Little Sven the air molecule was happily zooming around the… um… vacuum of space in the Great Hall at Hogwarts, bumping into other air molecules and apologizing whenever he did. He saw all the students pile into the Great Hall when he did, and remembered his mother always cautioned him never to stay in the Great Hall when people were there, especially if they were going to serve food. He never thought to ask why.

When he saw Serendipity come in, he froze, just like all the people in the Hall. She was beautiful. Sven hovered still like a deer facing headlights, mouth open, not blinking. He watched as she walked down the Hall, not looking at anything else but her. He cried like all the others at her speeches, and cheered when she grew five years older. When Dumbledore finally said, "Let the eating commence!" the danger of the situation finally registered in Sven's brain, and he tried to run away. But it was hopeless. In a painful, excruciating moment, his atoms transformed. Carbon atoms, hydrogen atoms, and oxygen atoms swarmed into him, and soon he became CH3(CH2)16COOH. Sven was now a grease molecule on a piece of bacon.

Other molecules mourned the passing of Sven, who was one of the only air molecules to have independent thought, all five senses, and facial features.

---

'Geez, this bacon is greasy,' thought Harry, chewing on his food and staring at Serendipity.

"I can fix that," said Serendipity. "Nihiloilus!" The grease vanished from the bacon. Ron and Harry stared at her in a mixture of wonder and awe. Harry just gaped, with his mouth open.

Serendipity giggled. Harry hastily closed his mouth, his face turning a deeper red than his robes, which, incidentally, were blue this year, but if they were red, his face would be deeper red. "H-h-how did you know w-what I was thinking?" he stuttered.

"I read minds," Serendipity said simply. Harry understood what she had said, but when he looked at Ron and Hermione, they just looked confused. Harry suspected something.

"Could you say that again?" he asked.

"Certainly. I read minds," Serendipity said.

But this time Harry heard the hissing undertones beneath. He was about to ask her a question, but Ron interjected.

"Do you have a throat problem or something?"

Ron was stupid.

"No, Ron, you fool, Serendipity is a Parseltongue!" cried Hermione. "Right?"

Serendipity giggled, "Yes, I sure am."

Harry gaped again (but by this time he had swallowed the bacon), "But how?"

Serendipity said, "I can show you." She drew out her wand. "Anteimus Tempora!"

A silvery, transparent bubble extended around the four students. Their table dissolved, and the Great Hall vanished. They now stood in a room, with wall-to-wall carpeting and a few sofas. Ron glanced around warily and asked, "What's going on?"

"You'll see," said Serendipity.

"Is this… is this a memory?" Hermione asked. "Where's your Pensieve?"

"Only fools need Pensieves," said Serendipity. Harry was about to argue in favor of Dumbledore but decided Serendipity was ten times better. "We are back in time."

Hermione gasped. "Without a Time-Turner?"

"Only even greater fools need Time-Turners," said Serendipity. Hermione scoffed, and was about to say something, but Serendipity shushed her. "Just watch."

All of the sudden, the wall facing them exploded. Dust flew into the air, and when it settles, bits of debris lay everywhere on the wall-to-wall carpeting. The four heard a scream, and two people ran into the room. The man had mousy-brown hair, thin glasses, and was dressed in office attire. His shoes put dirt on the wall-to-wall carpeting. The woman had short, curly red hair, about as red as the red on Ron's hair. She was a bit chubby, and had a fearful yet protective look on her face. Harry recognized one of the two.

Ron gasped. Hermione gasped. Harry gasped.

"Oh my god!" cried Ron.

"I-i-impossible!" cried Hermione.

"I don't believe it!" said Ron and Harry.

"What's going on?" demanded Ron and Hermione, or perhaps it was Harry and Hermione.

"Somebody explain this!" said Ron and Harry, or Ron and Hermione. Ron definitely said something. It is unclear whether Harry or Hermione said something, but the point is irrelevant.

Of course, they were not speaking of the destroyed wall, the debris scattered on the wall-to-wall carpeting, or the dirt on the wall-to-wall carpeting from the shoe. What they had to say next clearly enunciated the problem.

"Mum," whispered Ron.

"Father," whispered Hermione.

And sure enough, the two people standing there, glancing around, were none other than Molly Weasley and Henry Granger. Serendipity, of course, had known this from the start, which is why she had muttered under her breath, "Desinere!" Until she said the companion spell, the scene before them would be trapped in a time loop of one second. She waited patiently until the three had finished making their revelation. Then she muttered, "Incipere!" and the scene restarted. She smiled grimly and watched.

All of the sudden Voldemort burst into the house. He stared at the wall-to-wall carpeting in distaste, and turned to the two. He shouted, "Get out of my way, bitches!" and stormed out of the room. The bubble containing the four teenagers followed.

They entered a small room, with white laminated tile flooring. Voldemort stormed in. Only a small wooden crib stood there, and the four could not see if there was anything inside it. "YOU!" Voldemort cried. "I'll- I'll…"

Harry, Ron, and Hermione watched in wonder (Serendipity was looking at the white laminated tile and admiring the handiwork.) as the silhouette of a wand rose up, and the voice of a baby said, "Abada Kedaba!" A strong green light rose from the tip of the wand and directly attacked Voldemort. As Harry watched in a new understanding, Voldemort cried out and fled.

Serendipity said, "Incipere!" again and the scene dissolved back into the Great Hall. The bubble disappeared and the voices of all the chattering students and teachers filled their ears. Harry, Ron, and Hermione sat; they were pale, waiting for an explanation.

"Unfortunately, I had a cold that day," said Serendipity. "The spell was not as powerful as it could've been, so Voldemort did not completely die. I regret it to this day. This is, incidentally, also why I speak Parseltongue. The reading minds thing is just because I'm so special. Also I can fly."

"C-couldn't you go back and change it?" asked Ron, only beginning to comprehend the scene.

"No, of course not, because-"

"Because time is set in stone and cannot be changed; fate and destiny always prevail," said Hermione matter-of-factly.

"No, because it would end the story right here," said Serendipity.

"So… so you're the Girl-Who-Lived?" asked Ron in wonder. He was only understanding this now because he was stupid.

"What?" cried Harry, "I thought I was the Girl… er, Boy-Who-Lived!"

"No, Harry, you idiot, when Voldemort's spell rebounded on him in your situation he just got a mild paper cut on his finger. But it was kind of annoying, so now he hates you," said Hermione. Changing the subject, she continued, "I can't believe I'm sitting next to the Girl-Who-Lived."

"But… but… five whole years of people staring at me, being written about in the paper, being a famous student, Voldemort trying to kill me, and the prophecy! What do you mean, a 'mild paper cut'? I'm Harry Potter! I'm the Boy-Who-Lived, dammit! Pay attention to me!"

"Yeah, whatever." Hermione leaned over to Serendipity. "And those spells? How did you learn them? I've never heard of them before."

"Oh, I invented them," Serendipity said. "When I was two."

Harry seethed, refused to be part of the conversation anymore, turned back to his meal, and thought crossly, 'This bacon needs more grease.' ("Noooo!" cried Sven, who had just turned back into an air molecule.)
