Chapter 17: Advance Potion Making
Severus felt like he had to wait forever for the boy to return. After he had vanished the water on the floor, he turned his wand on himself and vanished the blood and water from his on robes.
Once he was finished, he looked to the doorway again and finally saw Harry standing there, with book bag in hand.
"I didn't mean for that to happen," Harry Potter blurted out. "I didn't know what the spell was suppose to do."
"Who would have thought that the Chosen One would have known such Dark Magic?" Severus spat, ignoring Harry's statement all together. "I'll ask again. Who taught you that spell?"
"A…a library book," Harry stuttered.
"Give me your book bag," Severus command, as he held out a hand to receive it. Harry silently handed it over, and watched as Severus extracted each book, one by one, and examine them.
As Severus pulled out the "Advanced Potion Making" textbook, he began to look it over carefully. He flipped through the pages slowly and then flipped back to the inside cover.
"Is this your copy of Advanced Potion Making, Potter?" Severus scowled at the boy.
"Yes."
"Are you positive Potter?" Severus sneered. He noticed that Harry was breathing harder than normal, and suspected that it wasn't from running all the way from the common room.
"Yes."
"You purchased this textbook from Flourish and Blotts?"
"Yes," the boy said more firmly.
"Then tell me why it has the name Roonil Wazlib' written in its' inside cover?" Severus sneered. He now knew that the boy was surely lying to him.
"It's my nickname," Harry said quickly.
"Do you what to know what I think, Potter?" Severus sneered more. "I think that you are a liar…and a cheat. You will serve detention with me every Saturday until the end of term. Is that clear?"
"But sir, I have Quidditch," Harry protested.
"Then they'll just have to lose without you," Severus smirked as he walked towards the door. "Ten o'clock, in my office."

After Severus had left the boys' lavatory, he headed straight for the hospital wing, where he found Katherine sitting at Draco bedside. The boy seemed to be asleep as Severus walked up to stand beside Katherine's sitting form.
"So," Katherine said, looking up at him. "What happened?"
"I believe that Potter has my old potions textbook," Severus said quietly, as he summoned a chair so he could sit beside the bed.
"That's impossible Sev," Katherine shook her head. "You said you destroyed that book when we graduated."
"I said I was going to," Severus said a little louder; his anger starting to grow. "I never got the chance remember. Potter and Black stole my book bag with one week left of school and it was the only book I never got back."
"So where is the book now?" Katherine rose a questionable eyebrow in Severus' direction.
"I don't know," Severus muttered, as he fell back in his chair and crossed his arms. "Obviously the boy has hidden it, because he had someone else's potion book in his bag."
"Well," Katherine paused in thought. "When his class comes around again on Friday, I'll pop into the classroom and act like I am going to get something from my desk, when in reality I'll check in on his book."
"Thank you," Severus sighed. "And if he does have the book, he's going to get more that just Saturday detentions."

In the Gryffindor Common Room…
"Harry, you have to get rid of that book," Hermione snapped at him. "Look what it has done."
"You know I don't like Malfoy, any more than you do Harry," Ron said. "But Hermione right. You have to get rid of it." Harry was sitting on the floor of the common room; his back leaning up against the couch, as he flipped through the Prince's book. Hermione was nervously pacing the room, and Ron and Ginny were sitting on the couch behind him.
"It has to go," Hermione reprimanded him again. "It's obvious enough that this Prince was into Dark Magic." But Harry wasn't paying attention anymore. He had stopped flipping through the book and was stuck on a page with what looked like two more nicknames. One was in a very neat handwriting, definitely not the Prince's handwriting. And above it, in the same handwriting, looked to be another spell.
"Volpe," Harry whispered.
"What?" Hermione stopped pacing to stare at him.
"Volpe," Harry said a little louder. "It looks like someone else wrote in this book too." He pointed to the name, so that Ron and Ginny could see it.
"Harry forget the book…" Hermione started, but Harry cut her short.
"Wonder who it is?" Harry mused. "And look in the Prince's handwriting; he wrote 'Cervae.' Is that a spell or another nickname for him or someone else?"
"She…" Hermione stated, as she crossed her arms.
"He, she. What does it matter 'Mione?'" Ron said as he looked at the book for a second, before his sister plucked it out of Harry's hands.
"Hermione right Harry," Ginny said softly. "It's time to get rid of it. I think the Room of Requirement would be the best place for it. No one should find it there."

