The Queen of Cups is focused on emotions and emotional matters. She has a gentle, receptive and passive nature and she can be a great helper, healer and counselor. Ill-dignified, the Queen of Cups is the personification of the drama queen. The King of Cups foretells that emotions, relationships, matters of the heart will be in the foreground. If not ill-dignified, the King of Cups indicates that we have the experience and the maturity to deal with emotional matters efficiently. In his negative manifestation, the King of Cups can become, cold, manipulative, cruel. The Queen of Cups/King of Cups combination is focusing on emotional expression.
The elements of the cards are Water (Queen of Cups) and Water (King of Cups). This combination is a passive one. Passivity or inertia prevents a situation from changing. That is why we should not expect major shifts when two Water cards appear together in a sprea. The energies remain static, for good or ill.
