I own Harry Potter. (JK, Rowling.)

Harry woke up bright and early, ready to enact his plan. He dressed into his robes, although he technically didn't need them, and he changed. Lord Voldemort was now standing in the gryffindor boys' dorms, smirking to himself. He pulled on Harry's invisibility cloak and snuck through the common room, making his way to breakfast.

The teachers and students were in a panic. The most feared wizard of all time had just walked calmly into the great hall, and had sat next to Malfoy at the slytherin table, helping himself to fried egg, toast and pumpkin juice. The Dark Lord was given plenty of space, but he felt that was rude.

"What, are you calling me fat? There's a lot of table-area going to waste, you know." The slytherins, half with their wands trained on the man, slowly shuffled towards him. Harry had to transform his mouth to conceal the grin splitting his face, and anyone who didn't know better only saw a good-natured smile, which looked unnatural pasted on the most evil man ever, and frightened everyone even more.

Voldemoron felt a presence behind him. "Oh, good morning, Headmaster Dumbledore!" He spoke through a slice of buttered toast, "I trust that you've been doing well? No... Security problems in the school? I do hope, however, that the Dementors aren't the only thing keeping Sirius Black out of the school. I've heard that all it takes is one spell, one that even a third-year could get right."

Of course, Harry had researched a little overnight, and had found the spell to create that silver mist that the fridge freezers were so scared of. He had decided to master an animal Patronus, if only to found out what form it would take.

"Lord Voldemort," Professor Dumbledore stated.

"Well done, you aren't completely blind after all these years. Tell me, are the glasses just for show? Or is your vision all blurry without them, like my own worst enemy?" Dumbledore seemed mildly perturbed at Voldemort's question, but was saved from having to react. "Speaking of, where is Potter? I don't suppose he died last year, did he? I did so want to kill him myself," the master of all evil pouted. "Well, I must be going now. I dare say you'll be seeing a lot of me from this moment forth." With that, he got up and marched out of the hall, feeling the eyes of both the staff and the students on the back of his head.

Over the next few hours, Voldemort attended Harry's classes and sat in Harry's seat. Ron and Hermione seemed perfectly at ease with the situation, giving him ideas about how to murder Harry in the most painful way possible, but the teachers' attempts to reverse whatever magic was doing this had all failed; they eventually decided that Voldemort was completely crazy and had confounded Ron and Hermione, but that they wouldn't make the first move and anger him. This carried on until the DADA lesson, where Lupin decided he'd seen enough.

"Riddikulus!" The students laughed, especially the muggleborns, and Harry felt as if he was being stabbed by little needles.

"Stop!" The laughter stopped. "Do you have any idea how much that hurts?"

Professor Lupin's eyes were twinkling a little as he smiled at Lord Voldemort, who now wore a black helmet and made strange sounds whenever he breathed. "Care to explain yourself, boggart?"

"Actually, if you don't mind, I would prefer you call me... Actually I never thought of a name, did I? It's so hard to make one up on the spot like this. Let's go with... Shift." He turned to Ron and Hermione. "What do you guys think? Shift?"

"Well, I can't think of anything better, mate."

"I can't either, Shift. Congratulations on the name, by the way."

"Thanks," he grinned, then he Shifted into Ron.

"Hey! No using our faces!"

Shift turned to Ron. "What about Harry's then? He isn't here, it couldn't hurt."

Hermione sighed. "If you must."

Shift was now Harry, and he turned to discover himself at wandpoint.

"Where is Harry?" His voice was now ice-cold, and Harry shivered involuntarily.

"I assure you, Professor, Harry is fine. Although I can't find him either, he just told me to distract everyone so they wouldn't notice him gone. He said he'd be back tomorrow morning."

"I will use Riddikulus on Harry, when I see him tomorrow. Understand?"

"Y-yes Sir."

"Very well. Now, today we will be..." Lupin's voice faded as Harry thought furious. What could they possibly do? He went through a list of spells in his mind. Alohomora, Expelliarmus, Finite Incantatem, Stupefy...

This chapter was largely useless; a break chapter, if you would. I only added the plot twist at the end, as my writing style is to outline the main plot points, start writing and see what I end up with. Works fairly well, all things considered.
