A Potter/Black Alliance

1st November 1991

Harry groaned as he woke up. He was still feeling slightly tired after staying up until midnight following last nights events.

He sat up on his bed and looked towards where Joe was sleeping face down with his right hand hanging off the side of the bed clutching a now empty box of jelly slugs.

Harry then turned his head to look at the empty bed where their other room mate Cormac Mclaggen was supposed to be sleeping but had already woken up and gone downstairs.

He pushed some empty chocolate frog packets off his bedside table and picked up his wand.

"Tempus" said Harry groggily.

The time was 7:35 am.

Harry got up out of bed and walked over to Joe's bed shaking him slightly.

Joe slowly opened his eyes.

"What time is it?" said Joe sounding tired.

"25 to 8, come on we need to get ready, we need to make sure Weasley apologises to Hermione before going down to breakfast remember" said Harry walking over to his trunk to retrieve his towel and some clothes for the day.

Joe immediately followed suit and the two went to get ready for the day.

Once they were ready they made their way downstairs into the common room which was nearly full of most of the Gryffindor students. Hermione was dressed in a red jumper and black skirt and was sat on one of the settee's with 2 first year girls Harry recognised as Parvati Patil and Lavander Brown as well as Katie who was sat on the arm of the settee next to the brown haired Lavander.

Parvati had light brown skin with long black hair and was dressed in a black cardigan and jeans.

Lavander had curly brown hair and was dressed in a pink jumper and jeans.

Katie stood up and walked over to Harry and Joe dressed in a blue long sleeved shirt and jeans.

"Have they come down yet?" said Harry.

Katie shook her head.

"No not yet, I hope they haven't gone down to breakfast already" said Katie.

"They won't have done, everyone in this house knows what Ron did yesterday, they wouldn't have let him leave until he apologised" said Joe.

"Here he is now" said Harry nodding towards the boys staircase.

A dejected and worn out Ron walked downstairs followed closely by Neville, Dean and Seamus who like Ron looked upset.

They caught sight of Harry, Joe and Katie and slowly made their way over to them.

Harry and Joe stepped aside so the four could make their way over to Hermione who looked up to see them.

Harry, Joe and Katie turned to look at them as did the rest of the students in the common room.

Shortly before Ron was about to speak the portrait door opened and Professor Mcgonagall walked in dressed in her usual green witch robes and hat.

She stood near the entrance looking at Ron with a serious look on her face.

Ron nodded and turned back to Hermione.

"Hermione, I'm really sorry about yesterday, I said some nasty things about you when I know you we're only trying to help me in Charms, its my fault you ended up in the bathroom with that troll, if I hadn't been so nasty then you would never have been in that situation" said Ron regretfully.

Hermione managed a small smile.

"I'm sorry too Hermione" said Neville.

"Me too" said Dean.

"Sorry Hermione" said Seamus.

Hermione looked at them and smiled slightly.

"Could we start over, as friends?" said Neville.

Hermione nodded.

She stood up and hugged all four of them.

Harry smiled.

"Well, it seems like he might have finally grown up a bit" said Katie.

"You know what, I think your right Katie" said Harry.

Professor Mcgonagall walked up to Ron.

"Well Mr Weasley, I'm very proud of you for admitting your mistakes like that, but I'm afraid your actions yesterday cannot go unpunished" said Mcgonagall.

Ron nodded.

"20 points from Gryffindor and a weeks detention with me starting tonight, you three will be let off with a warning, use this as a lesson for the future when you're thinking about doing what Mr Weasley did" said Mcgonagall.

Neville, Dean and Seamus nodded.

Mcgonagall turned to address the house.

"I shouldn't have to remind you that Gryffindor House should be like your family while you are here, you should all be looking after each other, hopefully I will never have to explain this to you ever again, because if I do there will be serious consequences if something like this happens again, now make your way down to breakfast" said Mcgonagall turning and leaving the room.

Harry, Joe and Katie walked out of the common room and headed down to the Great Hall.

Alex and Susan walked into the Great Hall and made their way over to the Ravenclaw table.

