I know this chapter contains some not so good summaries and for that I apologize profusely. Be patient with me please. It gets better.

"My mum and dad got married a year or so after the Doctor left them in Pete's World." Kali explained once they had settled down in the kitchen with a cup of tea. The Doctor was still oddly quiet but Amy had insisted on understanding what was going on.
"Wait a minute." the red head interrupted the young brunette. "I thought you said he was your dad." she said with a nod to the Doctor.
"In a way, yeah he is. It all started right after his ninth regeneration, when he first became this tall, cheeky, pretty boy."
"Eh!" the Doctor look at her, slightly offended.
Kali just smiled slyly. "Sorry Doctor but it's true." She turned back to Amy before continuing. "He lost his hand in a sword fight on Christmas. That hand was kept by Torchwood and eventually found its way back to him. My mum traveled with him for awhile but became trapped in a parallel universe for two years, after the battle of Canary Warf. Worse two years of her life, she always said." She looked down to avoid the Doctor's gaze. "She spent the entire time working out a way to get back here. When she and the Doctor were finally reunited, he got shot by a Dalek but instead of regenerating, he sent the leftover energy into the hand."
"I'm sorry, but what is this regeneration thing you keep talking about?" Amy cut in to ask.
Kali glanced at the Doctor and, after a moment, was certain he wouldn't answer Amy himself. She turned back and quickly explained the basics of regeneration. Amy listened and nodded slightly to tell the brunette she understood.
"Anyway, Donna ended up touching the hand which caused a biological meta-crisis. A half human, half Time Lord Doctor was created out of that hand and Donna gained the mind of a Time Lord. 'Course it was too much for her human mental capacity. She," Kali swallowed back tears and restarted. "She lost her memory, to protect her brain. She lost everything that had happened, that she had done, that she was capable of."
The Doctor shifted uncomfortably in his seat.
Kali cleared her throat. "Anyway, the Doctor returned my mum, grand mum, and their friend Mickey to the parallel universe. My mum didn't want to leave him but he lo…well he left his half human self there with her. They grew old together, even died hand in hand mere minutes apart. Inseparable, those two." She stopped, lost in thought and a small, sad smile graced her face.
Amy's brows knit together in confusion. "You said they grew old together but you can't be more than"
"Nineteen." Kali supplied.
"Nineteen' Amy echoed. "How old were they when they had you?"
"Oh, mum was only late twenties when I was born."
"But how is that possible?" Amy asked, lost.
Kali looked straight at the Doctor and said two little words.
"Bad Wolf."

I'm trying my best to get these up as fast as I can because I know how hard it is to wait for new chapters. And hang in there! Jack is coming soon. Promise
