Zorish grimaces, steeling himself against the memory dump program that is now ingrained in his own brain. The images that flash on the holoscreen are messy and indistinct at first, snippets from both Tamora and Zorish's life that form a sort of fast-motion nonsensical movie. After awhile the information begins to sort itself out into coherent data, beginning with Zorish's appointment as the Director of Human Affairs, a position that was agreed upon as a sort of tenuous compromise between the Council, Visser One and Visser Three.
The images flash forward to Zorish working undercover, on earth, for several years. First in the body of a middle-aged corporate guru and then, in an attempt to gather data about youth culture and the ease of human manipulation at a young age, in Tamora.
There is only one Yeerk Pool that Zorish frequented, the heavily populated Southern California pool that has become large enough to be read on Andalite sensors. Zorish seems to be aware of another pool of equal size somewhere in the Manhattan area, but details are sketchy.
Further investigation reveals basic schematics of the areas Zorish frequents on the Blade Ship: bridge, mess halls, Yeerk Pool, quarters and docking bay. The names of a few other high ranking Yeerks also appear, along with the name of Zorish's "superior", a human-controlled Yeerk of the rank Sub-Visser Fifty-One who, despite having a lower rank and a somewhat worrisome companionship with her host Taylor, was put in control of the major tactical decisions over Zorish.
