Meanwhile, Cath squeezes her way out and kills a crawler by crushing it under the rocks. She runs into Greg; they escape from another crawler and find Samantha's body dangling from the ceiling across a chasm. They decide to use her body to swing across the chasm, but are attacked by crawlers again. Greg sacrifices himself to buy time for Cath. Although Cath gets to the other side of the chasm, she attracts a crawler when she breaks down and screams Greg's name, and is killed.
