Disclaimer: I do not own Harry Potter or any other of J.K Rowling's creations. I don't own, you don't sue! I do however own Annabel as she is a character I have created.

My first Harry Potter fanfic so please review, I need help with ideas! Excuse my crappy spelling and grammar as well as I am only 15.

Note: It's now a 15 chapter fic. Upcoming chapter is 'Bachelor Party' chap 13.

Couldn't fit everything in 12 chapters so it's going to be 15 chapters long.

OOOOOOOOOOOOOO

Previously: Lily discovered James with Annabel (Sirius's ex-girlfriend) but was comforted by Sirius and has finally forgiven James. James doesn't know this yet.

OOOOOOOOOOOOOOO

Chapter 12: All's Fair in War

'Tomorrow is Hogsmead,' announced Sirius, entering James's darkened room and bouncing over to his bed.

'Go away,' replied James instantly, placing a pillow over his head. Ignoring James, Sirius turned his attention to the person lying next to him. Despite the darkness, the small slender form of Lily Evans could be seen.

'Well well. What do we have here?' chirped Sirius, ignoring James's desperate cries of protest.

'Sirius it is 3am, what do you WANT?' yelped James, causing Lily to stir. Eyes wide with recognition, James turned to the person lying next to him. 'Wait what's Lily doing here?'

'Your asking me? Didn't you two make up?' questioned Sirius, surprised that James hadn't even known that Lily was there before then.

'No. I haven't seen her since the eh thing with Annabel happened. I came up here and went to sleep,' replied James quietly, trying not to wake the sleeping Lily. He didn't understand why she was in his bed, he thought she was angry at him for making out with Annabel.

'Well she has forgiven you. I made sure of that,' Sirius retorted happily. James eyes widened but he looked at Sirius suspiciously.

'Are you Sirius?' James asked cautiously, knowing that Sirius could be joking. He didn't want his hopes raised to find out that Lily was still angry with him.

'Well why else is she in your bed? I hardly planted her there.'

'I wouldn't put it past you,' said James, laughing. Sirius pouted.

'Well if that's all I get for my good deed, then I wouldn't bother in future,' Sirius said, clutching his chest in mock hurt. James groaned and lead back down, wrapping his arms around Lily, ignoring Sirius's retching noises.

'Remind me again what you want,' hissed James coolly.

'I have come to inform you of my latest babe bonking plan,' Sirius smiled, dismissing James's jibe. He himself thought that his newest scheme was a stroke of genius, and he was eager to share his idea with his friend.

'At 3 o'clock in the morning?'

'Yes. As I was saying, you know tomorrow is Hogsmead-well it is-I'm planning on making my move,' droned Sirius, as James tried to bury myself under the blankets. It was hard enough to sleep with Remus and Peter down stairs talking, let alone when someone was talking right into your ear.

'Sirius if you don't shut up now, I will make you,' threatened James, interrupting Sirius's monologue, trying to bat him away from his bed.

'Hey this is not your dormitory anymore. You can't tell me what to do. If you want quiet then you can get out,' laughed Sirius, his eyebrows raised suggestively.

'Your kidding right?' replied James, suddenly looking at Sirius through wide eyes.

'Nope. Go on, get out! OUT, OUT of our dormitories!' Sirius yelled, causing Lily to wake with a start.

'What the-' she muttered, when a pillow swung out of nowhere and hit her in the face.

'GO ON. OUT!' cried Sirius, laughing his head off as he pelted Lily and James with pillows. They scrambled out of the bed and ran from the dormitories, Sirius hot on their tails, hitting them repeatedly over the head as they went.

'Sirius STOP. I'm going to kill you,' called James running through the deserted common room (with the exception of Remus and Peter), Lily right behind him.

'Well you should listen to me next time. Your going to have wait until tomorrow for my amazing plan,' grinned Sirius, stopping his attack and standing at the bottom of the stairs, as Remus and Peter watched the proceedings with amazement.

'Shame!' replied James sarcastically.

'OUT!' cried Sirius. Turning on their heels, Lily and James fled from the common room in search of the head's dormitories as Sirius continued to yell behind them.

OOOOOOOOOOOOOO

'Today is the day,' proclaimed Sirius, plopping down at the breakfast table the next morning, eyeing the food with hunger.

'What are you talking about?' asked Lupin, looking at Sirius with apprehension.

'The day to complete my dare. The ladies will not be able to resist me,' Sirius said, smiling eagerly.

'Whys that? You going to make a love potion?' suggested Lupin playfully. Sirius smiled.

'Wait. Your are going to make a love potion!' spluttered Lupin fearfully, choking on his cereal.

'That I am,' replied Sirius happily, piling his plate up with delicious food.

'You can't do that. That's like…like rape!' Lupin cried, staring at Sirius, his cereal forgotten. He couldn't believe that even Sirius would go that far. 'Then again, maybe he would,' Lupin thought.

'No it's not. I'm going to offer them a drink and slip it in. It just speeds up the process,' said Sirius dismissively while Lupin gaped at him, speechless. Trying and failing to say a something back, Remus gave up and returned to eating his cereal, still quiet with shock.

At that moment to very pissed off looking people approached the table. A very angry James and Lily glowered at Sirius.

'Have a good night sleep I hope?' commented Sirius, dodging James's punch that he received.

'That's a no then,' said Lupin, finally finding his voice.

'Yeah and who's faults that,' quipped James, pointedly staring at Sirius.

'It's in the past,' said Sirius, waving his hand dismissively. 'I've got something important to tell you.'

'He's going to poison a load of people,' Lupin told Lily and James suddenly.

'I think poison is a bit strong,' Sirius hissed, glaring at a stern looking Lupin. Lily and James glanced at each other apprehensively. Neither of them liked the idea of Sirius and poison in the same sentence.

'What are you talking about?' said James cautiously, looking from Sirius to Lupin, who were glaring at each other.

'Today you will find out my friend,' chirped Sirius, tearing his eyes away from Remus and plastering a smile upon his face.

'I don't like the sound of that,' said James…

OOOOOOOOOOOOOOO

Meanwhile watching the Marauders from the Hufflepuff table was none other than Annabel Harvey, who was growling in fury. She hated Sirius being happy without her, and was still mulling over her defeat. Sirius had played and manipulated her and so far had gotten away with it.

Her previous plan to hurt him had failed, causing James to bare the brunt of her wrath. During this she realised that she had genuine feelings for James but she had also witnessed James's loyalty to Lily. However Lily wasn't going to stand in her way. Annabel would have James if it was the last thing she did!

With this in mind, Annabel pulled a small glass vial out of her pocket containing a deep red liquid. It was the potion that would be perfect for her newest operation.

Operation 'Seduce James…'

To be continued…

I've decided to make it 15 chapter because I really enjoy writing this. The next chapter is 'Bachelor Party' chap 13 and is one of my favourite chapters. Sirius puts his love potions into action and James is cornered by Annabel with a certain vial. I'll update as soon as possible.

Please review and guess what you think is going to happen next. It's interesting to see if you'll guess it!
