Harry Potter and the Deathly Hallows is the seventh and final installment of the Harry Potter series, published with great fanfare on July 21, 2007.Harry's not going to school this year, but don't worry, it's for a good cause. Harry, Ron and Hermione's only hope to defeat Voldemort is destroying all his Horcruxes as he infiltrates the Ministry. Harry, eager to get started on his hunt for horcruxes gets slammed by Voldemort's quick overthrow of the wizarding world, forcing the trio into hiding, where they must contend with themselves, who they are, what they are doing, feelings of helplessness, and if they really knew Dumbledore.Also, remember how the previous few books just had one person die at the end? This time no one is safe at any point in the story. Rowling had warned in interviews that book 7 would be a bloodbath, and wasn't kidding.
Tropes exclusive to this book or at least especially prominent:
Played with. Neville becomes a freedom fighter and a damn good one. He even destroys Voldemort's final Horcrux. However, fans who were expecting to see a showdown between him and Bellatrix due to the buildup from book four onward were left disappointed, as Molly Weasley ends up being the one to fight her. See Berserk Button below.
J.K. Rowling later ended up explaining why several characters die offscreen, point out that battles are battles and people do not die whenever the story finds it convenient. Presumably, Bellatrix gets offed by Molly because that was how that part of the battle ended up (Neville kicking ass and taking names elsewhere). Things do happen that way in real combat.
A What Could Have Been. Florean Fortescue's disappearance/kidnapping in Half-Blood Prince. Rowling has said that this was to involve a subplot of Fortescue and the Elder Wand. Rowling cut it after realizing it went nowhere. She made this revelation in response to a question about Fortescue's disappearance in which she said he was indeed unfortunately dead and explained the dropped subplot.
When Hermione has to erase all of her parents' memories of herself so Voldemort can't torture them for information. It gives a parent a sense of failure to protect their child, that they're weak and powerless.
It's very easy to see why Molly Weasley goes full Mama Bear during the Battle of Hogwarts. "Not my daughter, you BITCH!", indeed. After all, we saw her boggart in the fifth book — her family dead. She lost her two brothers in the last war, one of the Weasley twins has just died, and the daughter she so desperately wanted after having several sons is apparently the next one...
A Nazi by Any Other Name: The Power Trio are on the run in one of the most blatant parallels of Nazi-occupied Europe ever seen. The Ministry of Magic has become so corrupted from the inside by Les Collaborateurs, that they essentially pass the Nuremberg Laws against Muggle-born wizards, and under the guidance of Umbridge are shown creating pamphlets touting purity of blood whose content and saccharine covers call to mind the publications of Julius Streicher. The various Death Eater minions inside the Ministry are dressed in khaki clothes, with red, white, and black armbands bearing the Dark Mark. The sign of the Deathly Hallows has a history very similar to that of the swastika, as well - originally an innocent symbol, then used by wizard-supremacist Grindelwald, etched on walls by stupid pricks to get attention...
Polish translation of explicitly called those who hunted muggleborns and La Résistance for profit szmalcownicy. Real Lifeszmalcownicy sold hiding Jews to the Nazis during The War.
Said Snatchers can also be compared to the Einsatzgruppen that hunted Jews, inter alia, in occupied Europe.
And I Must Scream: Voldemort's final fate according to Word Of God, as previewed in "King's Cross". He is in the boundary of life and death, never dying, but never living at the same time.
Some fans feel that the final confrontation between Harry and Lord Voldemort was a bit of a let-down. Voldemort casts the Killing Curse at Harry with the Elder Wand, but since Harry is its true master, the curse backfires and kills Voldemort. From a storytelling point of view, the true climax of the novel was when Voldemort "killed" Harry in the forest (and sealed his own fate), everything after that was denouement, but Voldemort (and the readers, the first time through) did not know that.
Averted in the film, however, where Harry and Voldemort have a duel for five minutes, with Voldemort flying around all over Hogwarts and Harry holding on for dear life. Then their wands induce a Priori Incantatem-likeBeam-O-War, and they duel for almost a minute before Neville cuts Nagini in two, which causes Voldemort to disintegrate due to all the Horcruxes being destroyed and his strength weakening to the point where his killing curse slowly rebounds on him. However other fans felt this deviated too much from the events in the book.
Anti-Villain: The Malfoys. At this point, the only thing they want is for the family to survive together. In fact, the moment they learned that Draco is still alive, they take the opportunity to lie to Voldemort about Harry's fate.
Anyone Can Die: If you were really attached to certain characters, you're gonna need some tissues for this one.
In the book, Lavender is attacked by Fenrir in the Battle of Hogwarts, but is saved in the nick of time by Hermione. In the film, Hermione sees Fenrir over Lavender and he runs off, but then we see it's too late; Lavender lies dead on the floor, eyes unfocused and dull. Word Of God and a later published book to go with the series confirm her death.
Pius Thicknesse got cursed in the face and fell off a battlement in the book, but survived the battle and was forgiven because of the Imperius Curse he was under (courtesy of Yaxley). In the film, Pius was killed by Voldemort in a bout of rage when Ravenclaw's diadem was destroyed.
Even HARRY wasn't immune to this. Potter fans enjoy hearing folks who didn't read the series saying things like "It's not like she's going to kill Harry, the book's named after him!"
Regulus Black was also The Atoner, although he is dead before the book begins.
The Malfoy family, and Draco in particular, play with this trope. Draco legitimately regrets joining up with the Death Eaters and his role in Dumbledore's death, but he never actively tries to redeem himself, partly because he's in too deep and partly just because of a lack of character. In the end he settles for what might be called passive resistance.
For instance, his plan to save Harry from the killing curse involved: Voldemort's horcrux absorbing some of the impact, Harry's blood being used in Voldemort's resurrection, having Voldemort himself cast the curse, making sure the elder wand was not fully under Voldemort's control and finally by having Harry willingly sacrifice himself rather than continue to fight.
