Eino didn't have any allergies, at least none that he was aware of, but apparently it was possible he could develop them. That wasn't very reassuring, what if he was allergic to something he really liked, like dragons or thoughts? What if squibs were allergic to magic? Hmm, that was a good theory worth looking into. "Allergy..." He began with his hand high in the air. "Is when your body doesn't like something so it swells and boils in response to it, to reject it. If you don't heed the body's warning, it could be very dangerous. Very clever the body is." Eino wished everything would respond so cleverly to things they didn't like. It was awfully confusing receiving vague messages in the case of people.
