On the edge and breathing thanks to a couple of small balloons while hogtied. Casey Calvert is extremely thankful at this point her captor has not gone completely mad. She holds onto life by her shallow breathing. If she exhales too much air, she will go plummeting to the bottom with now way to get back to the surface. Her hogtie is just so that she is inches from the bottom, so one slip would mean disaster. Would hate to see her with only an inch of water separating her mouth and o2.