The part about the wand being under Draco Malfoy's control was specifically not in Dumbledore's plan, but in the end actually works to Harry's benefit. In Dumbledore's plan Snape would have killed him without Malfoy getting involved at all. This would have prevented Voldemort (or anyone else) from obtaining the Elder Wand's full power as it would not been won in a duel. Though things do end up working out even better than he could have imagined.
In case you didn't notice in any of the previous 6 books, Harry growing up with no parents is a bit of a sore point with him. Lupin and Ron both set him off for nearly abandoning his unborn son and saying that Harry doesn't have to worry about his parents in danger, respectively.
In a backstory, it is revealed that Percival, Albus Dumbledore's father, found out that his daughter Ariana had been assaulted by three Muggle boys who saw her using magic and he went and attacked them himself. He ended up in Azkaban for it, but he never revealed his reasons because the incident had driven Ariana half-insane and she would have been permanently confined in St. Mungo's Hospital.
Voldemort had a couple of them, most notably when he found out the the trio stole the Hufflepuff Cup from Gringotts. He killed the goblin who brought him the message and anyone else who was around and couldn't get away fast enough.
An overlooked reaction was Harry to seeing Ginny almost killed by Bellatrix. Originally going after Voldemort, he changed direction upon seeing that, but was passed by Molly, described above.
Ron definitely found Hermione's after he ran out on her and Harry. Upon coming back, she physically attacked him before demanding her wand from Harry.
Beware the Nice Ones: Andromeda Tonks is terribly offended when Harry confuses her for Bellatrix. Now... remember whom her sister's are? Her elder sister is (in the words of Word Of God) the "Death Eater per excellence" and the other is a mother who lies to the Dark Lord to save her son. Yeah — Andromeda comes from a family that were born with titanium balls. Don't fuck this woman off!
Harry himself. Even though he does not exactly lead anyone, he continues to inspire hope and is a rallying point for the students of Hogwarts, Dumbledore's Army, and the Order of the Phoenix. In the practical sense, however, Moody and, after he dies, Kingsley, seem to be Dumbledore's designated successors.
Off-screen, Neville is this for Hogwarts during Deathly Hallows: it's implied by the way he talked that he stood up and took a lot of crap so the other students wouldn't have to, he was the only leader of the DA to remain at school for the entire year, and during the Second Battle of Hogwarts, he was explicitly shown leading an attempt to kill Death Eaters en masse using Mandrakes.
McGonagall also serves as a Big Good at Hogwarts in Dumbledore's absence: she protects the students from the sadistic Carrows, overthrows Snape, and leads the resistance against Voldemort when Harry returns.
The Room of Requirement was two rooms in this book, expanding as more students came in and then turning into the Room of Hidden Things.
Bittersweet Ending: Voldemort is gone once and for all, everyone who fought in the battle is hailed as a hero. Percy, Dudley, Kreacher, and (perhaps) even Malfoy finally make peace with Harry, and for once, a competent Minister of Magic is instated. The bad news? Lots of people are dead. Lots. And, annoyingly, a few people who probably deserve death or imprisonment seem to evade it in the end (or, at least, don't have their fates mentioned in the book). It's not a perfect world.
The Epilogue however, turns this into more of a Happy Ending. The Wizarding World has been rebuilt for the better, Dementors have been removed from Azkaban, and our heroes managed to get married and have children. Ginny and Harry married and had 3 kids, while Ron and Hermione married and had 2 kids, making the main trio in-laws. The ending shows the next generation of wizards heading to Hogwarts in a peaceful era, where the terror of Voldemort is nothing more then a painful memory. And Harry's scar hasn't hurt since Voldemort's defeat, signifying nothing but peaceful days to come.
Blatant Lies: After the ministry is taken over by Voldemort, they quickly adopt a strictly anti-Muggle policy, even setting up Inquisition-style hearings for Muggle-borns. And during one such trial, Dolores Umbridge flat out states that a Muggle-born she is interrogating is not a witch. Harry can't take any more after this. Fortunately, Word Of God states that Umbridge ended up in Azkaban for the rest of her life.
Bond Villain Stupidity: While Voldemort has insisted that he has to be the one to kill Harry, evidently that does not extend to personally making sure his foe is absolutely dead. Tropes being tools, if Voldemort had personally checked he may have resorted to more crude, muggle ways of ensuring Harry was dead.
Book Ends: After Harry defeats Voldemort for the first time (when he is but a one-year-old baby) Hagrid brings him to Privet Drive using Sirius' flying motorcycle. Sixteen years later, when the Order gets Harry away from Privet Drive before the blood wards fall, Hagrid is the one that takes Harry away... on Sirius' flying motorcycle.
The first time Harry sees Ginny, she's a small red-headed girl whining to her parents that she wants to go to Hogwarts with her older brothers now, not next year. In Ginny's last appearance, her small red-headed daughter is raising the same complaint to her and Harry.
Bowdlerise: A very unfortunate one for the Spanish translation. The incredibly awesome as hell Molly Weasley's Precision F-Strike got treated this way, from "NOT MY DAUGHTER, YOU BITCH!" to "Not my daughter, you bad witch!". note Rises from the use of "witch" as an insult, which makes no sense in a world where every female magic-user is called a witch. Fortunately, the film upgrades it to "harpy".
Broken Pedestal: Played with with Dumbledore, when Harry realizes that not only did he make a huge number of mistakes in his past and that he was not the perfect wizard he idolized, but that he was sacrificing Harry to kill Voldemort without even discussing it with him. And inverted with Snape, who he originally thought of as this horrible person he hated, but after realising the lengths he went to in order to protect him — to the point of infiltrating Voldemort's inner circle and dying for him — thinks radically differently.
Doubles as Book Ends. In Philosopher's Stone, Hagrid takes Harry to #4 Privet Drive for the first time... in Sirius Black's flying motorbike. Guess how Harry leaves forever at the beginning of this book.
