DISCLAIMER: I do not own either Harry Potter or Doctor Who.

The Doctor finally finished his book, Before Tomorrowland- he kept being rudely disrupted from his reading by either Amy or Sirius. He thought Sirius would have been as much as absorbed in the Harry Potter series as Amy. Sirius kept pausing from his reading by blurting out a question about either the TARDIS, if the Doctor had any theories how he came to be in the TARDIS, who the Doctor really is, and many, many more questions that had nothing to do with the Harry Potter universe.

There was this one time that the Doctor was at the climax of his book when he realized with a start that Sirius was just trudgingly along to Harry Potter and The Philosopher's Stone. Sirius would look up at him occasionally while he was trying to read.

Finally the Doctor had gotten annoyed and asked, "What is it?"

"You said you were not a wizard and the closest you were was a group of Muggles."

"Yes." said the Doctor eyeing Sirius warily.

"Well, if you are not a wizard, how is the TARDIS possible? The muggles do not have that sort of technology. I remember them shooting a rocket to the moon when I was a kid. A rocket is different from a time machine. Wizards, or the Ministry of Magic, have Time-Turners, which have limited time travel capabilities that only allows you to travel back in time for a few hours. What you have is a...a spaceship that can travel back in time! You only wanted me to read these books before I request that you send me to 1979, not because you are incapable of sending me to that time. You are not a Muggle, what are you?" asked Sirius as he was shaking his head.

"I'm a Time Lord. The last of the Time Lords. I've come from a planet called Gallifrey. Basically Time Lords were keepers of time; we kept watch over time making sure paradoxes were not created. Usually, we were a bunch of pacifists.

The TARDIS is a time machine. The TARDIS is actually alive, she was grown and she had once came to me in humanoid form." The Doctor smiled, "She once told me she took me where I needed to go. She may have very well set this whole thing up. I wish I could talk to her again and ask her what her plan is. Oh, she kidnapped me and we never stopped running ever since." The Doctor expression turned from a jovial expression to a lecturer mode, "If you lived as long as we do, you would get bored and want to see the universe. So you would find means that meet your ends. Quite a few Time Lords have TARDISes, is the plural of TARDIS is TARDIS or TARDISes? I never really thought of it before, well the ones who get bored very easily has them, to ensure that no paradoxes are created because, as I've said earlier, we are peacekeepers of the Universe. Observers of the Universe; we do not meddle in time."

"You're an alien?!" Sirius eyes widened, he had a concern expression when the Doctor acknowledged that he's been kidnapped, and he smiled, "I actually thought everything alien could be pinned down to wizards or anything magical. I mean, Mooncalves are the culprits behind crop circles. You learn something new everyday."

"Why are you not as interested in the Harry Potter series? The series is about your godson. I expected you to be absorbed, reading those series and that this would be the second time, at least, reading Harry Potter and The Philosopher's Stone, not the first time."

Sirius looked ruefully at the Doctor, "I just don't like them." In her little area, Amy looked up, sharply, from both Fantastic Beasts &Where To Find Them by Newt Scamander and Quidditch Through The Ages by Kennilworthy Whisp. Ever since she realized that the Wizarding World is real, she has been reading those two books nonstop. Rory tried to divert her attention by asking her to recommend one of them; Amy suggested that he reads The Tales of the Beedle Bard and resumed reading the other two books.

"You don't like them! Why ever not?" Amy looked confronted.

"For me, the Wizarding World is nothing new. I went to Hogwarts; I grew up knowing that I was a wizard and was destined to go to Hogwarts. I don't like this book. I hope the rest of the series are not like this one."

"That book," Amy swelled with indignation, "is what started it all! It paved the way to the Wizarding World and taught kids lots of lessons in between. If Harry didn't rescue the Stone then Lord Voldemort-"

"Would not be affected either way. I skipped to the end of the book," earning him a hurt look from Amy, "Dumbledore awards Harry and his friends points for what? Going through an obstacle course? Dumbledore even states that the Stone was never in danger from Voldemort until Harry comes. So why does he award Harry and his friends when he should be giving all of them weeks of detention? If the Marauders, my group of friends, engaged in an obstacle course by breaking every school rule in existence, we would be very lucky to get detentions if not suspensed! I know it is suprising coming from me, but Dumbledore was encouraging Harry to be foolish! He is allowing Harry to develop this huge hero complex and not disciplining Harry to prevent Harry from getting killed. Merlin! I'm starting to sound like Molly.

