Frank Bryce's death. The old groundskeeper was accused of murdering his snobby employers and thus has become a mistrustful outcast in Little Hangleton; ironically, he saw the real killer, a younger Voldemort. Despite that, he maintains the grounds of the Riddle Manor faithfully and shoos away teens. One nigh, two men break into the house, and Frank realizes that he needs to get help after overhearing they murdered a woman and plan to kidnap a boy named Harry Potter. Unfortunately, he gets caught, and he knows that he's a dead man. Frank goes out mouthing off to Lord Voldemort and bluffing him, only to scream when seeing the man's true form. Voldemort kills him and casually disposes of the body. Rest well, Frank. You deserved so much better.
Molly's Adult Fear when her family returns from the Quidditch World Cup. Rita Skeeter had exaggerated the riots in the paper, as usual. Molly pulls Fred and George into a hug because the last thing she said to them before they left was a lecture about how they wasted their time making toffees rather than studying for their OWLS. Fred and George are embarrassed, but their mother is apologetic and relieved they weren't hurt.
Harry mentions that it's Voldemort and the Death Eaters' fault for destroying families: Mentally shattering Neville's parents, implied to having hurt one of Hannah Abbott's parents, killing Moaning Myrtle, ruining the Crouch family, killing most of the Tonks family, forcing the Malfoy family to be separated, and killing Harry's parents, godparent, and James's friends.
Harry thinking about his relatives never hugging him, like a mother would, when Molly hugs him. Not to mention that, all the while, he was fighting back tears over Cedric's death.
Harry: I told him to take the cup with me.
This is awful on so many levels, because while Harry doesn't constantly angst over not having parents, the degree to which that void is felt in his life really comes through in times of crisis. In fact, he's grown so used to not having adults in his life that being genuinely cared about feels sort of foreign to him.
And it gets worse; surely his mother held him like that when he was a small baby. He would understandably not remember.
In a good way, Molly giving Harry an epic hug to try and help him through. It's a short moment, but it perfectly encapsulates Harry's relationship with the Weasleys: They are his real family. When Molly states in the next book that Harry is "as good as" her own son, thanks to this moment, you know it's the absolute and unvarnished truth.
Cedric's father, who acted like a pompous Jerkass towards Harry in the book, didn't take the Triwizard winnings and also let Harry know that he doesn't blame him for his son's death.
Dumbledore's speech at the end eulogizing Cedric. Cho cries silently.
Dumbledore: If the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort.
Making it even more tragic is that when Crouch Sr. appears in his insane state and thinks he's talking with co-workers. He brags about Barty obtaining twelve O.W.L.S., demonstrating that he was still proud of his adolescent son's accomplishments even if he didn't spend so much time with him. One wonders how Barty might've turned out had he had heard his words when he was younger or knew about how often his father discussed him at the office.
When Cedric's echo asks Harry to take his body back to his parents.
This piece is sad:
And now another head was emerging from the tip of Voldemort's wand... and Harry knew when he saw it who it would be... knew, because the woman was the one he'd thought of more than any other tonight...
Depending on what version you've read, it's actually James coming out of the wand. The version with Lily is arguably more sad however.note The original version of the text was James first, then Lily; however, it was pointed out that as the victims are appearing in reverse order, it should be vice-versa, and later printings were changed to fix this.
Cedric's death is tragic, not just because he's been a Nice Guy and Worthy Opponent, but because it's senseless. Voldemort isn't even having Wormtail kill him out of malice; just convenience.
Harry having to tell Cedric's parents how their son died. After the interview, Mrs. Diggory, likely trying to think of anything to give some comfort to her and her husband, points out "He suffered very little then, and after all, Amos, he just won the tournament. He must have been happy." Then Harry tries to give them the prize money, but she refuses it.
More of Fridge Sadness here, but Viktor's "person he'll miss the most" is Hermione, a girl he's known for only a few months. It's also implied that, though he really likes her, she doesn't spend a ton of time with him out of loyalty to Harry. No best friends at school, no family members brought in; how lonely must this guy be?
Very, most likely. He's most likely the target of a lot of people either being jealous of his talent and achievements, or so star-struck by his fame that they fail to see him as a real person. Not So Different from Harry's own social situation coming to Hogwarts for the first time, actually...
Another Fridge Sadness. Viktor confronts Harry about the Skeeter rumors. Harry quickly assures him they are garbage and that he and Hermione are Just Friends. Then he and Viktor start to compliment each other's flying before Crouch. Sr. interrupts them. It's sad to think that this is the closest to friendship Viktor and Harry get, due to them spending the rest of their time training for the Third Task and then the year ends all too soon.
Sirius having to leave Harry again in the aptly-titled chapter "The Parting of The Ways."
McGonagall's response after she, Snape, and Dumbledore rescue Harry from Crouch Jr., doubling as a Heartwarming Moment. At first, she's close to tears once Harry's out of danger, though she puts up a brave front in Mama Bear mode. She notices how shaken Harry is, that he's got an injured leg that hasn't been treated, and whispers to him to come to the hospital wing. When Dumbledore overrides her, she protests "Dumbledore, he ought to— look at him— he's been through enough tonight."
