A/N: Hey guys! Here's chapter three :D

Disclaimer: Still don't own Harry Potter…*sigh*

A few hours after the fiasco in the common room, Lily took her duty of Head Girl and showed Hermione around Hogwarts. Hermione looked at all the familiar land marks that she had passed hundreds of times in her six years of schooling, never truly understanding how precious each one was to her until she had gone through the war and saw the all collapse. The common room to start held the most memories for her, both good and bad. She remembered playing wizard chess with Ron, who had purposefully let her win the first time they played each other; the times when she, Ron, and Harry would just sit by the fireplace late into the night, talking about the latest Quidditch game or plans for the next big adventure-just semi-normal things that had become tradition in Hermione's life. Hell, she even felt relief when they pasted Moaning Myrtle's bathroom and saw that it was still in one piece. In here reverie, she had forgotten that Lily was speaking until now.
"...and here is the library. It's huge, and a place you'll want to know where it is for big assignments given by the professors, especially McGonagal. She's very strict when it comes to homework length. Even a centimeter off from the required length will have her deduct points, no matter how good of a report you write," Lily explained, and Hermione nodded at what she already knew.
The two girls entered the library, and Hermione felt a smile come onto her face. "I love it here already."
Lily brightened up. "Thank Merlin, I was starting to wonder if you were one of those preppy girls who only care about their make up..." Lily admitted, and Hermione laughed.
"No, definitely not. I could care less, actually."
"That makes two of us."
They walked further into the room, and Lily stiffened. Confused, Hermione followed Lily's gaze to a table. A boy was hunched over a potion's book and a piece of parchment, his greasy black hair touching the table along with his long nose. His charcoal black eyes darted toward Lily, and he immediately got up. The look of sorrow and regret in Severus Snape's eyes made Hermione feel bad for her potions professor...then she remembered all the times he'd called her an insufferable know-it-all, and some of that feeling went away.
"Lily..." Severus began, but Lily held a hand up.
"Save it, Snape."
"But-"
"I said, save it!"
Severus shrunk back from her a little and looked at Hermione for a moment. Then he gathered his things and stalked off from the table, leaving behind his potions book. Hermione grabbed the book and opened the front cover. Something was inscribed in it, and she tilted her head, curious. Then her eyes widened at the words.
'This book is property of the Half-Blood Prince.'
"Be right back, Lily. He forgot his potions book," Hermione said, then went after Severus. He was right down the hall, rummaging through a bag for something.
"Hey!"
Severus turned and saw Hermione running toward him with a book in hand. She handed it to him, and he took it.
"You left it on the table," she explained. Severus looked at Hermione for one more minute, then walked away without a word.
A bit confused and annoyed that he didn't say thank you, Hermione returned to the library to take the rest of the tour with Lily.

It was odd to run into your potions professor twenty years younger, especially when last you saw him, he died right in front of your eyes. That was on Hermione's mind the rest of the week as she looked at her schedule, which was almost identical to Lily's.
"The only difference," Lily explained. "is that you have Defense Against the Dark Arts and Herbology with James and Sirius. Other than that, the schedule is exactly the same. Reckon Dumbledore did that on purpose, placing you with either the Head Boy or Girl?"
"Probably. Dumbledore is a very odd and mysterious man, from what I know of him." Hermione replied as they sat in the Great Hall for lunch that day.
"Thought your family was friends with his," Lily said.
"I never really paid much attention to his visits," Hermione lied. That's another strange thing she realized. Lying was becoming easy.
Lily asked no more questions, and continued eating her mashed potatoes. A loud noise came from the hall, and Lily and Hermione looked at each other, knowing who it was already. Sure enough, Sirius and James had set off ten Zonko's products at once and ran into the Great Hall, laughing like idiots. In the background, three Slytherins were screaming as a firework chased them.
The two Marauders received stares from the girls, and their laughter ceased at once.
"What the hell are you doing?!" Lily shouted at them. "Especially you James, you're the Head Boy for Merlin's sake! You need to set an example for the first years, a GOOD example!"
James looked down at his feet while he was scolded. Everyone else in the Great Hall, including Sirius, snickered at a very sullen looking James. Hermione turned her attention toward Sirius.
"You too, Sirius! You're a seventh year student, you can't just waltz around causing havoc all over Hogwarts! I'm ashamed of both of you." she scolded, and Lily nodded in agreement. Just then, the three Slytherin boys stormed to their table, glaring at the two Marauders, while the rest of the Marauders came into the Great Hall. Remus and Peter were laughing so hard, their faces turned bright red and tears streamed down their cheeks.
"Prongs, Padfoot, that was brilliant!" Remus said after he got his laughter under control. "Absolutely brilliant!"
Peter nodded his head in agreement. "Why did you start it without us?"
"Because we're impatient, Wormtail," Sirius replied, popping some bread into his mouth.
Hermione ignored them and went back to eating. 'Boys...'
Then there were footsteps, and Hermione looked up. The Great Hall had gone silent and stared. Standing before her, Lily, and the Marauders were the three Slytherin's, clearly not amused. She noticed Severus Snape to the left of the head Slytherin boy, and a boy who looked remarkably like Sirius to the right. In the front was a third Slytherin, his long blonde hair reaching just past his shoulders. He had piercing blue eyes that bore down on the six Gryffindors, and he held an air of superiority around him. Hermione gulped. She recognized him, the coward that could only be known as...
"Hello Potter, Black. You have some explaining to do," Lucias Malfoy sneered with a wicked grin.