"The main reason I don't like this book is that Harry was supposed to have grown up already knowing he was a wizard. He-he should already know about his parents and their friends. By the time he entered Hogwarts, Harry should have already know about me. He should at the very least despised me but he doesn't ask any questions! Once he discovers that he is a wizard and he finds someone who could possibly answer his questions, but he does not ask Hagrid anything about his parents. What houses are they sorted in? What were their favortite classes? Was his parents good students? What were their best friends? What did they aspire to be when they got out of Hogwarts? Harry does not ask anyone about his parents. Hermione Granger has a better reaction to the Wizarding World than Harry. She reads and tells him if it was her she would be reading all about the First Wizarding War and how she fit in to it!

"One more thing, Harry is being described not liking his appearance. The messy black hair-He got from James. He is a young James Potter but with Lily's eyes. I would think he would be standing in front of the mirror looking at his reflection wondering from what parent he inherited his looks from! It appears that he likes his scar; the SCAR his PARENTS' MURDERER gave HIM. He thinks it came from the car wreck that supposedly claimed his parents' lives. Don't you think that scar would be his least favorite attribute because he received it when his parents died?

"I can't help but to wonder what James and Lily would think if they had the opportunity to read these books." huffed Sirius.

The Doctor looked over to Amy who was wearing an odd look. He remembered in a different timeline that Amy had grown up without her parents. There were innate things about her to suggest that there was something missing by her knowing to carve a smiley face on his apple and, yet, did not know where her parents were. He even asked her, did she wonder why she was living in a big house, all alone- with no memories of her parents. Rory was the key to the mystery when he got sucked into a crack, a similar one that was in her house, and Amy had forgotten about her fiance, but she knew there was something missing, as well, because she would be crying with no apparent reason.

"Sirius, did you know everything about your parents? Like how they met, what did they want to do for a living, what they were like in school when you were eleven years old?" asked Amy.

"Of course, I'm a pureblood, I knew that as well as my family's genealogy! I grew up knowing that I was expected to be a Slytherin." Sirius gave a wolfish smile, "When they found out that I was sorted into Gryffindor, they came to Hogwarts just to have me re-Sorted. I don't know how many times I tried that hat on so it would answer differently. It barely touched my head when it screamed "GRYFFINDOR" for the last time. My parents tried oh, so ever hard for me to be transferred to Slytherin because, as they said," Sirius Black put on a shrill voice, "House ties are important. Those connections, you make when your younger, will be with you for all time. It is important to be sorted into Slytherin because Slytherin uphelds the Blacks' values." A horrbile look graced Sirius features.

"True, but Harry Potter never heard about the Wizarding World before! So, maybe he had so many questions about the Wizarding World that he did not have time to ask any about his parents. I don't recall you asking about Harry or anyone else when you suddenly popped in to the TARDIS! You were busy, like Harry, trying to figure out what is going on." said Amy in a triumphant voice.

The Doctor who was struggling to get to his book and was tempted to tell Amy that he held the same concerns that Sirius had about Harry. Maybe it was the age difference. Amy started reading Harry Potter when she was at least a pre-teen or as an eight year old kid. Kids would not factor in the flaws that the Harry Potter series has; they would be excited, like Harry and friends, about Gryffindor miracously winning the House Cup in Harry's first year. Children would not be questioning that particular plot twist. Teenagers and adults might question it because they would think, like Sirius, that Harry would have earned infinite amount of detentions. Kids, as well, would think it is cool to have a lightning bolt scar but an adult would actually think it was awful that a kid likes a scar that was given to him as a momento of his parents' deaths. There were various other things that a child may view differently than an adult would when it came to the Harry Potter series. Amy grew up with those series so re-reading them, she probably wouldn't see the discrepancies like an adult who was reading the series for the first time.

"Have you gotten to the Mirror of Erised chapter, yet?" asked Amy.

"No, I've just been reading the chapter where Harry has been given James' invisibility cloak."

"Well, when you get to Mirror of Erised's chapter then you will see that Harry has been yearning for his parents." Amy said thinking this would Sirius would become endear to the series.

It really didn't happen that way. When neither had their nose buried in their respective books, Amy and Sirius was constantly arguing.

"He just looks at their appearances; he doesn't bother asking Dumbledore anything about his parents when Dumbledore tells him not to be looking at the mirror all of the time!" Thankfully just getting Amy rolling her eyes.

The Doctor was back to reading his book when Sirius let out this mad cackle. "Seriously! Dumbledore tells Harry that the reason why Snape holds a grudge against him is because James saved Snape's life? He is only having Harry harboring contempt for Snape. I'll be the first to say that Snape is an oddball but not telling Harry why Snape seems to hate him will only cause a further rift. Dumbledore should have admitted that I endangered Snape's life and James had to come and rescue him! Oh, wait! I only exist in the first chapter of this book because no one decides to be truthful to Harry and tell him that he has a godfather! Sure, a godfather locked in Azkaban for a crime that others believed him to have done!"

