Letters to Severus

Part 1: Chapter 1: Potions Class

Lily's POV

The four Marauders were third years at Hogwarts School of Witchcraft and Wizardry. I, Lily Evans, am also a third year. But if Remus hadn't of helped me in Charms last year… I don't even want to think about it!

Anyway, I'm about to have potions class with James, Sirius, Peter, Remus and some Slytherin students. The door to the classroom was shut and students were staring at something pinned to it. I couldn't see what they were staring at, though. I hope we can sit with who we want!

"What? We have assigned seats?" Sirius groaned.

I smacked him with my book. "Sirius Orion Black! You made my worst fear come true!" I yelled at him.

"Hey, wait! You're partnered with Alice! With Alice!" Sirius repeated. I blink. With Alice? Yay!

"Aw… I wanted to be partned with Lily…" James whined.

"Suck it up, mate." Sirius patted James on the back.

All the sudden, the door to the potions classroom opened. There stood Professor Slughorn, the prat, I mean, the Head of House for Slytherin.

"Enter." he said. "Sit in your assigned seats, please."

I looked the chart over carefully as I walk by. But the only ones that caught my eye were the people I knew.

Front row, left to right:

Peter Pettigrew-Bellatrix Lestrange

Sirius Black-Narcissa Black

James Potter-Frank Longbottem

Middle row, left to right:

Lucius Malfoy - X-X

Lily Evans-Alice Mayapple

Back row, left to right:

X-X - X-X

Severus Snape-Remus Lupin

Oh, fuck. Snape and Remus? NO! No, no, no, no, no!

"Remus!" I hiss at him. He was sitting at his assigned seat. Snape was nowhere to be seen.

"Oh. Yes Lily?" Remus grins at me. He still looks dead tired from last weeks full moon…

"Your partners with Snape!"

". . . Oh. OK. Was that all?"

"What do you mean, 'was that all?'? Its Snape! Bloody Snape!"

"Maybe James or Sirius would have something to say about that but I'm perfectly fine with it."

"Fine." I turn around to tell Sirius. "Siriu-…" I freeze. Sirius was glaring harshly at Remus. Remus rolled his eyes.

"You're 'fine with it'? What the bloody hell is wrong with you?" Sirius turned around fully. Apparently, he had been listening to the entire conversation. Not that I blame him. He likes Remus after all.

"Pads, I'm not in the mood right now. Can you just turn around and pay attention to Slughorn?" Remus asked innocently.

"Hmph." Sirius glares as class starts.

I look back at Remus. He was having trouble writing down the instructions. He struggles in Potions but if he had a partner, even Snape, he could focus more…

"Excuse me, Professor Slughorn." Snape strode into the room. Well, speak of Merlin, there he is! "I'm sorry for being late. And I notice that we have assigned seats…?"

"Ah, Snape. It's very good to see you!" Professor Slughorn says. "You're seated next to Mr. Lupin."

Sirius had fire coming out of his eyes by the time Snape passed him. Snape snorted at him, a smirk on his face.

Remus grins as Snape sits down. "Hello, Snape."

"Hm." Snape says and starts to copy down the instructions. Remus glances at Snape before doing the same. I sigh and try to keep my mind in the classroom.

"Today, we are learning how to make a…" Slughorn waited for us to fill in the blank.

"A Snivel-potion, sir? So everyone can look as ugly as Snape?" James sniggered. I choked back a giggle. Sirius didn't bother-he just burst out laughing. I looked at Remus. He was staring at Snape.

". . . No, Potter. A Czletia-potion. And 20 points from Gryffndor for making such a rude comment."

The Gryffndor's groaned and the Slytherin's cheered.

"Does anyone know what a Czletia-potion does?" Slughorn asked.

James raised his hand along with Snape, Remus and Narcissa.

"Well, now this is a surprise. Lupin!" Slughorn smirked.

"Um, i-it… turns you… invisible…:" Remus stuttered.

"And? What else does it do?" Slughorn sounded impressed. To tell you the truth, I most definitely was. He sucks at Potions! He got an O last year!

"Erm… and it allows… you to, uh…" Remus probably didn't like the attention he was being given. I noticed Snape moving his notes over so Remus could read them.

"And it allows y-you to see if… something's real, or not…" Remus finally said.

"Well done, Lupin. 15 points to Gryffndor." Slughorn began to write the ingredients for the Czletia-potion on the board.

I heard Remus whisper, "Thank you, Snape."

I heard Snape tell him, "Get to work."

"OK."

How can Remus be OK with that? That-that-that insufferable-know-it-all tone!

I sighed. Remus really didn't care. I began to jot down notes and instructions.

30 minutes later…

"Psst. Hey, Lily?" Sirius had turned around and was looking at my paper. "What did you get for the third one? I missed it."

"Why don't you ask Narcissa?" I smirked.

"Why don't you stick a pole up your arse?" he said.

"Why don't you un-stick yours?" I retort.

"Lily, watch your cauldron!" Alice warned me. She pushed Sirius' head off of our table and began to help me.

James' POV

It was shocking. Moony was being nice to Snivellus. He asked Snivellus for help with the potion and Snivellus helped him! It's bloody scary!

"Hey, Frank."

"Yeah?"

"You see Snivellus' hair, right?"

"Yeah. Greasy as shit. What about it?"

"I'm gonna turn it bright red—no!—YELLOW."

"Hufflepuff?"

"Slytherins hate Hufflepuffs! The color makes them sick!"

"You sure it's not the affects of the spell?"

"Oh, shut it! This is going to work!"

"You just keep telling yourself that…"

5 minutes later…

"Potter, detention! You do not cast spells on other students!" Slughorn yelled at me.

"… YOU. ARE. DEAD." I got down on my knees and began to beg for his forgiveness.