Ron and Harry fighting. We're used to seeing Ron and Hermione fighting, but we never really seen him fight with Harry. In a minor way, it's sad to see. It's especially sad because, as the Fridge page points out, Ron actually tried at least a couple of times to mend bridges, but it's not very obvious because the books are from Harry's POV.
Winky's ordeal is heartbreaking. She was the Crouch family's loyal house-elf who not only served them faithfully, but sincerely loved her masters. She did everything for them. She took care of Barty Jr. after he was smuggled out of Azkaban, even persuading his father to give him small rewards for good behavior and allowing him to watch the Quidditch World Cup. How is she repaid for her love and loyalty? Barty Crouch Sr. coldly fires her the moment that his son escapes, dismissing her the second he decides that she's no longer useful to him. Barty Jr. took advantage of her maternal love for him so he could escape his father's hold and run back to his master, Lord Voldemort. He didn't believe that she (or anyone else) truly loved him, and believed she was only doing what she was bound to do as the family house-elf. Even after being banished from the Crouch household, Winky blames herself for her failing and continues to pine for her master, who doesn't love her, never did, and never appreciated everything she did for him. Her devotion was repaid with nothing but cruelty and rejection.
From the Film:
That's My Son!
Harry's parents telling him to let go. Even though it means he might not see them again for a long time.
Lily Potter: Sweetheart, you are ready. Let go! Let go! Let go...
The moment when Harry returns from Voldemort's revival party with Cedric's body.
The part where Harry is crying over Cedric's body and hugging it. And when Dumbledore tries to get a better look and gently move Harry out of the way, Harry responds by sobbing "No!" repeatedly and shoving the headmaster away, still clinging to the body. It's particularly jarring as Harry is unable to cry in the book.
As in the book, Dumbledore's eulogy for Cedric, even though it's mostly a watered-down version of the canonical speech.
Although they don't get much focus during the scene, Fleur's scream of pure terror and Cho crying as they see Cedric's body. It shows their actresses can really act.
Really, just pretty much everyone's reactions in that scene (particularly Dumbledore and Hagrid as they gradually realize what's happened after Fleur's scream) illustrate perfectly why it's one of the most heart-wrenching scenes in the whole film series.
The Mood Whiplash makes it all the keener. We, the audience, have just come from a tense, scary, and incredibly sad scene with Cedric's death, Voldemort's rebirth, Harry almost dying at Voldemort's hands, and finally the ghosts of Harry's parents buying him precious seconds to escape. Harry and Cedric's body travel via Portkey back to the start of the Third Task, and everyone starts cheering and celebrating, jaunty music begins to play, which feels horribly wrong because of what we, the audience, know. You may have even forgotten that all of Hogwarts was waiting patiently for a victor to emerge in this oh-so-important tournament. THEN the other characters begin to catch up to where we are, the music petering out as the sadness and horror slowly dawns...
Unsurprisingly, Word of God confirms that the Triwizard Tournament was never held again after Cedric's death, his tragedy casting a permanent shadow over the entire event which was already infamous for the many lives it had claimed.
At the farewell feast, the Great Hall's ceiling is not enchanted to show the sky. This isn't unexpected, as Hermione explained in the first movie that it's not real.
Minor compared to other examples here, but the end of the argument between Hermione and Ron after the Yule Ball about her going with Viktor Krum. In the book, they were both just furious and shouting at each other, but in the movie, Hermione is clearly fighting back tears because Ron has actually really hurt her feelings. She's choking up and on the verge of completely breaking down by the time she's finished.
Hermione: Next time there's a ball, pluck up the courage and ask me before somebody else does! And not as a last resort!
The torture and ultimate death of the whip spider on which Crouch!Moody demonstrates the Unforgivable Curses in his Defense Against the Dark Arts class, particularly if you keep arthropods as pets. She's given squeaks of agony, just to drive the point home, and Crouch!Moody is lying when he says her bite is lethal; whip spiders are gentle, timid, and completely harmless.
This entire scene is hard to watch, especially on subsequent viewings with all of the information.
Neville's reaction to Crouch!Moody using the Cruciatus Curse. You can see upon a first watch that seeing the spell used affects him for some reason, and it's to the point that Hermione literallyscreamsat Moody to stop. (Also, if you look in the background, you can see Seamus cringing and Hannah visibly gulping back tears.) Note that no one knows why it makes Neville especially uncomfortable yet, but Neville's reaction is just that disturbing. We find out later, of course. No doubt Neville was imagining his parents in place of that screaming spider, just moments before the curse caused them to lose their minds permanently. And we later also find out that the person we think is demonstrating this for 'educational' purposes was one of the people responsible, and subjected Neville to what amounts to its own brand of psychological torture, just to come off as friendly and caring minutes later so he could start the process of manipulating Neville for his ends. Barty Crouch Jr. was something of a Tragic Villain in the books. In the movies, he's just a full-blown bastard and subsequent watches of this scene really drive it home.
Due to the changes in Barty Crouch Senior and Junior, Karkaroff's testimony becomes this from Senior's point of view. Imagine being a father, and finding out that your son is not only part of the organization of genocidal fascists you've been waging war against for years, but that he's (partly) responsible for one of its very worst atrocities. Roger Lloyd-Peck's expression really does encapsulate the amount of horror and heartbreak any parent would feel in that situation.
