Gemini's Dark Twin

I am getting quite addicted to answering search engine questions, and the greater public have become my source of inspiration. I feel like a fisherman pooling through my queries. I had a question about “Why Gemini are the abusers of the Zodiac” and I wondered why this question concerned Gemini. The more I thought on it, the connection may have something to do with the good and evil twin. 

Dr Jekyll and Mr Hyde and the strange case of the split personality. I will have to discuss the dark twin in relation to Gemini as it's the only link for the question I can find. All double sign personalities are centered upon the light and dark aspects of the personality/dual experiences/two natures, the other double bodied signs are Sagittarius and Pisces. The duality of human nature with both good and evil existing in us all is the main point of stories like Jekyll and Hyde. And if we can't accept our darker side it is often projected outside, or we try to hide our repressed side, it's the part of us we don‘t want others to see...

The best movie I can think of which archetypes Gemini is: The Man in the Iron Mask. The evil Twin hides his brother in a dungeon and keeps his face hidden behind a mask, the twin is trapped in a state of darkness, unable to see the light and achieve consciousness. Therefore one twin is unable to express himself, and the weight of the iron mask represents his own mortality, heaviness and bitter cynicism. The other twin lives his life as a King and has a godlike divine existence. The king does many crafty things throughout the film. For example, to win the woman he wants to marry, he doesn’t get rid of her partner personally, he sneakily sends him off to war, knowing he would be killed. The devious mind of the king are revealed and he is unmasked. The twins exchange places, and one lives in darkness and the other in the light. The two are never together in one place and this is part of the myth of Caster and Pollux, the mortal and divine twin.

I don’t have a deep understanding of myth but movies can connect us to our own astrological myths and dilemmas. The twins represent the stark opposite nature of dark and light. One twin seeks to destroy the other and they live out opposing sides. Sibling rivalry comes from many of the twin myths with one brother attempting to kill/repress the other. However, both need to be brought into consciousness and somehow integrated into the personality. Gemini hates to be trapped by the weight of his own mortality. The duality and dark/mortal side of Gemini has to do with the fact that this is a double sign. The shadow side pertains to all human beings, and we all have our own dark/repressed natures. The hidden self is locked away but desperately wants consciousness.
