Newly arrived water-gardening expert Chastity has already bound herself to the waters of the estate by bathing in a wedding dress, and had a thorough soaking in her working rig of denim dungarees and jacket, but to symbolise that her work involves caring for the water gardens as well as maintaining them, Nurse Wendy introduces Chastity to the joys of uniformed river bathing.
Of course all of Nurse Wendy's therapies tend to be reciprocal and hands-on, so she willingly takes her turn under the watering can first, allowing Chastity to thoroughly wet her green uniform, and even pour buckets of water over her head, before taking charge and throroughly drenching Chastity in her uniform dress in return.
