A/N: These notes are the day after the full moon, all the way through 1st year. The last one will be the day after the first full moon 2nd year, when they confront Remus. Or after. Or when they decide to. We'll see.

September 6, 1971- Transfiguration

Hey, James, where's Remus? (SB)

Don't know. Maybe Peter's seen him? (JP)

Who're we talking about? (PP)

Remus. (SB)

Oh. (PP)

Well? (JP)

Why do we have to initial? We can tell each other's handwriting apart.

Good point. You started it.

Where's Remus?

Oh, right. Pete, you seen him?

He said something about not feeling well last night.

Then maybe he's in the Hospital Wing.

That makes sense.

Why do you think I said it?

McGonagall's giving us odd looks.

Fine, let's just agree to check the Hospital Wing at lunch, and leave it there.

Sure.

OK.

October 5, 1971

I wonder how Remus' mother is.

She must be very ill, if he's allowed to leave Hogwarts to visit him.

Maybe she's been bitten by a nargle.

What?

Sirius... How are we even supposed to respond to that?

Hold on.

Ow. Why'd you hit me?

I was trying to knock the stupid out of you.

Seriously, Nargles?

Where did you even get that?

A well-respected periodical.

Which one?

The Quibbler

Did Remus tell you that it was a "well-respected periodical"?

Yes, why?

He's a better sense of humor than I thought.

I didn't know you thought.

Shut-up.

I didn't say anything. What's Snivelly up to?

He's brewing a Potion.

Clearly.

Sirius is right. He looks up to no good.

Then maybe we should be up to no good ourselves.

November 3, 1971

Is it just me, or is Remus sick more often then he's here?

It isn't always him that's sick. But you're right. It seems like he's been out at least two days every month.

Yeah. I wonder about that.

Maybe he's just a really sick person. When I was younger, I used to get really bad ear infections all the time.

He's got a point.

I suppose. He hasn't mentioned his mother's illness at all since he got back.

So?

Maybe Pete's right, and he doesn't want us thinking he's really sick all the time.

I hope it isn't serious.

Why would it be me?

I didn't say anything about you.

You spelled 'serious' wrong.

Oh.

You don't think Remus is really sick, do you?

Who knows?

Remus. Probably Pomfrey. Maybe McGonagall.

I didn't mean that literally.

I know. But those are the people we have to confront to find out.

Maybe Remus isn't really sick.

When have we ever been wrong?

Never mind, then.

We'll wait, and see if he gets sick again.

Okay.

I like that idea.

December 3, 1971

There's something wrong.

Definitely.

Shouldn't we just ask him?

No.

Of course not.

Okay.

January 1, 1972

Dear Remus,

It's too bad you couldn't spend Christmas and New Year's with us. We had a blast, seeing as how James got to stay.

Thanks for sending the Honeyduke's chocolate. I've never had it before, because my parents say it rots your teeth and makes you hyper. And they say Muggles eat it.

How's your mom? I hope she's doing better.

See you when term starts again.

Sincerely,

Sirius Black

January 31, 1972

He's out again.

Yes.

What are we going to do?

No idea.

Got anything, Pete?

We could ask...?

Got anything useful, Pete?

Just that.

Great.

Useful.

Maybe we could do research. That's what he would do, if it was one of us.

I think he would ask, if it was one of us.

I don't think we'd tell, if it was one of us.

Sirius is right.

I'd tell.

That's you. Where should we start?

We should find out where the Library is.

Who're we going to ask? The only one of us who's been there is Remus, and we can't ask him.

I've been there.

You've a horrible sense of direction.

What about the red-head, Evans? She seems to be the type to know where the library is.

I guess.

She doesn't seem to like you guys, though. Remus is the only one of us she talks to.

Oh, well.

We'll ask her anyway.

March 1, 1972

Maybe we should just ask him.

No.

We'll figure it out ourselves.

But we've got to the library three times. We haven't found anything.

It isn't our fault the library stocks so many excellent guides to hexing and jinxing.

Sirius is right. The Library shouldn't be so distracting.

What are we even looking for?

Clues.

Illnesses that have once a month treatments.

Maybe it would help if we kept track of when he's out.

Already done.

Have you marked down today yet?

Yes.

