Disclaimer: If I said I owned this, my nose would grow. A lot.

Summary: So what goes on inside the brilliant mind of a certain Lily Evans? She's Head Girl…she's respectable…she's intelligent…she writes an awful lot about a certain dark haired boy….and she's most likely going slightly insane.

A/N: You know, I never thought this story would be 15 chapters long. And here it is, fifteen chapters. It's crazy. Oh, I almost forgot. I went back and read the entire thing and I noticed that no one ever commented on all of the Marauder's Halloween costumes. Some commented on Dumbledore's (which was a sock…which was obvious). I'll now explain my crazy hidden meaning in them.

Sirius: he was a dead/zombie soldier. Cut out the zombie part and then remember the end of book five.

Remus: He was dressed in a toga. This is simply drawn from his name which is Remus. Ever heard of Remus and Romulus? Oh and get this…they were raised by a she-wolf…J.K Rowling is so cool. I love all the meanings behind the names.

Peter: ok, this is an easy one. He was dressed as a rat. His animagus is a rat. Oh hey, and he IS a filthy rat who 'ratted' out James and Lily's where abouts. Grrrrr…..

Anyways, enjoy this chapter!

The Diary of Lily Evans Chapter Fifteen

History of Magic – Not paying attention.

Sirius and Chelsea sitting in a tree, K-I-S-S-I-N-G! First comes love, then comes marriage, then comes the baby in the baby carriage!

Ha! Riiight. Sirius…married?

Who knows, you may be the girl to change his bachelor ways.

I doubt that. I just like him so I'm willing to take all I can get.

Oh be more optimistic.

Sirius isn't James, Lily. James would have married you back in fifth year. Sirius will always be a bachelor. And honestly, I don't know if I'd want to be tied down either. I like freedom.

Yeah, yeah, Miss. Flirt. Anyways, you're still going on a date, right?

Yeah of course. We haven't picked a day yet though.

Hm…I see.

What about you and your husband? It's been a week since you've written in here.

Well I've been busy.

Yeah, with your tongue down Potter's throat, no doubt.

I resent that.

And yet you don't deny it…

…hehehe…

Hahaha, I love it when you get embarrassed. Your face goes redder than a stop sign.

Oh sod off.

Charms – URGENT!

Lily! LILY!

What? What's wrong? I only just sat down.

I was talking to Sirius in the hallway.

And I was talking to James…so?

Well I asked him about going on a date tomorrow night and he got all panicky and said that he couldn't.

I see. I thought this thing with Sirius wasn't a big deal to you?

Well ok, so I lied a bit. I at least want to go on ONE date with him before I'm tossed aside.

Ha! I knew it. Ok, well he just said he couldn't tomorrow night. Did you offer another day?

Well…no. But neither did he. He just hurried inside!

Hmm, I wonder what's up. He didn't say why he was busy?

No…Maybe he changed his mind? Maybe he doesn't want to go out with me anymore?

I doubt that.

Lily, what should I do?

I'll talk to James.

Gryffindor Common Room – going to talk to James

Hm…where is James?

Oh there he is.

Chelsea's really worried about all of this. I don't blame her. I'd be worried if James told me he was busy but didn't tell me why. Not that he ever would. Thank Merlin.

"Hey James," I say, smiling at him and then to the other Marauder's at the table, "can I talk to you for a sec?"

"Yeah, sure, what is it Lily?" James asks, as we make our way over to a quiet corner of the common room.

"Sirius still wants to go out with Chelsea, right?"

"Hell yes. He hasn't stopped talking about her. Why do you ask?"

"She just freaked out cause he said he was busy tomorrow night and never said why."

"Oh, see."

Is it just me, or does James look a bit panicky?

"James," I say.

"Yes, Lily?"

"Do you want to do something tomorrow night?"

I know I'm being blatantly obvious in my scheming here, but I don't care because I swear James looks freaked out now.

"Um…I'm sorry Lily, but I can't."

"Why not?"

He knows this is a test. He can tell. He's sweating.

"Well…all of us Marauder's are busy…um…well…planning a prank."

I eye him warily.

"Why didn't Sirius just tell Chelsea that?"

"We like to keep our pranks secret," James says, looking slightly more confident, "So please, don't say anything. You can tell Chelsea to calm her down, though."

My eye's narrow. There's something odd about this.

"All right," I say as I smile and kiss him on the cheek, "See you later James."

Divination – Discussion in Progress

There's something wrong here, Lily.

I know. But what can we do about it?

Well…we could…oh never mind.

What?

No, it's a stupid idea. It will only get us in trouble. Just like all of my other ideas.

Well true, but mine aren't much better, and the last one didn't end so badly.

Yeah but this one is…well it's just not a good thing.

Oh. Well I guess we'll find out tomorrow morning if they lied.

Yeah. For once, I really hope they pull a prank.

The Grounds – A STUPID Spy Mission

I can't believe we're out here. What were we thinking?

I saw them out here. I just looked out the window and there they were, running across the grounds in the middle of the night.

Because they're pulling a prank…

Right, of course. But there's no harm in checking.

We really shouldn't be doing this. I'd go ballistic if James followed me around secretly.

That's why I didn't suggest this before…but I HAVE to know what's going on.

Did you see where they went?

No. I'm switching this over to documenting mode.

Documentarium Spell: Recording

Lily, stuffed her diary in her pocket and huddled slightly closer to Chelsea.

"I'm not sure about this, Chelsea. It's too quiet," Lily said, shivering.

"Yeah, between the shivers I'm getting and the full moon, it's pretty freaky out here," Chelsea acknowledged, wrapping her cloak even tighter around herself. She didn't notice that Lily had stopped walking and was now looking up at the sky.

