Lance was a boy who was popular before the FAYZ. He was a part of the Human Crew. Because Zil makes a big deal out of how good-looking he is and how he wishes he could be like him, it's safe to assume he looked up to him. Zil also states that it was Lance that made the Human Crew cool. Lance is athletic and up for carrying out plans, but lacked in making them. He was a fairly dedicated member of the Human Crew, and quite influenced by Zil's decisions.
Zil begins to notice that Lance has a twisted mind later on in the book. He was the one who figured out how to kill Hunter, and he always enjoys beating on freaks.
