AN: Here we have it, this scene is the whole reason I started writing this story!

***DNCMY1***

In the end, it only took the dragon reserve two days to dispatch some people to collect Norbert. They even brought papers to prove they had the right to transport a newly hatched dragon. Hagrid met them just on the boundary of the Hogwarts grounds, so they wouldn't have to enter the wards, and they came at dinnertime, when almost everyone was inside eating. They left by broom, the crate with the baby dragon suspended between them, because other means of magical transportation played havoc on a dragon body.

As far as Donna was concerned, they didn't come a day too soon. She didn't like Malfoy's smirk every time he saw them, but then she didn't have to like it. If he was that confident he could get them into trouble, he'd only be more likely to take their bait.

Her plan was simple enough. As soon as they knew the exact date the dragon handlers would arrive, she and Hermione faked a letter with the most ridiculous plan they could come up with, involving transporting the dragon in a crate to the top of the astronomy tower. They set the date for three days after the actual pick-up.

Then it was just a matter of Harry talking to Neville about 'that letter about you-know-what in Hagrid's hut' within hearing distance of Malfoy. That same evening, Neville reported the fake letter gone.

At that point, the prank was out of their hands. Either Malfoy didn't take the bait, in which case nothing happened, or he'd use the information to get them into trouble, and come away with a bad experience himself.

Hermione had even unearthed a charm that would erase the letter as soon as the date mentioned in it had gone, so even if he tried to use that as proof of their wrongdoing, all he'd have left would be a bit of pristine parchment. The only risk was that he could show the letter to a professor beforehand, but that was a risk they were willing to take.

They made sure to keep visiting Hagrid even after Norbert had been picked up, to give the impression the dragon was still there. They used the time to console the half-giant to his loss, and only a little bit to pepper him with questions about Fluffy and the other protections.

On the date mentioned in their letter, Malfoy kept smirking at them, but no professor confronted them, so they were reasonably sure he was going to do something stupid.

This was confirmed the following morning, when Malfoy was sitting alone at the Slytherin table, sporting the mother of all sulks, while the hourglass showed his house had lost 20 points.

As it turned out, he had tried to catch them singlehandedly. McGonagall had found him wandering near the astronomy tower, or so the rumour mill went. They shared a good laugh when Malfoy glared at them like his predicament was their fault. Donna waved cheekily at him, causing his glare to intensify to murderous levels, before turning to her own breakfast. That'd teach him to steal other people's letters – fake or otherwise.

By the time she'd finished eating, most of the Hall had filled up, although only a few teachers were keeping an eye on things. When she rose from her seat, she was suddenly confronted by Malfoy.

"This is all your fault, Noble!" he hissed. She raised her eyebrows at him, unimpressed.

"Is it? I forced you to get up in the middle of the night for a little midnight stroll, did I? And worse, get caught doing it? I thought Slytherins were supposed to be good at sneaking? Looks like you might be an exception..."

"Argh!" he spat. "You stupid mudblood!" Judging from the gasps behind her, he'd just called her something quite bad, but since she had no context for the word, she didn't feel insulted. Instead, she started grinning, as the word jogged the memory of a song so ingrained in mundane culture, it still popped up all over the place even decades after it was first released. And best of all, it was from the eighties, meaning...

"Oi! Thomas!" she called. And then she stomped her foot twice, and clapped her hands once.

Dean started laughing and followed suit. Stamping his feet wasn't so easy while sitting down, but instead he hit the table with his hands. Beat beat clap, beat beat clap. By the fourth time, more people were taking up the rythm – all of them muggleborn or muggleraised. The wizard-raised students looked on in confusion, unsure what was happening.

Still grinning, Donna turned to Malfoy and started singing, while she approached him and patted him on both cheeks.

"Buddy, you're a boy, make a big noise

Playing in the street, gonna be a big man someday,

You got mud on your face, you big disgrace,

Kicking your can all over the place, singing..."

And just like that, half of the Great Hall joined her song.

"We will, we will, rock you!"

If the teachers had not noticed the song before, they certainly did now. However, with every table showing stamping and clapping students, some of whom had jumped up on their benches so they could make more noise, they had some trouble locating the source, giving Donna time for the second verse.

"Buddy, you're a young man, hard man,

Shouting in the street, gonna take on the world someday,

You got blood on your face, you big disgrace,

Waving your banner all over the place."

By this time, McGonagall and Snape had found them, and come to investigate what the disturbance was about, although they couldn't immediately ask what was happening, as the chorus of "We will, we will, rock you!" reverberated through the Hall and drowned out anything they might say. In fact, by now the beat had been taken up by some of the more progressive purebloods.

Snape was the first to lose his patience, since the headmaster didn't seem inclined to put a stop to the spectacle – and in fact was tapping along to the beat with a smile on his face.

The bang that issued from Snape's wand served its purpose in that the beat and the song both died away, although the students that were already standing up didn't sit back down, intent on watching the follow-up. It was rare enough that a disturbance took up the whole Hall like this, and they wanted to know the end of it, too.

"Miss Noble, what is the meaning of this?"

She looked innocently up at him, a feat made easier by her little de-aging trick. Nobody could pull off innocent like a not-quite-teenager.

"I was just... singing a song, sir. Oh, and promoting inter-house unity, since that seems rather low on the staff's list of priorities."

"And harassing one of your fellow students?" he asked menacingly.

She couldn't find it in herself to be afraid of his tough act. Wherever his loyalties might lie, whether he was the would-be thief or the Stone's protector, he was a bully, and he paled in comparison to the bullies that the Doctor made it his life's work to fight. Even within her own lifetime, without factoring the Doctor's memories, she'd fought against the supremest bully of them all, Davros... fought him and won. Severus Snape quite simply did not compare.

"Harassing, sir? Oh no, I would never. See, as I understand it, harassment implies going out of your way to bother another student with unwanted attention. Which would you say is closer to that definition, the student who sings a song that many people join into of their own free will? Or the one that goes to a table not his own, in order to call someone a mudblood?"

Snape looked towards Draco for a moment, brows drawn and lips pinched. At least the boy looked abashed, although that might still be an after-effect from being the subject of Donna's song. Snape pinched the bridge of his nose for a moment, then shook his head.

"Detention, I think, miss Noble."

She doffed an imaginary hat at him, but was spared a reply by McGonagall's voice.

"And for mister Malfoy too. I will not tolerate the use of that word in this school."

Snape looked sharply at her but did not comment, so Draco withdrew tactfully back to the Slytherin table while Donna and her friends made their way out of the Great Hall. She could feel the greasy git's disapproving gaze boring into the back of her head. She didn't care, since everywhere in the Great Hall there were muggleborns explaining to their pureblood friends who Queen were and why they really should give them a try if ever they had the chance. She counted this a definite win.

"Worth it!" she laughed when they were finally outside.
