As Roberta is starting to lose grip Sarge tries to calm her. She tells the story of how she was once trapped in the trunk of a car for 9 days after her family turned zombies. At one point; she is dragged out of the crate she was supposed to wake up in while still unconscious and is nearly sexually assaulted after she wakes up. Instead, she pushes the man into a zombie that was behind him and escapes. She finds a bird in a staircase she escapes to which helps aid the rest of the group in their escape of the building they're all trapped inside. With the help of a zombie named Carson, O'Keefe, eventually, the group manages to escape the building complex.
