A/N: Hello again! Sorry I didn't write yesterday, I was kind of busy. I do have some social life you know, no matter how tiny. Anyway you know how I said I'd have two chapters ready by today- well I lied. Chapter 4 took a lot longer to write than I expected, and having writers block for most of this morning didn't help either.

Thanks again for all those who reviewed. You guys are great guessers by the way. Thanks particularly toKatherine-Emerald-Potter, SummerLovin9191 andHarmony'sSakefor reviewing two chapters in a row. You guys rock!

Anyway on with the story. Oh one more thing, I've been spelling Shacklebolt wrong throughout the whole of the last chapter- Sorry 'bout that I'll change it as soon as possible.

Disclaimer: I do not own anything you recognise, only the plot and Gemini Last chapter:

After the students whispers died down Kingsley continued his little speech, "And group three will be doing physical exercises taught by a new professor which some of you already know. Professor…"

As if on cue the double doors at the back of the room burst open revealing a man in long, black robes. Harry's mouth dropped open in shock.

Chapter 4

Just down the corridor Sirius Black bashed his head on his office desk- hard! Who ever had told him that becoming an auror was fun and full of action was wrong; very wrong. The young man looked down at the piles of paperwork that covered his table and sighed. Pulling the closest stack towards him he began reading.

" Great, just great! About 10 new people have joined the death eaters in one week alone whilst we have caught zilch; and Voldie's new tactic seems to be imperiusing young children and making them murder their own parents! Could the world possibly get any better?"

Sarcasm being one of Sirius' strongest points (as his dear mother had often pointed out) he sighed yet again; it seemed to have become quite a habit with him lately. The head auror began flicking through more files and folders without much conviction, allowing his mind to wonder freely and linger on his godson.

At the thought of Harry Sirius felt a strong bubble of guilt rise up from the pit of his stomach. The feeling had become strangely familiar over the past few days, ever since he'd found out who the new auror training professor was ad had neglected to tell Harry. Sirius himself had protested ad petitioned against employing him, but even as head auror he was out numbered.

He hadn't meant to hide things from Harry, he'd done it for the best, even Remus had agreed. It's just that recently the boy had appeared to be regretting his decision of being an auror for some unknown reason, and that knowledge might just have driven him over the edge. Either way Harry would probably be mad, and he has every right to be…

Sirius froze in mid thought. Something in one of the files grabbed his full attention- something in the 'lists and descriptions of all current know death eaters' file.

Right under Bellatrix Lestrange (surprise, surprise) there was another girl's profile.

' NAME: Gemini Laxcrosse

AGE: 35

NATIONALITY: British

CRIMES COMMITED: Murder of a family (two adults and one child)

ID NO: 19953476'

Below the details there was a small picture of a moon faced, olive skinned girl with dark, shoulder length waves. Despite being a death eater she certainly wasn't bad to look at, her grin in the picture showing a rather rascally look.

Looking at the photo Sirius saw not a death eater, not a killer, not a Voldemort supporter… but his first ever girlfriend!

Gemini Laxcrosse, a Griffindor in the same year as the marauders, one of Lily's friends to be exact. Gemini Laxcrosse, the girl who had dated Sirius Black for two months at the end of third year. True their relationship had only been a hilarious one of thing, nothing serious, but the couple had remained good friends afterwards (she always did have a good eye for pranking). Gemini Laxcrosse, a death eater?

Sirius was in a state of shock. This girl is as bad as Peter Pettigrew. They both betrayed their friends, their honour, Sirius, and what for? Some stinking dark lord! How could she do it? After all the times she said she'd hated the dark side! Had his friendship not been good enough?

Hurt, disappointment, rage, betrayal… Sirius was drowning.

-------------------------------------------------------------------------------------------------------

'Oi, Gemi, look at the stars. Aren't they beautiful!"

" Yeah they are beautiful, absolutely gorgeous. Look Siri I think I can see you up there- the dog star!"

It was eleven O'clock at night and whilst the rest of Hogwarts were asleep in their dorms this couple were lying on their backs besides the Great Lake gazing up at the stars. Although they had officially broken up over a year ago, stargazing was still a hobby they both still shared together.

