As you read this, you may or may not pick up on the fact that this is quite a lot like Doctor Who. Just throwing in a disclaimer that I'm not the BBC either.

One-
Assassinating the President.

June 4th, 1998.

Edinburgh, Scotland, UK.

I was sitting in a cafe in Edinburgh, drinking a cup of tea and drawing up plans for John F Kennedy's assassination (maybe I did, maybe I didn't) when a young man with glasses and a lightning bolt scar on his forehead walked in. He was mumbling angrily to himself as he sat at the table next to me and ordered a cup of coffee.

I leant over to him. "Excuse me, but could you tell me the date?" I asked quietly.

"Yeah, it's the fourth of June," he said, looking at me sceptically.

"I missed it again," I groaned. "Not far enough back!" He looked at me weirdly and took his coffee off the waitress. "Wibbly wobbly, time-y wimey, wibbly wobbly, time-y wimey!"

"What?" he asked, obviously wondering whether I was sane.

"Do I know you from somewhere?" I asked, looking at his face.

"Depends, why?"

"I don't know; you just seem really familiar."

"What are you working on there?" he asked, shuffling his chair over to get a closer look.

"Oh nothing, it's just work stuff."

"Looks like you're planning to kill someone," he said, one eyebrow raised. "Looks like you're planning to kill JFK, actually."

I opened my mouth and then closed it again, trying to come up with a clever lie. "I... work for... the... Government," I said awkwardly. He smiled at me as if to say 'yeah right' and we both burst out laughing.

"I'm Harry," he said holding out a hand. "Harry Potter."

"Keira Reid," I smiled, taking his hand and shaking it. "What brings you to this part of Britain, Harry Potter?"

"Come to visit a friend up in Aberdeen, actually. You?"

"Parents. They live here. So did I, up until I was about sixteen when I got fed up with them and moved down to London with my Aunt."

"I didn't think you could get rid of a Scottish accent so easily."

"You can't. This is a fake one. I really sound like this," I said, slipping into my Scottish accent. My watch started beeping and I groaned. "I've really got to go. It was great meeting you, Harry, but I've got to run. I've got a President to assassinate," I winked. I gathered my papers and pushed them into a pile then shoved them into a folder before running out the door. I ran around the corner and made sure no-one was watching before checking the co-ordinates in my watch and leaping back to 1963. Harry came running around the corner.

"Wait! You forgot your jacket!" he yelled, but I was well on my way through the time vortex backwards in time.

July 1st 1998.

London, England, UK.

3 months later.

I was walking along the street, head down, muttering to myself when I ran into a man. "Sorry," I said. "Wibbly wobbly, time-y wimey."

"Hang on," he said. "Keira?" I looked up into the eyes of the man.

"It's Harry, isn't it? Harry Potter. What day is it?"

"It's the first of July."

"Ooh! I didn't miss it!"

"Miss what?"

"Oh, nothing. Not important at the moment. I'll see you around, Harry." I rushed off and into a store where I bought a simple, elegant dress. I then went back in time to put my name on the guest list of a very important dinner party. I jumped forward and booked into a hotel for the evening, before getting ready for the party. I located the side entrance and ducked in, checking that no-one saw me. Once inside, I stuck mainly to the shadows, using the scanning feature on my watch to identify people.

"Hey! Keira!" called a man.

"Harry," I said, slightly surprised.

"Keira, these are my best friends Ron and Hermione. Guys, this is Keira. I met her in Edinburgh about a month ago."

"Three months," I said automatically.

"What?" Ron asked.

"Oh, nothing. Wibbly wobbly, time-y wimey."

"What?" the ginger asked again.

"She says that all the time," Harry interjected. "So, how did your assassination of the President go?"

"Oh, brilliant! No-one suspected it was me. Ooh, is he about to give a speech?" I said, pointing up at the host of the party.

"Yeah, that's Mr Henries. He must have invited you. I checked; you were on the list."

