The Party Escort Bot Shadow or Party Associate Shadow, is a mysterious pink-eyed Core Shadow and Android Shadow, During the events of Portal, GLaDOS Shadow refers to the Party Associate after failing her attempt to kill Cameron at the end of the final test chamber. As Cameron did not follow GLaDOS Shadow as the latter instructed him to "place the device on the ground, then lie on [his] stomach with [his] arms at [his] sides" which was described as the "party escort submission position", it is presumed that the Party Escort Bot Shadow was required to travel to the surface in order to retrieve him and "escort him to the party".