" Siri, Sirius, look over there," no one could beat the bubble and excitement in her voice, " Those couple of stars look just like Lord Mouldie's arse."

Sirius laughed heartily; the girl next to him always did have a warped imagination. The stars, which she described as 'Lord Mouldie's arse', were nothing more than your average clump. Oh well two could play at that game.!

"Wall those ones next to Mouldie's ass looks like a demented death eater bowing down to his royal highness."

Upon hearing his words Gemini, rather than laughing, scooted closer to him on the grass.

She spoke in a low, crystal clear voice, "I think that death eaters are more stupid than Voldemort himself. At least he has his own mind, twisted as it may be. They are just puppets, ugly ones mind you."

-------------------------------------------------------------------------------------------------------

A loud rap on his office door brought Sirius back to the present. What was it with people interrupting his thoughts today?

" Come in," said Sirius regretfully, his mind still on Gemini's betrayal and whether Remus knew about it.

A short balding man entered Sirius' office, his clothes slightly frazzled as if he had just been running around the office. "Boss, there's been an attack in Diagon Alley. 10 death eaters raided the place. We don't know how many were killed."

Sirius stood up so fast that his chair nearly went flying across the room. All thoughts of Gemini were pushed to the back of his mind, at least for the moment. "Where abouts in Diagon Alley Dawlish." The head auror fought to keep his voice calm ad reasonable.

" Florish and Blots, sir"

Sirius clamped a hand to his mouth, his eyes wide in surprise. In a hoarse whisper his crocked, "Oh my God". Then dragging his hand away from his face to reveal a dropped jaw he added, " That's where Remus works."

Meanwhile in the auror training room striding down the isle and toward the front of the room was a certain greasy haired, hooked nosed, beady-eyed potions master.

The Golden trio looked around at each other in surprise. Severus Snape, Hogwarts' former potions teacher and living nightmare, what on Earth was he doing here? They all knew of course that the man had left the school of witchcraft and wizardry the same year as they had, to 'take up a different post'. Surely he wasn't the new auror teacher?

"For those of you who do not know this is Professor Snape, the former potions master at Hogwarts," boomed Kingsley's voice once again as soon as the latecomer had reached in line with them. " He will be group two's tutor, who are on physical exercises for today. Although Professor Snape himself is not an auror he does have all the skills required to teach you all successfully and we are very privileged to have him. Right now group one…

Kingsley's voice seemed to fade away into nothingness, along with Ron and Hermione's sympathetic glances, as Harry's emotions took over. It's like he's trying to haunt me, or something. Great, now I have to put up with him five days a week for a whole year. That means more taunts, more jeers…why don't I just quit training whilst I still can. I could always become a muggle healer or something. Or I could just get Sirius to get Tonks or Kingsley to change my group. No, that would give Snape the satisfaction of knowing that he's got to me. But speaking of Sirius why didn't he tell me that Snape was going to be teaching. He must have known that he's going to be here, he is the head auror after all.

Annoyance at everyone and everything spread like a fire through Harry's body. Snape's empty, grey eyes brushed across the room scrutinizing the young adults. His watch lingered for longer than necessary on a certain boy with a scar on his forehead. Harry forced his gaze upwards to meet the cold, calculating eyes he thought he'd never have to see again. A frosty, hard stare passed through the room, and Harry knew this next year would be his hell.

"Harry, Harry," Hermione nudged her friend, " Why are you just standing here? We're supposed to be going to our group places. Professor Shacklebolt told us about five minutes ago." At Harry's puzzled look she added, "Your group is supposed to go out to the grounds on the left of the building."

With an apologetic look and a 'Good luck mate, see you soon' from Ron, his two best friends left to go their own separate ways leaving Harry to trudge out on to the ground alone.

" Physical activity is not one to be cast of lightly in auror training. As most of you here probably do not have the skill to shield anything beyond basic hexes, in a battle situation you will probably be doing more dodging than anything else. Useless though that is, it can save your life not to mention that the unforgivables cannot be blocked using even an advanced shield. Discipline also…"

Severus Snape was already half way through his speech when Harry entered the grounds, which was basically about twenty acres of grass surrounded by a thick layer of trees.

