Hi, so here is another chapter, this one is the first part of the book chapter Through The Trapdoor and will be continued in the next chapter of this fanfic.

Also it was a lot of fun to have Dumbledore give the hint for Calla. I know in the book all the credit goes to Hermione but this was a lot of fun to write.

Some events skipped over and changed but most of this is still the same.

Disclaimer-Nothing is mine.

Please Read and Review.

And They Lived

Chapter 11-The Singularity

The gang sit their exams as they realise their time is up, Dumbledore gives a cryptic hint, Harry has a plan, and Calla finds her courage. Meanwhile in the Ministry, James and Sirius run into Dumbledore and realise something is wrong at Hogwarts.

Chapters Covered-Through The Trapdoor-Part One.

The weeks after their excursion into the forest were dedicated to exam revision. They were upon them and neither Harry nor Ron could find excuses not to revise though Calla had been exasperated and amused to hear Ron's plan to coast through life on a combination of his good looks and Harry's fame. They spent most of the weekends in the library and Hermione had begun pulling out her old notes with a frightening expression on her face that told Calla that she was going to learn all of it and probably a bit more.

Harry and Ron started studying on the Quidditch pitch and Hermione had gone to the library. Calla had just gone and sent an owl to Uncle Remus not only enquiring about what she suspected would be on her History of Magic paper but also asking if he was alright after the last full moon. So, she was walking back to the common room her head in a book when she all but ran into someone and judging by the fact that, that someone was taller than her and dressed in a royal blue robe embroidered with silver stars she knew who it was. Her books tumbled out of her arms and onto the floor with a loud bang as she looked up.

There was only one person in this school that was dressed that way.

"Ah Miss Black" Professor Dumbledore cried. "What a wonderful coincidence"

Calla highly doubted that. Professor Dumbledore did not wander around hallways looking for coincidences. He had come to her for a reason and Calla with all the fear that was still held by students who had either lived through or remembered Voldemort's first reign of terror suddenly wondered if there was a reason why he had come to her.

"Is my Dad ok? Is it Mum? Has something happened?"

Professor Dumbledore blinked at her and then smiled shook his head.

"As far as I know your mother and father are both fine. I am merely wandering the halls at my pleasure. Sometimes I get board in my office Miss Black and I desire to see my students in action, all those young minds cramming over their books. As I see you are" he said and with a wave of his wand Calla found her books back in her arms and her Herbology manual on top.

"Ah Herbology" Professor Dumbledore said that strange twinkle in his eye. "A wonderful subject. I find the plant Devil Snare to be one of the more interesting ones. Well I must go…Professor Snape I believe wishes to see me though I doubt it will be a very pleasant conversation. Good day Miss Black"

And then he was gone down the corridor in a swish of blue and silver.

Her Dad was right Calla thought, Dumbledore was insane.

Still that night she read over the paragraph of Devil Snare in her book just in case it came up on the test the following day. It didn't of course but she still couldn't shake throughout the entire week that there was a reason why their headmaster had gone out of his way to tell her that she should read up on Devil's Snare and the fact that it sulks in the sun. Calla didn't tell anyone and she thought that she managed to get good grades on everything and she didn't tell anyone the fact that Dumbledore had told her to look up a plant that had no buisness being the exam for the first time.

Still she supposed it couldn't hurt for next year.

Harry was thinking hard. Ron had just snapped at the girls who were both going through their past History of Magic papers that, that sort of behaviour made him feel ill. They had finished their exams and they had a glorious week or so in which they could forget all about them. He watched an owl fly across the sky and turned his attention to Hagrid.

And then it hit.

He stood up, he was barely aware of Ron, Hermione and Calla following him their bags in their hands and their ties loosened up the grassy path where he was shelling peas. He felt feverish, he felt like his very skin was on fire not just his scar. He felt like he was on the edge of something, that tonight something was going to happen that was going to change his life forever.

Who did walk around with dragon eggs in their pocket, who knew that Hagrid had wanted one for years. Snape would know. And he would also know that Hagrid was a soft touch when it came to drink. Everyone knew that, even his father knew that. Harry heard Hermione's soft gasp and knew that she had reached the same conclusion that he had done and then Hagrid said the words about that bloody three headed dog that was his pet that made all four of them freeze.

"Play a bit of music and he falls right asleep"

Calla swore loudly, and Ron's mouth fell open and Harry saw the look on Hagrid's face drop as he just realised the consequences of what he had not only told them but told the stranger. Finally, Harry felt the entire puzzle come together, all of what they had seen and heard and stumbled across this year coming to a head, coming to a screeching stop.

And then he was gone.

He was running back through the grounds and he was only aware that Calla was behind him because she could outstrip most people in running, he skidded to a stop in the entrance hall, Calla skidding neatly to a stop next to him and Ron and Hermione bringing up the rear both panting and clutching their sides. There was a pause where he stood there and looked around trying to see something that wasn't Voldemort coming back, getting stronger, trying to take over the wizarding world again, coming after his mum and dad again. He looked at Calla and Ron and could see the same fear reflected in their faces. Sometimes Harry envied the fact that Hermione had never known this kind of fear that still gripped the Wizarding World today.