There are many references throughout Deathly Hallows calling back scenes from many of the other books. Some examples are Harry reminiscing with Hagrid about how Hagrid told him he was a wizard way back in Philosopher's Stone. Another is Ron and Hermione actually re-entering the Chamber of Secrets in search of Basilisk fangs to destroy the Hufflepuff cup horcrux.
When Moody was explaining the escape plan from #4 Privet Drive, he refers to Fred, who proclaims to be George like he did way back in the first book to his mother. Unlike Molly, Moody has no love for it.
"I’m George," said the twin at whom Moody was pointing. "Can’t you tell even tell us apart when we’re Harry?" “Sorry, George—” “I’m only yanking your wand, I’m Fred really—” “Enough messing around!” snarled Moody.
James' first words to Snape ("Who wants to be in Slytherin? I think I'd leave, wouldn't you?") are almost identical to a line from Malfoy's first conversation with Harry ("Imagine being in Hufflepuff, I think I'd leave, wouldn't you?").
In the epilogue, James has come back, telling how he saw Teddy and Victoire kissing and asking them what they are doing. Ginny chides him for interrupting them, then commenting "you are so like Ron." That comment was in reference to the birthday kiss Ginny gace Harry early in the book where Ron intruded into the room interrupting them.
When captured by the Snatchers, Harry tells them he was from Slytherin House. They call Harry out on this, noting that many school-aged kids they capture say this, but Harry describes where the entrance is and how it looks. This was only possible because he and Ron had been there in the second book disguised as Crabbe and Goyle.
The Cavalry: Brought by Slughorn, of all people. And another with Kreacher.
Changed My Mind, Kid: Ron walks out on Harry and Hermione. He immediately regrets it, but due to circumstance he is unable to get back to them. His return, just in time to save Harry, is a Moment Of Awesome.
Children Forced To Kill: Averted. From the start of this series to the end of this book no Hogwarts student from Harry's generation has killed any other person, even in self-defense (not counting Crabbe's stupidity). This is despite these children being trained in powerful, often dangerous magic and being "of age" in this book - and involved in a battle where their own lives were on the line. This is probably to keep the kids from crossing the Moral Event Horizon. It's probably why it is Molly who kills Bellatrix, and not Neville - for Neville to do so may not have sat well with some parents and young readers.
Connected All Along: It's revealed that Lily and Snape were friends as Hogwarts students, and Snape was in love with Lily.
Conveniently Interrupted Document: Near the beginning, Harry finds a letter from one of his parents which mentions Dumbledore, and hints at a surprising revelation about his past. However, the second page of the letter is missing. He finds out much later that the revelation would have been of some use to him at the time, and that it was removed for reasons completely unrelated to any desire to keep it from him.
Cool Old Guy: With Dumbledore gone, we get his brother, Aberforth, who is almost as cool.
Neville's grandmother. Also overlaps with Never Mess with Granny, as when Death Eaters came to her house to try and capture her, she not only fought them off, putting one of them in the hospital, but went on the run as well. Now we know where Neville gets his guts from.
Professor McGonagall also counts, especially considering the final battle.
Corporal Punishment: We can only imagine what the hell is going on at Hogwarts while the heroes are running around the countryside. Neville certainly looks like he had a pretty rough time of it when he shows up after a year's worth of it. Apparently things would have been even worse if the Carrows had had the complete run of things. Even happens in lessons: "They had us practicing the Cruciatus Curse on first years.... That's where I got this [scar]. I refused to do it."
Cosmic Deadline: After many pages detailing a camping trip and other hairsbreadth escapes, suddenly the trio arrives at Hogwarts and truckloads of important, nay, essential information is revealed, and the plot relevant (or irrelevant) deaths start cropping up all over the place.
The cover to the American edition made it seem like Harry and Voldemort were in an outdoor coliseum during their final confrontation when it turns out to be the Great Hall at Hogwarts.
The Danish cover is much worse. At what point does this image◊ happen in the book? Granted, it's possible that that is a representation of the centaurs and/or Hogwarts statues joining for the battle, but the actual "order allies to battle" by Harry never occurs.
Crippling Overspecialisation: Voldemort, though the revelation builds on hints from previous books. Essentially all he ever cared about was the Killing Curse (or, more generally, the Unforgivable Curses) and using Horcruxes to live forever, and from his narrow knowledge wasn't even aware that he had possessed the Resurrection Stone (he was never interested in the Hallows, however). To the point that he still uses Avada Kedavra on Harry at the end despite it having backfired (in different ways) three times before. However, this is only with Harry, with everyone else, he brings out his most powerful curses, and even when Harry's sacrifice protects everyone, Voldemort still blasts Kingsley, McGonagall, and Slughorn out of the way when duelling all three at the same time. With the final Avada Kedavra that essentially kills Voldemort, he was kind of left with no other choice. He could not curse any of the defenders because they were protected by Harry's love, and even if he killed Harry, he would be attacked by everyone else. He really didn't have a choice.
Darker and Edgier: Given how each book in the Harry Potter franchise has invariably been darker than the last, it would make sense that Deathly Hallows is the darkest of them all.
The Dark Side Will Make You Forget: Severus Snape. When he started out he was a troubled neglected boy who just wanted Lily to like him. Then he got into Slytherin and things slowly turned rather dark at the influence of his friends. Then he got into the Death Eaters and completely forgot that blood-lines didn't used to matter to him, and things got worse to the point where he was trying to bargain with Voldemort to exchange Lily's own son's and husband's lives in order to save hers. Then he came back under Dumbledore's influence and ended up putting his life on the line to save other people, including Harry. So he wavered across the "Evil" line for a fair while there, obviously.
Day of the Jackboot: Voldemort and the Death Eaters complete their Nazi-style takeover of the Ministry of Magic.
Deconstruction: To some extent, the Deathly Hallows Fetch Quest introduced in the middle of the book is a kind of parody of the series Quest plot. Harry thinks the journey of the quest is significant, that it could give him the power he wants and that bringing the Hallows together means he has something over Voldemort's Horcruxes. The Hallows in the end, do nothing of the sort, indeed it is a Fetch Quest deliberately placed by Dumbledore all to prepare Harry to eventually sacrifice his life.
