"That's the Lightning Attraction Charm from the Weather Charm! No wonder Graves used the Water-Making Spell! He was creating the conditions for the Weather Charm! Looks like he learned from the First Task!"
Seeing this, a faint smile appeared at the corner of Seraphina Piqueri's lips.
"Wait! Why are there flames again?" She noticed the anomaly in the Image Projection Screen once more. "If he wants to use the Lightning Attraction Charm, then he can't use flames as well..."
"This shouldn't be Graves casting the spell..." Seeing Dumbledore nod at her, she sounded even more certain. "Then it must be Potter casting the spell!"
"The flames are closing in on that cloud! They're getting closer and closer! The cloud has been scattered by the flames! Merlin's beard! How did Potter ever think of that?"
"He actually saw through Graves's Lightning Attraction Charm! That was incredibly clever! But the smoke still hasn't cleared... What's happening inside?"
Seeing the cloud blasted apart by the flames, Seraphina Piqueri pressed her lips together, her brows knitting tightly.
Just then, a red glow appeared in the gray mist. Vizet, who was serving as the Referee, also raised his Wand and completely dispersed the gray mist.
Charles Graves and Harry appeared. Charles Graves stood there in a strange posture, his hands empty.
Harry wore a triumphant smile and raised his left hand high. Charles Graves's Wand was clutched in it.
Ludo Bagman relayed Dumbledore's explanation: "What a clever method! Potter conjured glue to trap Graves, then used the Disarming Charm to win the duel!"
