Author's Note: Okay, this chapter is a little longer than normal, but don't get used to it!

Cassi sat in class. Bored was not the right word for what she was feeling at the moment. They had the misfortune of having this class with the Ravenclaws, which meant Alice was practically drooling over Frank Longbottom, and Marlene was too busy flirting with Benjy Fenwick to actually pay attention in class. It was Ancient Runes 1. Lily and Dorcas were already in Ancient Runes 2, and the Marauders, except for Remus, hadn't even tried the class.

Cassi stared out the window, watching the lake. She sat up as three animals ran across the edge of the Forbidden Forest, before disappearing into the trees. She bit her lip. She wasn't good at Care of Magical Creatures for nothing. She recognized the animals as a large dog, a stag, and the small blur on the stag's back as a rodent, maybe a mouse or a rat.

Turning back to the classroom, she thought about the time in fifth year she had seen the same animals. With a start she realized that it must be the infamous, mysterious pranksters, the Marauders. No one was sure what House they were in, but they were famous throughout Hogwarts for their pranks. Padfoot, Prongs, Moony, and Wormtail. Cassi had her suspicions, of course, everyone did, but no one could prove a thing.

The bell rand, signaling it was time to go to dinner. It was evening, and the sun was setting. Filing with the rest of her class to the Great Hall, she thought about Sirius again. It had been a month since he had told her that he loved her, and she had realized she loved him. She felt like it had been forever, that they'd always been like this, that all that hate and anger and sadness had never existed. She knew it wasn't true, but she felt like it was.

"Cass?" Lily spoke up.

"Hm?" Cassi was snapped out of her reverie.

"Have you seen James?"

Cassi stared at the red head.

"Did you just say what I thought you just said, Lils?"

Lily blushed angrily.

"We were assigned to do a project in Transfiguration, remember?"

Cassi thought back briefly to the week before, when McGonagall had assigned the project. She had been happy to be assigned with Sirius, but she faintly remembered laughing at Lily when she was assigned to be partners with James.

"Oh yeah…. I remember! That was funny!"

A smile broke across her face. Lily glared.

"It is not! Now I have to find him, because we need to go to the library!"

Cassi shook her head.

"Haven't seen him."

Lily sighed, blowing her bangs up.

"Well, have you seen Peter, Remus, or Sirius?"

Cassi thought.

"No, actually, I haven't. But I don't have class with them. So I don't know."

Lily groaned and stalked off to find James herself.

Cassi walked to her favorite seat. Normally, James, Peter, and Remus surrounded her and Sirius, but today, the four were nowhere in sight. With a thump, she sat down and began putting food on her plate.

It was getting late, and dinner was over. It was dark outside, and moon was a thin crescent. Cassi was worried, because she hadn't seen Sirius all night. She thought back to Drea's argument with him, which left her with one choice. To go ask Drea herself. Making up her mind, she gritted her teeth and followed the retreating Slytherins down the passage to their common room.

"Drea." The group that was the last stopped. Drea turned, arm in arm with Regulus, framed by Bellatrix and Narcissa, Rodolphus, and others. The Death Eaters in training, she and Sirius used to joke. She felt that acutely here in the dark passage, facing the worst of the Slytherins. Drea gave her a half smile, and Regulus a nod. In contrast, Bella gave a snarl and Narcissa a narrow eyed glare.

"Drea, I need to talk to you and Regulus."

Drea nodded.

"Just a moment, Narcissa."

The imperious blonde nodded regally. Drea walked up the hallway towards her sister. Regulus trailed behind her. Cassi turned and walked a little ways down the corridor so they couldn't be heard easily.

"Drea, Reg, have either of you seen Sirius?"

Drea dropped her head, and Regulus stiffened. He frowned.

"I haven't seen him, sister."

"Nor I, I assure you."

Cassi sighed.

"I thought you might've, I can't find him, and I'm worried."

"So you accused us because we're Slytherins?" Regulus snapped.

Cassi was taken aback. Regulus was usually level-headed and cool.

"Of course not," she said, "I just thought you might have seen him!"

"I don't associate with bloodtraitors. You of all people should know that, Sinclaire."

He put an arm around Drea and steered her away. She glanced back over her shoulder, eyes full of sadness and apology, at her sister. Cassi smiled sadly back.

Walking up to her common room, she passed the Entrance Hall. It was empty. Halfway up the stairs, she turned around, alerted by some noise. She saw three figures step out of the shadows and greet a fourth in low voices. The four hadn't seen her, so she crept back down the stairs and slipped into the shadows.

Edging her way around the wall, she came nearer and nearer behind them.

"Well, another run complete. I'm pretty sure that the Forbidden Forest won't be that bad if we go as the-"

"Shh!" the speaker was cut off.

Cassi backed up against the wall in horror. The voice had James, and the one who had cut him off was Remus. She knew, then, that the tallest figure could only be Sirius. She backed further into the shadows.

"Awh, Moony, it was nothing. You're hearing things." That was Sirius.

"No, Pads, I wasn't. Someone's here, someone right over there." He pointed towards Cassi. She couldn't help wondering how he had known where she was. She had been very quiet.

"Well, let's see." James started to walk towards her.

"James?" she asked before she could stop herself.

James reeled back.

"Cassi? Is that you?"

"Yes."

"Where you eavesdropping- CASSI?"

Cassi had taken off running. She hurtled up the white marble stairs. James started to go after her, but Sirius stopped him with an arm across the chest.

"I'll do it." He whispered.

He took off running after Cassi.

Cassi had taken refuge on the roof. It was her special place, the place very few people knew about. She knew that Sirius knew about it, and James, but she half wished they'd follow her so she could get rid of this anger that was coursing through her. She couldn't understand, but she felt an overwhelming sense of betrayal from Sirius. He had kept secrets, when she hadn't kept any.

She looked down at the bracelet she had just recently started wearing again. She was tempted to rip it off her wrist, but something stopped her. Instead, she sank against the roof and cried.

Sirius heard her crying, and that was how he found her, crouching on the roof, one hand clenched around the bracelet he had given her all those years ago. He approached carefully, as one might approach a wild lion.

"Cassi?" he asked tentatively.

Her head shot up.

"What do you want?"

"I wanted to make sure you were okay."

"I'm perfectly fine, no thanks to you, bastard."

"What did I do?"

"Sirius, do you have any idea how worried I was about you?"

She lifted her head, and let her tears sparkle across her cheeks. Sirius looked down.

"I didn't even think you'd notice."

"Of course I would notice!" Cassi was outraged. "How couldn't I? You would've noticed if I was gone for an entire evening! Or at least I thought you would've."

Sirius looked down.

"I guess I didn't think that out so well, huh?"

Cassi looked up at him, furious.

"NO SHIT, SHERLOCK!" she screamed at the top of her lungs. She stood up.

"I was worried about you, so worried I asked the bloody SLYTHERINS about you! I was alone with a bunch of Slytherins like BELLA for you, and you were off galivantining in the FORRBIDDEN EFFING FOREST!"

Sirius shrunk from her yells.

"Why were you so worried, Cass?"

"Why?" Tear rolled freely down her cheeks now. "Because I love you, you bastard."

With that, she stalked off, leaving a confused and worried Sirius, standing alone on the roof.
