Lilly Price

Lilly Price is the younger sister of Jesse Price. She is one of the main members of the group, and she often helps members of the group with choices and social problems.

Pre-Nuclear Annihilation
Before the nuclear annihilation, Lilly was Jesse's younger sister. She was too young to have an occupation so she was an elementary school student.

Post-Nuclear Annihilation
Jesse quickly regroups with his sister and they find Garrett soon afterwards. Lilly seems to be quite intelligent due to her being able to help with the group's problems throughout the episodes.