They sat down with Alex making himself an English breakfast and Susan making some jam on toast. As they were doing this Daphne, Tracey and Blaise made their way over to them and sat down.

"Hey guys" said Susan.

"Morning, seems like everything is back to normal after last night" said Daphne.

"Yeah, wonder who let that troll into the castle in the first place, someone could've been killed" said Alex.

"Who knows, where would they even get a troll from in the first place" said Tracey.

"Well one things for certain, it couldn't have been a student" said Blaise.

"Are you saying one of the teachers did it?" said Susan.

"Maybe, all we know is that it couldn't have been a student" said Daphne.

"Which teacher would do something like that though?" said Alex.

"I don't know, but we'll have to keep an eye out for anything suspicious" said Tracey.

"I think I better write to Auntie about this" said Susan.

"I think you should" said Alex.

"Yeah, cos that was one mean troll" said a female voice from behind them.

They turned around to see Harry, Joe and Katie stood behind them.

Daphne and Blaise moved closer together to make some space for the three to sit down.

"What do you mean by that?" said Tracey.

"Long story" said Joe.

Alex looked at them with a serious stare.

"You guys went after it didn't you?" said Alex.

"Yeah, the damn thing had that Hermione girl cornered in the girl's bathroom, no teachers in sight" said Harry.

"I'm guessing she was hiding in the bathroom after what happened in Charms yesterday" said Alex.

"Why what happened?" said Daphne.

"Weasel got really jealous about Hermione doing the work when he couldn't" said Alex.

"Yeah, she overheard him badmouth her after the lesson and ran off crying" said Katie.

"Mcgonagall and all of Gryffindor house made him apologise to her in the common room this morning, not too mention he lost points and ended up in detention for a week" said Harry.

"Serves him right" said Susan.

"Yeah, though by his reaction last night and this morning he regrets what he did, I think he might've grown up a little bit as well" said Joe.

"Seems to be getting along really well now" said Tracey gesturing towards the doors with her head.

Neville, Ron and Hermione had just walked in together chatting amongst themselves.

"Good, he was making our house look bad" said Katie.

"Yeah, Hermione looks remarkably calm for someone who went up against a mountain troll last night" said Blaise.

"Yeah, can't imagine too many first years would be that calm after what happened" said Susan.

"Especially muggleborns who are new to this world" said Daphne.

"Yeah, but whoever let that troll in has got a lot to answer for" said Joe.

"Pity that Dumbledore will be spending more time trying to find out who pulled that brilliant prank last night instead" said Alex smirking at Harry.

"One of our finer moments" said Harry proudly.

"Dad will love to hear that, what did you do to Snivillus anyway?" said Alex.

"Amortenia, no idea how Fred and George got their hands on that" replied Katie laughing slightly.

Alex, Susan, Daphne, Tracey and Blaise laughed.

"I'll get the mirror from my room then we can tell him all about it, mum's gonna kill you though" said Alex chuckling.

Harry looked slightly nervous.

"Come on lets finish eating then we'll take a walk" said Susan.

They finished their breakfast and left the Great Hall. Alex walked up towards Ravenclaw Tower to get the mirror while the others walked outside the castle gates and over the wooden bridge sitting down on the hill overlooking the Forbidden Forest.

Alex returned about 30 minutes later with the mirror and sat down next to Susan and Blaise on the grass.

He held the mirror 6 inches in front of his face.

"Padfoot" said Alex.

A face appeared in the mirror but not the one Alex and the others were expecting.

"Alex, this is a surprise, your Dad's just had to pop into work for a bit, he'll be back soon though" said Marlene who was still dressed in her blue nightgown.

"Hey mum, where's Dorcas, I'd have thought she would have jumped at the chance to talk once she heard the mirror?" said Alex.

"She slept at Greengrass Manor last night, she's coming back around 12, how are you, are you and Harry keeping out of trouble?" said Marlene.

"I am, can't say the same about Harry though, he's got a few things to talk to you and Dad about" said Alex handing the mirror to Harry who took it and brought it to his face.

"Auntie" said Harry smiling.