"Snape didn't want Dumbledore to divulge to Harry about that particular incident where you set Lupin loose on Snape. Maybe it hurts to reveal that you knew a person who betrayed their best friends to Voldemort." said Amy.

"It hurts to reveal that a person betrayed their best friends to Voldemort?! It hurts being sent to Azkaban for a crime you didn't commit! FOR TWELVE YEARS! I actually expected Harry to hate my guts but it surprised me that his anger with me evaporated quickly. I now understand why; he's only heard of me in that school year. It hurts me to be reading about Ron Weasley's pet rat who happens to be missing a finger! What would Snape's and Harry's relationship be like if Harry learned the truth? Harry would understand that Snape harbors anger towards him and knows not to set him off. Maybe once in a while, Harry could say "I'm not my parents." I don't know how Snape would take to that. I know I have spent my life trying to prove that I am not my parent's son.

I wonder how Harry would be like if he had known everything that he needed to upon entering the Wizarding World. Knowing all the facts, so he can use his better judgement. We were trying to conceal the prophecy away from Harry-All that time Voldemort was trying to get him to the Ministry of Magic so Harry could get the prophecy about both of them. We were afraid that Voldemort could get into Harry's memories and be able to know about the prophecy. I might have been still with Harry if it was not for trying to hide the truth from Harry. I mean, if I told Harry about the prophecy it would have shocked him, but he would know not to be searching for it." Sirius barely read the second book and was having problems of how people treated Harry in regards of open disclosure.

"Dumbledore realized his mistake; he knew that he should have told Harry sooner about the prophecy but he did not know how Harry might take the news. If you are acting this way on book one, I hate to see how you are going to react to book three." Amy smiled mischievously.

The second book did not have as many outbursts from Sirius because he started realize that Harry was the type of kid that takes everything in stride.

He was angry at the Dursleys for imprisoning Harry for something he did not do: Dobby had magicked a pudding to fall on the ground. However, he expressed his gratitude toward the Weasleys for coming to Harry's rescue and being some type of a foster family for Harry Potter.

"The gateway to Hogwarts Express seals shut, what do you do? Why, you fly your parents car to school, of course! You have an owl that could be sent to one of your professors telling them what happen, but no you decide to fly instead. Publicity stunt? I didn't think Harry was the type." groused Sirius.

By this time, Amy had learned not to argue with Sirius. The Doctor had finally finished his book so he was going to make Amy swap books with him.

"Amy, you have been going back and forth between Quidditch Through The Ages and Fantastic Beasts & Where To Find Them, it is time for you to read something else. Why don't you read Before Tomorrowland? It is an exciting book about a secret society wanting to go public in attempts to make an utopian society. However, they are facing some opposition."

Amy had reluntantly allowed the Doctor to read Fantastic Beasts & Where To Find Them. She also handed Rory Quidditch Through The Ages. The Doctor was grateful that Amy did not act like Sirius and by not pointing out flaws in that book.

Fantastic Beasts & Where To Find Them was an interesting read but the Doctor was still living in Tomorrowland so he was not able to fully enjoy reading. The book was basically defining what are beasts and the Doctor had to agree with Ron and Harry that it was a tedious explanation at that. He liked some of the banter that would ensue between Harry and Ron in the margin of that book. The beasts themselves were listed alphabetical order and rated on how danger they are to humans.

Sirius was just sullenly reading and gave up commentary because Amy was no longer willing to argue with him anymore.

"May I have a piece of paper and something to write with?" Sirius asked.

"Why?" asked the Doctor suspiciously.

"You offered me a challenge, kind sir! I must complete your challenge. Don't you remember talking about sending notes to former selves?" Sirius smiling.

"Yes and I told you not to! Don't you understand the repercussions of time travel? There are Weeping Angels and Reapers that are more than happy to feed off of paradoxes. Reapers are temporal predators; if something is to go awry in the timeline, then the Reapers will remove the offending element. Which would be you, if you think trying to change the future is possible. Reapers are dragon-like with two wings, two claws, mouths on their chests, and a scythe-like tail. Then there are Weeping Angels, now that is something you don't want to mess with! They live off of time energy which you have created if you continue on your foolish plan! Basically Weeping Angels, concrete angels, usually send people back in time to feed off of their remaining time energy, what could have been! But, no! You will not need a Weeping Angel to send you back because you will be sending yourself back allowing it to feed off of your time energy. Do not, I repeat, do not write to yourself to alter your future!" The Doctor said furiously.

