Zack Patterson

Before Camp half-blood
Zack was raised by his father, Leonardo Patterson, an extreme lover of Athena. Zack grew up very wise, and very knowledgeable of his mother. When Zack was 12 years old, Leonardo got Google Search cancerand the last thing he did was he told his son who his mother is and where Half-Blood Hill was. Because Zack now knew that all of those Greek Myths were true, he realized that the Underworld was also real, that's where his father was heading.
