Harry Potter and the half blood prince

Harry had to get that lost memory from Slughorn but still doesn't know how he is going to do that. So Hermione suggests that he use the lucky potion called Felix Felics. Then he gets a letter from Hadgird saying that Argog the spider died. Hermione and Ron said that they weren't going but due to the potion, Harry decided to go. Ron told him he was insane but Harry knew that it was only right to come for Hadgrid. So Harry set off thru the castels door to the hut. Once outside Harry saw Professer Slughorn and told him about the spiders burial. Professeer said he would get some drinks so they would be able to drink to Argog. When they get back in the hut, Harry knew exactly how he was going to get that memory from Slughorn. Harry started to talk about how Voldemort had had no remorse when he killed Harry's mother and father. Slughorn began to cry and Harry knew he was in he told him that if he didn't have that memory he wouldn't be able to save the wizards and witches from Voldemort. Eventually Slughorn gave Harry the memory and Harry went to see Dumbledore and Dumbledore was most excitedd to see Harry had got the memory. They looked at the memory through the Pensieve. It unlocked many secrets to Voldemorts powers and how to kill him. Harry knew, that as the chosen one, it is his oblagation to protect everyone and if killing Voldemort was how he had to do it thenn so be it. The profecy stated that one cannot live while the other dies. Harry knew who would live and who die. It was all in the matter of time.......
