From the Book:
- Harry finding out about Neville's parents, and how they were cursed into insanity by the Death Eaters. It gets even worse when he gets to meet them at St. Mungo's in the next book and see how bad it is. When Dumbledore is describing it, Harry notes a bitterness in his voice he doesn't normally hear from the man.
- Harry mentions that it's Voldemort and his followers' fault for destroying families: mentally shattered Neville's parents, implied to have hurt one of Hannah Abbott's parents, killed Moaning Myrtle, ruined the Crouch family, killed most of the Tonks family, forced the Malfoy family to be separated, and killed Harry's parents, godparent, and James's friends.
- Harry thinking about his relatives never hugging him, like a mother would, when Molly hugged him. Not to mention that all the while, Harry 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 genuinely cared about his well-being that the concept 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.
- Cedric's father, who acted like a pompous Jerkass towards Harry in the book, didn't take the Triwizard winnings and also let him know that he doesn't blame him for Cedric's death.
- Dumbledore's speech at the end eulogizing Cedric. Cho crying 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.
- When Barty Crouch, Jr.'s past is revealed, even though he's done quite a few bad things, you can't help but cry (especially when he's on trial when you find how neglected he was by his father, whom later disowned him and put him under the imperius curse. What makes it worse was when he was given the dementor's kiss .
- When dead Cedric 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..."
- 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 killing him from 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 says "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 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...
From the Film:
- 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.
- Cedric's father screaming and sobbing "That's my son! That's my boy!" in utter agony, then rushing over to the body and bawling over it, screaming in pure despair and horror. Amos's despair should hit fathers pretty hard.
- And Dumbledore's eulogy for Cedric. Not just because it's sad, but because Kloves's version of the speech is nowhere near as good as Rowling's.
- The scream of pure terror Fleur does when seeing the corpse of Cedric.
- The shot of Cho's crying face as she stares at Cedric's body. Say what you want about her in the next film, but in that one brief moment Katie Leung showed she can really act. Really, just pretty much everyone's reactions in that scene (particularly Hagrid as he gradually realizes what's happened after Fleur's scream) illustrate perfectly why it's the most heart-wrenching scene in the whole film series.
- 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's it's not real.
