What are the most significant instances of romantic jealousy in the Harry Potter series?

'Told you,' said Hermione succinctly. 'Sooner you ask someone, sooner they'll all leave you alone and you can –'

(DH)

'No!' she said angrily, and stormed away, leaving Harry alone and ankle-deep in snow.

'It's a lot colder where he comes from,' said Hermione. 'I suppose it feels quite warm to him.'

The girl picked up the dish and carried it carefully off to the Ravenclaw table. Ron was still goggling at the girl as though he had never seen one before. Harry started to laugh. The sound seemed to jog Ron back to his senses.

‘How's it going?' Harry asked Ron, sitting down and opening a bottle of Butterbeer. Ron didn't answer. He was glaring at Hermione and Krum, who were dancing nearby. Padma was sitting with her arms and legs crossed, one foot jiggling in time to the music. Every now and then she threw a disgruntled look at Ron, who was completely ignoring her.

‘Ho ho,’ said Hermione in a bored voice. ‘He said Harry knew how to do stuff even he didn’t, and he was in the final year at Durmstrang.’

‘Yeah. Well, she asked me to, so I thought I would. D’you want to come with me? She said it wouldn’t matter if you did.’

I tried to collect most of “romantic jealousy scenes” from the books. But not all. For example, not all Hermione/Ron/Lavender, Cho/Harry/Hermione or Harry/Cho/Cedric scenes were listed here. Some scenes I personally don't count as romantic jealousy for specific reasons, like Ron's reaction to Lockhart, which was similar to Harry's reaction to him, but just wasn't as often voiced from Harry’s end due to the different emotional openness between Harry and Ron. Or Ron's reaction to Hermione's comment that "Harry's not a bad kisser", since logically it would have made sense to clarify her words here (but he did frown, which could also be an indicator of mistrust or jealousy), as well as the polyjuice potion scene in DH - but those two moments are open to interpretation for everyone. I personally think it was more of a confusion at this point. In fact, you could also add the scene with Hermione getting threatening letters over Skeeter's article about her affair with Harry in GOF. But I don't even know or remember the names of those characters. Ginny's potential jealousy of Fleur (and Harry) in HBP is highly debatable. Ron's irritation with Cedric (or rather with the fact that Hermione finds him handsome) in GOF can be considered semi-jealousy, since the narrative supports irritation about Cedric not only from Ron’s end but from most boys, it’s more of a boyish envy. And because it didn't even become a catalyst for him to starting to "see her in a new light" before the ball. Another scene in HBP, where Hermione teases Ron about his failure to make Rosmerta laugh, is also more of a statement of fact than jealousy. The scene where Lavender leaves angrily after the Quidditch tryouts in HBP always confused me, but the reasons for this were left off-page (she had no particular reason to hope for anything from Ron at this point and he did play well and was happy, I'm not sure if this was just a reaction to Hermione's joy at this point), so I don’t want to get into speculation. The idea that Hermione was subconsciously trying to keep Luna away from Ron in book 5 is interesting, but it's also mostly speculation. And no, Hermione wasn't jealous of Cho or Ginny. No, Harry wasn't jealous of Ron because of his closeness to Hermione in DH either. Snape and James's attitude towards each other clearly has an undertone of jealousy over Lily. I would say Snape is the most romantically jealous character in the books due to his decades of malice. But it's all very multi-layered in his case. I also may not remember some moments.

Ron's ears had turned bright red again. After glancing at Krum's invitation as if he did not believe a word of it, he said, much too loudly, “how come you're here?”

Oh, come on, Harry,' said Hermione, suddenly impatient. 'It's not Quidditch that's popular, it's you! You've never been more interesting and, frankly, you've never been more fanciable.'

"Yeah, it is!" said Ron, just as angrily. "D' you think I want people saying my sister's a —"

He hadn't mentioned Viktor Krum since the ball, but Harry had found a miniature arm under his bed on Boxing Day, which had looked very much as though it had been snapped off a small model figure wearing Bulgaria Quidditch robes.

