Here we have two dual signs, giving us a total of four personalities to interact with each other. One side of Pisces is optimistic, brimming with ideas, while the other side is secretive and irrational. Gemini is also moody and changeable. Gemini may fall in love with only one side of Pisces, and the other side of the Pisces personality could come as a shock to Gemini as it is not something that they may have been prepared for.
Pisces is possessive and clinging and hates Gemini's unpredictability and lack of consideration, whilst Gemini can't stand Pisces's emotionalism and dreaminess and just wants to have fun. Emotional Pisces is too easily hurt by thoughtless Gemini, who thinks they are just being mischievous and playful, but Pisces is sensitive and takes things to heart.
Each practices deception in his or her own way - Gemini evades, Pisces won't deal with reality. In different ways, each is as shifting and changeable as the other. Pisces lacks direction while Gemini goes off in too many directions. This is not a happy match, and both signs need more dominant partners.
