"It’s been a decent effort, Antonin," Harry nodded appraisingly as he stalked ever closer to his prey. "Don’t feel bad that you haven’t made much of a dent in me. Well, you've given me one or two ... which my wife will be very cross with me for allowing ... but she knows some good magical Reiki for that. But I’ll let you in on a little secret, Antonin. You see, you haven’t just been fighting my power tonight ... even though I’d have beaten you with only that anyway ... but I married my Hermione in a very special wedding ceremony. So now, our powers are fused as one. She empowers me, our magic combines into a single energy of ridiculous intensity and it hugely overpowers my spells ... a bit like this."