She looked too fierce to argue with at that moment, so Harry dropped the subject of Ron and recounted all that he had overheard between Malfoy and Snape.

He glanced at Cho and then back at them. “Listen, I know it’s not much of a lead,

2. Yule Ball. The main catalyst for Ron and one of the most popular “jealousy” scene. Definitely not the best moment for his character.

'Don't call him Vicky!' Hermione jumped to her feet, and stormed off across the dance floor, disappearing into the crowd. Ron watched her go with a mixture of anger and satisfaction on his face.

"You'd better hurry up!" Ron called loudly after her. "The carriages'll be here in a minute!" He let Harry keep a watch for the carriages, however, and spent the next few minutes craning his neck over the crowd to try and see what Krum and Hermione might be up to.

The door behind them burst open. To Harry's horror, Ron came in, laughing, pulling Lavender by the hand. "Oh," he said, drawing up short at the sight of Harry and Hermione.

'Well, goodnight, Harry,' said Hermione, though it was only seven o'clock in the evening, and she left for the girls' dormitory without another word.

12. Obvious jealousy on Hermione's part because Ron is “drooling” over someone else.

‘He didn’t only want to be your pen-pal,’ said Ron accusingly.

(OOTP)

19. Just a display of jealousy on the part of Dean (who had recently been dumped) and Romilda, who had her own plans for Harry.

The honest answer was "yes," but he did not want to give it. However, Ron seemed to gather the worst from the look on Harry's face.

'I thought maybe, you know, over Christmas –'

(…)

Harry stared at her, utterly bewildered, as she seized a frilly napkin and dabbed at her shining face with it.

'Of course she isn't!' said Hermione tartly. 'I don't see anyone else gaping at her like an idiot!'

“What are you doing?”

'I didn't feel anything,' said Harry, ignoring this interruption. 'But I don't care about that now –'

but I’m going to go and look at this statue, at least find out what the diadem looks like. Wait for me here and keep, you know — the other one — safe,”

Hermione slid off the desk. The little flock of golden birds continued to twitter in circles around her head so that she looked like a strange, feathery model of the solar system.

‘Cho?’ he said weakly, wishing Roger would seize his girlfriend and start kissing her again to stop her goggling at him and Cho.

'Er ... listen, d’you want to come with me to the Three Broomsticks at lunchtime? I’m meeting Hermione Granger there.’ Cho raised her eyebrows.

(…)

3. Another major outburst of jealousy from Ron, this time fuelled by serious insecurities and resentment towards himself for allowing his expectations to get too high after Hermione's invitation to the Slug Club party.

"Gerremoffme!" he yelled, but with one last look of vindictive fury, Hermione wrenched open the door and disappeared through it. Harry thought he heard a sob before it slammed.

Ron changed tack at the speed of light. 'Then he's hoping you'll help him find out what his egg means! I suppose you've been putting your heads together during those cosy little library sessions –'

27. At first point Ron's jealousy is clear, it built precisely on Hermione's reaction towards Harry.

Ironically, Krum was standing right behind her at that moment. After confessing his feelings.

'I expect your trainers are too small, Won-Won,' said a voice behind them, and Hermione stalked past, smirking.

(HBP)

‘Well – I have talked about it,’ Harry said in a whisper, ‘to Ron and Hermione, but –’

(...)

24. Ginny knows very well who shouldn't be left alone with Harry.

Hermione looked at him in surprise. 'What's up with you?' she said.

'She's a Veela!' he said hoarsely to Harry.

“Hermione?"

(...)

“That's Xenophilius Lovegood, he's the father of a friend of ours,” said Ron.

11. Another interesting scene from book 4. It's hard to say whether Hermione wanted to provoke a reaction from Ron and "avoiding his eyes", but it hardly seemed like there was any need to provoke anything.

