Meredith's head snaps up in the direction of the sound, something staggeringly loud, bloodcurdling and impossible to place. "What is that?" she demands. "What's happening?" She wouldn't expect an answer even if it looked like anyone out there knew any better than she does, but she still wants one, shaking the bars and stepping quickly back in the next instant as one of the guards advances. It's not a sound she knows, one more unfamiliar thing in a sea of them, but more immediately concerning, if only because no one else seems to know what to make of it either. If she had a little more time, maybe she could use that to her advantage, but she's too distracted to figure out how.
