"The train's still stopped. Who knows when we're gonna get to school? Can you please sing the song?"

"No."

"Come on, I want to hear it!"

"You'll hear it during dinner with the rest of the school Hannah."

"But why? You're here. I'm here. Just sing the song!"

"It's supposed to be a surprise."

"All right. Then you're not getting any of my chocolate frog cards."

The incessant whining of her friend hadn't been able to sway Mina Aino into revealing the song she would be singing with the student choir in the Great Hall that night. At last Hannah was switching to a far more effective tactic: threats.

"Well, I guess a few lines wouldn't hurt."

"Uh-uh. The whole song or no cards."

"Fine." After a disparaging shake of her head at a stubbornness even greater than her own, Mina began to sing.

Double, double, toil and trouble,

Fire burn and cauldron bubble,

Double, double, toil and trouble,

Something wicked this way comes

Eye of newt and toe of frog, Wool of bat and tongue of dog, Adder's fork and blind-worm's sting, Lizard's leg and howlet's wing. Double, double, toil and trouble Fire burn and cauldron bubble Double, double, toil and trouble Fire burn and cauldron... Bubble

Something wicked this way… comes..

Mina thought that the growing uneasiness with which Hannah was looking at her was do to the lyrics and the creepiness of the melody (purebloods like Hannah rarely heard of Shakespeare) but even as she was singing Mina felt the chill in the air. The lights in the train carriage dimmed and an unexplainable dread suddenly overcame Mina, as if the air itself was afraid. Her voice died at the words something wicked this way comes, as though song itself were drained from the room.

The door to the compartment opened and a dark figure entered the room. It wore a black cloak that concealed its face and billowed in every direction like rippling water. The only parts of its body that were visible were its hands-long, dark, rotted pieces of flesh. It floated above the ground so that it moved silently.

In fact the only sound it made was its breath. A continuous whine like a creepy nighttime wind. It was sucking in everything, the light, the warmth, the joy, the song, and leaving nothing but despair behind for Mina and Hannah.

The creature turned its head towards Mina, who was shivering and wondering if she would ever be warm again. The sound of wind grew louder as it strengthened its breath. Mina closed her eyes so as not to look into the dark space that concealed its face…

And found herself staring into another frightening face.

The evil woman was full of anger and hatred, but it melted into surprise. She looked down at the great sword of glowing crystal thrust through her belly, and died silently upon that sword.

The battle was over. Mina collapsed, exhausted, and looked around at the carnage of the battlefield, hoping to find her comrades still standing. The bodies were so prevalent that in no direction could she see the ground.

But behind her was someone in a blue and white outfit lying on top of fallen foes and looking forward with unseeing eyes. Not far to her right the one in the green and white outfit was impaled on a great staff.

Mina threw her head back, and with all her remaining strength she screamed.

"Mina!"

Mina opened her eyes. She had fallen off her seat onto the floor, Hannah and a man she did not know looking down at her with concern. And she was still screaming.

With the slow realization that she was back on the once again moving Hogwarts Express Mina's screams ceased and were replaced by heavy breathing. The man and Hannah helped her to her seat again. She was still freezing and the side of her head hurt and was possibly bruised, but she was beginning to cry for a completely different reason. She had a terrible sense of loss.

Only she had no idea what it was she had lost.

The man extended his hand, inside of which were several pieces of chocolate. "Eat this. Chocolate is the best treatment after an encounter with a dementor."

Mina looked at the chocolate skeptically. "A dementor?"

"One of the creatures that guard Azkaban prison."

Mina considered for a second. The man seemed to know what he was talking about, but she couldn't see why chocolate would help her. 'Still,' she reasoned, 'chocolate can't hurt.'

She took the chocolate and after a few bites felt warmth returning to her body. She took her first good look at the man who gave it to her. He looked like a frail person and his clothes could only be described as shabby.

"Thanks Mr.…"

"Lupin. Professor Lupin. You finish that now. I was on my way to talk to the conductor when your friend came out and told me you had fainted. If you're all right I'd best find him now."

Mina nodded and continued to eat the chocolate, feeling stronger with every bite.

Hannah sat down after Professor Lupin had left. "Are you sure you're all right?"

"I think I'll be shaking for a while."

"Same here. It got so cold. And I couldn't help but think of things I don't like to remember."

Mina seized that point, desperate for an explanation for what she had seen when she'd passed out. "Like what?"

"Oh, the time I crashed my broom into a tree when I was seven. Things like that."

