Water is the Fourth Element (the Fifth being Spirit, which combines them all), and supposedly the Element of Mystery, Intuition, Psychic Abilities, Emotion, and Magick as well as lunar and feminine energies. Alongside Earth the First Element, it is a female one.
Erin Bates has an affinity for water, and her loyal but sometimes highly emotional -- so much that she ceases to feel -- portrays Water's potential.
The moon rises the tides of the Sea. Henceforth their connection, and the Element's deep affinity with Nyx (the Night Goddess).
Water always ends up being the final element; the Celts' had Land, Sky, and Sea, and the Wiccans have - usually - Earth, Fire, Air, Water, and sometimes Spirit.
