She did so, tempted to let her wings unfold, to help her float. She did as she was told.

"If you feel yourself sinking, just take a deep breath and hold it for a second, let it out slowly and roll over on your back, just stay there for a second and breath slowly and camly. You will start to float again and then you can roll back over and swim more. You will most likely not sink if you keep your legs moving."