"Oh." Mina said, disappointed. "Me too. Only you didn't faint." Nor, it seemed, did she have a vision of any sort, only a recollection.

"Professor Lupin said you weren't the only one."

"Did he say who else fainted?"

"No."

'Shoot.' Mina thought. 'If I'm going to find out what it is I saw I'm going to need to find whoever else fainted.'

"Mina?"

"Yes?"

"Don't start singing again."

They laughed./

Outside the train Mina said goodbye to Hannah and went towards where Professor Flitwick was gathering the choir members.

"Miss Aino," he said. "Professor McGonagall wants to see you in her office."

"But I just got off the train. What could I have done?" she asked defensively.

"I don't think you're in trouble. Just go."

"But what about the choir?"

"We'll get along fine without you."

Disappointed and a little insulted, Mina set off towards the office of Minerva McGonagall. She was quite surprised to see Harry Potter and Hermione Granger there.

"Oh, hi Harry. Hi Hermione." she said, unable to stop her cheeks from turning red. Being in Hufflepuff, she didn't see either of them very much even though they were all third years, but by killing Slytherin's monster at the end of the previous year Harry had saved all the Muggle-borns in the school, including Mina.

As soon as she arrived the door to Professor McGonagall's office opened. The head of Gryffindor House was there along with the school nurse, Madam Pomfrey, who was not pleased to see them.

"Potter. I suppose you've gotten yourself into something dangerous again."

"It was a dementor, Poppy." Professor McGonagall said.

"Yes. They both look pale and clammy." the nurse said as she observed Harry and Mina.

"Is there anything you can do for them?" McGonagall asked.

"The only thing I recommend is chocolate."

"I've already had." Harry said quickly. "Professor Lupin gave me on the train."

"Me too." Mina added.

"Did he? So we've finally gotten a Defense Against the Dark Arts teacher who knows his remedies? Well then there's nothing left for me to do." She began to leave but stopped in the doorway. "Dementors!" she said loudly to McGonagall, "in a school! They won't be the last who faint Minerva. Mark my words."

"Well," McGonagall said. "Potter, Aino, you can head down to the feast. Miss Granger, I'd like you to stay."

And so it was that Mina found herself walking alone with Harry Potter. She tried to open her lips, but nothing came out. They had more in common than merely fainting on the train. Neither of them new that they could do magic until they heard of Hogwarts and both of them had lost at least one parent violently years earlier, in Mina's case her father. But she was still too self-conscious to speak with the Boy Who Lived.

Fortunately Harry was more than willing to start a conversation. "So you fainted too?" She nodded. "Any idea why it was only us two?"

"Um, no….um, did you…er...see anything when the dementor…you know?"

"No. But I heard someone screaming."

"Maybe we were in some dementor trance thing and you heard me screaming."

"Maybe."

"So what do you think dementors are doing here when they should be by Azkaban?"

"Looking for Sirius Black."

Mina stopped. "The guy who killed thirteen people with one curse."

"Yes."

"You-Know-Who's right-hand man."

"Yes."

"The only person to ever break out of Azkaban.

"Yes."

"Here."

"Yes."

"The day keeps on getting better and better. Why here though? Is he after you or something?"

It was not a serious question, but Harry did not respond at all.

"He is, isn't he."

"Yes."

"You don't seem too worried."

"Well, it's not like Black can be any worse than Voldemort." Mina's eyebrows went up in surprise, but not fear, at the mention of the Dark Lord's name. As a muggle-born she had not been raised to fear the name. She'd just gotten into the habit of not saying it because nobody else did. Sirius Black was more frightening in her mind because he was a threat now, rather than the old threat of Voldemort.

"Oh." she said when they reached the Great Hall. "We missed the sorting. I really wanted to hear the hat's song."

"Well you heard it for the past two years. And we'll hear it again next year."

Mina looked at Harry in surprise. "Where were you last year? The hat makes a new song every year!"

"Really?" It was Harry's turn to look surprised.

She nodded. "And if we missed the sorting we missed the choir. I practiced so hard for that song, all for nothing."

"Well I didn't hear it."

Mina smiled. "The last time I sang it for someone a dementor attacked me. I'm going to just eat and sleep and forget about it."

They headed for their tables, Gryffindor and Hufflepuff, and sat down to eat. But despite her declaration of intention to forget, Mina stopped as she held a piece of meat to her mouth, still looking worried. She had a bad feeling in the pit of her stomach.
