In spite of what Mathias says about it, the sudden sound makes Lucy jump, a startled reaction she's already too uneasy to hold back. To her, it's as eerie as the rest of it, the sound coming from all the way down the mineshaft, with no discernible source. With the way it cuts through the relative quiet, ignoring it is easier said than done, and she finds herself looking in its direction anyway. At this rate, she thinks, they'll be lucky if they don't go crazy before someone else can get to them.

"Something like this has got to be pretty noticeable, right?" she asks, a halfhearted attempt at finding something reassuring about this whole mess. "Even with whatever else is going on, they can't take too long." Even so, she thinks, they ought to be ready in the event that it does, which would be a lot easier if she knew what to be ready for at all.
