Hello! This is my first Harry Potter fanfic. It's fun :P

Oh, and I own nothing, which gives me the freedom to f*** up the characters without any concern, lol. My respects to the owners, though; I Adore Ya!

Chase wasn't feeling his best this morning, and House knew that. It was the third time that the young doctor suggested a disease that again didn't make any sense. "Could be…"

House tolerated enough. His palms rid the back of the chair he stood behind and he lifted his bright blue eyes. Cameron and Foreman who were sitting nearby widened their eyes at House's upcoming fury, which always included Chase. They glanced towards the blond doctor before House could scold him.

But their elder's anger just came out as a subtle exhalation, and he said, "Chase," he sighed. "Go get me a coffee and don't come back till you've raked your pretty blond out of your nonsense of this morning."

Enraged, Chase tread the corridor that lead to the coffee machine. Nurses and doctors cleared out of his way, recognizing and knowing how unpleasant House's affect on his team member could be.

Chase reached the coffee machine and pierced his hand through his pocket. Coins splattered the ground noisily, when he took one out and slid into the slot of the machine. He was still muttering while he pressed the buttons with rage, barely caring whether he was pushing the right ones or not. He pressed enough buttons. Suddenly, just when he was about to stand upright again and wait for the machine to pour his order, he noticed a weird smudge on one of the buttons he'd pushed. Carefully, he started to probe the red stain, when suddenly a face with long drooping skin-colored ears and a long noise grinned at him and cried cheerfully in a squeaky voice, "Harry!"

Chase yelled and jumped back. He looked around at the startled, staring people around him, before he looked back at the smudge. The face was gone, but the smudge wasn't. He wondered whether House drugged him, but he hadn't eaten or drunk anything since he came this morning.

Slowly, he reached for the smudge again, and this time, when he stroked it, he found himself in a completely different place. It was indeed peculiar. He was standing in what looked like a classroom with students still shuffling in their seats, still waiting for the lesson to start. The student stared at him when he clearly appeared out of thin air. Chase wrinkled an eyebrow, annoyed that that didn't bother the student at all. In the back corner, he saw a boy with ruffled black hair, and obvious green eyes talking to something hidden under his desk.

"Where's Professor Snape?" one of the students asked Chase, but Chase didn't answer. He was making his way with great interest towards the boy with black hair and – a scar, Chase noticed. He could see the flapping ears from afar, and that's why he went to the boy's desk to investigate. He found the same face that appeared to him before he came here talking to the boy and the boy was trying to make him go away.

"Harry Potter," the strange little man squeaked. "Dobby is so glad to see that Harry is not hurt."

"I'm okay, Dobby, now, please, leave," said the boy called Harry Potter. "Snape is –"

At that moment, a bushy brown-haired girl sitting next to him elbowed him, causing Harry to look up and stare at Chase in first, fear, then astonishment, then, Chase didn't know why, relief. A boy sitting next to the girl was grinning with what Chase described as the joy of an elephant and looking up at the doctor.

"Are you a replacement? Is Snape gone?"

"Of course, not," said the girl in a huff. She clearly disliked that red-haired boy. She glanced up at Chase. "Don't get your hopes up. Snape never leaves. Unless…"

"He's finally taken the Defense Against the Dark Arts positions."

The girl wriggled uncomfortably in her place, still eyeing Chase. "I doubt that," she self-importantly said, but nervously, as well. Chase narrowed his eyes and turned back to the boy called Harry Potter. The strange man had gone now and the boy had his elbows on his desk, looking up at him with as much curiosity as the rest of the now silenced students.

"Excuse me," Chase said edgily. "What is this place?"

The annoying brown-haired girl interrupted again, arcing her eyebrow. "You mean, this classroom?"

"No… yes…" Chase didn't know what to think. He looked around. "Why are you all dressed in robes?"

A hard clank sounded from the front of the classroom where Chase had appeared, and thinking it was House's cane, he slid quickly under the desks of the Harry boy and the annoying girl. He glanced at him to each other for a second, before they turned back to their front with what, Chase couldn't believe it, the same look him, Cameron and Foreman gave House, at least, when they first started working for him.

The lesson started. The weird, obscured professor who was giving them the lesson gave them some strange instructions, accompanied by ingredients of some of the most disgusting things Chase, the doctor, had heard of. Cat bile, cockroach whiskers, guts of salamander, and bat eyes for God's sakes. Chase had taken a peek at the board where that was written and marveled the speed of the professor's writing. He didn't get a chance to glance at the teacher himself, though.

"Are you alright?" asked the girl, whose desk he was hiding under.

"Fine," Chase said through his wince.

"Ugh, I still got it wrong."

"Harry," said the girl, turning to the boy with a sigh. "It's only one teaspoon of ant feces, not two."

Chase couldn't tolerate it and made a retching sound.

"Shhhh," said the three children at once.

Yet, from the looks on their faces, Chase could tell that he wasn't saved. The three pair of green, blue and brown eyes watched carefully the front of the classroom, till the clanking boots, which the teenagers' pupils were following, neared their desk.
