Ady sat in her bedroom, her arms wrapped around herself as if she were physically trying to hold herself together. She was doing something she almost never did.
She was sobbing her eyes out.
"Why am I so upset?" Ady thought to herself. "I should feel happy. I know who my parents are now; I've been waiting my entire life to find out. And, they're time travelers who have shown me things I never thought were possible."
Ady sniffed and sat up, but was quickly overcome with another round of sobs.
"Yeah, the really awesome parents who leave you to rot in an Earth orphanage when you're not even fully human," she thought. "Sounds great."
It was a lot to take in. Not only had she just found out about her parents, but finding out that she is partially an alien is not exactly a tidbit of information that someone finds out every day.
"I wonder if the Doctor can explain it more to me-" she started. "Oh wait, I pissed the stubborn alien off. Never mind."
As if on cue, there was a soft knock at her door as said stubborn alien poked his head into her bedroom. Seeing Ady's tearstained face and reddened eyes, he crossed the room and hugged her tightly.
"I don't think I've ever seen you cry before," he noted.
"Really? That's the first thing you say to me?" She pulled back from his hug and glared. "You tell me I'm not human, say you're my dad, and then comment on the fact that you've never seen me cry?"
The Doctor sighed.
"I'm sorry," he said. "I'm so, so sorry." He cradled her face in his hands.
" I didn't know something like this would happen. I had no clue we would ever find you. I hoped that we would, someday, but I never thought we actually would."
The Doctor moved his hands from Ady's face to her shoulders.
"But, I can tell you one thing for sure," he said, raising his eyebrows. "You have become exactly the young woman we hoped you would since the day you were born. Feisty, independent, and strong, yet still caring and loving. You remind me so much of your grandmother."
Ady was shocked at the sudden mention of her mysterious grandmother.
The Doctor nodded.
"You do remind me of her. And you know what? I couldn't be prouder to say that you are my daughter."
Ady's eyes were wide as she stared at the Doctor. They began to brim again with fresh tears.
"Nobody's… ever… said anything like that about me before," she said, wiping her eyes. "Ugh, and you're making me a blubbering mess again!"
The Doctor laughed.
"So," Ady began, with a raise of her eyebrow. "Does this mean I have to call you 'Dad' now?" She smirked.
"Please don't!" the Doctor exclaimed, shaking his head vigorously. "That would be so… strange."
Ady snorted in laughter.
"What? I can't start calling you Dad? Papa? Daddy-kins…"
"Ady!" The Doctor groaned, shoving her shoulder playfully.
"I'm kidding. I don't want us to change," said Ady. "You're not going to start being that awkward father figure, are you? Scrutinizing boys and being overprotective?"
"I'll try," said the Doctor. It was his turn to laugh.
"I'm kidding, too!" he said, throwing his hands up in defense and artfully dodging Ady's signature pillow-throw-to-the-head. "Nothing will change. We are still our little TARDIS family, only now we really are, officially, family."
Ady smiled. Family. It had been a while since she could truly say she had one of those.
"Doctor, am I going to change any?"
It had been a few days since the "reveal," for lack of better terms, of Ady's true self. The Doctor glanced up from the TARDIS controls, confused.
"What?" he asked, half listening. He pulled out his sonic screwdriver and attempted to mend a switch he had broken earlier that day.
"I mean, now that I know I'm not really human," she started.
"You're partially human," explained the Doctor, still not looking up. "And partially Time Lord."
"What is that supposed to mean?"
"It means that whatever way you were growing up is the way you will stay. You've been surrounded by humans your entire life, so you know the human norms. However, you also are accustomed to yourself. You know how you, personally, are. And that won't change just because you found out your true genetics." The Doctor paused, finally looking at Ady. "Well, I partially take that back."
Ady stopped in her tracks.
"There is something that… could change… but it's nothing to worry about soon," he said quickly an somewhat defensively.
"What is it?"
The Doctor could tell he had struck a nerve with her. He sighed in defeat. "It's called regeneration."
"Never heard of it."
"Well, I'm sure you haven't." He sat down on the bench in the console room, and patted the seat next to him for Ady. "Okay, so you know how I'm over a thousand years old, right?"
Ady nodded, joining the Doctor on the bench.
"Whenever it is time for me to die, whether it is from old age or something kills me, I regenerate instead of die completely. Every cell in my body becomes new. I am still the Doctor. I have all of my memories from my past, but I am essentially a completely different person.
"So, you've been other people before."
"Precisely. I'm on my eleventh regeneration."
"Eleventh?" Ady choked.
"Yes, eleventh. And, I'm sure if you look in the right place, you could find some pictures of my old regenerations in the TARDIS files. But enough of that for now-"
"What does that have to do with me? Am I going to regenerate?" Ady asked, looking slightly nervous.
"We aren't sure. Ever since you were born, I could never figure out if you had enough Time Lord in you to regenerate or not. But honestly, I'd rather not test that theory."
Ady smiled. "Me neither."
