A/N I'm sorry I'm sorry I'm sorry! However, I believe I warned you about how bad an updater I am at the beginning of this story. I know it's been a while! (Surprise! I'm not dead after all! Still here, alive and writing...ish...)

Again, sorry! Now, to the chapter! (there wasn't actually any point in this author's note. I just like including them!)

Disclaimer:

Me: Yeah, I now own Doctor Who

BBC: Excuse me, no, you don't. We do.

Me: You Sure?

BBC: Yes.

Me: Completely?

BBC: Yes, we are completely sure that you don't own Doctor Who.

Me: But couldn't I just own it a little bit, like, every third weekend and second Tuesday of the month or something?

BBC: No. Absolutely not.

Me: Why? :(

BBC: This conversation is over!

Yeah, soooooo...if you didn't get it, I don't own Doctor Who. If I did, Alex Kingston's name would appear in the opening of every episode and River would never, ever go to the library. Ever. So I probably won't ever own it. Sorry.

The Doctor...um, make that Professor Smith was interested in the new girl in his class that morning.

He, like every other professor, had known about the Carter twins and seen their test scores (they had been...impressive to say the least) but the numbers themselves had given no indication of what their personality was like.

And, as it turned out, Olivia Carter, or, as she had introduced herself, 'just Livvy, thank you very much,' was a brilliant, clever, somewhat insane, tough, and had absolutely no regard for authority.

She had waltzed in precisely five minutes late, evidently on purpose, as he had seen her lurking about in the hallway when he had entered five minutes early. When she entered, he stood up to greet her, extending a hand.

"Hello." he said, jovially, "I'm Professor John Smith. You're Olivia Carter, right?"

Livvy gave him a little wave.

"Hiya, Doctor Smith." she said, grinning evily.

The Doctor, who never gave out his official 'title,' looked at her in shock. She laughed, and leaned forward so that only he could hear her.

"You're registered as a doctor in your official application. It's funny that you don't normally go by it. It'd be a nice benefit for the school. Parents like it when their kids are taught by an official sounding doctor."

The Doctor narrowed his eyes, frowning at her.

"How do you know that?"

The girl laughed again. It was really kind of annoying.

"You really need to update your security system, timelord. What is that anyway, some stupid club you belong to?"

"Um, yeah. Something like that." he said, stunned. "Now, have a seat. We're studying-"

"The crucial differences between Astrology and Astronomy and the key elements of each as an introduction to your new unit on the solar system. I read your lesson plan too."

Livvy breezily walked down the aisle, took the one empty seat, and sat down, leaning back with her hands behind her head.

If this little exchange wasn't bad enough, Livvy continued to be a nuisance throughout his entire lesson, cutting in frequently with comments and even correcting him. The Doctor started purposely throwing out incorrect facts on purpose, things that no ordinary 13 year old would possibly know, but there was no tripping up Livvy. Halfway through the lesson, the Doctor called her up to the front of the room, handed her a worksheet, and told her to keep quiet. Surprisingly, she did as she was told and remained quiet and studius through the rest of the class.

She left without a word, but with a brilliant smile as she dropped the stack of papers on his desk.

"C1, D7, F4, and B14 are all wrong, or at least poorly worded." she informed him before heading for the door. "See you around, Professor Smith!" she called as she left, the grin never leaving her face.

As the new girl, she could have chosen to make a number of different first impressions, and it was clear that Livvy Carter had chosen to be a bad girl. For some reason, it reminded him of River.

As he left the classroom that day for lunch, the Doctor had decided one thing about Livvy.

He really liked her.