"You've talked about travelling in time. So, haven't there been loads of time when you wanted to go back and correct anything? Isn't there a particular memory you wish you could change?" asked Sirius.

"Of course. I've also had many companions that wanted to change the past but realized they couldn't. These are Weeping Angels you are messing around with though! I've met a bloke where he was sent back in time following a list, made by the Angels, trying to prevent an accident, that claimed his wife's life, from occuring. He was unable to prevent it from occuring. Of all the people in the world, the Angels had chose to mess with Mark Whitaker, making him relived his wife's death. At the very least, he now knows that his wife did not die alone." The Doctor said thickly, "But what you are trying to do is to invite the Angels in!"

"Doctor, what about my parents? I have lived two timelines and haven't met with any repercussions! Why can't Sirius create two timelines and allow Harry to live with him or prevent Voldemort from ever finding Harry's parents?" asked Amy.

"Your parents were a special case, Amy." The Doctor looked so stressed out, "Time was collapsing on itself, allowing me to be able to pull off some miracles. It took you, remember, to bring me back to this Universe. If you hadn't remembered me, I would never been able to come to your wedding. Time travelling will always have consequences. It took me and the Pandorica Box to be able to reboot the Universe to attempt to re-seal all the cracks in the Universe that the TARDIS somehow created. Time is not collapsing on itself now. There is nothing that I can think of to be able to pull off and change your past. The Harry Potter Universe became a fixed point with the installments of the book series."

"So, this writer, can she perform the Imperious Curse by writing down what happens in her books and I still have to follow it?" The Doctor nodded "That's NOT FAIR!" roared Sirius.

"I COULD REALLY USE A DO-OVER! AN ACQUAINTANCE MURDER MY BEST FRIENDS! MY GODSON IS TREATED LIKE RUBBISH! I'VE BEEN SENTENCED TO AZKABAN FOR LIFE, FOR A CRIME I DIDN'T DO! AND YOU ARE TELLING ME THAT I CAN'T GO BACK AND CHANGE ONE THING BECAUSE AN AUTHOR HAD SEEN FIT TO WRITE ABOUT MY GODSON'S LIFE!?" screamed Sirius, "I HAVE THE MEANS TO FIX MY LIFE AND MY GODSON'S BUT I CAN'T BECAUSE OF SOME STUPID RULE!"

"I'm sorry" said the Doctor, "I really wish I could help you but I don't see how, without inviting the angels-"

"What is the worse the angels can do?" asked Sirius.

"They'll feed off of your time energy. Inviting them may only cause them to send you back further in time. You may be in the time of the founders, the founders of Hogwarts, and you could be anywhere in time and space. If you are really unlucky, then a Reaper may come. A Reaper would take you out of time basically kill you to prevent paradox from ever occuring again. Again, I'm sorry, but I don't want to instigate anything to come here." said the Doctor.

"So, the worse to happen to me is that I get killed? Or some angel take me further back in time so I can live my days out before ever getting to see James, Lily, Remus, or Harry again? I have nothing to lose then. I'm already living on borrowed time; I went through the Veil in the Department of Mysteries. Your not suppose to do that!" exclaimed Sirius.

"Even if you somehow manage to go back and change time, your current self will no longer exist. Making it impossible for you to successfully change your own timeline. Thus not enabling you to be at this moment wanting to change time. A paradox."

"Again, I have nothing to lose. I don't want to ever be this version of me. Aren't there things you are willing to fight for? How's this, I write myself a list of all the things I want to change, and have that bloke over there re-write it for me? We can make it that he wrote the list in the first place. Maybe, just maybe, he had an incredible urge to write a list because of a dream!" Sirius was grinning madly.

"What? Are you going to put me under the Imperious Curse?" asked Rory as he was squirming rather wishing to be somewhere else.

"Of course not. But if I present you a list, will you copy it down for me?" asked Sirius looking as mad as ever.

"Sure, but isn't that going to cause the same problem mentioned earlier? If this works out, who is going to write me a list prompting me to copy it and hand it over to you?" asked Rory.

"Let's not worry about it." a thoroughly confused Sirius said. "I mean, if this works out I'll never need this opportunity for a list to be written out. It'll be like I've never been here."

All four people in the TARDIS were really confused now, even the Doctor which says a lot. Rory agreed to copy the list, Amy found paper and pencil to give to Sirius, Sirius resumed reading, and the Doctor looked disapprovingly on.