Cho had got to her feet, but Ginny said rather fiercely, “No, Luna will take Harry, won’t you, Luna?”

'He's from Durmstrang!' spat Ron. 'He's competing against Harry! Against Hogwarts! You – you're –' Ron was obviously casting around for words strong enough to describe Hermione's crime, 'fraternising with the enemy, that's what you're doing!'

“Ah, they are together now?” asked Krum, momentarily distracted.

"What were you doing up there with her!" shrieked Lavender Brown, staring right through Harry at Ron and Hermione emerging together from the boys' dormitories. Harry heard Ron spluttering behind him as he darted across the room away from them.

(...)

'What does she see in Krum?’ Ron demanded, as he and Harry climbed the boys’ stairs.

25. After confessing his feelings for her, Viktor received no reciprocal attention from Hermione during the Second Task.

‘Oh, you’ll talk to Hermione Granger!’ she said shrilly, her face now shining with tears. Several more kissing couples broke apart to stare. ‘But you won’t talk to me! P – perhaps it would be best if we just ... just p – paid and you went and met up with Hermione G – Granger, like you obviously want to!’

"Is Hermione Granger still visiting him?" Lavender demanded suddenly.

(...)

"After he'd got rid of his shark's head. Madam Pomfrey gave us both blankets and then he sort of pulled me away from the judges so they wouldn't hear, and he said, if I wasn't doing anything over the summer, would I like to -"

Hermione looked as though Ron had slapped her. When she spoke, her voice quivered. 'For your information, he hasn't asked me one single thing about Harry, not one –'

And then there was also resentment at her lack of attention towards him. Sometimes fears of showing interest lead to serious insecurities on the other side.

Ron gagged on a large piece of kipper. Hermione spared him one look of disdain before turning back to Harry.

23. Hermione isn't particularly keen on helping Ron win over another girl, which is very different from her approach to Cho and Harry.

The fact that Harry hadn't noticed her counter-attempts to make him jealous only made her reaction worse.

Ron gave her a withering look. 'Viktor?' he said. 'Hasn't he asked you to call him Vicky yet?'

'You haff a water-beetle in your hair, Herm-own-ninny,' said Krum.

He brushed some of the fake snow off Hermione's shoulder Lavender burst into tears. Ron looked immensely guilty and turned his back on her.

Ron wrenched the chain from over his head and cast the locket into a nearby chair. He turned to Hermione.

Fleur swooped down on him, too, and kissed him. Hermione looked simply furious..."

Harry turned away from Ron, who did not look like he would be surfacing soon, just as the portrait hole was closing. With a sinking feeling, he thought he saw a mane of bushy brown hair whipping out of sight.

"Yeah, I think so. Well, they're friends, aren't they?" said Harry uncomfortably.

'Ron reckons I should just hang back after Potions this afternoon ...'

'And it doesn't hurt that you've grown about a foot over the summer, either,' Hermione finished, ignoring Ron.

26. Hermione easily reacts to Fleur whenever she shows any attention to Ron.

He found her in the first unlocked classroom he tried. She was sitting on the teacher's desk, alone except for a small ring of twittering yellow birds circling her head, which she had clearly just conjured out of midair. Harry could not help admiring her spell-work at a time like this.

(...)

Hermione noticed his tone of voice, and frowned. 'He's really nice, you know,' she said. 'He's not at all like you'd think, coming from Durmstrang. He likes it much better here, he told me.'

He hurried off behind Hermione, his voice tailing away feebly.

Harry tried not to watch Cho and Cedric; it gave him a strong desire to kick something.

But Ron ignored Harry too. 'Why don't you go and find Vicky, he'll be wondering where you are,' said Ron.

(GOF)

‘Oh... well... that was nice of her.’

"No," said Harry very firmly.

"He asked me right after he'd pulled me out of the lake." Hermione muttered.

(DH)

He had no idea what to say to her. He was just wondering whether there was any chance that she had not noticed Ron, that she had merely left the room because the party was a little too rowdy, when she said, in an unnaturally high-pitched voice, "Ron seems to be enjoying the celebrations".

