half-Life 2 on wheels. Once Cave Johnson explained a test to Mel, Betty's role would be to pop into the room and deliver a short speech of legalese that absolved Aperture Science of any responsibility for the injuries that may occur in the test chambers. Faliszek and Wolpaw mentioned that the dual dialogue of Cave saying one thing and Betty saying another was inspired by how commercials for medicine often featured imagery of puppies while a stern voice warned about side effects such as "rectal bleeding." Betty's technical name, GLAaDOS, was to be the only cameo reference to GLaDOS in the sequel.