It took a long time for the Doctor to resume reading because he couldn't help to think that Sirius Black would run off in any opportunity he gets to change his past. He was trying to work it out how Sirius would be able to have this considerable feat. He felt that it may possibly happen if it was an outside source that change Sirius's life. Sirius would be too close to the problem. Of course, he was not going to share his outlook to Sirius. He still thought this was wrong. He didn't know if he was wrong or not but he felt if Sirius succeeds then he would be taking something away from literature.

The Doctor was bustling around the kitchen so everyone could have something to eat for a late lunch. He used to have pills on hand that were nutritious but he had so many complaints from his companions that he would now has human food. He created a kitchen specifically for his companions but he had an interesting palate and enjoyed human food. He had seen greats like Julia Childs and other chefs but he, himself, was not a chef. He still felt that fish sticks and custards made an appetizing meal. Then he heard a yell causing him to find his way, out of the labryinth, back to console.

"WHAT! THOSE WEASLEY TWINS HAD THE MAP ALL THIS TIME!...NINE YEARS, NINE YEARS! I COULD HAVE BEEN OUT OF AZKABAN WHEN HARRY WAS NINE YEARS OLD! DIDN'T THEY FIND IT ODD THAT THEIR BROTHER, PERCY WEASLEY, WAS CONTINUOUSLY HANGING AROUND PETER PETTIGREW, A MURDERED VICTIM?!" Sirius thundered.

The Doctor was grabbing his chest and looking around. Rory was looking very timid but Amy had a smile playing on her lips. Sirius Black had found one of the plot holes in the Harry Potter series.

"Why did they allow me to rot all this time instead of alerting a teacher that their brothers were sleeping with a murdered victim?"

"Maybe they were too concern about pranking that they were not paying that much attention to their brothers?" smirked Amy.

"They are pranksters, wouldn't you think that they would have pranked their own brothers? Using the map, to ensure that the appropriate victim was coming? Those twins have a lot of explaining to do, as to why they allowed me to rot all those years in Azkaban in favor of holding on to the map." Sirius was looking livid.

"I also don't understand how a rat could have been allowed at Hogwarts. If I remember correctly, Hogwart students are only allowed to bring either a cat, toad, or owl. Why didn't Snape use that rat for potion ingredients?" at that moment Amy was laughing outright earning her a disapproving glare from Sirius.

Sirius had scrawled something on the piece of paper and then resumed reading about Harry using the map to go to Hogsmeade. The Doctor waited because Amy told him so; she knew that there was going to be another outburst from Sirius and she was right.

He had been complaining about Harry being susceptible to dementors and they had no business being anywhere that school despite having a criminal on the loose. "Harry had to hear that his father's best friend murdered his parents and on the run looking for him while being under a table at The Three Broomsticks. AND MCGONAGALL, HAGRID, ROSMERTA, FLITWICK, AND THE BLOODY MINISTER ALL THE HAD THE NERVE TO CRY OVER THAT BLOODY TRAITOR, PETTIGREW!" That should have never happened! Harry should already have known about me and my so-called deception before he came to Hogwarts. If the Weasley twins alerted any of the teachers, I bet my name would have been cleared and I would have custody over Harry like his parents wanted me to have!" Sirius grimaced.

"Dumbledore would not have allowed Harry to be separated from his Aunt." Amy said quitely.

"WHAT? Why is that? Why would he go against the wish of James and Lily to have Harry raised in that...MESSED UP ENVIRONMENT."

"You remembered in the first book that Dumbledore told Harry that Voldemort could not touch Harry because of hs mother's protection, right? Well, Dumbledore used her protection to set up blood wards. Harry had to go back to the Dursleys after the year is finished to strengthen his protection against Voldemort. Harry always had to treat the Dursleys' house as home in order for the protection to work."

"Seriously? Dumbledore thinks that wards are going to have more protection than a fully trained wizard? If YOU remember correctly, all the books I have read tells how Harry sees Hogwarts as his home and he really does not want to go back to the Dursleys. Why do you think he jumped at the opportunity to come with me and live elsewhere? This IS coming from the man who had seen fit to deposit my godson on someone's doorstep on the night of November first, which I don't have to remind you, it gets very chilly in England, if not rainy during that time of the year. Harry could have died from pneumonia! Also, Harry already knew how to walk by that time; I had received a picture, from Lily, of Harry riding a toy broomstick that I gave him for his birthday that year. He was able to hang on to that broom. How come Dumbledore did not think that Harry would get up and wonder off after he placed Harry on that doorstep?" Sirius questioned, "4 Privet Drive, Little Whining, Surrey, England!" Sirius's face split in a manic grin. "He was left there on November first! If I had known that Dumbledore was going to let Harry stay on that doorstep, waiting for Petunia Dursley to answer the door, then I would have steal away with Harry."

