While Snape slept the entire night away, which truthfully was the way Harry wanted it, Harry researched in efforts to find that potion. He didn't really know why he felt the need to spend his entire night searching for it, but he did. He had already spent two hours and found nothing in the first bookshelf. Well, scratch that. He did discover that Snape was an even bigger genius at potions than Harry already thought he was. The man had scribbled all sorts of notes in the books. However, none of the books held the recipe that Harry was trying to find.

Harry sighed as he pulled yet another book from the bookshelf. However, unlike the majority of the other books, this heavy leather bound book sent a jolt of cold throughout Harry's body. He winced at the feeling and nearly cried out by how cold it was. He hadn't grabbed the book from the Dark Arts bookshelf so he couldn't understand why the book would be reacting this way to him. He quickly dropped it onto the couch before opening it. However, all of the pages appeared to be blank. He sighed and put the book back carefully in its spot before grabbing another.

Another two hours passed by with no luck still. Harry was on the very last allowed bookshelf with the very last book. His green eyes narrowed on it, and he slowly reached out to pull the book out. However, at the last moment, he stopped. His eyes caught a black book in the Dark Arts section that looked promising. He couldn't really tell why it caught his attention, but he glanced towards Snape's closed bedroom door. He didn't hear any movement so he guessed Snape was still sleeping. Drawing in a deep breath, Harry quickly yanked the black book off the shelf and walked towards the couch.

Obviously, Harry probably wouldn't likely find the potion he was looking for in the Dark Arts bookshelf, but the book had drawn his attention for some reason. He traced the intricate design etched into the cover and stared at it purely mesmerized. The design was a moon with dozens of woven wavy stitches that spiraled towards the middle of the orb, which held a small dark crystal. As he traced the design, the dark stitches slowly started to shimmer with pure silver. The black leather quickly altered its color to emerald. It was Slytherin in origin. A silver inscription burned in a circle around the moon, and Harry quickly recognized the inscription as being Parseltongue. Snakes then depressed into the leather.

"What is this?" Harry asked in disbelief. He glanced back towards Snape's closed door and then to the book. Was Snape a relation to Salazar Slytherin somehow? Harry then drew in a deep breath before picking the book up and walking towards the portrait of the Founder, who strangely enough had been staring at Harry. "Do you know what this book is?"

"Yes," the Founder replied with a sigh. "And I believe I remember Severus specifically telling you not to touch any of his books in that bookshelf, Mr. Potter."

"I know. I know, Salazar. But what is this book?"

"As if I would ever tell you, Mr. Potter," he drawled before glancing towards something in the darkness of his portrait.

"Fine then," Harry huffed. "If you won't tell me, then I'll find out myself."

"No…don't!" But the Founder was too late.

Harry opened the book. Within seconds, the book sucked him inside of it much like what had happened his second year with Tom Riddle's diary. As soon as his surroundings formed, Harry glanced around before gasping. He recognized the room instantly. He was in the Chamber of Secrets, only he knew that it was over a thousand years prior to his current year because the man currently walking towards him was none other than Salazar Slytherin himself.

"Least I don't have to deal with Voldemort this time," Harry muttered quietly. He followed the Founder further into the chamber and suppressed his urge to shudder when he saw the chamber where he rescued Ginny Weasley. However, the chamber wasn't so sinister looking as it had when he had been in it. Tall cabinets lined the entire area with thousands of sparkling potions.

"So this is where you went, Salazar? I had wondered," a soft female voice spoke behind Harry.

"Syrene, how nice of you to drop by," the Founder replied clearly being sarcastic with her. "Let me guess. You need more, and of course you decided that I was surely the only person you could go to."

"You know that's not true, Salazar. I have dozens of wizards under my thumb, but only you can make me what I want." The woman's blond curls bounced gracefully on her bare shoulders as she walked in a long silver dress towards him. "After all, we wouldn't want your wife to know about your activities down here. Do we, Salazar?" The woman then turned towards the Founder with a sly smile on her pale face. "I mean, just what would she say when she learns that her husband knowingly consorted with someone like me? I doubt she'd be as enthused as you were…blood purity and all."

"Blackmailing me, Syrene? That's rich even for you," Salazar responded with a hint of anger. "Your potion's over there on the far shelf. Take it and leave. I will not ask you again."

"Of course, Headmaster," she hissed rather softly before grabbing the black potion from where he indicated. "Tell me, Salazar. How are things with you and Godric these days? Is he still giving you a hard time about us?"

"Leave him out of this, Syrene."

"Loyalty to a Gryffindor, and here I thought you were better than that, Slytherin."

"Take your damn potion and leave, Syrene."