"The full moon…" she murmured, a sudden look of horror dawning on her face.

"What? What is it Lily?" Chelsea asked, coming to stand closer to Lily.

There was a sudden howl heard in the distance.

"Oh my gawd, we're so stupid. How could I not have noticed?" Lily said under her breath.

"Lily? What's going on? What was that noise?"

"It's…It's Remus. Come on, we have to get out of here."

"Wait, what are you talking about?" Chelsea said, grabbing Lily's arm as she turned to run back to the castle, "I don't get what's going on."

"We don't have time! We have to get out of here! NOW!" Lily yanked Chelsea after her as she began to sprint up to the castle.

"What? Lily I don't---"

A crash and another howl was heard from the trees at the edge of the forbidden forest. Lily froze in her tracks and looked back. There, staring directly at them, was a wolf. A werewolf.

"Is that…what I think it is?" Chelsea asked, her voice shaking slightly.

"Well, that depends on what you think it is," Lily said as she grabbed Chelsea's hand and started running again.

"But Lily, does that mean that Remus is a…?" Chelsea trailed off as Lily yanked her up the hill.

"Unfortunately."

That's when they heard the growling and the lumbering of a large animal chasing after them. Then, there was barking. Chelsea turned to look just as a big black dog jumped and caught the werewolf in the middle, throwing it off course. Lily had stopped running also, but for another reason.

A large stag stood in from of her, a panicked look in it's eyes. Lily stood, dumbstruck, as her brain suddenly put everything together.

"Prongs….James…" she whispered, "so that's how you do it…animals won't be affected if they get bit…"

The stag almost seemed to nod, and then noticed something behind them. Lily spun around.

There, loping across the grounds was the werewolf advancing on them quickly. The shaggy black dog was chasing it, trying desperately to catch up.

"Padfoot…Sirius…" Lily muttered. Chelsea backed up beside Lily as the powerfully built stag put it's self between the werewolf and the girls. Padfoot was gaining on Remus, but he would reach James and the girls first. The werewolf lunged, attacking the stag.

Lily screamed and would have run to James' aid had Chelsea not stopped.

"Are you crazy?" she yelled, "You'll be killed!"

Lily was crying as James fought off the werewolf, bucking and galloping, trying to lead it away from the girls. The werewolf lashed out, striking the stag's side and causing a large slash to open up and blood to spill out.

Lily screamed, tears pouring down her face, and wrenched herself from Chelsea's grasp. She ran to James and bent over him, "James! Oh my gawd…" She ripped the sleeve of her cloak off and pressed it to his wound. James, she noticed, was starting to change back to his normal self.

The werewolf was advancing slowly on it's prey, but Sirius had finally caught up and threw his self at it again, this time biting it on the back of the neck and dragging it away. The two animals soon disappeared into the forest.

James was lying on the ground, blood seeping from the gash in his side.

"Oh James…I'm so sorry…I'm so stupid…I shouldn't have been out here but I forgot about Remus and---"

"You knew?" he asked, his breathing ragged.

"It doesn't take a genius to figure it out."

James smiled weakly. Chelsea stood nearby and was looking nervous and confused.

"Chelsea? Maybe you should go and get a teacher?" Lily suggested gently.

"Yeah…good idea…" she said, then scurried off to head up to the school. Lily turned back to James.

"Are you alright?" she asked quietly.

"I've been better."

Lily smiled and brushed his hair away from is eyes, "I was so scared."

"Me too."

Lily laughed slightly.

"Gawd, why does everything seem to be going so horribly this year?" she asked, looking up at the sky, as if it would give her the answers.

"Things aren't that bad, are they? I mean, look at us, we finally got our act together."

"That seems to be the only good product."

James smirked. Lily saw Sirius, still in his dog form, coming up the hill, covered in scratches. Peter soon appeared as well.

Lily paused and then pulled her diary out of her pocket.

"What's that?" James asked. He tried to sit up to see better, but yelped with pain and laid back down.

"Nuh, uh mister, don't you dare try to sit up."

"But what is that?"

"This, I believe, is the cause of this whole mess. It's also known as my diary."

"Why would it be the cause of all this?"

"I think that it made me go insane."

"Lily, I don't think you needed any help," James said, smirking wryly.

"I would hit you, but you're already injured enough."

There was a long pause. Sirius had flopped down beside Lily and James, back in his human form. Lily could see Chelsea and Dumbledore hurrying across the grounds towards them. Lily looked down at her diary thoughtfully.

"I don't Ineed this any more."

"What do you mean?" James asked curiously.

"I think it's served its purpose."

Even Sirius looked interested now.

"And I think Chelsea would agree," Lily added, pulling out her wand as she stood up. Dumbledore made his way over to James, followed by Madam Pomfrey who had hurried outside as well.

"I'd agree with what?"Chelseaasked, coming to stand beside Lily and peer down at the open diary.

"That we should retire this diary."

She paused thoughtfully for a moment.

"Maybe you're right. We've documented what we set out to document."

"Yep."

"And if something monumental happens, there are still a few pages left to fill."

"What qualifies as monumental?" Lily asked, raising an eyebrow.

"Oh I dunno…maybe a wedding to a certain James Potter?"

"You, Chelsea Fanrae, can just sod off."

"Well it's gonna happen. You ARE dating."

Lily smirked and waved her wand over the diary, muttering a spell under her breath as they made their way up to the castle.

Documentarium Spell: Terminated

A/N: Ok, so I'm sorry it's taken me forever to update. You're all wonderful reviewers and if you all review TONS…then I may just add a nice little epilogue that will be some fun and funny fluff. One guess what it will be about….

Anyways, review, and be sure to check out my new story "Washing James' Whites" when I eventually get it written and posted….
