Harry Potter and associated characters belong to J.K.Rowling and not this very limited writer.
This is just a first (admittedly cheesy) version of this drabble and hopefully I'll get back to it sooner or later. Hopefully it can be improved on.
The two duelists exchanged spells at a incredibly fast speed. Spell after spell were casted, blocked, reflected and or dodged every second. On one side was our hero, the boy-who-lived, Harry Potter ( loud cheering ). In the other was the villian, the one, the only, Voldemort (the audience booed and hissed until Voldemort blocked one spell and uses the killing curse on an audience member in a brief moment. They decided to politely applause instead).
Anyone could see that both duelists were at the top of their game. They were concentating on each other with an intensity that was well, really intense. But it could be seen the Dark Lord was better and our hero was flung to the ground, borrowed wand flying into Voldermort's hand.
He had been informed that Potter had changed wands so he could duel with him without the issue of the brother wands interfering with the duel. It had obviously cost the boy big.
"So Potter, now it has ended and it is time for you to. . ."
A loud beeping interrupted him. The bothersome brat rolled up his sleeve to reveal a muggle wrist watch. "What is that for?"
Potter shivered and shifted as the raven haired boy changed into a redheaded girl. The girl Weasley seemed to be smirking.
"If you are here then where is Potter?"
"Avada Kedavra!" The curse slammed into his back and ended his life with the green flash that he used to end so many other lives. All that could be seen was part of one arm and a wand.
Ginny watched as the rest of Harry appeared as he took off his invisibity cloak. He had a look that she could tell he was almost in disbelief that it was finally over.
She slowly got to her feet and walked to the Man-Who-Killed-Voldemort.
"It's over?"
Harry stared at the corpse as though he expected it to come back to life. It decided not to. "It's over."
