Mechanical Paradise had plenty of information on the Old World. This allowed Genava to lock onto the principal's office without much effort.
After a few trial-and-error attempts, he pushed open the right door. Of course, he had already used various methods to confirm that there was nobody in the office. Otherwise, he would patiently wait for someone to report their work to the principal. He would take the opportunity to tailgate them or circle to the back of the building and climb in through the window.
After entering the office and gently closing the door, Genava went straight to the mahogany desk with a computer.
He was in no rush to turn on the computer. He first picked up the photo frame on the table and 'memorized' the faces of the principal's family of three into his storage drives.
