I watching all the Harry Potter films in a row the other day and a few things really confused me. Why, in deathly hallows part 2, when Hermionie is Bellatrix can't they show the goblin Bellatrix's wand when harry took it from Draco at Malfoy Manor? And Avadra Kederva is illegal, so why, in the goblet of fire, does "Mad Eye" use it to kill the spider thing, or is it only illegal to use it on animals, and I know it wasn't really Mad Eye. There's ghosts in Harry Potter, like Moning Mrytele and St. Nicholas, so why don't Harry's parents and Dumbledoor and Mad Eye come back as ghosts? Maybe I'm just paying way too much attention lol. Thanks :)
