## Biography

### Early Life and Background

Cassie Levitt was born in 2003 and the third child and second daughter of Joseph and Tracy Levitt, and the younger sister of Sara and Adam.

 "Immune?"
 "...Yeah,*"
—Bill Denver and Max Everett about Cassie's immunity to the bioweapon[src]

## Overview

### Personality

Cassie is a sensitive girl who has been severely affected by the split of her family and the horrors unleashed on Langdom during the events of the series. These events have transformed her from a bubbly young girl with a love for classic rock into a catatonic shell of a person, rendered numb to the horrors she has seen.

Eighteen months later, Cassie has come to believe that the extinction of humanity is inevitable, a perspective both Adam and Abby disagree with. After settling on Searchlight Ranch, Cassie appears to change her views on the world, saying to Lucas that maybe there could be hope for the human race. Over the course of the second season, Cassie toughens up considerably, learning how to shoot from Lucas and even mustering the courage to kill her first Turned to defend Abby, her pregnant sister-in-law. When the group escapes Searchlight, Cassie is one of the few members who is able to think straight and not give in to the panic of their situation, deciding to closely follow the example of her brother and sister-in-law.

## Relationships

### Adam Levitt

Adam is very close and protective of his sister, having taken on the duty of protecting her from the degenerating world around her. Despite being her older brother, Adam acts more like a father to her, willing to go to any lengths to keep her safe. He keeps her immunity to dollar rabies a secret in case any survivors they come across are able to warn FRF soldiers hunting down Langdom survivors, only revealing her immunity whenever her bite is uncovered by other survivors.

### Charlie Everett

Cassie and Charlie were close friends growing up, always sticking up for each other. When they were children, Cassie taught herself sign language in order to communicate with the mute Charlie. She was devastated when the group got separated, but is confident that Charlie survived Langdom.

### Lucas Mann

"*You know...if **you** ever get bitten, and I'm the only one around...I'd do it for you,"
 "Hah...thanks, kid,*"
—Cassie and Lucas as they sit around the fire[src]

Cassie becomes very friendly with Lucas during their time on Searchlight Ranch, with Lucas deciding to show Cassie some basic tips for surviving on her own. When Cassie's bite was revealed, Lucas regretably decided to put her down, but let her go upon discovering that the bite was healing and Cassie was immune to dollar rabies. Later, following the fall of Searchlight, Lucas and Cassie sat next to each other at a campfire, showing no hard feelings between them, with Cassie even saying that she would be able to put him down if he ever got bitten, which Lucas appreciates.

### Bonnie

Cassie and Bonnie become friendly during their time on Searchlight Ranch.

## Trivia

* Cassie is one of six known survivors of the Langdom Experiment, the others being her brother Adam, her sister-in-law Abby, Charlie Everett, Lloyd Smith and Frank Thornstein.
* Cassie is currently the only human known to be naturally immune to the Langdom Bioweapon, having been bitten but showing no signs of infection.
	+ Bill Denver theorizes that the government knew someone in Langdom was immune to the new bioweapon and released it on the town specifically to find whoever was immune so that they could modify the bioweapon against this immunity. This theory is further backed up by Adam noting that military patrols have been searching for Langdom survivors in *Season 2.*
* Until "*Long Night*", Cassie was the only main character from *Season 1* to have not yet killed a single Turned or human. She finally killed her first Turned in the episode while defending Abby.
