AN: This is an idea that popped into my head after reading that Patrick Troughton (2nd Doctor) is the maternal grandfather of Harry Melling (Dudley Dursley). Of course, my reaction is, "Oh snap, Dudley's a Time Lord." And then this happened. I don't own any of these characters (even the Evans's, whom JK Rowling never named / described much in the books... or, if she did, I couldn't find them). Anyways, enjoy!

The day Lily's letter came in the mail, Sylvester and Rosemary Evans could hardly contain their shock.

It had never once surprised them that she could do strange things. Even for a young Time Lady, she was a particularly exceptional child. Her understanding of botany and chemistry was incredible, far beyond that of her sister's. Though they had tried to engage both of their children in science, it had only really stuck to Lily. Petunia was, unfortunately, much less bright, always trying to blame Lily's success on "magic." Of course magic existed; the Evans's had met many a great witch or wizard in their own time. But these wizards had all been humans. Time Lords did not possess magic. They couldn't possibly believe an excuse like that.

Until now, that is.

Lily's letter explained how there was a school called Hogwarts where all witches and wizards currently residing in the United Kingdom would learn how to control and practice their magical skills. The letter also explained how, because Lily was born of non-magical parents, they would be sending a representative over at a convenient time to explain the scenario and answer any questions they might have.

On the one hand, it was all very exciting. The first official Time Lady with magic. Not that "first" meant a whole lot to a race of time-travelers, but still. They had never once encountered another of their own race who possessed these capabilities. This had to be an anomaly. On the other hand, they were supposed to be spending a few decades on Earth to study it for the Gallifreyan records. How were they supposed to explain to the Council that they had, in fact, contributed to its history?

Not to mention that their children were supposed to be inconspicuous. The people of Earth didn't need to know about other worlds yet. In fact, space contact wasn't supposed to be discovered for another couple of centuries in Earth years (to be fair, they had landed a few men on their only moon, but to call that space contact would be akin to sending a hermit to the edge of his cave and calling him a people person).

Rather than be discouraged, though, the Evans's took this to be an opportunity. While the world of Gallifrey might be pleased to hear that they gave birth to the only magical Time Lady, nobody else had to know all of the details. Indeed, while any Time Lord worth his spit had met a wizard at least once, not all wizards could say the same for Time Lords. And the wizards were a secretive people, to be sure. They wouldn't want any word about their existence getting out to the other humans, so, if they knew of Lily's special situation, they would certainly take extra precautions to protect her identity.

And so the Evans's were rather contented with their daughter's achievement. Petunia, however, was not.

Hardly an hour would pass when Petunia would wail something about how her younger sister was a freak of nature. It was unsurprising, really. The two were raised amongst human children, and how else would a normal human child react? It did not help that, after an unfortunate incident with a toaster some years back, Petunia had been forced to regenerate. Such bad luck was soon followed by a less attractive face, making the girl particularly envious of her sister. Even worse, following the regeneration, the Evans's had to move to Cokesworth. It would not do for their eldest daughter to have suddenly and unpredictably changed appearances when she ought to have been dead. Petunia, of course, felt burdened with guilt for this. Had they been on Gallifrey, this would not have been a problem, but, of course, they were stuck here on Earth. Typical.

Nonetheless, it could get tiresome.

"Mummy!" Petunia would screech, "Why is that Lily gets everything? She gets to be a witch and she hasn't used up any of her regenerations yet!"

"Calm down, Petunia," Rosemary would reply, her nose often stuck in a fascinatingly primitive Earth book on gardening. "You are a Time Lady. All good things shall come to you in, well, time. She may have good things now, but yours will soon come. I can scarcely tell you how many times I've felt the universe was acting unkindly to me, and then I would look out at my future yet to come and relax once more."

"But, Mummy, I've already used up one of my regenerations! My future won't be as long!"

"Well, Petunia dear, if you were so concerned about that, perhaps you shouldn't have dropped your TARDIS particles in to a toaster. Which reminds me, go check your TARDIS's growth. Run along, dear." Rosemary made certain that both of her children were growing their own individual TARDIS's in a controlled environment in the cellar.

Rosemary was one of the most advanced botanists back home on Gallifrey. Having heard stories of Hogwarts' excellent Herbology department, she was very excited to get to see how the wizards viewed plants differently from the average non-magical human. Besides which, because the wizards were so expert at keeping their secrets, no Time Lord had thus far managed to take note of their plants (or, for that matter, any of the rest of their magical enchantments).

As the days passed after Lily's letter arrived by owl, the Evans family (save Petunia) waited patiently for the arrival of a wizard to the house. Finally, about a week and a half later (10 days to be exact, as Lily had been counting), a tall, thin woman came to their doorstep. She told the Evans's that her name was Professor Minerva McGonagall, and that she taught Transfiguration at Hogwarts.

"Now, I know that the parents of many Muggle-born wizards are often shocked to hear that such a thing exists, and many are hesitant to let their children learn here," she explained, "but, I assure you, Hogwarts is an excellent, well-established school in the wizarding community. Now, if you require, I can prove my magic to you-"

"There's no need," said Sylvester. "I believe you. I have met quite a few wizards in my own time."

"Oh?" For once, it was Minerva who was shocked. "And what would 'your own time' be, precisely?"

"Well, there really isn't one specific one. I drift around a bit. I've been here for about two decades now; a short time, really, when you consider that Rosemary and I both graduated from the Time Lord Academy about, oh, two and a half centuries ago?"

"Well, then." Minerva was thoroughly confused. "Should I inform you with the procedure with which Lily should obtain her school supplies?"

"Certainly."

"I'm afraid you won't be able to go with her, at least not this year. We try to keep as many Muggles out of the confines of the wizarding world as we possibly can. Of course, if you're her parents, it would be rather difficult to keep you from knowing what's happening."

"That's reasonable."

Minerva was getting quite unnerved. The adults in front of her ought to have been losing their heads, and, yet, here they were, totally calm. "I will be back in a few weeks to take her to Diagon Alley, one of the most popular wizards-only shopping areas in all of Great Britain."

"That sounds splendid."

Young Lily looked up at the professor in front of her. "Ma'am, I know that both of my parents have seen wizards and witches before, but I haven't. I'm still only eleven. D'you think you could show me something?"

For once, a reasonable response. "Of course, dear."

And, with one flick of her wand, Professor McGonagall turned into a cat. She turned from a human being into a cat, right in front of Lily's eyes. Lily had seen quite a few things in her eleven years (for goodness' sake, she was growing her own time machine in her cellar), but this was new to her. There had to have been a scientific explanation for it, she knew it. Nothing lacked a scientific explanation, even if that explanation hadn't been discovered yet.

Lily decided, right then and there, that she was going to discover it.