"Oh, no , you don't! Don't you dare kidnap your godson!"The Doctor stared frowningly at Sirius.

"Why ever not? He would be a lot safer in my custody than he would ever be with the Dursleys. Also, if you do not remember correctly, Voldemort used Harry's blood in the Resurrection Ritual. What stops him from getting Harry in the summer of Harry's fifth year when he, Voldemort, has Lily's blood coursing in his veins?

I'll be wanted for kidnapping, but I won't be staying in the country to give Voldemort an opportunity to get his body by Harry. Don't you see? If I am to interact in my own past- it has to be my present self, the one who reads all the books and knows what will happen if Harry goes to Hogwarts. Harry must not go to Hogwarts!" Sirius mimicking Dobby.

The Doctor did not know how to make heads or tails out of this. It would change the books or destroy them because for Sirius, acting as his present self, kidnapping a baby Harry, while his past self is locked away would never be his present self!

"Don't you realize that Harry saved you from the dementors, and more importantly the dementor's kiss, while he was in Hogwarts? That you have encountered everything you have due to Harry being at Hogwarts! You would not wind up in my ship trying to change the course of your history if you kidnapped him. That timeline will not exist; you will more than likely encounter an Weeping Angel. Or your current self could actually fade away because something, you, in your past intervened and prevented you from being the person you are today. Pick what you want to eat and let's go to the kitchen." The Doctor wearily said. He was tired arguing with the most stubborn man in the universe besides himself. He was stubborn himself but he knew when time had him beat.

He knew he was giving Sirius a sensory overload by taking them to the kitchen. They had passed a room that was nothing but the best day. The room was covered in green grass and the sun was always shining. When no one was inside, a type of mist will be sprayed watering the trees and the grass. Maybe they should read in there at some point.

They all gathered around the kitchen table as the Doctor served fish sandwiches and chips. He had one rule with Sirius around-no discussing how they can change the future. Both Sirius and Amy were poring over their respective books. He was glad that Amy was starting to enjoy Before Tomorrowland. This might give her a chance to step away from the Harry Potter Universe to realize she was having an unhealthy obsession. Apparently Rory and him were the only normal ones in the TARDIS. He did not want to engage in any conversation in case Sirius starts figuring out ways how he could change his past. Sirius was now irking Amy by reading the last chapter then the beginning page to each chapter and moving on when he found a chapter to be interesting. Then he would go back to the lesser chapters to finish. The Doctor figured that Sirius was reading Harry Potter and The Azkaban Prisoner must have felt that he was entering familiar territory with that book.

"Aha! What came before the dragon or the egg? You see, Harry was able to rescued me from the dementors because of time travel! Who came first then, the Harry with me at the Shrieking Shack or the Harry who drove away the dementors? As you told me one could not work without the other but who came first? You have to have the Expecto Patronum!Harry," Sirius may have read Amy's fanfiction, "to drive away the dementors for us to have survived but how did he survive without him be there in the first place. It is like their daughter," Sirius gestered towards Amy and Rory, "she needs to live in order to bring her parent together, but how did her parents came together without her? What does the original timelines look like in both Harry and their daughter's life?" Amy and Rory explained what happened to Melody Pond to Sirius when he was having a fit of laughter while the Doctor had stormed out. He originally thought how preposterous it all sounded but sympathized with Amy and Rory.

The Doctor just stared at Sirius. How is possible that Sirius is able to think of that argument? Sirius was just...dumb, the Doctor couldn't find a better word, in Harry Potter and The Prisoner of Azkaban. Both he and Lupin should have realized that there was something wrong when a door can open and shut by itself. Later in the series, fans had discovered that there was a Disillusionment Charm to make a person nearly invisible making Sirius and Lupin look even more foolish to not realize they were not alone in the Shrieking Shack. Fans also later learned that people can transmit messages with their Patronuses and Lupin should have alerted Dumbledore about the situation in the Shrieking Shack. Even though Lupin would never send a message to Dumbledore alerting him to the situation because of his fear of disappointing Dumbledore by not telling him how Sirius and Pettigrew were Animagi and they hung around him during his transformations as a werewolf. Probably the dumbest moment in Harry Potter and The Prisoner of Azkaban was when they tied up Pettigrew while Pettigrew was in his human form and tying their two weakest, Remus the werewold and Ron who had a broken leg, to Pettigrew. Why didn't they stunned Pettigrew? Sirius Black and James Potter, the cleverest wizards of their age indeed. If they were the clever ones, then the Doctor would like to meet the rest of their class for chuckles and grins.