Despite The Plan: Twice. The trio spends almost a month planning the break-in of the Ministry, and another month planning the break-in of Gringotts. Both times, the plan goes wrong almost as soon as they get in, and they end up having to improvise. It's even lampshaded in the film version.
Harry: Hermione, when have any of our plans actually worked? We plan, we get there, all Hell breaks loose!
The Determinator: Hagrid will get Harry to safety, even if it means leaving his friends to deal with the Death Eaters. Even Harry wanted him to turn back to help.
Determined Defeatist: Aberforth Dumbledore is convinced that Voldemort is going to win and advises the heroes to give up and flee the country. Naturally, he still shows up to fight when push comes to shove.
Did You Just Scam Cthulhu?: Narcissa Malfoy is apparently a Occlumens to match the world's greatest Legilimens-perhaps even learning to do this on the fly.It is possible that Narcissa blocked Voldemort out with her love for Draco, akin to what Harry did in the fifth book.
Disney Death: Harry Potter himself, although the reader knows he isn't really dead. However, those who believed J.K. Rowling's hints that he'd die at the end of the seventh book would certainly be surprised.
The youngest Peverell brother, having lived to age after a full life, meets up with death like an old friend. The movie actually shows the two embracing. It's surprisingly heartwarming in the context.
Dumbledore gives a similar message to Harry at King's Cross.
Ultimately what it truly means to be the "Master of Death." He does not escape death, rather he accepts that death is inevitable, and that there are far worse fates than dying.
Doorstopper: While this book does count, an in-universe example is Rita Skeeter's "The Life and Lies of Albus Dumbledore" which goes on for about 900 pages—and written in about four weeks!
Dragon Hoard: When breaking into the LeStrange vault to steal the golden Cup of Helga Hufflepuff, Harry, Ron and Hermione have to pass one of Gringotts' trained guard dragons. The dragon itself is non-sapient and presumably doesn't care about gold itself.
Earn Your Happy Ending: Many people do die, but in the end the Big Bad Voldemort is defeated once and for all, and the world is finally a better place.
Easily Forgiven: Percy Weasley after having been estranged from his family since the hiatus between Books 4 and 5. Most surprisingly, the first person to welcome him back is Fred, who was among his most vocal detractors following Percy's defection. It helps, though, that Percy doesn't need prompting to admit—publicly and loudly—that his behavior in the previous books was foolish and wrong, and that he fully agrees with Fred's highly insulting assessment of said behavior.
The Malfoy family, who managed to escape punishment for their crimes due to their last minute Heel-Face Turn.
Ron, when he returns after leaving Harry and Hermione. As Harry points out, Ron not only saved his life on returning, but was Brainwashed and Crazy when he left in the first place. Toyed with on Hermione's part, as she obviously forgives him instantly, but tortures him (metaphorically speaking) on a regular basis until she feels enough time has passed to show it.
Enemies with Death: In The Tales of Beedle the Bard. Subverted, in the end, by the third and final brother. With several philosophical ties to the over-arching themes of the story.
Entertainingly Wrong: In Half-Blood Prince, Harry and Dumbledore theorized that Voldemort used his attempt to get a job at Hogwarts as a means to try and get hold of the Sword of Gryffindor to use as a Horcrux. Harry realizes they had it backwards, and Voldemort used the job interview to hide a Horcrux, with possibly gaining access to the sword a potential bonus.
Eureka Moment: Harry figuring out where the last Horcrux is hidden.
Even Evil Has Standards: We never find out for sure how Regulus felt about being a death eater (in short exactly how evil he was)- we only hear stories second hand from people who weren't involved in his death. However it seems to be that when he learned that Voldemort had made a Horcrux and used Kreacher as a disposable tool this was over the line in his opinion.
Grindelwald, who lied to Voldemort about the Elder Wand, and laughed in his face (though annoyingly this is completely reversed in the film).
The Third Brother from the Tale of the Three Brothers has this in spades, welcoming death as an “old friend”.
Harry, when he faces Voldemort in the Forbidden Forest.
Fake-Out Opening: The first line of the second chapter of the book - and the first appearance of Harry in the book starts out "Harry was bleeding.", catching the reader off guard and making them wonder what terrible thing has befallen Harry before the book even began. It turns out he merely cut his finger while cleaning out his school trunk.
Fighter, Mage, Thief: The Elder Wand (Fighter), the Resurrection Stone (Mage), and the Invisibility Cloak (Thief).
Fighting Fingerprint: When Harry uses the disarming spell against Stan Shunspike, the Death-Eaters, who've come to see it as his signature move since he used it Voldemort in Goblet of Fire, recognise it and change course to attack him.
Figure It Out Yourself: While the Power Trio is on the road trying to figure out what they have to do, Hermione suggested this trope as a rationale for why they had to do something while Lampshade Hanging how little sense it makes. Later on, when Harry turned the same rationale on her for a different goal, she admitted that she didn't really believe it and was just trying to get her way in the first place. Of course, Harry turns out right anyway.
Four Is Death: Leading up the final battle, Voldemort has used the Killing Curse on Harry 3 times: First in Godric's Hollow as a baby, later in the cemetary after being resurrected, and again in the Forbidden Forest. He tries it one last time, and pays the ultimate price for it.
Freudian Slip: Snape calling Lily a "Mudblood" turned out to be this. He claimed that he never meant to say it, but she doesn't believe him and ends her friendship with him, realizing what kind of person he had become.
Full Name Ultimatum: "You-complete-arse-Ronald-Weasley!" and "Don't you tell me what to do, Harry Potter!"
Generation Xerox: In the epilogue, Ginny's daughter Lily cries at the train station the same way she did at that age. Harry's oldest son James is a bit mischievous like his namesake. Harry's second son Albus is said to be the spitting image of him, including the eyes, and has similar fears of being placed in Slytherin. Meanwhile, Draco's son Scorpius is his own image.