"Such anger in your voice," she said with a smirk. "I believe your anger was what got us into this mess in the first place." She then picked up a deep crimson colored liquid and swirled it around in the glass before pulling the stopper out. She inhaled the smell of it before laughing to herself. "So pure, Salazar," she said licking her lips. "You'll fix those dirty bloods yet, won't you, my pet? I wonder what your dear sweet Godric would say if he knew the truth about your—shall we say—true thoughts on blood purity?" She then set the crimson potion back where she got it. "Have you tried it on any of them yet to see if you've truly succeeded in getting all that nasty Muggle out of them?"

"In case you have not noticed, Syrene, I am the current headmaster of this school. I do not make a habit out of—"

"Oh, no, of course not, Salazar," she replied with a soft laugh. "Speak with one of your dirty blood Slytherins. I'm sure they'd be thrilled to see if it works."

"I think it's high time you left, Nightwalker," the Founder growled drawing his wand.

"Perhaps, but do remember that I am always here for you, Salazar." The woman then vanished into thin air, which made Harry's jaw drop. It wasn't as if she apparated or anything. She just vanished. However, soon the entire setting did, and Harry found himself on the floor of Snape's rooms gasping.

"What the hell was that?"

"Depends on what you saw I would guess, Mr. Potter," the Founder replied in his portrait. "You are rather lucky that I am not going to inform Severus of your foolish behavior this evening." The Slytherin then angrily shook his head and retreated further into his painting.

"Wait, Salazar, I have a question." Harry winced at the glare. "Did you dislike Muggleborns?"

"I did that to protect them, but as you could see, it was not as if I could inform Gryffindor about my little problem." Salazar then shook his head slowly. "My only issue with students who come from Muggle families is that their magic is considerably weaker than compared to their pureblood counterparts. The only thing I am guilty of is being a power hungry wizard, but I meant no true harm to any of my students. I only wished to protect them from her."

"What about the basilisk you left in the chamber, though? You made it so that only your heir could control it. And according to legend, you—"

"According to whose legend, Mr. Potter?" he replied scoffing harshly. "Oh, yes, I've heard the lies spouted about me throughout this castle by some of the professors. I do not blame them, though. It was the way it had to be. If the others knew that I had been with Syrene…that I knowingly allowed a vampire in midst of children, well, I would never have gotten as far as I did with my research."

"Then that purifying potion works? If a person was a half-blood, it'd purify it?"

"I never had the chance to test it. Godric and I got into a row, and I fled the castle."

"Would it still be in the chamber, though?"

"As if I'd know, Mr. Potter," Salazar responded moodily. "I've only been dead for the past thousand years. It's not as if I have a portrait in the chamber." His eyes then narrowed. "Why are you questioning me? I thought you wanted the potion that'd make Severus express himself more clearly."

"I do, but he's always wanted to be a pureblood, though. I know I'm not the only one who knows that. If your potion works, then I could pay him back for saving my life all those years."

"And you think you're not paying him back by just being here for him?" Salazar then scoffed. "How about you focus on one potion at a time, Mr. Potter? In fact, I'll even help you since you've wasted this entire night by sticking your nose in things you shouldn't. The specific potion you're looking for is in my journal. Just think 'Passion Potion,' and it should appear. As soon as it does, write the recipe down and put that book back."

"Why does Snape have your journal, though?"

"I doubt he realizes he has it, which is how I'd like it to remain. I don't need some wizard taking my recipes and claiming them as his own." Harry then nodded. "Good, well, what are you waiting for? He'll be waking up soon, and if he catches you, well, I hardly need to tell you what he'll do."

Harry did as the Founder had suggested and quickly jotted down the recipe. As soon as he finished writing the last instruction down, he yawned and shook his head. He glanced towards the closed door and sighed. Snape was still asleep. However, Harry quietly put the book back in its rightful place before walking towards the couch to reread the list of ingredients and instructions. Half of the directions look extremely complicated and made Harry wonder if he wrote it down wrong. He hoped he didn't, but he was absolutely sure he got the ingredient list right at least. He had triple checked that list and then some. Who better to experiment with potions than Snape? The man probably would find it relaxing.

Harry yawned for the tenth time and glanced at the closed door. He thought briefly about heading to his own bedroom to succumb to his exhaustion, but felt like it'd take too much energy to walk down the hallway to his bedroom. Therefore, doing as any teenager would, Harry fell asleep on the couch with the list and directions in hand.

Nearly ten minutes later, the closed bedroom door opened. A well-rested Severus Snape walked into the sitting room with a look of amusement on his face at the sight of the sleeping boy all sprawled out on his couch. He plucked the ingredient list and directions from Harry's hands before gently sliding his arms underneath the young man. He silently picked Harry up and carried him to Harry's room so that Harry would at least be comfortable as he slept. Before leaving Harry's room, though, Snape found himself carding the boy's unruly messy black hair. As soon as he realized what he was doing, he stopped and whirled out of the room. Obviously, some loss of his control on his emotions was still in effect. However, he ignored it. He had a potion to brew before his meeting with Dumbledore.
