there is confusion about all of this
and i wonder if i make this new thread and if its ok
lets start with horcruxes
dumbledore explains in book 6 about horcrux and that voldemort may have created 7 of them
split his soul in 7 parts
1) riddle diary destroyed in book 2 by harry
2) marvolo ring destroyed in book 6 by dumbledore
3) slytherin locket stolen then found and destroyed by ron in book 7
4) helga hufflepuff cup found in gringotts destroyed by hermoine in book 7
5) ravenclaw diadnem found by harry destroyed by fire in book 7
6) i beleive is harry himself which neither voldemort nor harry knew and voldemort kills him actually and destroyin this horcrux which wud explain the force i wud tell later
7) nagini destroyed by neville
then voldemort becomes a mere mortal only as he thought he had elder wand plus he had made 6known horcruxes not knowing abt harry as 7th at all
remember the prophecy
for the dark lord knows not the power he has
meaning voldemort did not know he had transferred lots of his power in harry and in the wand in book 4 where they meet in graveyard and voldemort rises taking harry blood
dumbledore explains this to harry in kingcross chapter that the night the wands clashed some connection happend and harry and voldemort were bound together by destiny in more ways than one
here the wand theory works
the wand chooses the wizard
neither harry nor voldemort knew who was the true master of elder wand when harry went to forest
only after king cross and talkin to dumbledore harry knew he wud survive and he is the master of deathly hollows that includes the wand
he had the stone the cloak and wand allegiance
that is why he did not die.
and that is what dumbledore was counting on though he didnt know wand wud transfer the allegiance but he thought abt the previous wand which harry and voldemort share the twin cores
it was abt wands hallows and mind soul which were connected
that wud be the reason that voldemort wand backfired on him and killed him in the end as his horcruxes also were destroyed
harry only used expelliarmus where as voldemort used avadakedavara
bt the wand wont kill its master and it rebounded on voldemort
there is confusion abt bella and hermoine wand too
i think what happend here was harry put shield charm on hogwarts by standing between the school and voldemort
thats why voldemort spell was not working on anyone and none were hurt
neville was able to break the body binding curse
and silencing charm was also lifting
and 3girls who were fighting bella also not got hurt bcoz of that
and then when bella fell voldy was a lot powerless then he everwas
harry again cast shield charm protecting molly from voldemort
confusion is now what happend to voldemort snape and draco wands in the end
voldemort and snape die
draco wand was in harry hand
but harry repairs his own phoenix wand with elder wand returning the elder wand to dumbledore tomb
anything made sense
sorry i dint put spoiler notice as lots of theories r already open and most may hv read the book
