3 Chapter 1: Promothane- Feel the Burn

It had been just a regular feast after a victory for Gryffindor at Quidditch. Harry Potter, as the team's captain and seeker, was developing a very sore back after all the Hufflepuffs, Ravenclaws, and Gryffindors had come up to clap his back for defeating Slytherin. Oddly enough, nobody seemed to notice that he winced after they slapped him.

Ron Weasley, as usual, had felt it necessary to re-count his personal commentary on the game from his Gryffindor Keeper position to anyone who would sit down long enough to listen. This of course was extremely annoying and he usually wound up with a short stay in the Hospital Wing because he had said the wrong thing to the wrong house.

This left the trio in this state: Ron across from Harry and Hermione Granger talking endlessly about the game, Harry trying to smile at everyone though wincing as he sat back in his chair, and Hermione focusing intently on spearing each and every pea on her plate with a fork. Though from the way her eyes kept darting to her trusty wand by her side, Harry thought she was more likely to be debating which spell she could use to shut Ron up.

"…And then Harry dived for the Snitch, but Malfoy, the slimy git, didn't realize that the Snitch was right below him, and he thought Harry was going after him. But Harry had caught the Snitch before he could do anything." Ron finished, and happily dug into his fried chicken.

"Finally!" Hermione muttered.

"What was that?" Ron said, spraying the table with chicken. "Sorry, finally what?"

Harry, though he enjoyed Hermione and Ron's fights tore his attention away to gingerly poke his back, and bit his lip from the pain.

"Finally!" Hermione said slowly, her eyes darting around, and then settling on her plate. "I've been trying to get this pea for 5 minutes, and look!" She held up the fork proudly, and Ron rolled his eyes in disgust.

"Okay…" he said doubtfully with raised eyebrows, but Harry knew that he like Hermione and didn't think that she could be making fun of him.

Harry followed Ron's example, and beat Hermione's hand to grab a large drumstick with some sticky stuff on the outside. He took a bite, and chewed thoughtfully. It didn't taste right, and his mouth was left burning as if he had bitten into a giant pepper instead. He swallowed a large gulp of pumpkin juice, but to his horror, the burn flowed to his throat and stomach. He could feel his eyes begin to water, and tried to sweep them away with his hand, but his fingers had turned numb.

"Harry? Harry! What's wrong?" Hermione said in alarm and he saw her eyes were full of fear.

Harry didn't know, his feet had also turned numb, and the feeling was crawling up his legs like a very large and creepy spider. He started swaying in his seat, and heard whispers passing along the table.

He fell to the floor, not knowing why, and saw Hermione's concerned face above him under the table. He couldn't feel anything below his neck, but was sure that something was horribly wrong, his back should've been screaming in protest.

"Ron, go get Professor Dumbledore, now!" Hermione said with authority in her best Prefect voice, but Harry could recognize the frightened quiver at the end.

He tried to tell her something, but could only move his eyes, and by Hermione's strained expression, he could guess that they were bulging.

"Hang on Harry!" Hermione repeated over and over, and held his hand as if to transfer some of her strength into him. He thought that the numbness was going away, that he was getting better.

Then the convulsions started. His body was wracked in all directions, arms and legs thrashing, but his frightened green eyes were entirely focused on Hermione's strong brown ones, as if he ever broke the gaze, the world would end. He heard her voice as if from far away, then a glorious blackness overtook him.

He awoke in a strange clear tube of some sort, but he recognized the outside as the Hospital Wing. Madame Pomfrey was standing over him with a look of pity.

"Good morning Mr. Potter." She said, and he was amazed that he could hear as clearly as if he was out of the tube.

"What happened to me, wait I can talk?" He said slowly.

"Promothane, it's a type of mild food poisoning, not fatal, but highly contagious a few hours after contraction. I'm afraid you were the victim of a very cruel prank Mr. Potter. That's why you're here in this stasis tube, with your own air supply and special food."

"Why can I talk? My whole body was numb?"

"Promothane is a very complex organism. The numbness is merely a symptom of having it in your body, it disappears after the victim passes out, and now you can move everything. Oh, yes, I also fixed up that nasty bruise on your back." She smiled at him, again with that awful look of pity.

"How long am I in here?" Harry asked faintly before she left.

"Only four days." She said, and then bustled off.

"Great, I'm stuck in a stasis tube, and Ron and Hermione get to go to Hogsmeade without me tomorrow." Harry sighed, and went to sleep, trying not to think that he had just barely beaten Hermione to the sticky drumstick.