4. Harry tries to convince himself that he's not falling in love with his best friend's sister. And it's not going very well.

‘You’re meeting Hermione Granger? Today?’

(GOF)

"Yeah," said Ron, looking extremely hopeful, "yeah, a bit –"

(HBP)

(GOF)

“What do you mean?”

'He's mad!' said Harry, staring at Krum's dark head, as it bobbed out into the middle of the lake. 'It must be freezing, it's January!'

"I expect 'nothing's' in the back getting more firewhisky," said Hermione waspishly.

"Well, what's so impressive about that?" whispered Ron, who for some reason looked annoyed. "You are the best in the year - I'd've told him so if he'd asked me!"

5. Lavender's possessiveness towards Ron is quite understandable, as Ron wasn’t honest with her and brave enough to end a meaningless relationship. His detachment only fueling her insecurities.

"Yeah," said Harry, "because were friends." He couldn't quite believe he was having this conversation with Viktor Krum, the famous International Quidditch player. It was as though the eighteen-year-old Krum thought he. Harry, was an equal - a real rival -

6. Cho's baseless jealousy, which was triggered by Harry's tactlessness at that moment.

'Everyone knows you've been telling the truth now, don't they? The whole wizarding world has had to admit that you were right about Voldemort being back and that you really have fought him twice in the last two years and escaped both times. And now they're calling you the “Chosen One” – well, come on, can't you see why people are fascinated by you?'

'Yeah, but there's still the giant squid,' said Ron. He didn't sound anxious – if anything, he sounded hopeful.

He had known Ginny for years now… it was natural that he should feel protective… natural that he should want to look out for her…want to rip Dean limb from limb for kissing her…no… he would have to control that particular brotherly feeling.

"Oops!" said Lavender, and she backed out of the room, giggling. The door swung shut behind her. There was a horrible, swelling, billowing silence. Hermione was staring at Ron, who refused to look at her, but said with an odd mixture of bravado and awkwardness,

(HBP)

Cho sprang to her feet. The whole tearoom was quiet and everybody was watching them now.

Krum had come to say good-bye to Hermione. "Could I have a vord?" he asked her.

Unlike in the film, this was not the reason for his departure, but the conclusion.

(GOF)

1. The most explosive “romantic jealousy” scene in the books. Especially when something like this is done by a character like Hermione, who usually relies on logic and intellect - it becomes clear how strong her resentment and jealousy is in this moment.

"Fleur bent down, kissed Harry twice on each cheek (he felt his face burn and wouldn't have been surprised if steam was coming out of his ears again), then said to Ron, "And you, too – you 'elped –"

9. Serious possessiveness on Ginny's part. Even eleven year old girls can't stare at her ex-boyfriend.

(…)

“I get it. You choose him".

Hermione stared at him, then at Harry, who shrugged.

22. Book seven and Ron still reacts to Krum. Although there were reasons for this.

Ron said nothing, but looked disgruntled.

"Nothing," he said. But Krum glowered at him, and Harry, somehow struck anew by how tall Krum was, elaborated. "We're friends. She's not my girlfriend and she never has been. It's just that Skeeter woman making things up".

(...)

28. Still a lot of resentment and jealousy on Hermione's part at the beginning of Ron and Lavender's relationship.

Harry looked around; there was Ginny running toward him; she had a hard, blazing look in her face as she threw her arms around him. And without thinking, without planning it, without worrying about the fact that fifty people were watching, Harry kissed her. After several long moments—or it might have been half an hour—or possibly several sunlit days—they broke apart. The room had gone very quiet. Then several people wolf-whistled and there was an outbreak of nervous giggling. Harry looked over the top of Ginny's head to see Dean Thomas holding a shattered glass in his hand, and Romilda Vane looking as though she might throw something. Hermione was beaming..."

(...)