Fine, we'll keep looking. I still say we should just ask.

You're entitled to your opinions.

No matter how wrong they are.

March 30, 1972

I can't believe we've been banned from the Library.

We haven't. Just Sirius.

How was I supposed to know you dodge that tripping jinx? I thought you were all for testing out those things.

On other people!

Well, I still say it's your fault that book shelf fell over.

And the other 6?

Cause and effect.

It was kinda cool, like watching those Muggle domino things.

Sure, Pete.

You guys should just go in and take out a bunch of books. We can look at them in the dorms.

What if Remus finds them?

We can keep them in Pete's trunk. He'd never go in there.

I wish we could all just go in there and look together. No offense, Pete, but Sirius is a more fun researcher.

It's okay.

I wish I could help, too.

Wait a sec! We could use my cloak!

I'm sure we'll find plenty of information outside.

Not that, stupid. I mean my invisibility cloak. You could hide under it, so we could all go in together.

I didn't know you had an invisibility cloak. Lucky bastard.

What's an invisibility cloak?

A breed of duck.

It's a cloak that makes the wearer invisible.

Groovy.

That's my word.

Sorry.

What do you guys think of my plan?

It sounds good.

Let's do it.

April 29, 1972

I still haven't found anything, and I read all the way through History of Magic.

Me, too. I wonder if Peter's got anything.

No. Maybe we should just ask him. We've been at this for months, and we still don't have anything.

We're the Marauders. We don't give up.

Marauders?

Filtch called me one last night. I looked it up in Remus' dictionary. It seems to fit.

Cool.

I like it. We can run it by Remus when he gets back from... What's his excuse this time?

I wasn't listening.

I forgot.

Well, whatever it was.

We should really keep looking in to that.

We will. In fact, let's go back to the Library tonight. We can get new books. These aren't helping.

Okay.

Tonight it is.

May 29, 1972

Maybe Remus doesn't want us to know what's wrong.

Then he's hiding something.

So?

The Marauders are brothers. We don't hide anything.

Sirius hides stuff from his brother.

That's different.

Why?

He has to.

Maybe Remus has to.

Shut up and go back t work, Pettigrew.

Fine.

September 23, 1972

Remus is a werewolf.

What?

I agree.

What?

All of his absences were on full moons, and the days after.

What?

And did you see how he reacted to Zimmerman's Werewolf Lesson?

What?

Yeah. And why else would he go home for the last three days at your place, only to show up right on time for, and all the way through the trip to Pete's?

Maybe he just thought James' mom babied us all too much.

What!?

Well...

My mother does NOT baby!

She tucked us all in, mate.

So?

I haven't been tucked in since I was 8.

I've never been tucked in.

I though we were talking about Remus.

We aren't technically talking.

Shut up.

You're right, though. What do we do about Remus?

Why do we have to do anything?

Because he's a werewolf.

No he isn't.

Yes he is.

Since when?

I dunno.

Maybe we should ask him. I mean, if he weren't...

It wouldn't make a difference. Marauders are brothers 'til the end. No matter what.

We should still ask him about it.

When?

Tonight, right before he leaves for wherever he spends the moon.

Agreed.

Okay.

Done. That's the plan.

September 26, 1972

You guys aren't mad at me?

What are you talking about?

After what you found out, you're still talking to me?

You're our friend.

Nothing wrong with you.

You just have a furry little problem.

If you keep talking like that, someone will find out.

I didn't know Remus had a bunny.

Shut up, Peter.

Really, just stop talking.

Sirius, won't your family be angry if they find out you're friends with a half-human?
We're all half-human. It's just that some people are one half, and others are two halves.

You're insane.

Am not. That's what I'll tell my parents if they find out.

I guess.

Remus is still human. He's just a bit different.

And we love him anyway.

We're burning this note.

Done.

A/N: There you go. The longest update I've ever written. 13 pages. Not quite the relaxed Sirius I thought I'd write, but I decided I wanted do explain the Werewolf Discovery right now, so here's this chapter. As I was writing, I was wondering what was going on outside Sirius' note and letters, so I may do a companion ficlet or two. Nothing is certain, though. A new semester starts tomorrow, though.

In case you didn't catch this: bold italic is Sirius, bold is James, italic is Remus, and normal is Peter.
