As someone who was raised on the books first before the movies, I take issue with the "Malfoid and Harry holding the wand together" concept, and it's the one thing I hate most about the movie. For the sake of an "epic, cinematic final battle", Yates turned what was an emotional fight and intense payoff into just another moving setpiece. For those who don't know, the way it played out in the books was that nobody knew Harry was still alive, yet they fought anyway. Harry himself escaped Hagrid's arms in a moment of confusion, and spent most of the battle hiding under the invisibility cloak (thus solidifying his connection to the "wisest" of the Deathly Hallows, and the third brother, Ignotus) and firing nonverbal protective charms at his allies. It is not until Molly Weasley destroys Bellatrix Lestrange, Voldemort's top lieutenant and the closest he has to anything like a consort, and in retaliation he prepares a deadly curse to hurl at Molly, that Harry reveals himself with an exceptionally powerful protego. Harry then launches into an entire explanation of why he'd accepted death, why Voldemort could never comprehend it, why none of the Death Eaters' curses seemed to be hitting their marks any more, and why and how Harry himself came to be the master of the Elder Wand. There was no battle of wills, there was no "DBZ ki-blast struggle", as I call it. Instead, there was a resurgence of hope within a bitter, hopeless battle. There was a final showdown, with Harry and Voldemort circling each other, and with Voldemort's defeat only the only logical outcome precisely due to his failure to understand (or perhaps willful ignorance of the fact) that the loyalty of the Elder Wand could be decided by a struggle with someone he likely saw as one of the weakest of his followers. Voldemort's curse rebounded instantly, killing him. I know you all like the idea of "the power of love" defeating Voldemort. And indeed, it makes sense, in a way: if ever there was a magic that could - and had already - defeat him, that would be it. But it is based on a scene in the movie that I don't hold to be canon, and one I will never accept. I don't know where Malfoid would fit into that, but I'd like to think she's certainly among the onlookers as Harry explains to Tom why his wand won't obey him.