"You haff never...you haff not..."

‘Viktor.’

20. Hermione's burning jealousy after Christmas and her “date” with McLaggen.

‘Yeah, but apart from that,’ said Ron, sounding aggravated. ‘I mean, he’s a grouchy git, isn’t he?’

Oh, there are many.

"Oh...yes...all right," said Hermione, looking slightly flustered, and following Krum through the crowd and out of sight.

(GOF)

Harry spun around to see Hermione pointing her wand at Ron, her expression wild: the little flock of birds was speeding like a hail of fat golden bullets toward Ron, who yelped and covered his face with his hands, but the birds attacked, pecking and clawing at every bit of flesh they could reach.

I will also combine these moments from HBP.

"Hermy-own-ninny talks about you very often," said Krum, looking suspiciously at Harry.

Krum grunted. “Vot,” he said, draining his goblet and getting to his feet again, “is the point of being an international Quidditch player if all the good-looking girls are taken?”

What did surprise him was that when Ron drew level with them, Parvati suddenly nudged Lavender, who looked round and gave Ron a wide smile. Ron blinked at her, then returned the smile uncertainly. His walk instantly became something more like a strut. Harry resisted the temptation to laugh, remembering that Ron had refrained from doing so after Malfoy had broken Harry's nose; Hermione, however, looked cold and distant all the way down to the stadium through the cool, misty drizzle, and departed to find a place in the stands without wishing Ron good luck.

"What?" said Ron, dropping his pestle with a loud clunk.

“If she kissed someone like Krum, then she wouldn't even consider Ron as a potential boyfriend”.

Lavender Brown, Harry noticed, glared at Hermione from a neighboring table through very red eyes, and Hermione immediately let go of Ron's arm.

"It's very good already," said Ron in a strangled sort of voice. Fleur smiled at him; Hermione scowled.

(...)

"And what did you say?" said Ron, who had picked up his pestle and was grinding it on the desk, a good six inches from his bowl, because he was looking at Hermione.

16. Harry's first experience of jealousy wasn't described as a "monster in his chest", but it still was pretty obvious.

Harry's dismay, Ron's new aggression did not wear off over the next few days.

Harry, who from Krum's secretive manner had expected something much more serious than this, stared up at Krum in amazement.

"A what?" shouted Ginny, drawing her wand. "A what, exactly?"

(...)

"It's pathetic," said Hermione furiously, striding away from Ron as far as she could go and turning to face him with her arms folded once she had reached the wall.

‘Well,’ said Harry, considering the matter, ‘I s’pose he’s older, isn’t he ... and he’s an international Quidditch player ...’

'Oh, well, if Won-Won thinks that, you'd better do it,' she said, flaring up at once. 'After all, when has Won-Won's judgement ever been faulty?'

'If you don't know,' said Ron scathingly, 'I'm not going to tell you.'

Ron was looking at Hermione suspiciously. ‘You’re not still in contact with him, are you?’

29. Ron doesn't even try to hide his emotions and sometimes it's really funny.

“Come and dance,” he added abruptly to Hermione. She looked taken aback, but pleased too, and got up. They vanished together into the growing throng on the dance floor.

(OOTP)

'No, I can't,' she said flatly. 'So don't even ask.'

"He doesn't mean anything, Ginny —" said Harry automatically, though the monster was roaring its approval of Ron's words.

It's ironic that Hermione ignored Ron herself to shower Harry with compliments, but she's not happy about the attention Ron gets from other girls, even though it makes sense that he would want some attention too.

(HBP)

‘How did you do?' asked Ron, hurrying towards Harry. 'I think I felt something the last time I tried – a kind of tingling in my feet.'

(...)

"And he did say he'd never felt the same way about anyone else," Hermione went on, going so red now that Harry could almost feel the heat coming from her, "but how could Rita Skeeter have heard him? She wasn't there...or was she? Maybe she has got an Invisibility Cloak; maybe she sneaked onto the grounds to watch the second task...."