"It wasn't a stranger he was talking to it was Snape" Harry said finally. "We have to go to Professor Dumbledore"

But Professor Dumbledore was already gone.

"Right" Ron said. Apparently he was taking charge now. Hermione after their confrontation with both Snape and McGonagall was looking very nervous and Calla had gone white again. Harry was gazing across the pitch but his eyes were glittering with something Ron had never seen before and didn't want to see ever again.

"Well this is what we've got to do, Harry and I will go to the third floor and check that Fluffy is still there and growling, Hermione follow Snape and make sure that he stays either in his office or in the staff room and Cal…Cal what do you want to do?"

"I think" Calla said finally. "Now is the time to bring in my Dad. With Dumbledore gone…he should at least know that someone is after the stone…if Dumbledore is at the Ministry then he can go find him and let him know"

Ron nodded. Finally something resembling a plan.

Ron was good with plans, plans were like chess, they were methodical and something good always came out of it win or lose.

But of course as was many things in Ron Weasley's life, this was not the case.

They were rumbled clearly. Calla had, had barely enough time to scrawl a note to her Dad and sent a brown school owl flying towards the Ministry (or what she supposed was the Ministry) and then she was back in the common room.

She could tell that something terrible had happened. Hermione was white, Ron was sat with his hands pulling at his red hair and Harry had a look on his face that told her that he was about to do something very brave, and exceptionally stupid.

"What happened?" she asked sitting down.

"Professor Snape caught me outside the staff room and I made up an excuse of waiting for Professor Flitwick and then I ran"

"And Harry and I were outside the room where Fluffy is but McGonagall came along and made it pretty clear that if she caught us there again it would be another fifty points each. So all in all were sunk"

"No were not" Harry said finally.

"I'm going to get the stone"

Calla put her head in hands as he began to talk and wondered if this was what Aunt Lily felt like every time Uncle James did something stupid.

By the time he had finished telling them all what would happen if Voldemort came back (and Calla tuned him out because she knew what would happen if he came back—her mother still cried on mother's day thinking of the grandma that Calla would never get to meet) Hermione had gone very white and Ron was pale too. Harry turned to her his face desperate.

"Cal come on, you know what's going to happen if he gets back. Tell them you understand"

"I do" Calla said through white lips and slightly gritted teeth. There was a pause where she sat there and tried to find that courage her Dad and her Mum had had when they had been running from Death Eaters and making their stand against darkness, now it was her turn. She was the daughter of Sirius Black and this might be only time she would ever get to prove that she was enough to her father when she had never felt like it and she had to stand up against evil. She had to stand against Voldemort. And if she lived then she knew that she would continue to keep fighting against him.

"We could use the map" Hermione said sitting up.

"What" Harry said looking bewildered. "Your not coming"

"Of course we are" Hermione snapped waspishly.

"You don't really think your that good do you?" Calla said scorn in her voice.

Harry grinned.

That night they were all ready. They had eaten, and Hermione had studied her notes and Harry had the map, Calla was pulling on her boots over her jeans and her jumper, Ron and Harry were the same and Hermione was in a skirt and tights. They had left Neville on the floor and that didn't feel like a good omen. But they had to keep going. This was bigger than them. This was bigger than all of them.

And just like that they were at the trapdoor and all Calla Black, Harry Potter, Hermione Granger and Ron Weasley could see was darkness.

And then they jumped.

It had been a long day and Sirius Black had been on his way to the floo network with James when the green fire erupted in the middle of the office and Professor Dumbledore came out looking somewhat worried. He turned to look at his best friend, James shrugged and Sirius could already tell that today was going to be one of those days. All he wanted to do was go home and snuggle with Marlene in the safety of his house, Merlin when had he become that person?

"Ah Sirius, James I was wondering if I could have a word, I received an owl from the minister to come immediately but he has no idea about what's going on and I have a feeling that the stone might be compromised"

James and Sirius exchanged looks, they had been expecting this since that Quidditch match when they had been told about the stone. Dumbledore had not said who he suspected involved but they both knew who whoever it was, was working for.

"We'll come to Hogwarts and do a check with you just as soon as we've alerted Kingsley" James said gesturing to his desk.

Just then there was a tap at the window and Sirius saw one of the interdepartmental memos with a letter it had probably took off an owl. He took it and saw the scrawled writing of his daughter. He ripped open the letter and the dread that rushed through him at the words sent him nearly rocketing to his knees in terror.

Wordlessly he turned to James letter outstretched. James took it and his face became grim.

Calla had not said much, but she had said enough.

Dad,

We know someone is after the Philosopher's Stone. Dumbledore is not here and therefore we are probably going to go and stop whoever is stealing it tonight ourselves, I don't know much but Harry's got a look in his eye that I don't like. We don't want Voldemort back. If you can get here hurry, if not we'll try and do our best and make you proud.

Love,

Calla.

Fuck.

And yeah that's a cliffhanger to end on isn't it?.

I hope you all enjoy this one, and I will endeavour to update sooner rather than later.

Next Chapter-Harry, Hermione, Calla and Ron fight their way through the series of challenges laid out before them in an attempt to stop Snape from stealing the Philosopher's Stone.
