Oh, that sounds like it would work! Perhaps its one of her fist patrols, or a test patrol? Or, the others were sent out, and she was one of the few left?
And, I would assume it depends o the soul, to a degree. At best, everything is crystal clear, but cold and makes them feel hallow, and at worst, a pixellated, sharp haze, painful almost physically or otherwise accessible. They will retain what their body was trained to do, and other basic skills, though they won't remember how (if their soul represses their memories too much)- Much like we are, with learning to walk and talk.