As Friday morning rolled around, Katherine did as she promised and popped into the potion's classroom and check in on Harry's book. But to her surprise, the boy was sharing a book with the Weasley boy, and the potion was turning into a disaster.
Katherine was furious to say the least, a began pondering on where he could have hidden the book. She was making her way as quickly as she could to Severus' office, when she suddenly stopped.
'Of course,' Katherine thought to herself. 'The Room of Requirement.' Katherine turned and made her way to the seventh floor corridor.
She came to a halt in front of the tapestry that featured Barnabas the Barmy trying to teach trolls ballet and began to pace back and forth three times in front of it.
'I want to find the Half-Blood Prince's Potion book, I want to find the Half-Blood Prince's Potion book, I want to find the Half-Blood Prince's Potion book,' she thought as she paced. After the third time repeating her thought, a door appeared, allowing her entrance to the room.
Katherine opened the door to find the room empty, except for one lone book, laying in the center of the room. She walked quickly over to it, and snatched it up from the floor.
The book was tattered and worn, and Katherine flipped it open to the inside cover to reveal the narrow handwriting. This book is the propriety of the Half-Blood Prince.
"Good try Potter," Katherine muttered to herself. "But not good enough."

Severus was sitting at his desk, grading papers, when a soft knock came.
"Enter," Severus said, as he continued to grade the fifth year papers. He heard the door open and the staccato clicks of heeled shoes coming towards him. He was about to look up, when suddenly, a book landed hard on the top of his desk.
"Look what I found," Katherine smirked, as Severus looked up at her with narrowed eyes.
"Potter had it didn't he?" Severus sneered, as he looked straight into Katherine's eyes, waiting for the answer that he wanted so much to hear.
"It wasn't on him, unfortunately," Katherine grimaced as she moved around the desk and perched herself on the edge nearest to Severus' sitting form. "I found it in the Room of Requirement."
Katherine pushed her onto the desk a little more, so that she was fully sitting on it. Her black pencil skirt rode up a bit just above the knees, revealing the pale, silky yet scarred legs underneath. She crossed her legs and settled her lower foot on the handle of one of the desk's drawers.
"He didn't hide it very well though," Katherine continued. "I only had to try it once, and found the book right away. So now we can get rid of this for good. Right Sev?
But Severus didn't respond, as he eyes were fixed on Katherine's legs that were dangling off the edge of his desk. His eyes wandered up farther to the edge of the skirt and the thought hit him of what lied beneath.
"Severus," Katherine said, "Are you okay with this idea?"
"Of course I am," Severus said with a frown. "I mean, we're just using it as a stress release and nothing more. Right?"
"Right," Katherine nodded her head in agreement. "No strings attached. We're just using sex to relieve our stress and nothing more. Sound good Severus?"
"Severus?"
"Sev? Are you with me?" Severus flinched and quickly looked up to meet Katherine's bewildered expression looking back at him. "What's the matter with you lately?"
"Nothing," Severus snarled, as he pushed himself away from his desk. "Give me the blasted book." He held out his hand and Katherine handed the Potions book to him.
Severus snatched it out of her hand and proceeded to walk to the middle of his office. He threw the book to the stone floor and the bang it emitted echoed throughout the room.
"Incendio!" Severus growled, as he set the book a blaze. Katherine sat in silence as she observed Severus actions. Her brow furrowed in thought as she contemplated his shortness with her, but quickly shrugged it off.
"Well," Katherine said, as she slid off the desk. "Now that that is done, I'm going to stop into the infirmary and see how Draco is fairing." She waited for a response as she came to stand by Severus' side, but never received one. He only glared angrily at the book, as he continued to watch it burn away to nothing.
"Okay," Katherine said with annoyance. "I guess I'll talk to you later then."
Severus listened to her footfalls as they left the room and as she shut the door behind her. Quickly Severus spun and grabbed an empty vial from his desk. He threw it as hard as he could, into the opposite wall, and watched as the flask shattered into a million glittering pieces.
"As if those bloody dreams are bad enough, now I'm have flashbacks during the day," Severus yelled at himself. He cursed at the fact that he want to run a hand up Katherine's well-toned pale leg and slide it underneath her skirt. Merlin, those legs looked like they had hardly changed in the past fifteen years. Just as lean, yet muscular as they always had been…
"Stop it." Severus yelled at himself again. He threw himself into his chair and glanced up at the spot where Katherine previously occupied. His mind wandered back again to the agreement that they had made between them so many years ago and he felt himself grow stiff at the thought of Katherine's body wriggling beneath his.
"Great," Severus sighed, as he pinched the bridge of his nose with his thumb and index finger. He rose from his chair and proceeded down to his private chambers, in desperate need of another cold shower.
