muggle: That gave Harry and Hermione just enought time to recover from the shock. They both grabbed their wands and cried AVADA KEDAVRA!!! then Voldemort died and Harry and Hermione were happy... but then! Harry had the last Horcrux inside him and he turned into Voldemort! So Hermione knew that the only thing to do would be to kill Harry... so she did. But since Harry had tuned into Voldemort, she was really only killing Voldemort and after she killed him, then Harry came back to life.