Ginny's "farewell present" to Harry, cut short by Ron's interruption.
Harry's daydreams/memories when the Weasleys' Auntie Muriel remarks that Ginny's dress is "far too low-cut". Ginny follows this with a wink at Harry and Harry's thoughts drift "far away, back to stolen hours spent in secluded spaces of the Hogwarts grounds..."
Another moment came when Ron was being told to pick up his room for his brother's wedding, and he irritably responds "Are they getting married in my room? No! So why in the name of Merlin's saggy left—", before he gets cut off by his father.
And the subtext in this dialogue, it goes past very quickly so it's easily missed over all the action. Harry asks Ginny where Hermione and Ron are just before the battle. Ginny replies that they left mentioning something about finding a bathroom, prompting a Flat "What." and "You're sure?" from Harry. They were going to the Chamber of Secrets, but at this point no-one knows what they have in mind, do they?
Go Look at the Distraction: After Harry defeats Voldemort, he wants time to talk to Ron and Hermione in private, and Luna points out one of her made-up creatures, making people look away from Harry so he can escape.
Good Is Not Nice: Harry had used the occasional Unforgivable Curse in moments of extreme stress in previous books, but it really gets turned Up to Eleven in this one. Many fans complained about this and about Dumbledore's interest in the dark arts; J.K. Rowling stated that she never depicted Harry or Dumbledore as white knights.
Gotta Catch Them All: The entire plot rests on this. Harry, Ron, and Hermione have to search for all of Voldy's horcruxes; but after learning about the Deathly Hallows themselves, Harry debates for a while and then decides not to race Voldemort to the last one. Perhaps a double subversion, since Harry does get it in the end?
Growing Up Sucks: Invoked in this novel as the previous installments have had Harry, Ron and Hermione at Hogwarts where despite the horrible things that happen to them they still had a large circle of friends, three large meals a day, adults watching over them, and schoolwork to keep them distracted. In this book they lose all of that, and have to deal with it - symbolizing a cold shove into Adulthood.
The Guards Must Be Crazy: The snatchers fail to confiscate Ron's Deluminator, Harry's piece of mirror, and Hermione's handbag, despite the fact that one is a magical device, one a potential weapon, and one a Bag of Holding. Perhaps justified in that the wizarding world tends to focus on spells and wands, rather than the vast number of different weapons that Muggles use. Still, doesn't explain why they allow Harry to keep his mokeskin pouch (where the shard is hidden, as well as Harry's broken wand) and Hermione to keep her handbag (the book states that they somehow missed it as she'd stuffed it up her sock, but still)....
The Hecate Sisters: When Harry enters the Room of Requirement while the Battle of Hogwarts is going on he finds the room empty except for three women who had not yet joined the fight. The first to exit is Mrs. Longbottom who goes to assist her grandson. The second is Tonks who left her baby with family out of concern for her husband. The third is Ginny who eagerly joins the fight being responsible for no one but herself.
Snape, back when he first joined the Death Eaters and found out about Trelawney's prophecy concerning Harry.
Hellfire: Fiendfyre. Of course, isn't explicitly demonic, "just" powerfully magical, near-sentient and capable of burning through a cathedral-sized storehouse in minutes. Oh, and it's a lot harder to stop than start.
By Harry at the end when he has to face Voldemort so he could kill him.
Snape gave his entire life to Dumbledore in return for helping to keep Lily safe, and then later to protect Harry, even infiltrating Voldemort's inner circle to do so, which eventually resulted in his death.
Many of the students at the Battle of Hogwarts were fighting and dying to allow Harry the time to find and destroy the diadem Horcrux.
Voldemort is killed by his own reflected killing curse. Again.
Remember how Voldemort got so evil that he created an accidental Horcrux in Harry's scar? Hell, remember the Schrodinger's Prophecy he could've chosen to ignore, but didn't, and in doing so, created his own worst enemy? You-Know-Who is practically the king of this trope.
Imperial Stormtrooper Marksmanship Academy: Applied to the Seven Potters chase. There were fourteen good guys against an unknown number of bad guys with the bad guys having a numerical advantage. While it was justified for poor aim as they were all flying on brooms and constantly moving, the good guys had three casualties one death by Voldy, one errant spell aimed at someone else, and one self-inflicted near suicide action, not counting Harry's injuries caused by his crash, the good guys had a lot more hits and probable kills.
The Sword of Gryffindor, appropriately enough. Shame no-one uses it for legitimate sword fights to demonstrate its true potential.
Ironic Echo: In Book One, Ron yells "Are you mad? Are you a witch or not?" to Hermione. In this one, she yells at him, "Are you mad? Are you a wizard or what?"
It Is Not Your Time: Harry's Near Death Experience at the end of the book. He meets Dumbledore and during this time they discuss his going back to the living. It turns out Harry has a choice - he can move on or return to life.
Jack Bauer Interrogation Technique: Harry, Hermione, Ron, and Kreacher, after capturing Mundungus, pretty much use this trope to force him to reveal who he sold Slytherin's Locket to, and then (although by accident rather than deliberately, due to the shock of the revelation of who he sold it to) scald him.
Voldemort. Try to act surprised. The movie one-upped it though, where he was not only killed by the Avada Kedavra backfiring on him from the Elder Wand, but he also ended up disintegrated as well, not even leaving his body behind.
Knight Templar: The young Dumbledore at the time when he was tempted to join Grindelwald's quest to take over the world - he wanted to liberate wizards from having to live in hiding (especially poor Ariana). He stressed to Grindelwald that they should use the minimum amount of force required and that with their power Comes Great Responsibility. Subverted with Grindelwald, who may have come across as one (even using the slogan "for the greater good") but was probably only in search of power.
Leaning on the Fourth Wall: Rowling has stated that the phrase on the Snitch ("I open at the close") is one in regards to the books themselves. Specifically, Deathly Hallows takes place in the 1997-1998 academic year. In Britain, 1997 was the year that Harry Potter and the Philosopher's Stone was published. In America, Harry Potter and the Sorcerer's Stone wasn't released until 1998. The book series opens in the real world during the years that the book series closes in the Wizarding World.