"Harry, what trouble have you gotten yourself into now?" said Marlene sternly but with a small smile on her face.

"Some good and some bad, it will be better if Padfoot heard this as well" said Harry.

Just on cue Marlene turned towards the door as the faint sound of the fireplace could be heard from the mirror.

They heard a faint voice shouting asking where Marlene was to which she replied "In the upstairs sitting room Sirius".

Footsteps grew louder 30 seconds later as Sirius's face appeared in the mirror.

"Hey prongslet, what's up?" said Sirius smiling at his godson.

The others snickered at Sirius's name for Harry.

"Not much, had an eventful night, which I need to talk to you about actually" said Harry.

"Good or bad?" said Sirius.

"Both" said Katie who leaned on Harry's shoulder so she could be seen in the mirror.

Sirius and Marlene just looked at each other.

"Which do you want first, the good or the bad?" said Harry.

"The good" said Marlene.

Harry told them all the details about his prank on the faculty with Joe and Katie adding details as they went along.

At the end Marlene was straining to contain her laughter while Sirius was rolling around on the floor in laughter after Harry had told him about Snape.

"Harry, as funny as that was, be careful in the future, you could get in a lot of trouble if your caught, especially for the use of Amortenia, that's enough for an expulsion" said Marlene who cracked a smile.

Sirius eventually got up off the floor.

"Oh merlin, I wish I could've been there to see that" said Sirius still laughing.

"Yeah it was great, and don't worry Auntie, no one will figure out it was us" said Harry.

"Okay now that that's over and done with, what about the bad news" said Marlene in a serious tone.

"Harry looked at Joe and Katie who nodded.

"I think it might be better if you heard this from all of us" said Harry.

Marlene and Sirius looked at each other with a worried look on their faces.

Katie levitated the mirror away from them so Sirius and Marlene could see all of them.

Harry, Joe and Katie told them all the details about the troll attack and how none of the teachers have mentioned it since.

By the end of the story Sirius and Marlene both looked angry and shocked by the story.

"You should've got help from a teacher, not foolishly rush off to fight it yourselves" said Marlene.

"There we're no teachers in sight by the time we realised where Hermione was, if we spent ages looking for one then she might have been killed before they got there" said Harry.

"This isn't good, the DMLE are going to go nuts when they hear about this, which we should've done by now, but no one said anything about it when I was there" said Sirius.

"I doubt Dumbledore was going to tell them dad, he'll want to keep this quiet" said Alex.

"Susan, could you write to your Aunt and tell her what happened" said Marlene.

"I was planning to do that this afternoon, she'll be fuming with Dumbledore about this" said Susan.

"All right, we'll let you guys get off, try and stay out of trouble in the future Harry" said Marlene smiling.

Harry laughed.

"I'll try, but no promises" said Harry.

"Look after yourselves, all of you, we'll see you next weekend as well for your first match Harry" said Sirius.

"Bye, mum, bye Dad, love you both" said Alex.

"See you next weekend" said Harry.

The rest of the group said their goodbyes before Katie levitated the mirror back towards Alex who took it and placed it in his pocket.

They stayed on the hill for the next 2 hours talking about school and making jokes about the victim's of Harry's and the others prank before heading back up to the castle.

They sat together at the Gryffindor table for their lunch before Alex and Susan walked back to the Hufflepuff dorms to get a quill and parchment intending to write a letter to her Aunt.

She sat with Alex in the library writing the letter while Alex started on his Potions homework.

Dear Auntie

Life has been great here at Hogwarts for me and my friends, I love it here but secretly I can't wait to be back for Christmas.

Anyway I think you need to come up here with a team of Auror's. Someone let a mountain troll into the castle on Halloween night which came close to killing a first year student. We just spoke to Sirius who told us that the Auror office hasn't been notified of this.

Hope to hear back from you soon.

Miss you

Susie

Susan folded the parchment up and placed it in an envelope she brought with her.

"Finished" said Susan.

"Give me a few seconds, just got to finish this paragraph then we'll walk up to the owlery, you can send it with Hercules if you want" said Alex writing on a roll of parchment.

