That is exactly what I thought I mean they did not do any oral spells they were always just pointing and a spell comes out. All except obliviate, that is. Which means they are masters at nonverbal spells!
I know this is supposed to be a mean girls reference but I Don't know if it's just me but I like the ending in the book alot more. When Harry repairs his wand then puts the elder wand back in Dumbledore s tomb.