"Yeah, of course. Long day. Listen. I've got to go and... Do something... important," I said awkwardly and walked swiftly away. Harry turned to his best friends to see a look on Hermione's face that meant she was thinking very heard and very fast.

"What is it, Hermione?" asked Ron.

"Those words. 'Wibbly wobbly, time-y wimey. I've heard them somewhere before, I'm sure of it."

"Ladies and gentlemen!" called Mr Henries from the stage where several honourable people were sitting. "Everyone here has had the greatest pleasure of working with me in the past, and to reward you, I have set up this dinner party. Be warned, though, that the doors are locked and there is no way out. You will all die a very painful death, choking on gas. Good-bye, associates." He pulled on a gas mask, as did the people sitting on the stage.

"Or not," said Keira, coming up beside Mr Henries. He mumbled something behind the gas mask. "Sorry, didn't quite catch that."

He pulled the mask up. "What do you mean, child? You will die same as everyone else!"

"How to explain this to a simpleton like yourself. No poisonous gas is coming to kill us." I grinned insanely. "Not today, anyway," I added on the end.

"Yes it is!"

"No, I stopped it."

"How?" he demanded.

"Well," she started. "You see, I have an expansive knowledge of ventilation systems, such as the one you were trying to pour gas through. That, put together with the fact that I knew this was happening today, meant that I was able to switch the gas with simple air fresheners."

"How could you possibly know what I was going to do?"

"I'm very good."

"No, I'm very good."

"Oh, yes. In fact, I'd say you were brilliant, if I wasn't on the... planet." She pulled back his gas mask and placed it back on him. She waved and pressed a button on her watch. All of the gas-masked people fell over, unconscious.

"Oh my God, she killed them!" someone screamed.

"There's always one," I muttered. "Now, erm, Harry Potter! You are now in charge of this, because I've got to..." I looked at my wrist and wriggled my fingers. I jumped off the stage and ran out the front doors in the same manner as if I were being chased.

Harry groaned and walked up to the stage. "Alright, everyone, the Police have been called and everyone is going to have to make a statement. Once you've done so, you may leave." He looked around for me, but I was long gone into the future.

31st July, 1998.

London, England, UK.

3 days later.

I knocked on the door of 12 Grimmauld Place and waited for the door to be pulled open. Hurried footsteps came to the door.

"Oh, Luna! I was so worried! I thought you'd been mugged— Hang on, you're not Luna," said the ginger standing at the door.

"I need to see Harry Potter. Right now."

"Yeah, along with everyone else! How can you even see this house?"

"Just tell him Keira's here and he'll come!"

"No," she said defiantly.

"Listen," I started but she cut me off.

"No. Get lost. You weren't on the guest list. I didn't put you there."

"Check again. I'm under Reid-comma-Keira." She closed the door and ran to find the guest list. I pulled out a pen and scribbled on my arm: Guest list. I pulled down my sleeve just as the girl opened the door again. She flicked the list to 'R' and looked triumphant.

"You're not there!"

"Yes, I am. Look, right there. Reid-comma-Keira."

"How...?"

"Are you going to let me in?"

"No. I'm not. Because I don't know how you got on this list. I didn't put you there!"

"Look, Ginny, this is important. Your life could depend on this—."

"How do you know my name? It was Harry, wasn't it? I'm sure you both had a good laugh behind my back! How do you know him anyway? Are you like his girlfriend?"

"NO!" I shouted. "No, that could never happen."

"Just... do yourself a favour and get out of here."

"Ginerva Molly Weasley. It is imperative that I speak with Harry at this exact moment or the whole universe might implode!"

"Jeez, over dramatic much. Fine. Come in," she said, far from friendly.

"Keira!" said Harry, a little surprised. "How did you...?" He looked at Ginny questioningly.

"Don't ask me, I have no idea. She just knocked on the door and demanded to see you."

"Listen, Harry—," I started. I then looked pointedly at Ginny. She rolled her eyes and walked back to the main party. "Harry, I need your help. Because I know who you are now and there's a fully armed warship on its way to planet Earth."
