Good quiz, I would just question hedwig dying to 'save Harry', he died in a misdirected spell, and if accepted I would argue that Dumbledore also deserves to be here. Another person who souldbe here is Mad-eye Moody
just wondering if pettigrew could be considered as dying to save harry indirectly? he hesitated when going to kill harry, resulting in him choking himself - so then harry and ron escape.
