So I was like a month off. I had thought Pisces at first and then Cancer, but he's a Gemini.
Gemini is the third sign of the zodiac and has influence over the hands, arms, shoulders, and lungs. Positive traits include quick wits, versatility, flexibility, fluency with words and ideas, an open mind, a love of learning, adaptability, agility, sharp perception, and cheerfulness; negative traits are duplicity, mood swings, flightiness, nervousness, fidgeting, lack of attention span, a tendency to be easily influenced, and undependability.
Ever heard the phrase "snake-tongued?" It must have been invented to describe a Slytherin Gemini. (This doesn't refer to the Parseltongue gift, either, although the few Slytherin wizards who exhibited it have had a disproportionate number of Geminis in their midst.) Slytherin Geminis have the dubious gift of being able to lay the blarney on thick, and be believed. This is due to both their imaginative mental agility and to their skill with words. Of course, not all Slytherin Geminis are liars - but it is probably advisable to get all sides of the story if you hear interesting gossip from one of these wizards. Slytherins born under the sign of Gemini are also naturally skilled at any magical work which involves sleight of hand or incantations. They are less determined and aggressive than the average Slytherin, though, save perhaps in a field that involves debate. You will find far more of them chatting in the common room or looking up arcane lore in the library than on the Quidditch field or in a dueling match, with the exception of Quidditch Seekers: the sharp eyesight and quick reflexes associated with Gemini are good traits for a Seeker to have.