'Ron, what –?'

(HBP)

'Hermione, can't you –'

Ron ignored this jibe, sipping his drink in what he evidently considered to be a dignified silence. Harry was thinking about Sirius, and how he had hated those silver goblets anyway. Hermione drummed her fingers on the table, her eyes flickering between Ron and the bar.

"Nothing," said Ron, hastily looking away from the bar, but Harry knew he was trying to catch the eye of the curvy and attractive barmaid, Madam Rosmerta, for whom he had long nursed a soft spot.

13. An alternate scene from book 4, with obvious reference to Hermione’s bias, which definitely points to jealousy.

But her face suddenly turned blank; she had just spotted Ron and Lavender who were entwined in the same armchair.

21. A display of possessiveness on the part of Harry, who had already broken up with Ginny at this point.

"This girl is very nice-looking,” Krum said, recalling Harry to his surroundings. Krum was pointing at Ginny, who had just joined Luna. “She is also a relative of yours?”

(GOF)

"But I had my wand hidden up my sleeve," he assured Padma Patil, who seemed to be a lot keener on Ron now that he was getting so much attention and was making a point of talking to him every time they passed in the corridors. "I could've taken those mer-idiots any time I wanted."

"Oh, hello, Harry," she said in a brittle voice. "I was just practicing".

Ron's voice tailed away in mutters, barely audible over the loud crackling of the fire, though Harry thought he caught the words 'Krum' and 'can't complain' again.

'Are you going to ask me to dance at all?' Padma asked him.

He looked around. Fleur Delacour was hurrying up the stone steps into the castle. Beyond her, far across the grounds. Harry could see Hagrid helping Madame Maxime to back two of the giant horses into their harness. The Beauxbatons carriage was about to take off. "We will see each uzzer again, I 'ope," said Fleur as she reached him, holding out her hand. "I am 'oping to get a job 'ere, to improve my Eenglish."

(HBP)

'I'm tall,' said Ron inconsequentially.

So how was your Christmas?'

They returned quite soon. Ron stared at Hermione, but her face was quite impassive.

(GOF)

'She can't complain,' he told Harry. 'She snogged Krum. So she's found out someone wants to snog me, too. Well, it's a free country. I haven't done anything wrong.'

After a few moments he muttered to Harry, “Did you see he's grown a stupid little beard?”

'Oh, right,' said Harry. His insides had come back again. It felt as though they had been filled with lead in their absence. Completely forgetting about dinner, he walked slowly back up to Gryffindor Tower, Cho's voice echoing in his ears with every step he took. 'Cedric – Cedric Diggory.' He had been starting to quite like Cedric – prepared to overlook the fact that he had once beaten him at Quidditch, and was handsome, and popular, and nearly everyone's favourite champion. Now he suddenly realised that Cedric was in fact a useless pretty-boy who didn't have enough brains to fill an eggcup.

But Cho did not sound as though she thought it was nice at all. On the contrary, her tone was cold and all of a sudden she looked rather forbidding.

(GOF)

"Ron, what are you staring at?"

But the smile vanished from his face at once: Viktor Krum had dropped into Luna's vacant seat. Hermione looked pleasurably flustered but this time Krum had not come to compliment her. With a scowl on his face he said, “Who is that man in the yellow?”

Krum looked slightly happier. He stared at Harry for a few seconds, then said, "You fly very veil. I vos votching at the first task."

"Well, you do," said Ron, "but if she jumps out at you unexpectedly, like then..."

Hermione turned to Harry with a radiant expression and whispered, "Did you really tell him I'm the best in the year? Oh, Harry!"

“Are you staying or what?”

(…)

14. A slightly more restrained reaction from Ron, but the jealousy is still clearly felt. An attempt at provocation from Hermione’s side is possible here.

"No, it's just...how did she know Viktor asked me to visit him over the summer?" Hermione blushed scarlet as she said this and determinedly avoided Ron's eyes.

