"There was just one woman hiding there already and she was just silently crying, sitting next to me, and that was really, really chilling because she wasn't even in panic.
"She was kind of almost already in grief of, you know, things were going to end. It was a total resignation or something, and that really freaked me out more than if she had been you know crying or screaming loudly."
