Harry Potter and the Deathly Hallows
"Do not pity the dead, Harry. Pity the living, and above all, those who must live without love." --Albus Dumbledore
The preface to Harry Potter and the Deathly Hallows, two excerpts that discuss death and living without friends that have passed away, seems to support this quote perfectly. A constant theme in Harry Potter is that there are worse things in life than death; and living without love is one of them.
"I have seen your heart, and it is mine." --the Horcrux
Said to Ron Weasley, Voldemort's Horcrux torments him in an attempt to protect itself before Ron stabs it. This quote also made it into the Deathly Hallows Part 1 movie, and the dramatic scene where Ron is tempted by the Horcrux is one of the most intense in the book/movie.
"The last enemy that shall be destroyed is death." --inscription on the Potters' tombstone
"Where your treasure is, there will your heart be also." --inscription on the Dumbledores' tombstone
Seeing these two tombstones and their inscriptions is an emotional moment for Harry, not least because he can't believe Dumbledore never told him about them. Harry puzzles over the Dumbledores' inscription, but takes the inscription on his family's tombstone as a message about the Deathly Hallows.
"Crookshanks?" Hermione shrieked. "Are you a wizard or not?"
Various scenes in "The Deathly Hallows" recall the trio's adventures in the previous books, including this line and their journey through the tunnel under the Shrieking Shack. In "The Sorcerer's Stone," Harry shouts at Hermione, "There's no wood? Are you a witch or not?" Now Hermione yells the same thing at Ron, who uses his trademark "Wingardium Leviosa" spell from book one to get them past the Whomping Willow.
"NOT MY DAUGHTER, YOU BITCH!" --Mrs. Weasley
This line is memorable for several reasons. First of all, it reveals plump, sweet, motherly Mrs. Weasley's ferocious side as she duels Bellatrix Lestrange --- the deranged, extremely skilled witch described as Voldemort's "best lieutenant." Second, it is one of the only times profanity is used in the series. In the seventh book, Rowling uses mild profanity such as "oh my god," "hell," and "damn," which she had largely stayed away from. The fact that the worst profanity in the series comes from Mrs. Weasley is a surprise, but not an unpleasant one. Mrs. Weasley's line also brings up the recurring theme of parental love and parents protecting children --- in this case, Mrs. Weasley has already lost her son Fred and now defends her only daughter Ginny.
"You are the true master of death, because the true master does not seek to run away from death." --Albus Dumbledore
J.K. Rowling once wrote that after the death of her mother, all the characters in the "Harry Potter" books became defined in some way by death. Dumbledore did not fear death, and in the end neither did Harry --- he would rather die than let his friends die for him. While Voldemort tries to become master of death by conquering and running from death, Harry becomes master of death by accepting it.
"Albus Severus Potter, you are named after two Headmasters of Hogwarts. One of them was a Slytherin and he was the bravest man I knew." --Harry Potter
Harry names his three children James Sirius, Lily Luna, and Albus Severus in memory of his parents, friends, mentors and also Snape, the unsung hero of the series. When Albus confesses his fear of being put in Slytherin, Harry reminds him that one of his namesakes was a Slytherin and that he himself was almost Sorted into Slytherin. It's worth noting that Albus Severus Potter's initials are ASP --- an asp is a type of snake. Perhaps Harry's youngest son will be in Slytherin after all...