"Thanks Alex" said Susan smiling.

"Done, lets go" said Alex standing up and putting his work back in his jumper pocket.

He offered her his arm.

"Shall we?" said Alex.

"We shall" said Susan smiling taking his arm.

The two left the library and headed to the Owlery.

After sending the letter off with Hercules they walked back into the castle where they saw Hannah and Sally-Anne Perks sat on one of the benches where Sally-Anne was clearly upset about something.

They made their way over to the pair.

"Sally, what's happened, what's wrong" said Susan.

Hannah turned to look at her.

"Malfoy, we were just walking when he tripped her in the corridor, when I helped her get back up he just shouted at her before walking off laughing" said Hannah in anger.

"What did he say?" said Alex looking angry.

Hannah stood up and walked over to Susan and whispered in her ear. Susan's face changed from one of sadness to one of pure anger.

She leaned over to Alex and whispered in his ear.

"He said filthy mudbloods don't belong in our world and should be driven off like cattle, she doesn't know what it means but as we can see its really upset her"

Alex snarled.

"That bastard, just like his Father" said Alex angrily.

"Who's just like his Father?" came a voice from behind them.

They turned around to see Harry stood there with Joe and Katie with a look of confusion on his face.

"Malfoy, he called Sally-Anne a mudblood" said Susan quietly.

"That boy doesn't know when to keep his mouth shut, leave it with us, we'll deal with Malfoy" said Harry.

"Deal with him how?" said Hannah.

"Give him a lesson he won't forget" said Harry.

Katie walked over to Sally-Anne who was still slightly crying.

"Ignore what he said Sally, he's not worth getting upset over" said Katie placing her hand on Sally-Anne's shoulder in support.

Sally-Anne nodded.

Katie walked back to where Harry and Joe we're stood. The three said their goodbyes before walking back into the castle.

A few hours later Harry and Katie were stood near the entrance to the Great Hall with looks of impatience and anxiousness on their faces.

"What's taking him so long?" said Katie.

"He won't have been caught, we'd have heard if he was" said Harry.

"No I haven't been caught, it wasn't easy to slip the potion in his drink without that Flint guy seeing though" said Joe pulling Harry's invisibility cloak off of himself.

He handed it back to Harry who called for Kreacher to take the cloak back up to his room and put it in his trunk.

The three walked into the hall and sat down near the Weasley Twins and Lee Jordan.

30 seconds later a voice caused them to look up.

"Can we join you?" said Daphne.

She was stood with Tracey and Blaise looking at the empty seats next to Lee Jordan.

"You don't need to ask, of course you can" said Harry.

The three sat down and helped themselves to food and pumpkin juice.

A few minutes later shouts from the Slytherin table caused everyone to turn and look at said table.

Draco Malfoy had just been sick all over his plate and the nearby food and was about to be sick again to the disgust of other Slytherin students.

Crabbe and Goyle just sat their clueless and unsure what to do until Malfoy managed to stop vomiting long enough to tell them to help him. As the pair hoisted him up and walked him out of the Great Hall Snape stood up and strode after them with a murderous look on his face.

The rest of the students including a few Slytherins were laughing their heads off at what happened.

"Well you made good use of that potion then Joe" whispered George.

"He had it coming" said Joe smirking.

Meanwhile at the Hufflepuff table.

"I guess that's what Harry meant by deal with him" said Susan quietly to Alex.

"Yeah, shame Mum might tell him off for that though, she may not like Malfoy but she won't tell Harry she would've liked that, he's gonna get in some trouble next time they speak" said Alex.

"Surely your mum won't tell him off too much" said Susan.

"She won't she'll just pretend to be angry at him instead" said Alex.

Susan laughed.

8th November 1991

Harry and Katie were sat holding their brooms in the Gryffindor team tent dressed in their quidditch robes along with the rest of the Gryffindor team Oliver Wood, the Weasley Twins, the blonde haired 3rd year Alicia Spinnet and the dark haired 3rd year Angelina Johnson.

Their robes were red matching the colours of Gryffindor house with leather pads covering their chest and arms.

