Gemini isn't only linked to astrology although that is what it's most famour for. Ancient Pagan Romans used to think the rare twins shared a soul. Each with an equal half. I've decided to up that. And make it that if the universe deems it so. That gemini are born and breath to life the exact same second. If a twin is born first or second, then they are just twins not gemini. Gemini are born at the exact same time, no milisecond difference.
