The smell is really pungent this far in, and Shepard can't help but wrinkle her nose a bit as they move forward. They're in what seems to be a very intricate, maze-like setup, but she dutifully follows her companions, careful to stay within their footprints (though the turtle's are a bit different shape than a human's).

After a while, though, there's less muck underfoot, and the smell starts fading a bit. It's kind of a relief. "Any change up there?" she asks, her voice little more than a whisper.
