Oh, dear Gods. It’s a fiction book about people who work with magic. The headaches appear when the villain is nearby. The headaches are a magical warning, since they are linked to the scar. Repeat after me. It’s a fictional book with magical energies abounding. It has nothing to do with genetics. It’s not a health issue. Please focus on real science.

ok, like you said, its a fictional book, who cares if he has migraines or not...the 'migraines' go along with the book...when he has one, voldemort is around

Some people seem determined to take all the fun out of life. Is the New England Center for Headache a government agency? Somebody has money and time to waste.

A way to get the agency to pay for the books so they have some free reading