" Ahh, Mr Potter, how nice of you to join us! And I was just getting on to discipline too. Wonderful now I can use you as a perfect example. Potter come here."

Harry was reminded forcefully of his first potions lesson with Professor Snape in his first year of Hogwarts. Anger boiled inside him as he thought of the memory. It was that anger that lead him to do something he would never normally do.

" No," Harry's voice was surprisingly quiet, all things considered. He could feel everybody's eyes on him boring into his skin and part of him just wanted to back down. But no, he'd let Snape walk over him for far too long, he was seventeen now not some little kid, it was high time he stood up for himself.

" No, I am sick and tired of you constantly picking on me. Why don't you pick some other dummy for a change?"

The dark haired professor had never looked so livid in his life. "POTTER," he barked. " Don't you dare act like that arrogant father of yours. The only reason you are still here and in my class rather than on the streets looking for another job is because your good-for-nothing godfather wouldn't chuck you out even if I told him to." Snape smirked before continuing, " But even he can't stop me from giving you 5 laps of the field, jogging. NOW! Any more funny comments and it'll be 10"

Harry's jaw dropped open in horror, much to the satisfaction of his teacher. The field was massive; one lap would be torture but 5…it would kill him. Fortunately, as angry as the teenager was, he bit back the many insults he wanted to through at Snape and instead turned round and started jogging with as much dignity as he could muster.

" Oh and Potter," Snape called to him forcing Harry to turn back round, " Just to let you know, you won't be having Lunch today. I need you to help me with…" his upper lip curled maliciously, "…Stuff."

It took Sirius a few minutes to absorb the fact that his best friend, his only other fellow marauder could be in danger- dying. It took him a few more minutes to get his self control back and not try to apparate straight to 'Florish and Blots' on his own.

Finally the head auror managed to croak out through the painful lump forming in his throat, "Dawlish, I need you to round up the rest of the squad and tell them to come here. Tonks and Kingsley are teaching, leave them be and Mad-eye's already on a mission. Be as quick as possible."

"Yes Sir," replied Dawlish before running out of the office.

As soon as he left the room Sirius sunk back down on to his chair and cradled his head in his arms. He just wanted to break down and cry- cry for Remus, cry for James, for Lily, even cry for Gemini and Pete- but he knew he couldn't. He couldn't let his emotions cloud this mission; and for all he knew Remus couldn't still be alive and well. There was still hope left. So why was Sirius tearing his hair out with his hands?

He didn't have long to grieve however because within minutes aurors started filling up Sirius' office wands in hand and faces set with a mixture of fear and determination.

Once he thought everyone was there, he took a deep breath and willed himself to start speaking, " Right is everyone here?" Upon hearing the low murmur of agreement he continued speaking, " There has been another attack by death eaters in Diagon Alley. This time in Florish and Blots." Sirius could feel the water build up behind his eyelids and quickly looked down to the floor.

" We do not have much details about the attack, or the severity of it; only that 10 death eaters were involved. Therefore I want us to corner the whole shop just in case.

I want Dawlish, Fanny and Greciech round the back, Harmison, Johan and myself will go up front and I want the rest of you to spread yourself around the rest of Diagon Alley in case you are needed. Got that?" There was a wordless nod around the room, so Sirius continued, "Good. In that case after one I want you to apparate to your positions. 3…2…1…" Pop!

Death eaters wearing, long black robes and masks dominated the streets… People screaming and running in all directions… A couple of dead bodies littering the floor; that's what Sirius Black had expected to see. But the sight that lay in front of him was far, far, worse. Never in 36 years had he seen Diagon Alley look like this.

The streets were deserted like in a ghost town. They were too late, the battle was over. Not a single soul could be seen or heard. At first glance nothing would seem drastically wrong, that is until you look up at the sky. Floating right above Florish and Blots was a large green skull, the dark mark.

The actual shop looked a mess! Many of the bricks were badly singed or burnt completely; the windows were cracked and the door blasted of its hinges; the show window, usually filled with neat books, was smeared in blood.

Upon seeing the sight all words of caution excited Sirius' mind, he did the first thing that came into his head- ran straight into the bookshop, ignoring the cries of Harmison and Johan behind him.

