The Two of Cups shows the princess of Ys sneaking out to the dock by night. Her reflection, holding the key to the gates, foreshadows the downfall of the city. The bell dropped into the sea is a covenant with this shadow-self. This card is about alliances, especially secret ones, and more generally things that are suppressed and hidden. It can signify a fateful meeting with another, or a look at one’s own reflection.
This card links to the Nine of Cups, where the vision in the water comes to pass.
