The third chapter is here! I was going to add another section to this chapter, but thought I had been long enough writing it. Hopefully you guys still have plenty to read from here. Next chapter might not be as long as the previous ones (although 'might' is an important word here; who knows how much detail I'll get into!). Anyway, without more delay...

Time Sitch

A Kim Possible/Doctor Who crossover

Chapter 3

Monday, September 22, 2003 - Middleton High School

Kim went over to her locker - as per usual before lessons began - after arriving at school. It had been a quiet evening the day before, and Kim was quite glad she didn't have to rush in at the last minute like most times after missions.

She opened the locker door and began to sort out what she needed for her morning lessons. Taking up a large space of the locker was a computer, which had a printer connected to it. The computer had been set up by Wade to make it easier for Kim to receive her mission briefings while still in school. A few moments after she had opened her locker door, the screen flickered to life to reveal Wade himself.

"Hey Wade. What's the sitch?" Kim asked.

"Got a message from the scientific research centre that was broken into yesterday", Wade began. "They said they've just had a random visit from a scientist who claims to know what the black cube is all about. More specifically about what's inside it."

"Seems like strange timing for someone to turn up and only just saying they know something about it", Kim commented. "Anything dubious about this scientist?"

"As far as they can tell, she has legitimate identification and credentials", Wade said. "The only odd things about her are her dress sense and her weird personality."

"Pffft, never heard of that one before", said a familiar voice. Kim looked to her right to see Ron leaning against the neighbouring locker.

"Hey, Ron", Kim said. "Wade's calling about a scientist who knows something about the cube object that was stolen yesterday."

"They said they would appreciate it if you could come over again and talk to her as soon as possible", Wade said to Kim.

"Tell them as soon as school is finished, we'll come right over."

"Will do, Kim. Catch you later." And with that, the screen turned off.

"Seems like a coincidence that a scientist just suddenly turns up and claims to know what's what with this black cube", Ron stated.

"That's what I said myself to Wade", Kim said.

"Well it makes me more suspicious about this object and who might be behind it. What if this so-called 'scientist' is just trying to get their grubby hands on it for their own goals?"

"Wade said this person had the right credentials to walk into the scientific research centre. They would have noticed if she didn't know what she was talking about", Kim replied patiently. "You should probably be more concerned about your history essay at the moment. Got anywhere since yesterday?"

"Well, I did start it", Ron said. "As in, I've written the first paragraph. So I've only really introduced the subject of the essay. But at least it's something…?"

Kim was standing there with a raised eyebrow, while clutching her textbooks. But not to belittle Ron; he was her friend, and more than anything, she was concerned for him.

"I'm going to be in trouble, aren't I?" Ron said.

"Yeah, possibly", Kim said cautiously, without overstating the fact to make Ron feel worse. But he still gave a tired sigh in response.

"First period is going to start soon. Better get over to history", Kim said to Ron, keeping a happy face to try make the atmosphere less negative. Kim started to walk down the corridor to the history classroom, with Ron trudging along with her.

A dark-skinned, black-haired teenage girl ran up alongside Kim. Her name was Monique. She and Ron were Kim's two closest friends, with the three of them spending a lot of their free time in school with each other. Monique was especially great for Kim in scenarios where Ron was inadequate to talk with her about certain topics (although mostly not of his own fault).

"Hey, Kim", said Monique. "I've just heard that Miss Williams might be ill…"

"Yeah, we already know", Ron sighed. "And I'm going to be in trouble with Mr Barkin because I've done almost nothing with my history essay."

"Ron, did you forget about it?" Monique inquired.

"I might have done", Ron responded.

"You need to spend less time going to Bueno Nacho and binge-watching whole series of TV shows, or whatever takes your fancy. None of it is going to help with your school work." Between her and Kim, Monique was the less sympathetic out of the two of them with Ron. She also wanted him to do well, but was straighter to the point about his flaws.

"Hey, at least half of my 'free time' is spent helping Kim save the world", Ron replied back.

