'It was a rainy Saturday at Hogwarts School of Witchcraft and Wizardry. The Gryffindor Common Room was filled with bored and restless students lounging in chairs or on sofas, chatting idly. Harry, Ron, and Hermione were seated in the most comfortable armchairs close to the fire. They were joined by Fred and George, and a lively conversation was soon underway.

"It's not possible," Hermione said firmly.

"Hang on," said Harry, "haven't you done it?"

"Yes, but that was only within the space of a couple hours," Hermione explained. "They're talking about going back years. Decades, even. It simply isn't possible."

"Sure it is!" said George.

"Prove it."

"Well, Fred and I have time-traveled loads of times, haven't we?"

"Sure, we do it all the time," Fred agreed.

"Liars," said Hermione.

"I wouldn't call it lying, exactly," said George, "we're just creatively arguing."

"It can't be all that difficult," Fred continued. "All you'd have to do is wave your wand and mutter the right words."

"Well, maybe it's not that easy," said George.

"Have some faith, would you?" Fred took his wand out of his pocket. "Watch: Gesundheit!"

Harry promptly disappeared.

"Huh," said George. "I guess it is that easy."

Harry blinked. He was still in the Common Room, but it was occupied by completely different and unfamiliar people.

"Fred? George?" Harry said cautiously as he looked around, hoping it was only an illusion. "Hermione?"

"No, but close enough," answered a boy with messy black hair. He was seated at a nearby table with two other boys. "I'm James, and this is Sirius and Remus. Where'd you come from?"

"You're…I'm…" Harry fumbled for words. "What's going on?"

"Well, mate, it sounds like you've had a rough day," said Sirius. "Why don't you sit down and tell us about it?"

Harry obliged. "A few of my friends were discussing time travel, and one of them thought it was possible but the other one thought it wasn't-"

"It is, you know," said Remus.

Harry gave a short laugh. "I know. But Fred and George decided to prove it, so they made up some ridiculous spell and-" Harry paused in his explanation as an incredibly attractive red-haired girl descended the stairs to the Common Room. The other boys followed Harry's gaze.

"Fancy Evans, do you?" whispered Sirius, who was seated next to Harry. "Better watch out, mate, James has been after her for years."

"Lily Evans?" Harry asked.

"Yeah. How'd you know that?"

"Never mind." Harry dropped the subject. The fact that he had briefly been interested in his mother, even the sixteen-year-old version, made his skin crawl.

"Mind if I join you?" asked Lily.

"Not at all," James replied, placing another chair between his and Sirius'. He pushed it in for Lily as she sat down.

"So, this friend of yours just waved his wand and you were transported back in time?" Remus asked Harry.

"Pretty much," said Harry as he took out his wand to demonstrate. "He kind of went like this with his wand, then said some silly words like Geese in tights!"

Lily and James vanished immediately.

"Oops," said Harry.

Well, how is it? Please review! I should warn you, and you can probably already tell, but this is not a deep and thought-provoking analysis of the mechanics of time travel. If it makes you laugh a couple of times, great. If it doesn't, oh well. Just review and tell me! Thank you! -Luna
