Characters and Plot: One of the main characters of this story is the antagonist himself Harry Potter I feel like he is the most who changes from the beginning to the end. He was just kid living with his mean uncle and Auntie and annoying cousin. And he could not really do anything without them getting on his case and they'd leave him when they did something fun. But when Hagrid had came and opened to whole new world literally of magic. Now we start to see this scared shy kid become more adventurous and courageous through his time at Hogwarts. And we also see another character change in most of the characters in general because they think that this boy is supposed be like as good as his parents were in reality he was just now starting magic so they are a little disappointed, but later on in the series harry fulfills their expectations.
Important Themes and Symbols: I can see how friend ship would be the theme of Harry Potter and the Sorcerers Stone. Through out the whole story Ron and Hermoine have been their for Harry through his time in Hogwarts helping him keep the Sorcerers stone away from Voldemort's hands so he can use it to become the most powerful wizard without them he more than likely would have got the Sorcerer stone. Another friend of Harry's Is Rubeus Hagrid the one who saved him from his miserable life with his uncle and auntie. Harry felt so close to him instantly and he has been their for Harry and teaching him the way of the Wizard and protecting him from anyone who tries to hurt him, and he is also the one introduced and got him ready for Hogwarts took him shopping for the necessary stuff that he needs for Hogwarts. So that is how I can see the theme of Harry Potter Sorcerers Stone would be Friend ship.