Love Redeems / Love Hurts: Snape gets hit with both with regards to Lily. He not only fails to save her, but then spends the remainder of his life trying to protect the son she had with the man he hated, despite the fact that he tried to keep him in detention for most of his school life. It probably didn't make things any easier that Harry looked exactly like James but with Lily's eyes. Ouch.
Okay, so everything is basically magic, but the true story of the Deathly Hallows is never fully explained. Are they powerful magical items made by skilled wizards, or did they really meet death and he gave them the items? There are elements of them which can't be explained within the continuity of the story, unless you accept the story about Death.
Also, everything that happens in "King's Cross". As Harry says, "Is this all in my head or is it real?" and gets a Mathematician's Answer in response. Since Harry doesn't learn anything he couldn't have worked out on his own, there's really no way to be sure.
Moment Killer: Twice: once by Ron and the other time by Harry. Harry did have a good reason for it, though.
"OI! There's a war going on here!"
Happened during the epilogue and acted as a Call Back when James Sirius interrupted Teddy and Victoire snogging at Platform 9 3/4.
Monster Fun Facts: Many books have a passage like this when Harry is learning about monsters in school; in this one Harry doesn't go to school but runs down a list of things at Voldemort's command to the Dursleys (who don't know much about magical stuff), including:
"...and Inferi — that is, dead bodies animated by a dark wizard..."
Monument Of Humiliation And Defeat: After Voldemort takes over the Ministry of Magic through his puppet leader, he destroys the old fountain in the atrium (which depicted a witch, a wizard, a centaur, an elf and a gnome as a symbol of magical cooperation) and replaces it with a wizard and a witch sitting on a (black in the books, white in the movies) throne being carried by hundreds of suffering Muggles. The words "MAGIC IS MIGHT" are inscribed on it to make its claim clear that wizards are superior to non-magical creatures.
Morality Pet: Lily for Severus. The fact that she was dead for seventeen years didn't seem to change this fact.
Mortality Ensues: The Horcrux-destruction plot is all about causing this for Voldemort.
MST3K Mantra: In-universe, when reading the Tale of the Three Brothers, Harry questions the sudden appearance of Death. Hermione reminds him that it is a fairy tale.
M-Word Privileges: Hermione refers to herself as a Mudblood and when Ron objects, she explains that she's proud that she can refer to herself that way instead of the Death Eaters doing it.
My New Gift Is Lame: Pointed out by Ron when Hermione gets a book of fairy tales, Ron gets an item which can manipulate light, and Harry gets... an old snitch. Harry, however, knows that with it coming from Dumbledore there must be a secret involved, though — and there is. Also the Snitch was the very one that Harry caught in his first ever Quidditch match, which if anything gave it some sentimental value, which in fact was useful to conceal even more of its true purpose from the Ministry.
Naked People Are Funny: Mad-Eye's plan to sneak Harry out of his house involves everyone transforming to look like him and flying off in all directions. When they change clothes, Harry is annoyed that no-one is particularly bashful about getting naked while disguised as him.
Negate Your Own Sacrifice: Harry has to die, since he's a Soul Jar for Voldemort. Fortunately Voldemort's new body was made with Harry's blood, which anchors him to the living world. Harry didn't actually know this would happen and fully expected it to be a Heroic Sacrifice. Though the blood wasn't enough in itself; according to Dumbledore, Harry's decision to let Voldemort kill him rather than keep fighting was what "made all the difference".
Never Mess with Granny: Aurors in their prime try to take down Augusta Longbottom. One of them is still in the hospital at the time of the final battle.
Also, for some reason, Voldemort can fly. There was some Foreshadowing though: his name means "Flight of Death" in French.
Nice Job Breaking It, Hero: The Trio's Gringotts heist. Yes, they manage to snag Horcrux #4, but they lose the Sword of Gryffindor (their only tool for destroying Horcruxes) in the process. Worse, it also finally tips off Voldemort that they've gone Horcrux hunting — a development they were understandably hoping to avoid as long as possible.
Speaking of Voldemort, his reaction to learning that Harry and company have nicked the Horcrux he hid in Gringotts. In his fury and fear, he unknowingly drops his Occlumency shields and Harry again gets unauthorized access to his thoughts. This glimpse confirms Harry's suspicions that Horcrux #6 has been at Hogwarts all along — thus setting the stage for the final battle of the Second Wizarding War.
And he also sends someone to lay in wait for Harry in the Ravenclaw dorm, confirming Harry's suspicion about what the Horcrux was.
And, to top it off, the entire situation at Hogwarts was due to the actions of his own people in torturing the students. If the situation hadn't deteriorated into open rebellion, the Trio wouldn't have even been able to get in, at least not before Voldemort got there.
And then there's Bellatrix when the Trio are brought to Malfoy Manor. When she realizes they have the Sword of Gryffindor, she goes beserk. Bellatrix starts torturing Hermione to determine if they've been in her Gringotts Vault (where the Sword was moved to after Luna, Neville, and Ginny tried to nick it back at Hogwarts). Bellatrix's terror, combined with his understanding of Voldemort's psychology, tips Harry off that one of the Horcruxes may be in the Vault.
Going for the hat trick with Voldemort, there's his tactical blunder in declaring a cease-fire in the middle of the Battle of Hogwarts. He does this to issue an ultimatum to Harry to surrender within one hour and to allow his forces to regroup in the Forbidden Forest. However, the total time lost due to the cease-fire, Voldemort and Harry both being knocked into unconsciousness via the Killing Curse, and the march back to the school grounds ends up backfiring. It gives Horace Slughorn and Charlie Weasley enough time to gather overwhelming reinforcements from Hogsmeade and throughout Wizarding Britain including Hagrid shaming the Centaurs into ending their neutrality.
