Antonin Dolokhov

He's a Death Eater and served time in Azkaban. You met at a meeting of the Inner Circle, when Lord Voldemort introduced you as his daughter, which was true. He fell in love with you, though he rarely showed it, but he always treated you with warmth. You met secretly a couple of times. During the Hogwarts War, you had already sided with Potter. Now it's after the war, and he's come to your home.