"Right we today is our first match of the year, the year which we can hopefully end with winning the quidditch cup, we know how good we are, so lets go and prove it" said Wood.

Harry and the others stood up making their way out of the tent towards the pitch entrance.

Harry and Wood stood at the front with the twins behind them and Katie, Alicia and Angelina stood behind them.

"Ready" said Wood mounting his broom.

Harry mounted his broom and they all kicked off the ground flying through the entrance to an enormous applause.

The stadium was basked in a sea of students with most wearing the red and gold of Gryffindor and the rest wearing the green and silver of Slytherin.

The Slytherin players were already in the air in the centre of the pitch wearing near identifical robes except they were green instead of red.

The Gryffindor team flew one lap round the pitch together before going to join their rivals in the centre. Harry flew up towards where the Slytherin seeker was hovering and hovered directly across from him.

He looked around the stadium and saw Sirius, Marlene and Dorcas sat with Amelia and to his surprise Astoria. Astoria and Dorcas were both wearing red jumpers and were holding a banner saying "Lions rule" between them causing Harry to chuckle.

He gave them a smile and a small wave before turning back to face the Slytherin seeker.

He heard the sound of Lee Jordan from the teachers stand.

"And now introducing the Gryffindor team, Oliver Wood, Fred Weasley, George Weasley Katie Bell, Alicia Spinnet, Angelina Johnson who still won't go out with me no matter how many times-" shouted Lee.

"JORDAN!" shouted Mcgonagall from next to him.

"Sorry professor, and lastly Harry Potter" shouted Lee.

Most of the stadium erupted into applause while Harry did a backwards loop on his broom when his name was called.

Madam Hooch walked into the centre circle with her broom in her hand.

"Now I want a nice clean game, from all of you" said Madam Hooch sternly fixing her eyes on the Slytherin captain Marcus Flint with that last sentence.

She opened the box releasing the bludgers and the golden snitch which flew past Harry and the Slytherin seeker before flying high into the sky.

Madam Hooch picked up the quaffle and threw it upwards towards the players starting the game.

Harry drifted away from the Slytherin seeker scouring the pitch for the snitch as Angelina Johnson caught the quaffle and soared off towards the Slytherin hoops.

"Johnson, to Bell, to Spinnet, back to Bell again, across to Johnson!" shouted Lee as cheers erupted from the Gryffindor students as Angelina Johnson launched the quaffle through the left hoop beating the Slytherin keeper.

"10-0 to Gryffindor" shouted Lee.

Harry gave a little clap before going back to searching for the snitch.

Around 20 minutes later as Gryffindor were 60-20 in front Harry spotted the snitch whizzing past the Slytherin hoops and took off after it.

"Potter's on the move, has he spotted the snitch" shouted Lee as Harry neared the Slytherin hoops while the snitch took off into the air again.

Harry followed it as the Slytherin seeker ended up next to him and shoulder barged him. Harry did the same thing with the two barging each other back and forth while following the snitch around the pitch as they approached the large tower where Sirius and the others were sat.

The Snitch suddenly dove towards vertically towards the ground with Harry and the Slytherin seeker following it all the way down.

The crowd oooh'd and gasped with anticipation as the two got closer and closer to the ground. Eventually the Slytherin seeker couldn't take it any more and pulled out of the dive 20 feet from the ground.

Harry kept going and pulled his broom up bringing himself level 8 feet from the ground.

Harry surged his broom forward getting closer to the snitch and reaching his arm out. Just as he was was fingertips away from it the snitch prepared to rise into the air again but Harry quickly snatched it.

"Harry Potter caught the snitch, Gryffindor wins 230 to 50" shouted Lee to a thunderous applause from most of the stadium.

Harry soared into the air into a group hug with the rest of the team before flying over to where Sirius and the others were sat. he dismounted his broom and received hugs and congratulations from them before flying back down to the ground with the others.

They all walked back to the changing rooms cheering and laughing about their victory.

A/N: Well I'm pleased to say that now I am finished with my Uni work that there will be more updates for all of my stories in the coming weeks.
