A/N: Hey sorry for a wait. Here's a chapter to explain everything to you. It's called An Explanation because I'm explaining it to you.

Disclaimer: I don't own Harry Potter or any of J.K.Rowling's characters. I wish I had made the idea up but no. Oh well, ON WITH THE STORY!

An Explanation

Wow. I can't believe this. I'm actually on the Knight Bus riding to Hogsmade and then to Hogwarts! This is so exciting! And then I'm going to meet the REAL Albus Dumbledore! The only thing is, I'm getting really sick from this bus. "Ugh. Does it get any bumpier?" Andrea watched out the window at the passing Muggle cars and houses that flashed before her eyes in a blur.

"I'm sorry to inform you dear but it does," A kind woman answered from a post at the head of the bus. "Notice we have paper bags at the side of every bed. The worst time is- Ernie, what do the Muggles call that time again?"

"Hour to rush I think." A young man driving the bus answered as we squeezed through a narrow ally.

"You mean rush hour?" Andrea turned and sat down on one of the beds. Sirius came up to her and said, "Sick? Yea it happens to all of us on our first ride. You'll get used to it. I remember last year when James and Lily went home for Christmas-"

"Aw Siri, don't tell her that story." James sat on the other side of Andrea and pleaded to Sirius. Andrea took a breath and noticed a cinnamon scent to James. No wonder Lily chose him. He's actually kinda cute. Wait, I can't do this. He's Lily's man.

Sirius looked at James with a glare that obviously said, 'What are you crazy?' After a second of glaring, Sirius began the story, "So when they went home for Christmas, it was their first time on the Knight Bus, Lily was all upset cuz they were the only ones going home from Gryffindor and Lily didn't know much other people. So the Knight Bus was tossing and- whoa! Yea, like that, and James was sitting with a group of girls, including Lily because a girl from Ravenclaw invited her and James over, and all of a sudden, James threw up all over Lily!!! Ha ha ha ha ha ha ha ha ha." Sirius rolled around on the edge of the bed clutching his stomach from laughing so hard.

"Lily sent me a letter telling me all of this and said, 'And you know what else? Those girls weren't even disgusted at him! They all just started fawning all over him and asking if he was okay. And you know what else??? THAT WAS MY FAVORITE SHIRT! NOW IT STINKS LIKE JAMES' BARF!!!!!! Help me! (' She sounded upset so I resent the letter to her best friend close to her and asked her to comfort her." Remus gave a slight smile as if to join in Sirius' outrageous laughing fit, yet being respectful to Lily. Andrea looked over at James and saw he was blushing. She could help but smile ever so slightly.

"And you wanna know the worst part? Lily's still mad at me." James looked down at the floor when Andrea spoke up. Sirius paused his laughter for a couple seconds.

"It's not as bad as you think. I went to a birthday party once and they gave me a spoiled piece of cake. Since I was the birthday girl's best friend, I was sitting right next to her, and I threw up all over her." Now it was Andrea's turn to blush. James looked slightly happier about his accident and patted her on the back.

"Are we there yet?" Sirius complained. "I'm starving."

"You're always hungry." Remus gave him a playful punch on his shoulder.

"It'll be a few, kids. We have to travel to Paris in a couple. This couple wants a ride to the Leaky Cauldron. But we have to go to the Leaky Cauldron first to drop off sickly Mrs. Wincher. I'd say, about 30 minutes." Ernie said looking back over his shoulder. He almost hit a street lamp but it jumped out of his way.

"Awww man!" Sirius looked bored so he and James exchanged a glance and made their way over to where Peter was sleeping. They each silently counted to three and-

"BOO!" Peter woke up with a jump and started cussing at James and Sirius. Andrea smiled and turned to Remus.

"So how long have you known these goofballs?"

"Hey we're not goofballs."

"Shut up Peter. If she says we are, then we are." James smiled his trademark grin at Andrea and Sirius shook his head while rolling his eyes.

"Well, I've known Peter since last year, 'member that guys? And James and Sirius, actually last year as well! I met them at Diagon Ally in front of the broom shop. Those two I swear. Even when they were out of school they created disasters." Remus looked over at the two boys setting up what looked like a foghorn at the back of the bus. Remus saw Andrea looking confused and explained, "Alarming Ear Horns. When a person lies down and closes their eyes, they hear a- I don't know how to explain it, it sounds like when the tea is ready in the kettle, and well that noise sounds in their ear for a few seconds so they can't get to sleep. All in good fun though. There was an Awkward silence as The two watched Sirius and James set up the prank.

"So how do you know all of our names? I don't get it. How are we famous?"

At first Andrea didn't know what to say. Oh god. He asked the question. Should I tell him? He might be of good use. No better not. "Ask me no questions and I'll tell you no lies. Sorry Remus."

After what seemed a lifetime, the 5 students got off the bus and into Hogsmade. Andrea wanted to explore and see all the things she had heard about (and seen) in the Harry Potter books (and movies), however the Marauders ushered her on. They climbed up the long road to the castle, (Sirius complaining, "It's much longer than it seems riding in the carriages.") and the Marauders showed Andrea up to Dumbledore's office.

