Cat Marx is a survivor of the outbreak in Infections. Almost nothing is known of her.
South Point, Florida
Nothing is known about Cat's life prior to or as the outbreak began, other than that she was a math teacher at South Point High School.
When Sarah Nixon helps Monica and her friends, she leads them to the classroom. When the group argues about her choice, she defends her.
She is discussing how they can escape the school with the others when Brad is looking through the door.
This list shows the victims Cat has killed:
- Possibly a few zombies.
- Brad (Indirectly Caused)
Brad opens the door to see if the coast was clear while the group was talking. She runs to close it when a walker knocks it open, sending her down. She backs away as walkers get in and the others escape. A walker grabs her leg and bites it, then they surround her. One gets her by her hair. They all pull her down as she screams, devouring her.
- Katie Cassidy said she wanted to stay on the show for only a few episodes, but after filming 'Whatever It Takes,' she wanted to stay for more, but the writers refused to change the script.