No Man Should Have This Power: Harry regards the Hallows as this. At least the Wand and Stone (from dialogue in the book, one can assume he kept the Cloak). He lost the stone in the forest, and deliberately refuses to look for it again. Also, in regards to the wand, in the book, he put it back in Dumbledore's grave with the hope that he, Harry, would die naturally so the cycle of violence over the wand would end. In the movie, he is much more pragmatic and simply snaps the wand in two.
Ron and Hermione recovering the basilisk fangs from the Chamber of Secrets. This could have been used to show another spiritual illusion to try and stop them, like with the locket, but it was left out due to the book's Cosmic Deadline (see above). Happily, it's included in the movie.
In the book, before the Dursleys leave Privet Drive, Dudley shows concern about Harry’s safety, tells Harry that he doesn’t consider him to be "a waste of space," is thankful to him for saving his life, and even shakes his hand. For Dudley, this is positive Character Development and a Moment Of Awesome rolled into one, because it presents Dudley as finally accepting and appreciating Harry. Disappointingly, this is left out in the film, though it's included in the Blu-ray deleted scenes.
Also in the book, Dean Thomas is seen in the final battle casting spells with a new wand, having obtained it during the battle, as we see him enter the final battle without one. It's true he's a minor character, but this is an unarmed teenager who took ownership of a wand by forcefully taking it from a trained killer in the middle of a kill or be killed melee between good and evil.note A more Tear Jerking alternative is that he acquired said wand from the body of a dead ally, but his actions during the battle are still awesome nonetheless
Poor Communication Kills: Played with. Throughout the series Dumbledore knew everything that was going on but did not tell Harry, for reasons which many speculate - and Dumbledore admitted - may have been unnecessary. In this book, Harry, Ron and Hermione are the only ones who know what is really going on but don't tell anyone else, either.
After six books where Harry is always telling his friends to stay safe and that he will do things on his own, this book shows how he finally accepts his friends' help.
What pushes Ron to come back to his friends right after leaving them. He is helped by the Deluminator in this task. Harry even says it.
"[Dumbledore]—well, ” Ron’s ears turned bright red and he became engrossed in a tuft of grass at his feet, which he prodded with his toe, “he must’ve known I’d run out on you. ” “No, ” Harry corrected him. “He must’ve known you’d always want to come back. ”
Prodigal Hero: Harry had to flee and hide all over England to stay a step ahead of Voldemort, but when the last Horcrux was hidden in Hogwarts and he found that out, he rushed to Hogwarts to find it, which sparked the Final Battle.
Protagonist-Centered Morality: Subverted. Harry uses the Cruciatus curse, but this was so that the audience would recognize his flaws, not change their mind about the appropriateness of Dark Magic. Also uses the Imperius Curse on both a goblin and a nosy Death-Eater during their raid on Gringotts in search of a horcrux.
The Ministry of Magic under Voldemort. The Death Eaters' skull is even similar to the totenkopf of the SS.
Nurmengard, Grindelwald's prison for his enemies, is a thinly-veiled Auschwitz, right down to the slogan written over the gates. Considering Grindelwald himself was later imprisoned there, it might double as a reference to Nuremberg.
Retired Badass: Averted with Harry and Ron when they grow up, but played straight with almost every other major character. Particularly Neville, who settled into a nice, quiet teaching position at Hogwarts. Word Of God says Ron helps run Weasley Wizards Wheezes with George and also after the battle of Hogwarts that he does become an Auror with Harry and Neville. Whether he's still an Auror or working with George at the time of the epilogue is unknown.
Revealing Skill: While being ambushed en route to The Burrow in the beginning, Harry unwittingly reveals himself when he uses the Disarming Charm — his signature move — against Stan Shunpike (who Harry believes is being forced to participate in the ambush against Harry via the Imperius Curse.)
Right for the Wrong Reasons: Hermione does this when she uses the information that basilisk venom destroys horcruxes to reason that the sword of Gryffindor will do the same. It does, but it still seems to be a complete fluke: she believes that the sword blade is impregnated with venom because the sword killed the basilisk, and "the sword only absorbs things that make it stronger".Apparently, snakes have their venom in their blood.
Justified actually; Harry stabbed the snake through the roof of its mouth, presumably straight through a venom pouch.
Room Full of Crazy: One might count Luna's bedroom. Granted, the girl hasn't a malicious bone in her body and none of it is sinister, but, well... portraits of people you like all linked by gold chains made of the word "friends" does go a little beyond Cloudcuckoolander. Opinions differ on whether this is heartwarming or stalkerish. All of the Lovegoods' house counts, really.
Sadist Teacher: The Carrows, a pair of ruthless Death Eater siblings, take over disciplinary matters and Defense Against the Dark Arts at Hogwarts this year. You know they're bad when Neville says they make even Umbridge look good by comparison.
Sealed Evil in a Can: It's implied that Voldemort's final fate is to remain in a sort of limbo (specifically, the netherworld where Harry met Dumbledore after he died) forever, incapable of harming anyone ever again.
Secret Test of Character: The Sword of Gryffindor was placed under the frozen lake ostensibly to serve as some kind of test of bravery and determination. Harry realizes that immediately, but still points out that it seemed less of a test of character and more making things unpleasant for the hell of it.
Where "chivalry" entered into this, he thought ruefully, he was not entirely sure, unless it counted as chivalrous that he was not calling for Hermione to do it in his stead.
Self Healing Phlebotinum: According to the Lovegoods, Snorkack horns reform a few months after exploding, unlike Erumpent horns. Only the latter are known to exist, the former widely regarded as a myth.
Self-Induced Allergic Reaction: Hermione's quick thinking allows her to prevent Harry from being recognized by the Snatchers when they're surrounded in the woods. However, the disguise isn't foolproof, and the trio have to rely on Malfoy to look the other way and pretend he can't tell whether it's Harry or not.
Self-Made Orphan: It's revealed that Ariana Dumbledore accidentally killed her mother Kendra.
Spotting the Thread: Luna Lovegood sees through Harry's disguise at Bill and Fleur's wedding simply from the expression on Harry's face.