"Yes, Doctor. Sirius has made a brilliant point. What is the original timeline for all of us and River Song? What is the original timeline for Sirius and Harry? Is there a timeline where Harry barely makes it out in time so he feels the need to help himself out a bit so he time travels?" Amy smirked.

The Doctor was rubbing the bridge of his nose. "The reason why River was able to set you together despite not being born yet is because there had been an hiccup in time. A miracle occur or what have you, " he was becoming rather annoyed at having to repeat himself differently. The Doctor gave a viscious look at Sirius, "Your predictament was caused by an author. Are you sure this really happened? Also we are talking about time travel again. "

Sirius looked a little put out, "If the author somehow put us all under an Imperious Curse to make it work out, then maybe it really did happen. I don't know, because I was awaiting a Dementor's Kiss in Fitwick's office during the time Harry and Hermione rescued me. They didn't explained what happened. They handed Buckbeak over to me and told me to fly him!"

At that, everybody chose not to engage in further discussion. Rory only complained of getting a headache. They finished their meal and resumed reading their books. Sirius knew to keep his mouth shut because he was starting to grate on the Doctor's nerves.

A couple of days later, Amy had finished Before Tomorrowland so they swapped books allowing the Doctor to reread that book. After he was finished, he asked Rory to keep watch over Sirius and took Amy to the library. Rory did not look happy about this idea.

Once in the library he told Amy some of his concerns, "I don't know what to do with Sirius Black? Is he some book character that got out of the book and somehow can do magic in this Universe? Does he exist in this Universe? He supposed to have died! What am I suppose to do? Deposit him back to the Wizarding World of Great Britain and say, 'just kidding?'"

"How do you think he got in the TARDIS?"asked Amy.

"I had a companion who had materialized in my TARDIS. Her fiance was dosing her coffee with Huon particles for the Empress of the Racnoss. Those particles allowed her to materialized in the TARDIS. I'm glad she materialized," The Doctor had a cross expression,"I'm glad her fiance died."

Phrasing her words carefully, Amy asked, "How did she leave? You're not looking at keeping Sirius as a companion, are you?"

"No, I don't want to be looking over my shoulder constantly wondering if this is the day the universe is going to break apart when Sirius encounters either himself, James Potter, Pettigrew, Harry, or anyone that can change his actions that led him to my TARDIS. " The Doctor looked incredibly sad, "Something happened when I was in my tenth regeneration. My companion saved the universe but she can never know that or remember me. She would have been driven insane while her mind is burning up. I was so shaken up about it that I stopped liking endings. You'll never catch me reading the last page of a book or if I can help it the last chapter. I did not read the epilogue in Before Tomorrowland. How can you cope with the idea that your friend can never remember you or any of your adventures together? I erased all of her memories and sent her home with specific order to her family to never mention me or the TARDIS. "

Amy had her hand over mouth while her eyes grew round. "Does Sirius have any Huon particles in him?" She asked hoping to change the subject quickly.

"He should not have any as far as I can tell. What made him able to go in the TARDIS must have occurred when he went throught The Veil. Like I said the other day, if that was the case, then everyone would have gone through The Veil would be inside my TARDIS. I don't know how Sirius wound up in my TARDIS and I don't know what to do with him. I'm afraid that he'll encounter someone from his past or himself and end up getting himself killed because everyone knows at a certain point Sirius was at Azkaban and then he was an escaped convict."

Amy and the Doctor was looking for different books to read. He came across "The Crucible" by Arthur Miller and shuddered. That was the play he had Susan watched as well as Goodwife Rebeca Nurse. He was trying to convince both of them how the Salem Witch Trial played out in history. He was trying to show Rebecca Nurse that she mattered in history; her determination to keep her head while going to the gallows allowed for those who claimed she was a witch to start questioning it. Her death had a domino effect; people started to realize that no one as pious as Rebecca Nurse could ever be a witch but she had been persecuted as one. Yet, her death was necessary to put a stop to the Salem Witch Trial.

