Collision Course (HP - Doctor Who) BOOK 1

Beginning of term and the first class

Hello, fellow Human Entity.

Harry's POV

I can't believe that an insane death eater like Crouch Juniour is managed to get into Hogwarts! I mull over how Professor Dumbledore is probably taking care of this as I chew a slice of gammon absent-mindedly. Hermione is chatting with Ron in a hushed voice, probably so people couldn't over-hear, about how he looked like a famous muggle actor called David Tennant. That was pretty interesting, I suppose, but still not really comforting since obviously muggles couldn't get into Hogwarts, let alone know what it was.

My train of thought was cut off by Professor Snape coming through the door at the back and telling us to go back to bed in a more intense tone than I'd ever heard him talk before, like he just found out something shocking and still couldn't believe it. Understandable. I mean, if someone everyone thought was dead and had been insane for a long time then just appeared out of nowhere, perfectly sane and alive, I'd be pretty alarmed too.

Once again, I'm snapped out of my thoughts my someone, this time by Hermione telling me to pay attention to the password, which was 'mimblewimble'. What was up with these passwords? They're so weird sometimes. Pushing that aside, I went up to my room and shortly went to sleep...

Morning time!!

Doctor's POV

I hopped out of bed, quickly getting ready, when I heard a knock on my door. Slipping my pin-stripped suit on, I opened it up. It was Severus, clearly making sure I wasn't doing anything suspicious or illegal or anything.
"Ah, morning, Severus! Popped down for a visit, have you?"
He rolled his eyes.
"I still don't trust you, 'Doctor'. I came to make sure you weren't doing anything you shouldn't be." Yep, it was what I thought: he was still stubborn about me being evil. Oh well..
"Well," I said, looking at my Gallifreyan watch,"breakfast is starting about now, so I best be off. Allons'y!"
I took a slightly longer way round so I ended up in the room at the back of the hall, so as to not surprise the students so much. As I got there, I heard the headmaster saying something along the lines of 'We made a mistake, that man was not a death eater' or something like that, so I walked through the doors and stood beside Dumbledore, grinning.

"Hello, everyone! As the Headmaster here may have told you, I'm the Doctor, and I'm your new astronomy teacher!" I took a seat between McGonnogal and Madam Pomfrey as a polite clapping filled the hall. I could of sworn I heard Hermione mention something about my name. Maybe she'd heard of me somehow? Who knows? Either way, I ate a quick breakfast and took a few Bannanas: the ones I always carry with me were running low (Yes, it's true, the doctor carries an in-expendable amount of Bannanas with him (or her, I guess) at all times).

Skip to first class

"So... astronomy. Astronomy, astronomy, astronomy.. what can I tell you about astronomy? Well, everything you need to know and much more. But that's not important this lesson: it's about what you can tell me. Nothing too serious, just a few rules and a quick little assessment, then maybe I'll tell you a story or two of some adventures of my own with certain planets. But first, I'll just make sure you're all here."
After a quick roll call, I continued.

"Okay then, first some ground rules.
1. No hanging over or going to the other side of the railings. I think that's a given, but, hey, you never know with kids these days.

2. No messing with any equipment you borrow. If you need something for any reason--"

I heard a snobby voice saying,"That'll be you, of course, Weasle." I straightened my back and march over to him.

"Mr Malfoy," I waited until he was paying attention to me, "I'm sure Mr Weasley would care about what you just said if, one, it was true, and two, it wasn't so boring, un-original and dull, much like yourself. However, it is neither of those things, so I kindly ask you to shut up and refrain from making such jokes in the future, otherwise there will be consequences. Understand?" I asked, switching to a slightly intimidating persona. The effect wad instant: all the Gryffindors and half the Slytherins were laughing at Malfoy.

"Anyway, as I was saying, if you need anything, just ask me and I'll get you it, but if you can't be responsible with it, I can't trust you enough to let you have it.

3. As you saw a minute ago, I can have a bit of a temper, and I'm not scared to humiliate you in front of your peers, though as long as you act responsibly, we wont have a problem. Alright?" The entire class nodded, though some were more reluctant than others. I handed out a three-page assessment and charmed them to spread out amongst everyone.
"Now, is there anything before we begin? No? Good!" I clasped my hands together, "Then you may begin. You have 45 minutes."

Time skip

"Time is up!" I say, playing the theme from that muggle show "The Chase". I don't think anyone got it, barr a few muggleborns, but it was funny to me. I summoned all the papers to my desk.

"Alright. We have enough time for me to tell you one story, so how about the day I met one of my friends? So, it all began with..."
By the end of the lesson, they all knew how I met Rose and what happened that day (with it edited to look like my current form, of course). Needless to say, some were sceptical before I showed them proof, a memory, in fact. After that, I think they all thought I was awesome. That was always a bonus!

Skip to a couple of classes later

I heard people walking and talking loudly through the hallway from behind my portrait. I swore I heard someone, I think it was Harry or Hermione, say how it reminded them of something they'd seen on muggle TV. I stepped outside and greeted all the students.
"Hello there!" Various versions of "Hi, Doctor/professor" rung out. "I heard all of your questions about my portrait (It's Gallifrey Falls No More) so I thought I'd come and answer them all. Ask away!"

"Uh, well, sir, if it's an oil painting, then--"
"How come it's in 3D?" Hermione nodded, "Well, see, because it's a.. well, it's complicated. It's actually a slice of time, made into a painting. That's how most paintings and artworks are made where I'm from."

"What is this a painting of?" A smaller kid asked, though still clearly in the same year as the others.
"It's a picture of Arcadia, my.. home town. This is Arcadia on the final day of the Time War."

"Time War? Why is it called that?" He asked curiously, head tilted to the side a little bit.
"Oh, uhh, because it went on for years. A century, ar least."

Before anyone could say anything more, the potion's classroom door swung open as the potions master swirled dramatically into view and all of the students scurried into the room and the door swung shut again.

Sorry for the sudden ending, I just couldn't come up with a way to end it lol.