Start of Darkness: A variation. This time, instead of seeing Voldemort's transition from cute, troubled kid to full-on genocidal maniac, we get to see Snape's transition from cute, troubled kid to troubled heartbroken adult, and Dumbledore's transition from cute, troubled kid to wise manipulative Chessmaster — both of them dabbling considerably in the Dark Arts for a while. Apparently coming from a broken home is a pre-requisite for this kind of thing. Interestingly, all three of them were Insufferable Geniuses as teenagers.
As Dumbledore noted in the previous book, Harry is the greatest aversion, he had a background and upbringing similar to theirs but somehow became compassionate and mature, avoiding the Pride that led them to commit terrible mistakes.
Strictly Formula: The fact that these youth are used to the formula of three large meals a day and adults looking over them gets yanked out from under their feet.
Sue Donym: The Potterwatch radio crew refer to themselves by ridiculously transparent pseudonyms based on their actual names: Lee Jordan is River, Kingsley Shacklebolt is Royal, Fred Weasley (weasel) starts as Rodent (quickly changed to Rapier, presumably for "rapier wit"), and Remus Lupin exhausts the last untapped blatant reference in his name by going as Romulus. To their credit, Kingsley is the wizard James Earl Jones as far as vocal recognition goes and they would have been killed on sight anyhow for belonging to the Order of the Phoenix, so protecting their identities wasn’t worth much.
Professor McGonagall leads the defense in the Battle for Hogwarts to give the Power Trio the time to find the final Horcrux, even though she has to trust Harry by his word alone.
Also, former Butt Monkey Neville Longbottom lead the student resistance in Harry's absence.
Reading between the lines, Kingsley Shacklebolt becomes the Big Good after Dumbledore's and Moody's deaths and later becomes the first competent minister of magic in years. But from Harry's point of view he remains a peripheral character.
Sword of Plot Advancement: The Horcrux-destroying plot only takes off after Harry, Ron and Hermione find where Gryffindor's sword was hidden.
Take Off Your Clothes: Hermione makes Harry and Ron take off their wizards' robes so they can pass as Muggles.
That Liar Lies: Harry shouts "LIES!" to no-one in particular when first reading some of the media references to Dumbledore's Feet of Clay. The melodrama of this is lampshaded in that a Muggle neighbor is shown to overhear and glance around nervously.
Took a Level in Badass: Virtually everyone, but particular standouts include Mrs. Weasley, Prof. Slughorn, and above all Neville Longbottom, who in some ways really is the biggest hero in the story. Special notice for Sybill Trelawney, who took out several Death Eaters (including Fenrir Greyback) by using magic to throw crystal balls at them.
Too Dumb to Live: Sure, Voldermort. Continue to cast the Killing Curse on "The Boy Who Lived", even though it is clear that the spell backfired on you. Brilliant.
Tracking Device: A running quirk in the first book, revealed by Ron in the last: there's a reason why wizards won't dare speak Lord's Voldemort's name. The spell that made that possible wasn't in use until the last book. So it was safe to actually say Voldemort's name until that spell was cast.
Tragic Dropout: The Trio. It's not like any of them would have dropped out of Hogwarts if Voldemort hadn't truly taken over. Before the release of Deathly Hallows, fans debated endlessly if the trio had been serious about dropping out of Hogwarts or not - or if they would be forced to attend.
Word Of God says after the war Hermione went back and finished up her N.E.W.T. studies, while Harry and Ron did not.
The heroes had one in place as well. Dumbledore originally planned to depower the Elder Wand by having Snape kill him by consent. This was ruined when Draco Malfoy Disarmed him during their encounter, and Dumbledore never got a chance to reclaim it. Later, Harry Disarmed Draco of his usual hawthorn wand, taking it for his own—and by doing this, Harry (by pure luck) became the master of the Elder Wand, essentially preventing Voldemort from ever becoming its master. This is eventually what allows Harry to win against Voldemort.
Unishment: Punishment to Neville, Luna and Ginny for trying to steal Griffingdor's sword from Snape's office is... to go to Forbidden Forest and help Hagrid. See Corporal Punishment above for why that's not so bad.
Villainous BSOD: Averted. The master of a Horcrux can repair his soul by feeling regret — which, given what their creation entails, often means that they'll feel so much pain that they'll die — but Voldemort has to be killed the normal way. Having to do it the old-fashioned way is meant to illustrate that Voldy is irredeemable.
What Could Have Been: Working titles were Harry Potter and the Elder Wand and Harry Potter and the Peverell Quest. The latter was rejected for being way too cheesy, but the former would have made a lot more sense, especially since the other Hallows (the Resurrection Stone and the Invisibility Cloak) aren't really important to the story the way the Wand is. The Stone is only discovered towards the end and put to use exactly once, and while the Cloak sees a fair amount of use, it's nothing that Harry hasn't done before, and it isn't over-used.
Snape delivers one of these speeches to Dumbledore, after he reveals that Harry (whom Snape has been protecting) must die in order to defeat Voldemort. It's the one time that Snape gets properly angry at Dumbledore.
Harry delivers one to Lupin, when he offers to abandon his family to help the trio on their quest, largely out of self-loathing.
Voldemort delivers one to Harry, accusing him of using his friends and classmates as meatshields during the final battle.
Crabbe proves that he's not only willing to do this, but is also willing to set one on fire.
A non-lethal version involves Harry merely knocking Umbridge unconscious with a spell.
You Have Failed Me: Wormtail's silver hand was enchanted to kill him if he ever betrayed Voldemort. He does so accidentally.
Inverted when Voldemort kills Snape. Voldemort even acknowledges that he did nothing wrong, but has to die anyway.
You Have Outlived Your Usefulness: Snape is the presumed master of the Elder Wand. Voldemort wants the Elder Wand. To master the Elder Wand, you have to kill the current Master or overpower them in some other way. Guess where this is going.
Youngest Child Wins: The third Peverell brother is the only one who doesn't die as a consequence of his Hallow.
