Chapter 4

Sirius groaned as he woke up on the Infirmary's bed. The juice ... something wasn't right. He glanced at the bed beside him and saw Remus was still asleep … knocked out … unconscious … whatever.

"Finally you're awake, Mr. Bl-!" Madam Pomfrey who had just come out of her office, gasped and closed her mouth with her hand when he saw Sirius. She quickly grabbed her wand and muttered some spells that he couldn't quite make them out.

"Merlin …"

"Care to enlight-" he stopped when he realized something was wrong. His voice … it's sort of high-pitched and … girl like.

Madam Pomfrey shook her head and handed him a mirror then she closed her ears for the predictable reaction.

"What the HELL!"

James was stepping into the Infirmary as he heard the voice. He quickly rushed in to find someone was shaking Madam Pomfrey, some … girl.

"Please calm down, Mr … Black."

"Calm down! CALM DOWN!"

"Sirius?"

The black-haired girl turned her head at the voice and soon James found himself looking at the most beautiful girl he had ever seen. Even more beautiful than Lily Evans. Her hair was short and ruffled, but soft. Her eyes were … Sirius'?

"James?" she squeaked. Oh no. Not now. Not now!

She quickly ran into the bathroom and locked the door, leaving James with his mouth hanging open.

He gulped. "Madam Pomfrey, was that …"

"Sirius Black? Yes."

"But … how?"

"My suspicion has been proved right. Least to say, it can turn anyone who drink it into the opposite gender. In this case, it turns Mr. Black into … as you saw."

"They?" then it dawned to him. "Remus!"

The nurse nodded. "Mr. Potter, can I entrust you to coax Mr. Black out of the bathroom and take care of him while I go to inform the Headmaster?"

James nodded dumbly. By the time he heard the sound of the door closing, he averted his eyes to the bathroom door. Slowly, he approached it and knocked on the wooden door.

"Siri?"

"Go away." Came the reply followed by something sounded suspiciously like curses.

"Sirius, you can't stay there forever."

"Oh, yeah? Watch me."

"Sirius, please come out."

"No."

"Siri …"

"Which part of 'no' do you not understand!"

"Sirius, open the door before I blast it off!"

Sirius pondered for a while. James Potter always true to his words and he/she didn't want Madam Pomfrey to get a heart attack when she saw the ruined door. Slowly, Sirius opened the door. "Satisfied!"

"Quite. Come on. We have to-"

"What happened!" Came the panic voice from the other boy-turned- girl.

James smiled. "At least I don't have to break the news to Remus." Sirius only shook his head in desperation.

Albus Dumbledore was smiling so broadly by the time he reached the Hospital Wing that it annoyed the hell out of Sirius. The Headmaster always put a smile on his face but it didn't console him the least bit for someone to laugh at his problem. Their problem. But Dumbledore was the only person they could run to when there were things like that.

Dumbledore himself was amused. He knew the Marauders loved pranks, but to get pranked? Well, that's new.

"I've heard all the details from Madam Pomfrey, so I've arranged everything." He stopped to look at the Marauders, minus one Peter Pettigrew who was off to meet McGonagall for detention, once again and continued, "You two will be introduced as transferred students from Beauxbatons and Durmstrang."

"Transferred students?" they asked in unison.

"That'll explain your presence easily."

"What about their absence … ?"

"If anyone asks, Mr. Potter, just tell them that they're taken to the St. Mungo's for food-poisoning."

"Excuse me, Headmaster, but … do we have to stay in the girl's dormitory?" Remus asked with a tinge of horror in her voice.

Dumbledore's eyes twinkle even more, if that's possible. "Of course, Mr … Lupin. You have to stay in the girl's dormitory."

Sirius gulped. She covered her face with her hands and shook her head. "Why does it have to happen to us?"

Remus smacked his forehead. "The potion! Madam Pomfrey, does it … does it have bluish colour?"

"The potion? Yes, it does." Madam Pomfrey looked intently at the werewolf. "Do you know anything about it, Mr. Lupin?"

"I … it's just …" he looked at his friends and sighed. Then he began telling them about his detention with Snape and Leon's action of taking the potion from the Potion Master's rack. By the time he's finished, Sirius' eyes were in flames.

"I'll kill that bastard!"

"Language, Mr. Black!"

"Or should I say miss …." James hid his smile with his arm but the tone he used betrayed him. That made Sirius' even madder than before, if that's possible. However, before he had the chance to hit James, Madam Pomfrey demanded them to rest and took James to the door with the Headmaster. That saved him from Sirius' wrath, for now.

Sirius was grumbling about anything and nothing when Remus opened her mouth to speak. "What do you think they'll do to Leon?"

"Get him expelled!"

Remus smiled. "We have done worse things than this and we're still here. They won't expel him. They'll punish him though."

Suddenly Sirius eyes lighted up and Remus saw the look that he knew would be there sooner or later but hoped to avoid. The look that always brought them to those troubles. "We can't let Dumbledore-"

"Headmaster."

"-punish him." Sirius finished her sentence, ignoring Remus' interruption. "However, I won't lay him off. We'll get back at him."

Though having predicted he'd say that, Remus had nothing to say except nodding. Sirius lay down on her bed and contentedly drifted off to sleep.

The Great Hall had never been so silent, yet it was when they were introduced to the whole school. Even as girls, with their short hair, it's only about time the others found out so they took another potion that made their hair longer, thus covering their resemblance with their real selves.

Remus' hair was loose and ran past his shoulder while Sirius' hair was even longer and tied in a loose ponytail. They looked different, other than the fact that they're girls now. Peter gaped, the hand holding bread stopped mid-air. James smiled knowingly, ignoring the look on Peter's face and the glare directed to him by Sirius.

Meanwhile, on the other end of the Gryffindor table, there's someone who almost choked on his breakfast. He's none other than Leon Lupin. When he saw the effect of the Veritaserum he asked Edward to slip into their drinks, he knew he made a mistake. Or rather, Prof. Rott made a mistake.

"It's them." Edward whispered.

"Wha-?"

"Sirius Black and Remus Lupin. But you said it's-"

"Veritaserum. That's what I thought. What do we do now?"

"I wish I could answer that, Leon. I wish I could."