(...)

(GOF)

'No,' said Ron, still glaring after Hermione.

10. One of my personal favorite jealousy scenes. Broke the arm of the Krum’s model figure, seriously?

Harry awoke next morning feeling slightly dazed and confused by a series of dreams in which Ron had chased him with a Beater's bat, but by midday he would have happily exchanged the dream Ron for the real one, who was not only cold-shouldering Ginny and Dean, but also treating a hurt and bewildered Hermione with an icy, sneering indifference.

"Would you call getting poisoned being interesting?" asked Harry.

"Don't you get used to her if she's staying in the same house?" Harry asked.

(…)

‘It’s not like that!’ said Harry, and he was so relieved at finally understanding what she was annoyed about that he laughed, which he realised a split second too late was also a mistake.

'It's hot, isn't it?' said Hermione, fanning herself with her hand.

'Oh, fine,' she shrugged. 'Nothing special. How was it at Won-Won's?'

"Friends, don't make me laugh," said Lavender scornfully. "She didn't talk to him for weeks after he started going out with me! But I suppose she wants to make up with him now he's all interesting…"

People were starting to stare at them.

His pugnacious tone indicated that they were not about to laugh at Xenophilius, despite the clear provocation.

'Ron,' said Harry quietly, 'I haven't got a problem with Hermione coming with Krum –'

'And you've been through all that persecution from the Ministry when they were trying to make out you were unstable and a liar. You can still see the marks where that evil woman made you write with your own blood, but you stuck to your story anyway…'

'Obvious, isn't it? He's Karkaroff's student, isn't he? He knows who you hang around with ... he's just trying to get closer to Harry – get inside information on him – or get near enough to jinx him –'

‘How many other Viktors do we know?’

(…)

Harry glanced at Ron, who was looking relieved that nothing worse had happened.

Ron looked round at her so fast he appeared to crick his neck. Rubbing it, he said, ‘Yeah? What did Vicky say?’

"Good-bye, 'Arry," said Fleur, turning to go. "It 'az been a pleasure meeting you.

(…)

17. Another display of jealousy on Lavender's part, this time less founded (at least in terms of Hermione’s actions).

But this is the turning point in Ron and Hermione's relationship in the series.

The largest number of examples can be found in HBP and GOF.

'It was the Fat Lady who drank a vat of five-hundred-year-old wine, Harry, not me. So what was this important news you wanted to tell me?'

'Who're you going with?'

"I vant to know," he said, glowering, "vot there is between you and Hermy-own-ninny."

“And, of course, you 'ave met my leetle daughter, Gabrielle!” said Monsieur Delacour. Gabrielle was Fleur in miniature; eleven years old, with waist-length hair of pure, silvery blonde, she gave Mrs. Weasley a dazzling smile and hugged her, then threw Harry a glowing look, batting her eyelashes. Ginny cleared her throat loudly.

Harry was finding the Great Hall very hot all of a sudden, even though the ceiling still looked cold and rainy.

Nothing Harry said made any difference. He tried boosting Ron's confidence all through dinner, but Ron was too busy being grumpy and surly with Hermione to notice.

(...)

(HBP)

(...)

‘Krum?’

'Viktor's just gone to get some drinks.'

Harry had the impression that Krum was drawing her attention back onto himself; perhaps to remind her that he had just rescued her from the lake, but Hermione brushed the beetle away impatiently and said, 'You're well outside the time limit, though, Harry ... Did it take you ages to find us?'

(HBP)

(...)

18. Apparently, Rosmerta had plans to start a relationship with a child. Or someone couldn't stand Ron's interest in other girls, even adult women.

Ron, whose hands and forearms still bore scratches and cuts from Hermione's bird attack, was taking a defensive and resentful tone.

"And what did you say?" Ron repeated, pounding his pestle down so hard that it dented the desk.

'Oh – Cedric,' she said. 'Cedric Diggory.'

