"Can we not torch them like before?" Alan asked, being fed up with that noise. It was loud and even got on Mark's head, never mind Alan who had even more sensitive hearing than Mark.
"Airflow would not allow that. When we get out, I'll burn the rest of it inside" hopefully it will be soon.
"How much further do we need to go? I think I can hear them buzzing inside my ears" Mark was not sure how much he was hallucinating or if there were actually monsters inside the vent with them.
"Don't worry. They are not inside here with us. Yet" the yet was very much pronounced in that sentence. It would be a problem for them once these monsters found a way inside these vents. They had to get moving on and they had to find the external vent.
