Fair enough. “Looks cool” trumps “makes sense”, at least to moviemakers.
Yes, as I said, this wand allegiance thing is a giant ass pull on the part of Rowling. She didn’t think it up until book 7 because she wanted a means of subverting the power of the Elder Wand, so she could put the most powerful wand in the hands of the most powerful and evil Wizard and have Harry win. He wins because the EW likes him better.
Someone mentioned the sword showing up vs Neville having the sword hidden in the Sorting Hat. When Neville finds the Hat, he is looking it over and sees something shiny in it. That is the Sword. He was then waiting for the right time to pull it. It didn’t come to him at the moment he pulled it, but at the moment he picked up the Sorting Hat.
As previously quoted, yes all Wands are subject to changing allegiances. Don’t look behind the curtain, there’s just an old man there, nothing important.
I thought Harry was just being a dick about liking Malfoy’s wand better, but then he didn’t fix his old wand (that we saw), so…?
