Harry Potter approaches Voldemort in the Great Hall with great apprehension and fear for himself and all around him; but he must finish him off.
"Harry Potter, you are alive," Voldemort sneers, "well no matter, I will finish you off now."
And with that, he starts swiping and sweeping his wand at the little boy (in relation to him) who tries ducking and sweeping around the spells and is succeeding. He runs behind a little indent in the wall, to get his breath back and prepare to send out the strongest shield charm he ever had: he ran around, hoping to take Voldemort by surprise, but he wasn't. he flicked and flicked, and Harry's shield was getting weaker and weaker: he needed to renew it but that would tale 2 secods he didn't have, so he relied on his running and the occasional offensive charm shot at Voldemort to carry him through.
And for a while, it is enough. Then Harry Potter is out of luck.
He turns a corner in his running, and the shield falls away. Voldemort blasts his wand out of his hand, and forces Harry into a kneeling position, before placing his wand in the crook of his neck, and saying the magic words, "avada kedavra" at the top of his voice, to make a jet of green light burst out, and make Harry Potter fall to the ground in a crumpled heap.
All at once, his fighters broke forwards; and Voldemort begins taking swipes at them, sending killing curses left, right and centre, but none held. Harry Potter has died for them, and they recognise this, and begin fighting so Harry didn't die in vain: they attacked Death Eaters, killing a load then a huge crowd took on Voldemort, all shooting Killing curses at him, so many he doesn't have a chance. Yet the curse came from a body on the floor so, who could it be? Voldemort died.
Then everybody, instead of rejoicing, go and stand around Harry Potter's body, lying limp and lifeless on the ground, until he sat up and says:
"They fell for it! He's dead! Thanks everybody for holding him off so I could get him from underneath – he's gone!"
The crowd, stunned for a moment at the revival of a dead man, then they scream and shout to congratulate him: all besides his best friends Ron and Hermione who are currently residing in the little annex where all the dead bodies are because they died from a curse that Voldemort shot at them.
"Harry!" Ron and Hermione shout – he hadn't killed them either!
Harry Potter wakes up with a bang, and he finds himself in bed with Hermione – it was all a dream!