The moment he entered however he immediately started to regret it. The whole place was swimming in a pool of blood and a couple of dead bodies lay along side the fallen bookshelves and torn books. There was no sight of Remus anywhere though. However as Sirius entered the final room he saw a message written on the wall, 'The werewolf's blood shall be spilt and the dark lord shall become invincible'. The message was scrawled in red…in blood.

"MOONY!" yelled Sirius at the top of his lungs before fell to his knees and darkness enveloped him.

Harry Potter stumbled down the corridor until he reached a tall wooden corridor. Tiredly he murmured, "Verberat"- the password to Sirius' office and the door swung open. After his day of training had finished Tonks had approached him with a message from Sirius saying that some important work had come up and he, Harry, was to floo straight home from the head aurors office because Remus had gone to meet Dumbledore at Hogwarts. Of course Harry wasn't told what this 'important work' was, since Sirius didn't seem to want him to know too much about the war if he could help it.

The seventeen-year-old sighed as he slipped ungracefully out of the fireplace and on to the rug in the living room of his, Sirius and Remus' house. Today had to be one of the worst days in his life.

The laps had left him red faced, sweaty, out of breath and in complete agony. But he'd managed them somehow, even with Snape constantly on his back telling him to go faster. Most of the rest of the day was spent either doing either stamina building aerobics, push-ups being Snape's favourite, or simple dodging techniques. Neither of those would have been too bad (for quidditch had given Harry good reflexes as well a muscular endurance) if it wasn't for Snape's constant taunts about his dad, Sirius and his potion making skills. It wasn't only Harry who his tutor targeted, he'd successfully reduced poor Adiya Neola (a former Ravenclaw girl) to tears by the end of the lesson, it's just that Harry had it slightly worse than everyone else.

In fact some would say that it was a miracle that the hot-tempered boy hadn't lost it with Snape at some other point in the lesson.

The one good thing that did come out of the day was his detention at lunchtime. Not for the first time in his life Harry found himself to be the centre of attention; it seemed his little 'talk' with Professor Snape had spread round to all the students. And as nasty and disgusting cleaning a muddy assault course without magic, with Snape under your nose is, it still beats the questions he would have got from the other students.

As Harry yanked open the fridge door, ravenous (yes, a detention during lunch did have it's disadvantages) he heard the doorbell ring. Wondering if either Sirius or Remus were finally home Harry cautiously went to open the door with his left hand, his right gripping the wand in his pocket (he was well aware of the dangers death eaters possessed).

However standing on the other side, was not a death eater, not one of his guardians but a beautiful girl with long red hair. His girlfriend Ginny Weasley!

But even as he pushed the door open wider to give her a hug, she side stepped him and entered the house. "Oh my god Harry," she began speaking in a breathless tone almost immediately, " I know you must be worried but please don't do anything stupid. Remus is strong, I'm sure he'll be fine."

Spotting Harry's confused look she stopped talking immediately. The skin on his forehead was pulled into a frown and he spoke slowly, " Ginny, why would I be worried about Remus? He's only gone to Hogwarts to see Professor Dumbledore. Relax"

Ginny shook her head disbelievingly, her eyes watery and fearful. She hated being the bearer of bad news. "You mean you don't know?"

When her boyfriend shook his head confused, she continued speaking in a low voice, " Harry, I'm so sorry I don't know how to say this, but Florish and Blots was attacked this morning and Remus is missing. I'm sorry."

Her voice cracked at the end of the sentence, but that was nothing compared to Harry's reaction.

The boy stiffened visibly at Ginny's words and slowly his whole body started to shake. The pained expression on his face alone broke his girlfriends heart. It was several, long minutes before Harry spoke, ad when he did it came out as a hoarse croak, "Sirius said Remus…Hogwarts…No… He can't"

Smiling sadly, Ginny walked up to him and pulled him into a gentle hug. She could have sworn she heard between a sob, "I love you Ginny".

Meanwhile a long distance away in a tiny, damp cave, Remus John Lupin returned to consciousness to find a wand pointed at his blooded and battered body.

"Lupin, tell us where Potter is, or prepare to die."

A/N: How's that for a cliffhanger! That is my longest chapter yet! Did you like it? Please review and tell me. Pretty please.