"Come in please!" Came Dumbledore's cheery voice after Andrea knocked on the door. "Ahh. Andrea Larson. I've been expecting you. But of what, I'm not sure." Andrea was puzzled by this expression and gave the professor a puzzling look. "I'm sorry. What did you want to see me for?"

"Oh. Well, it's kinda hard to explain professor. Here goes: I know about the future. Now I'm not psychic or anything but, before James and gang came to my house, I already knew about the wizarding world." Andrea paused but when Dumbledore said nothing, she had no choice but to continue. "This is how I knew about it." She handed the set of Harry Potter books and the 3 movies that she ordered fast delivery. "These are the famous Harry Potter books. The main character is Harry Potter, who is James and Lily Potter's, son. In the third book, Remus Lupin teaches here, at Hogwarts, and explains to Harry what his father is like. In the fifth book, Harry looks into Snape's, that is to say he's a Potions teacher here and he was teaching Harry Oculmency, Pensive and Harry finds out how his father felt about Snape. Want more proof?" Dumbledore look slightly puzzled by all the rush of information, however got back his calmed expression quickly.

"Wow. That's- wow. This is the first time I'm speechless! No wait, so what you're telling me is that you know about James Potter and Lily Evan's future?" Andrea nodded her head. "And they are destined to be man and wife and have a son?" Andrea once again nodded her head. Andrea could tell Dumbledore was trying very hard to surpress a laugh"Would you mind if I read these?"

"No go right ahead." After a second of awkward silence, Andrea spoke again, "Um Professor Dumbledore? Can I ask you a question?"

"Sure go right ahead."

"Why did you want me to attend Hogwarts? I mean, I'm pretty sure that I didn't do any magic."

"Well, Andrea, do you remember when you were six? That time at the zoo? You thought it was, how you said, 'like a tyrant' to tie up balloons and make people pay for them?" Andrea blushed. "Remember how they somehow were cut although the manager of that cart was away on a bathroom break and scissors weren't allowed in the zoo? That was magic."

"Yea, back then I thought the balloons were like animals."

"And remember when you were nine? How the wall magically disappeared when you thought it was closing in on your sister? That was magic."

"My mom got so freaked out. The wall had her favorite painting on it."

"And remember when you were getting attacked by that hornet? You had to run around your house about six times?"

"Actually it was seven times. Was that me who made the hornet blow up?"

"Not to burst your bubble but that was me. I didn't want my new student to get hurt now." Dumbledore smiled at his own joke. There was another minute of silence before Andrea spoke again.

"And I have another question. Should I tell the gang about their future? Or should I try my best to make it happen?"

"I believe you should try your best to make it happen. Otherwise, it may not turn out the way this author had planned it to."

"Wait, why are we going to make the future happen according to J. K. Rowling? I mean she doesn't know about the magical world does she?"

"I believe I can only give you a satisfying answer when I have finished these books and the movies. Now I'm sure that one of the boys will be your escort to Professor McGonagall's office. She will accompany you to Diagon Ally and you will get, well I'm sure you know. And after that, I will assign you a student to teach you the basics of magic that you have missed last year."

"Ooooo can it be Lily Pot- I mean Evans? Oh my god, J. K. Rowling said she was Head Girl in her last year and she's a top student. Or will be." Andrea couldn't help but smile at her own statement. At that moment there was a knock on the door. "Good thing we were done."

"Come in James. I'm guessing you were the one kind enough to escort Ms. Larson to Professor McGonagall's office then?" James nodded his head in agreement. "Great. Ms. Larson it was a pleasure talking to you. James, be good."

"So what did he want?" James said once they were out of Dumbledore's office.

"Oh I actually needed to talk to him." Nosy little boy isn't he?

"So, why did you need to talk to him?"

"James! I don't think it's any of your business!"

"Oh sorry. I was just trying to make conversation. Please don't be mad at me." James made a puppy-dog face at Andrea.

"James I could never be mad at you okay?" What happened next took Andrea by surprise. James leaned in and lightly kissed Andrea. She quickly pushed James away. "James. I can't."

"Why not?"

"I just can't. There are a few reasons. Some of them you can't know. I'm sorry. I really like you and all but I can't go against her." Shit I said too much. I hope he doesn't notice.

"Okay. I'm sorry. Can we still be friends?"

"Of course. But this never happened."

"Got it. Here take this passageway. It's a shortcut."

"And you know this, how?"

"Look, I know you've got some secrets to hide, and so do I. 'Ask me no questions and I'll tell you no lies.'" James mimicked Andrea and led her to McGonagall's office. Once inside the classroom he left her giving her a small wave and left for the long walk back down to Hogsmade for the Knight Bus. Andrea knocked on the door and was answered by McGonagall's voice.

"Come in dear." Andrea stepped inside the door and opened her eyes in shock.