‘So what if I am?’ said Hermione coolly, though her face was a little pink. ‘I can have a pen-pal if I –’

But she wasn't entirely right about that. As the girl crossed the Hall, many boys' heads turned, and some of them seemed to have become temporarily speechless, just like Ron.

'I'll tell you in a minute,' said Harry. 'Look, Hermione, can't you –?'

'Well, bye,' said Cho, still very red. She walked away. Harry called after her, before he could stop himself.

"Well, I was too busy seeing whether you and Harry were okay to -"

“Ron, no—please—come back, come back!”

Ron said nothing.

‘I’ll see you around, Harry,’ she said dramatically, and hiccoughing slightly she dashed to the door, wrenched it open and hurried off into the pouring rain.

15. One of the key hints about Hermione's feelings in GOF that was completely missed in the film.

"Hi, Harry! Wondered where you'd got to!"

7. Krum's suspicions about Hermione and Harry in Book 4. Hermione's lack of reciprocity only fueled his doubts. And Harry seemed like a logical target at that point.

“Oooh, yes, I’d like to,” said Luna happily, and Cho sat down again, looking disappointed.

"Er... does he?" said Harry.

Dean was looking embarrassed. He gave Harry a shifty grin that Harry did not return, as the newborn monster inside him was roaring for Dean's instant dismissal from the team.

'Who’re you writing the novel to, anyway?’ Ron asked Hermione, trying to read the bit of parchment now trailing on the floor. Hermione hitched it up out of sight.

" ’Arry! "

"You shouldn't leave Lavender waiting outside," she said quietly. "She'll wonder where you've gone". She walked very slowly and erectly toward the door.

“Yeah,” said Harry, suddenly irritated, “and she's seeing someone. Jealous type. Big bloke. You wouldn't want to cross him.”

"What were you going to do, snore at them?" said Hermione waspishly.

‘Go on, leave!’ she said, now crying into the napkin. ‘I don’t know why you asked me out in the first place if you’re going to make arrangements to meet other girls right after me... how many are you meeting after Hermione?’

Harry gave a guilty start and wrenched his imagination away from a corridor in which no Ron intruded, in which he and Ginny were quite alone— "What?" he said confusedly. "Oh…er…"

Fleur was clapping very hard, too, but Krum didn't look very happy at all. He attempted to engage Hermione in conversation again, but she was too busy cheering Harry to listen.

“Er - sort of,” said Harry.

"Oh yeah," said Ron, looking down at his shoulders in vague surprise. "Sorry… looks like we've all got horrible dandruff now…"

(...)

"Yeah… they're—er — really good…" said Harry

When Harry pushed open the tapestry to take their usual shortcut up to Gryffindor Tower, however, they found themselves looking at Dean and Ginny, who were locked in a close embrace and kissing fiercely as though glued together. It was as though something large and scaly erupted into life in Harry's stomach, clawing at his insides: hot blood seemed to flood his brain, so that all thought was extinguished, replaced by a savage urge to jinx Dean into a jelly. Wrestling with this sudden madness, he heard Ron's voice as though from a great distance away.

He returned to the common room half an hour later to find Hermione and Ron in the best seats by the fire; nearly everybody else had gone to bed. Hermione was writing a very long letter; she had already filled half a roll of parchment, which was dangling from the edge of the table. Ron was lying on the hearthrug, trying to finish his Transfiguration homework.

'He's at perfect liberty to kiss whomever he likes,' said Hermione, while the librarian, Madam Pince, prowled the shelves behind them. 'I really couldn't care less.' She raised her quill and dotted an 'i' so ferociously that she punctured a hole in her parchment. Harry said nothing.

Hermione smiled but made a "shhing" gesture, so that they could hear what Slughorn was saying. Ron looked slightly disgruntled.

Harry looked into the corner she was indicating. There, in full view of the whole room, stood Ron wrapped so closely around Lavender Brown it was hard to tell whose hands were whose.
