Voldemort going through Harry

[windyroselane]

I saw Voldemort flying through Harry as a last ditch effort by 
Voldemort to attach himself to a human with the Stone. Quirrel was 
gone. Harry picked up the stone. At that moment that is what
Voldemort required most: a human with the Stone in his hand. Only his 
attempt at inhabiting Harry, however temporarily to use the Stone, 
failed since Harry did not want to use the Stone or give it to him.
It was, in effect, a Wizard's duel without the wands. Hence, the 
intense duel of wills knocked Harry completely unconscious, Voldemort 
was weakened yet again, and Harry woke up much later in hospital.
With wands we would have had a similar scene, but much closer in
effect to that which takes place near the end of 'Goblet of Fire' 
where Voldemort is back full force and both wizards are strong 
enough to concentrate their will down through their arms and out
their wands.
