Priori Incantatem, and Harry's brand of Magic

[Scott]

No: HPFGUIDX 1543

There seems to have been a lot of new theories on the reverse order 
lately (or at least more posts on the matter). I thought the one 
about polyjuice was interesting but I don't buy it (no offence).  I 
have to agree w/ Penny that the Potters didn't know what was coming. 
I also argree with Penny in that Harry himself made his father come 
first.  After all it was only by Harry's will that ANYTHING came out 
of Voldemort's wand, if V. had had the stronger will Harry's wand 
would have been the wand spitting up spells, right?

???-Another question that this brings up is if Harry had been able to 
force EVERY spell from V's wand what would have happened...I sort of 
thought that the wand would explode and that could have killed 
Voldemort as well.  Any ideas of what else might of happened?

Last of all there is Harry's own brand of magic, i.e. Blowing up Aunt 
Marge, making V's and regurgitate spells, the disappearing glass of 
the boa's cage etc....So can most wizards do this type of spontaneous 
magic?  I don't remember any specific evidence though there may be 
some (small wizards that don't need wands, did we see this in GoF?) 
of these that we don't know and that I simply can't remember and am 
to lazy to search for examples...

Well now, comments?
