It was exactly 10:17 and 38 seconds on Saturday.

Liz, Allison, Mary, and Christian were all in the third floor trophy room. They had been waiting for James, Lupin, Sirius and Peter for nearly twenty minutes now, and they were getting a bit pissed off.

"Where are they?" Allison wondered aloud as she looked at her watch.

"I'm gonna kill them!" Mary expressed violently.

"It's all right. They'll be here soon. Probably. Right?" Christian said.

"May I ask you something, Christian?" Mary said. "When was the last time they were on time? Can you remember any appointments they ever did make on time? I can't. Not one!"

"Well, Mary, you don't exactly hold the 'Always On Time' record either," Christian responded with a grin.

"Well, I was on time to this!" Mary replied haughtily. Then she half-smiled. She knew that what Christian said was true. Then her thoughts returned to how long they had been waiting, and she scowled again. "And I'm never this late!"

"Whatever you say."

"I'm serious!"

Suddenly from the other side of the room came the triumphant exclamation, "No, I'm Sirius!"

Sirius, James, Remus, and Peter had just come up the stairs. All four of them looked nervous. Peter was (yet again) wiggling his annoying little arse around.

"Besides," he added, smiling, "when are you ever serious?"

"You're one to talk!" Mary answered.

"So are you!"

"And that wasn't even a good joke. 'Oh, I'm Sirius, haha, I'm so funny.' Never heard that one before!"

"Deep down, I know you think—"

"You're late!" Liz interrupted. "Why were you so late? We said 10! Not 10:30! Ten! Is this too difficult a concept for you?"

"Well, we—"

"I don't care," Liz said. "So, we all know why we're here. To become… er… transgenderal."

Sirius said, "Oh boy! It's my dream come true. Can my name be Lucy?"

The others stared at him in amusement. James said, "No, I want my name to be Lucy!"

Sirius grinned. "Are you sure you don't want it to be Lily?"

James turned very red. "Hey!"

"Just asking. But maybe you should think it over."

"Hmph."

"Can we begin…" Liz asked. Nobody paid attention.

"You're so mean to me," James said to Sirius. Meanwhile, Christian and Mary had started a conversation with Remus about what pranks they had planned for the Slytherins that night.

She tried again. "Please can we just do this…" Again, no one listened.

Then Liz got mad.

"WOULD EVERYBODY JUST SHUT YOUR PIEHOLE!"

Liz's voice echoed on the walls in an astonishing (and somewhat amusing, if you weren't the one being screamed at) display of brutality. All seven students of her friends stared in silence at the usually good-tempered band geek. "Thank you."

"Is there… something you need to say?" Christian asked Liz.

"Yes. Can we just get this over with? I'm no more keen on being a member of the opposite sex than anyone, but if we can just hurry up and do it…"

All eyes were on Liz. Everyone was completely still. Peter wasn't even wiggling his butt around.

"Why is everybody so quiet?" Liz asked innocently.

"Uh… never mind. Let's just go," Allison said.

"Okay then. Well, the easiest way to do this would probably be for everyone to pair up with someone, and just change them," Liz suggested.

Everyone did so. Liz paired up with James, Mary with Remus, Sirius with Allison, and Christian got stuck with Peter.

"OK, GO!"

A cacophony of "Mentrigliosa!" and "Maletesnic!" ensued, along with eight blue beams of light. When it was over, the eight friends beheld a supremely disconcerting sight.

Standing right in front of each one… was him or herself.

(A/N: I'll refer to each person as who they actually are, then put a slash , then put the new body they're in. Example: Sirius/Allison is Sirius in Allison's body.)

"AAAAAAH!" Mary/Remus shouted.

"EEEEEEEEEEEEE!" Sirius/Allison squealed. "Whoa. What was that? I… I squeaked!""

"That, Sirius," Christian/Peter said, "was your feminine instincts kicking in."

"I have a question," said Allison/Sirius said. "Why didn't our voices change? I mean, Sirius… well, Sirius 'eeped', but our tones and pitches weren't altered at all. Our voices sound exactly the same as before."

"The spell is only for appearance. Only your physical appearance changes. Not your mind, voice, anything else," Remus/Mary said.

"Ah," Allison/Sirius said.

"If I were you," Mary/Remus said to Allison/Sirius and Liz/James, "I'd be worried about those two having your bodies."

The two girls—well, now guys—realized what they meant, and went over to Sirius/Allison and James/Liz.

"You had better not… do anything, you hear? If you do, I'll kick your—posteriors."

"Ooh, Allison, is that a threat?" Sirius/Allison asked mockingly.

Allison/Sirius put her face no more than an inch away from Sirius/Allison's, looked him straight in the eye, and said in a menacing voice, "Yes."

"Oh." Pretending to be unruffled, as soon as Allison/Sirius turned around, Sirius/Allison slowly backed away. He whispered to James/Liz, "Am I that tight?"

"No," James/Liz said.

"Oh, good."

Meanwhile, in a different part of the room, the girls-now-guys were discussing their predicament.

"Why'd I get stuck as annoying old Wormtail?" Christian/Peter whined.

"Hey, when you complain like that, you actually sound a lot like Peter," Mary/Remus said cruelly.

"What! That's an insult!"

"Sorry, Pete—uh, Christian," Mary/Lupin replied.

"If you don't stop calling me Peter, I'll put a hex on you!" Christian/Peter warned.

"Well, I'll put Veritaserum in your drink—and then send you to the guys! Well, girls, now." Mary waved her wand at Christian threateningly. See, all of the girls-now-guys knew that Christian had a deep love for—well, one of their friends, anyway.

"I'll fight you!" Christian challenged.

"Whoa, Christian. Somebody's having a testosterone rush…" Mary laughed.

Christian automatically responded with the amicable insult they always used on each other. "Well, you're a man!"

"Well, yes, Christian, I am."

Christian started to say, "What—" then realized what Mary/Remus was talking about. "Okay, never mind. Sorry."

"Oi! EVERYBODY! C'mere!" Christian/Peter called. Once everyone had assembled, she said, "Okay guys, it's about 10:45. This little…adventure…will end at 10:45 p.m. Let's say we'll meet in—um—well, here works. I trust you can all get out of your dorms and here safely, even if it is after curfew?" She said this as if talking to everyone, but everyone knew that she was really talking to Peter/Christian.

Everyone but Peter/Christian nodded. However, after seeing everyone else consent, Peter/Christian turned red, then quickly nodded. He gulped audibly.

"Well, now that that's settled, everyone go." The eight students shuffled out of the room. Everyone in the room was nervous about the day they were about to have. "And don't forget to be the person you are now!"

As everyone left, Allison shouted, "And don't embarrass us!"
