So what do I think about the WORDS that came from Harry Potter in the story, well I think that if anyone else had met Harry in Kings Cross, then I don’t think Harry would have gotten “on” to go back to the forbidden forest to continue to fight and defeat Voldemort. Before this scene, Harry is met by all his loved ones who have died, giving him encouragement about death and letting him know that they will be there with him at the very end and through always. Then after dying meets his old professor who says, “I’ve always praised myself on my ability to turn a phrase. Words are in my not so humble opinion an inexhaustible source of magic, capable of both implicating injury and remedying it.”, and “Help will always be given at Hogwarts to those who ask for it” however rephrases it to say “Help will always be given at Hogwarts to those who deserve it” Dumbledore then ends by saying just because everything is happening in Harry’s head that doesn’t mean that it isn’t real. All this words lead up to Harry returning, killing Voldemort and continuing a wonderful life. Now all this words meant something, but what I do think is if the words were said by someone else, there may have been a different outcome. Say if Lilly Potter, his mother, met him there and even said the exact same things, well maybe the words would have influenced him to just pass on because he never had that opportunity to spend time with his mother invoking an emotion to be with her a leave the others behind. However say for instance, Serious Black , his Godfather, met him there and said the exact same things, well in my own weird theory, I think he would have gone back, since he had that opportunity to spend time with Serious, he was able to at least get to know him a bit, and now Serious is giving him all this advice, well Harry may have felt prepared enough to go back and fight once more.
Now all of this to say I think words and word aversion may have something to do with the person who they are coming from. I think when things are said by a specific person, it allows us to process it though the heart of that person because we understand where they are coming from and the heart behind it.
