Derrick looked out into the hall as it opened, and shortly slipped into the dark corridor. He couldn't see very much, so Derrick waited for the others, so that he could also giving his eyes time to adjust. As he stood, he noticed a faint odd noise that seemed to be coming up ahead. He edged out into the hall to try and hear it better, noting that it was somewhat close.

It was a fairly strange noise, somewhat unfamiliar to Derrick. Try as he might, he couldn't really identify it. He turned to see if the rest of the team had come through yet. When they neared his position, he whispered quietly to them.
"Do you hear that?" Derrick said, keeping his voice low.
