In the crucifix scene, Cassie enters an abandoned gas station she goes to time to time for supplies. As she walks through the busted out door she automatically realizes something is different about the place. "...I listened to the silence of the abandoned store...And then Something made a noise..." (Yancey 8). She came across a dying soldier who was holding something metallic in his hand, and as soon as Cassie saw the shiny object she killed him. The object was "thin and metallic, and my finger yanked back on the trigger, and the rifle kicked against my shoulder hard,...as i emptied the clip...i heard something screaming...it wasn't him screaming, it was me screaming..." (Yancey 13) After killing the man Cassie went to his dead body to see that he had been holding a crucifix. This scene shows how the apocalypse is getting into Cassie's head and making her shoot first and ask questions later. This scene was a major development of Cassie in the movie and the novel, for it shows how her humanity is slipping away.
