It was this one bathroom, on this one floor, in this one castle that happened to radiate the strongest scent of rotten basilisk. It was this bathroom that elevated the severity of the basilisk fever exponentially with every second spent in the bathroom, second only to the Chamber where the basilisk lay. Due to the stench, girls usually walked in and walked right out, but Matilda was hurrying to her next class, and this bathroom happened to be on the way. It smelled pretty bad--Matilda felt a little light-headed even stepping in there. Trying to pay it no mind, she stepped into a stall, locking it and doing her business. Matilda had a bit of a stomachache and her bowels weren't participating, so it took a while to get them to flow. Regret filled her as the smell wafted through her nostrils, making her feel nauseous. Trying to finish up her business quickly, Matilda pushed the rest of the painful cylinders out of her anus. God, it hurt. So badly.
The toilet was flushed and Matilda stood, stumbling a little. She felt rather dizzy, and leaned against the side of the stall, breathing in and out. In and out. In and out. She took a deep breath and slowly reached down to hike up her skirt. With every movement, her world spun and spun, leaving Matilda feeling even more nauseous than she had just being in the room. Once her skirt was up, she whirled around, doubled over and vomited. She vomited like she never had before. It was somehow even more violent than it normally was when she got a stomach bug, and it just came out with no mercy. After it was all over, she was left gasping, and she felt rather empty-headed. It was as if her head was as light as a feather and the rest of her body was solid iron.
Slowly, she crawled on her hands and knees, opening the stall and crawling out into the main bathroom. No one else was there, not even Myrtle. Matilda blinked rapidly, but her vision didn't clear. It was blurring, fading, and everything was spinning. Her arms turned to mush, and she fell forward, laid out on the bathroom floor like a limp rag. Then, everything was gone.