Kim smiled at Ron, and then turned to Monique. "I'm sure it'll be fine" Kim hopefully said. "Most of the time, Mr Barkin just shouts at Ron, and I'm sure he's used to that by now."

"But Ron's not even done half of his essay", Monique pointed out. "I think Mr Barkin is going to give him a bit more than just a roasting."

At that point, the bell rang, just as the three teens entered the classroom. They sat at their desks, which were in the second row from the back. The rest of the students in the class had already arrived, and were preparing themselves for another gruelling lesson with Mr Steven Barkin. Monique, Kim, and Ron each took out their books and paper. Out of the three of them, Ron's essay was quite evidently the barest.

As soon as everyone had prepared for the lesson, Mr Barkin marched into the room. He was a very muscular man, with piercing eyes, and a dark-coloured flattop haircut. He was often the substitute teacher for many of the classes at Middleton High. So often in fact, he was treated as a regular and practically recognised as a full-time teacher by the students. At times, he seemed to have some control over the administration and organisation of the school. He was a stickler for high-standard work; anything less than satisfactory for him, and you could say goodbye to top grades, and possibly free time if he decided people needed to redo their homework again.

Mr Barkin came to the front of the classroom and faced the students, with hands behind his back. He then took a deep breath before projecting loudly, "Ok, listen up people!"

All the students were now giving their full attention to Mr Barkin, with silence falling on the room. Mr Barkin then continued to address them; "Yesterday, Miss Williams reported that she had been taken ill…"

"We know", said the whole class in unison. News of Miss Williams being ill had spread like fire throughout the school.

"Let me finish", Barkin demanded. "She had reported in to say she was ill, and would be so for the foreseeable future. Therefore, there needs to be a substitute teacher for this history class…"

Ron groaned and laid his head in his hands on the desk, in preparation for the 'inevitable'. But what Mr Barkin said next was very much unexpected.

"On this occasion, I am not going to be taking charge of this class", Mr Barkin said. The class continued to stay in silence for a moment, processing this fact through their heads. A second later, everyone began to cheer in a mini-celebration. Amidst this, Ron cried out a "Hallelujah".

"Silence!" Mr Barkin shouted. The class fell into quietness again. He then continued; "There will be someone else taking over the classes. He simply goes by the name of 'The Doctor', but he seems to know his stuff." He then turned towards the door, and called out, "You may come in now."

A skinny man - in a dark-brown suit with blue pinstripes - entered the room, and gave a friendly smile towards his new class. "Hello", he said in a cheerful manner. He sported sideburns and had wild, stuck-up hair. He was also wearing cream-white Converse All Star trainers, which seemed a little odd to the class. However, if Mr Barkin wasn't rebuking him for his dress sense, then the students didn't really care either. With the number of teachers falling foul of something every other week, Mr Barkin probably just wanted someone with some knowledge to help take the work load off him.

"This is 'The Doctor' ", Barkin stated. "I hope you give him a warm welcome. If anyone even steps a little bit out of line with him, you'll have to answer to me", he said threateningly.

"I don't think that's going to happen", said the gentleman known as 'The Doctor'. He continued to smile and seemed to be naturally friendlier, compared to Mr Barkin, who couldn't have been a further polar opposite.

"Well, I shall let you do your work", Mr Barkin said. He then walked out of the room without another word, and closed the door behind him.

The Doctor instantly went into action. "So", he started saying as he grabbed a piece of chalk and began writing on the black board, "my name, as already mentioned, is the Doctor." When he turned back to the class, he had written his name on it.

"Doctor who?" Monique asked.

The Doctor chuckled a little, and then pointed to her and answered, "You're not the first one to ask that." He then started walking around the room and said, "Just the Doctor."

He then paused for a moment. "I feel like I should start asking who's who in this class of mine. Wouldn't do at all if I had to start calling you 'Thing One', or 'Thing Two', or 'Thing Twenty Three'…" He then turned to look at Monique again, and asked, "So may I enquire you for your name?"

