Derek Reese discovers the CPU that Cameron saved while burning the last Terminator.  He continues to try and make his point that none of the machines can be trusted and blames her for his buddies getting killed.  Cameron tells them she saved it for the information on the chip.  John believes her and hookos it up to a computer to retrieve images from it.  They discover that the Terminator was posing as a man named Vick in order to push through development of a traffic control system that could later be used as the eyes and ears for SkyNet.  Sarah and Derek move to disable the system by implanting a virus.  Meanwhile, Cromartie arrives at John's school looking for him.  Cameron asks a friend to pose as John to fool the machine.