Here is he, all those years ago, now treating Sirius Black the same way he treated Rebecca Nurse. Telling him to face his death honorably so that thousands of Harry Potter fans can get the symbolism of Sirius' death. To have Harry and his readers to learn how to cope with the loss of a love one. He was having Sirius read the series instead of watching the movies. He blanched at the thought of Sirius watching the movies. If the books were loosely based off of Harry Potter's life, then he did not want Sirius Black see the amended version. After seeing "The Crucible" and visiting her old house, Rebecca Nurse held her head high and accepted her fate. The Doctor did not think Sirius Black would accept the limited time he had with his godson as well as knowing he was going to die before his best friends' betrayer had been brought to justice for being a Death Eater as well as murdering twelve Muggles. The Doctor never really feel that Pettigrew was ever brought to justice.

"Did you ever heard of the question, "If you can eat dinner with any historical or ficitional character what would it be?" I would have picked Sirius Black because I felt like he truly had the short end of the stick in the Harry Potter series. I would have wanted to know how he would have raised Harry, what he would he have done if he knew about the Horcruxes, or what would he change in the Harry Potter series." Amy said, "It feels like my wish came true." The Doctor looked at her then he continued browsing the shelf before him. He couldn't think of a response. He always consider himself lucky to meet imporant as well as the average person during his travels.

"Amy, do you remember waiting for the Harry Potter books to come out? Some fans were trying to guess what was in the upcoming book. One of the popular theories was that somehow Ron and Dumbledore was one in the same and had gotten marooned in time. J.K. Rowling always mentioned that Ron's least favorite color was maroon. It was an enjoyable theory but so many consequences would have aroused if it were true. I just hope that somehow Sirius does not become an important character with a new identity because we travelled in the past.

I'm sorry, Amy. I did not bring Sirius here, but I thought it would be a good idea if you have met and discussed how it was like to be separated from your love ones. I thought both you and he would accept your fates. It makes it harder because he keeps arguing about how the past can change and I do, actually really do, want to be able to have you and Rory to raise your daughter as Sirius would be able to raise Harry Potter but everywhere I look it is not possible! I'm sorry that this had to happen and you must feel like you are losing her again with each theory Sirius proposes and I reject. I just wanted you to know how sorry I am."

The Doctor was about to pick up a copy of The Time Machine by H.G. Wells mainly because it was written by Hubert Wells, a member of the secret society, Plus Ultra, from the book Before Tomorrowland when he felt this horrible lurch and had to hold on to a bookshelf for support. He looked around and noticed that Amy had to grasp a shelf as well. It felt like they were free falling. The TARDIS was going to land.

The Doctor sprinted out of the library with Amy on his heels. They were winding through hallways and going through some rooms trying to get back to the console. Another jolt sent them crashing down onto the floor. The Doctor pulled himself up and proceeded to the console.

Rory was holding on for dear life to one of the scaffolds as the TARDIS plummets. Sirius, on the other hand, was deeply absorbed in reading Harry Potter and The Half-Blood Prince. He was sitting on the floor of the TARDIS and as the TARDIS jolted and plunges causing Sirius to be airborne. Sirius never bothered looking up as the Doctor marched over to the console. He knew that Sirius was the offending perpetrator by not acknowledging that the TARDIS was crashing. The Doctor was vainly trying to prevent the TARDIS from crashing; the TARDIS was heavier than Earth so whatever planet they landed on, they'll be sending it out of orbit. Amy had collapsed on the floor and Rory crawled towards her.

The TARDIS started feeling like it was drifting downward like a feather to the Doctor's surprise. Was this going to be another mystery like how Sirius came aboard the TARDIS? He was feeling like the TARDIS was bending over backward to destroy the laws of time and nature. He wondered if the TARDIS was trying to accommodate Sirius and change the story somehow. He knew that the TARDIS was like a horse by being able to feel the emotions of her occupants. Amy had been reading so much Harry Potter, that the TARDIS may very well invited Sirius in to help Amy cope with loss of not being able to raise her daughter. He was providing her distraction by making her think different theories on how Sirius came in the TARDIS and what was his mission. Yet, Sirius was not benefitting because he was still trying to think up ways to change his past instead of gaining acceptance from Amy.

The Doctor was able to land the TARDIS safely. He switched the scanner on, then hit it on it's side trying to make it work. The scanner showed that they were on an Earth-like planet. He realized they landed in Great Britain, specifically in Cokeworth.

He was trying to remember what was significant about Cokeworth when he said, "No one. Absolutely, no one is permitted to leave the TARDIS. I do not want any of you wondering off on your own. I repeat, absolutely no one is allowed to leave the TARDIS. Do you hear me, Sirius?"

"Yes." said Sirius while he continued reading not really processing what the Doctor said.

The Doctor shook his head. He was not going to bother telling them where they landed. The name Cokeworth was worrying him. That name was oddly familiar but he just can't place where. What happened specifically at Cokeworth in July 26, 1990?