"Monique", she responded.

"That's a wonderful name", the Doctor said. "The Greek meaning for that name is of one being an 'advisor', and of one to be 'wise' through the French language. I suspect you are quite a confident and head-strong person, based on you asking me directly about my name. I wouldn't be surprised if you were the sort of person people took sound advice from."

"I'd like to think I'm a person to be trusted", she replied. She and Kim shared a smile and a look of recognition of that fact between them. Even though Kim had faced many tricky situations through her missions, she always went back to Monique whenever she needed advice. Especially to do with her personal life, school life, and crushes. Battling against Shego and talking to Josh Mankey were two totally different things, with Kim being more afraid of the latter.

The Doctor noticed Kim sitting next to Monique, and said, "I think I've seen you somewhere before."

Kim replied, "Really…? Ah, well, it could be because of having appeared in the news a few times to do with helping other people."

"Oh, of course!" the Doctor exclaimed, seeming to show some awareness. "I think I have read things about you recently in a number of newspapers, to do with saving the world. Pretty good stuff for someone of your age."

"No big really", Kim replied, being as modest as possible.

"Your name? Just to jog my memory" the Doctor said.

"Kim Possible."

"Nice to meet you Kim", the Doctor replied. He then said, "I just thought; you have a companion that accompanies you on your missions…"

"That would be me", Ron piped up, waving his left hand to make sure he got the Doctor's attention.

"Ah yes, I recognise you now. And what's your name?"

"Stoppable. Ron Stoppable", Ron said, trying to act cool and chill, but not quite managing to pull it off.

The Doctor didn't seem to take notice of this strange acting from Ron; he just responded, "Good to meet you, Ron." The Doctor smiled at him, and then walked over to his desk.

"Did you guys have any previous homework set?" the Doctor asked the class.

Everyone remained silent, and then one stereotypically-nerdy student raised his hand and said, "We had an essay that was due in for today." Instantly, all eyes in the room turned to him, with dagger stares coming from all the students.

"Really?" the Doctor said, "Let's have a look at what they were about", indicating to the nerdy kid to see his essay.

The student passed his papers over to the new substitute teacher, who flicked through all the pages at rapid speed. The Doctor looked at the front page again, and then said, "American History? Do you guys do much history from other eras and cultures?" The Doctor hadn't really paid much attention to the specific subject that the students had had to write about, but he seemed to have caught the gist of it. And clearly this teacher didn't favour 'American History' that much.

The Doctor dropped the essay to the floor, and then quickly moved over to the blackboard again. "Tell you what, let's take a look at the Romans", he said with a sudden twinkle in his eye. The students looked on in confusion, but also in awe, at the pace which the Doctor was suddenly going at. He rubbed off his name from the board, took a chalk stick, and then quickly wrote, 'Romans'. He drew a circle around that word, and then turned back to the class.

"So… Romans", the Doctor began. "What do you all know about them?" He continued to stride around the room while waiting for replies, and seemed to be almost impatient for them to answer.

The Doctor decided to choose a random student after a few seconds of no one responding. He pointed at a girl who had a shoulder-length, brunette shag-styled haircut. "You", he said.

The girl looked up from smoothing her nails with a nail file, clearly not wanting to be in the class. She was not interested in the lesson, not even with Mr Barkin out of the way.

"Who, me?" she responded.

"Well, yes. I'm not exactly pointing at the jolly green giant, am I?" the Doctor said, countering her 'couldn't care less' attitude.

She sighed, and then answered, "They wore funny hats and had weird fashion senses."

The Doctor raised an eyebrow and asked, "May I ask what's your name?"

"Bonnie Rockwaller", she replied, in a manner as if the Doctor was meant to know who she was.

"Right, Bonnie, I'm going to need a little bit more to work on than just 'they wore strange clothes' ", he said. He then added, "As it happens, the 'funny hats' you're referring to are the helmets worn by the soldiers. And as for the clothes, they would be quite practical for some of the warmer areas of Italy or other hot countries. Not so much Britain, although I guess that's where the trousers come in…"

"Excuse me, but what are 'trousers'?" Bonnie asked.

