At the sound of a howl, Jadna's first instinct is that she's hearing a wolf... She spins, looking for it-- then, realizing that seeing it wouldn't keep it from tearing her apart, she snaps her attention to the wall.  It takes less than a second to realize just how slick that wall will be where the water's coming down... probably ripe with lichens and worn smooth... "Shit..." she hisses softly, pawing at the water... just in case there's a grate, or a crack... assuming there's not, she's prepared to run... "we must get away from here..!"
