Returning to 2007, Walker is told that his trip caused a greater change to history than Parker's original journey and he realizes the robot must have still been operational, causing havoc to history with its later actions. To restore order, Walker returns to the mine and stops the machine's rampage, again with M'Boto's help. On his return to 2007, he learns that history is now back on track with only one minor ripple left as a result of his trip, nothing that would concern the TEC. Readers realize that Walker's presence allowed M'Boto to become wealthy and become a political activist who helped lead the end of racial segregation in South Africa in the 1950s.
