Percy recognized the monster outside of the car as a half-bull, half-man hybrid outside of the ca. If the creature attacks, his mother encourages him to jump to the side because a bull can't readily shift courses. When the bull charges, Percy does so, causing the creature to become enraged. On the road side, the monster assaults his mother and Grover. Percy's mother is grabbed by the neck by the bull-man, and she vanishes in a flash of golden light. Percy, enraged, rips one of the monster's horns off and slams it into one of the monster's ribs, defeating the creature. Grover and Percy pass out on the farmhouse's porch after Percy assists Grover to safety. A young girl recognizes him as the "one".