"Damn it, I keep forgetting this is America", said the Doctor, as he facepalmed himself. "Sorry, I meant 'pants' for you lot."

"Whatever", Bonnie responded in a dismissive manner, going back to taking care of her precious nails. The Doctor rolled his eyes, but decided to not bother questioning her anymore. The rest of the class were still giving him enough attention that he could work with.

"Anyone else?" the Doctor openly asked the whole class. "Come on, I know main American history for you guys has only really been since the mid-18th century, but you must know something about the Romans."

"If I remember correctly, they had a large empire that spread from Britain, all the way down to North Africa and Israel", Monique piped up.

"Yes, they did at the peak of their powers", the Doctor exclaimed. "Good start! Let's keep rolling", he encouraged the students.

"The Romans had a republic form of government, before they became an 'empire' ruled by a single emperor", Kim stated.

"Correct", the Doctor said. "If we're going to be technical, the first form of government they had was of a monarchy, with the people voting for who was to be the next king each time the previous one popped their cogs. Then Ancient Rome became a republic, etc. Other than that extra fact, you were spot on."

The Doctor decided to turn to Ron and see if he had any answers. "I feel like you must know something about the Romans, Ron."

Ron looked a little surprised, and said, "Err, really?"

"Of course! You must be itching to get some facts out of your mouth", the Doctor said.

Ron laughed nervously, and then said, "I'm not sure I'm clever enough to give you any good answers, Doc".

"Hey, look, don't you worry", the Doctor responded. "I don't think you could do any worse than Miss Rockwaller over there."

"Did someone say my name?" Bonnie called from across the room. The Doctor ignored her and kept looking patiently at Ron.

"Well", Ron began. "According to myth, the city of Rome was founded on April 21, 753 BC, by twin brothers called Romulus and Remus…"

"Yes…" said the Doctor, putting his hands in his pockets, suggesting he wanted to hear more from Ron.

"Who were apparently descendants of the Trojan hero, Aeneas, who was written a lot about in Roman mythology and was treated as the first hero of Rome…"

"Go on."

"And Romulus and Remus were saved and raised by a female wolf - when they were babies - away from the clutches of Amulius, who was king of Alba Longa."

"Excellent knowledge, Ron!" exclaimed the Doctor, who was clearly pleased with the stuff the blond-haired teen knew about. "What about the 'actual' origins of Rome?"

"Well, Rome grew from settlements around a ford on the river Tiber", Ron stated. "When it started as a village, it was probably founded sometime in the 8th century BC, but possibly as far back as the 10th century BC, by members of the Latin tribe of Italy."

"Brilliant", the Doctor said, walking back to the board. "We have a Roman-history enthusiast over here."

Kim was quite shocked that Ron had been able to say that much about Roman history (and for that matter, a bit of Roman literature). She quickly leaned over to talk to him and asked, "Where did that all come from, Ron? You seem to know a lot on this subject."

"Just watched a film called 'Gladiator' ", he casually replied. "It's a sick movie, and it got me interested in that part of history. So I thought I would do a little bit of research, just out of curiosity."

"I presume you also checked up on the accuracy of the film itself?" Kim inquired.

"Yeah. There's quite a bit of it that's been made to be narratively more compelling. But Roman history is still awesome!"

"If you ignore the brutal assassination of leaders and emperors, slavery, and slaughtering of many innocents who weren't fighting against the Roman Empire", Kim pointed out.

"True", Ron admitted, "But it's still an awesome part of history, nevertheless."

Kim just smiled back, happy that Ron had managed to study a subject properly, as well as making it one of his obsessive interests that this time would actually help him with his school grades.

The Doctor had returned to the front of the classroom, ready to deliver a bundle of information to the class. "Tell you what", he said to the students. "As we've just had Ron talk about the formation of Rome, let's start from the very beginning…"
