I AM SO CONFUSED!!! I just finished "Deathly Hallows" and there are so
many wands in this story I can't keep track. I understand that
Voldemort stole the Elder Wand from Dumbledore's tomb and I think I
understand why it won't work for him. But what I don't get is that in
the final battle Harry says that he stole the Elder Wand from Draco
and that that makes him the master of it, but at the same time he is
holding another wand which he says he stole from Draco. I just do not
understand. Please explain. Thanks.
