How did the Morlock's plan go abruptly wrong?

       After leaving the palace, Weena and the Time Traveler set up camp in the woods with a fire. The fire goes out while they are sleeping, and the Morlocks begin to attack. Suddenly, the forest catches on fire and the Morlocks scrammed, but Weena dies in the fire. The Time Traveler makes his way back to the White Sphinx in outrage. The Time Traveler states, "And now came a most unexpected thing. As I approached the pedestal of the sphinx, I found that the bronze valves were open. They had slid down into grooves." The Time Traveler is excited that he can see him machine within the sphinx, but he knows that it must be a trap, yet he disregards it and enters it. Thinking that he will be fine with his matches, he has nothing to strike them on and the Morlocks jump all over him. The Time Traveler fights them off, puts the levels back in place, and shoots into the future!
