Antipode - A direct or exact opposite.
They were complete opposites. One was dark, fanatically proud and the Wizarding World's most wanted woman. The other was fair-haired, fair-skinned and fair-minded; sister in law to Harry Potter's best friend. If anyone had known of their illicit meetings, no one would have known what had driven them together.
Nor did they. But driven they were. They never missed an assignation. Never. They would have rather died.
Some would have said they were mad. Others that they enjoyed the thrill of courting danger. But Bellatrix Lestrange nee Black and Fleur Weasley nee Delacour preferred to think of themselves as special.
