"You're kidding me," Viola says as she looks at the problem in front of her, and then she looks back to her comrades, "be ready for them to show up, because I'm pretty sure this is going to make noise."<br/><br/>She reaches for her shield, and sees if she can't slowly scrape the caltrops on the right side of the hall to the left.  It'll be slower than walking across, surely, but one of them screaming in agony when they step on a caltrop (and then a few more in the panic of trying to make the pain stop) will wake the dead.
