Okay, I need to take this opportunity to clear something up. Geminis are not twins of good and evil, and they are not two-faced. Geminis are based on the warrior twins Castor and Pollux. Castor was mortal, but Pollux was immortal. Eventually Pollux realized that his brother would die and begged Zeus to make him mortal and let him die with his brother. Zeus compromised, and said from then on the twins must be apart; each would spend half of eternity in Hades and half of eternity on Mount Olympus. Gemini reflects this duality; sometimes mortal Castor, concerned with the material world, and sometimes immortal Pollux, concerned with the spiritual realm. Ahhhhh..... I feel better now ^^.
