Antonin smiled thinly, "When I first met Morag, she was a dangerous woman. Now, be it with magic, weapons, or her bare hands, she is deadly. The only way anybody could keep Morag against her will would be unconscious. Then, we each are half of a portkey, keyed to the other. One of us can always find the other."
"I'm afraid trying to use her against me would be a most unpleasant experience for someone. If she didn't kill them, I would, slowly, several times. Probably with all of their family, friends, and pets. If someone were to try to use me against her, she would do the same, and dig up their dead ancestors and kill them, too."
Now Antonin did give Pansy a real smile. "She's been seen at enough of our little battles now that I'm not outing her. She's far from the little clerk everybody thought she was. And I do love her."
He grinned, "But as I told you before, we're a bit more open about the flirting and playing then some couples."
