"Oh, this is brilliant! What are their names? Are they developing like a human or a Time Lord? Hmm, what should I have them call me? I suppose I'd be more like an uncle than any other sort of relative. Uncle Doctor? Is that odd? Perhaps just 'the Uncle'. Oh, but then they have their Uncle Tony, I suppose, so that's not going to work. Is it still just Tony for Jackie and Pete? Well, besides Rose, of course. How long has it been for you anyway? How was the pregnancy? Was it terribly difficult for her? Was this planned? I thought we wouldn't be able to impregnate without some scientific intervention... Did you do some gene manipulation? Why are you two staring at me like that?"

"...you about done there?" Clara asked, her eyebrows raised. She looked over at the other Doctor. "Do you get like that too?"

"No," he replied quickly. He paused and absentmindedly rubbed the back of his head. "Well, maybe a bit... well, when I say a bit, I really mean that -"

"Oh no, don't you get started!" Clara interrupted, holding her hand up.

"Right. Sorry." The other Doctor looked properly admonished.

"So?" the Doctor asked, looking at his... brother? expectantly. Clara decided to think of them as brothers. It was easier for her to wrap her mind around.

"No," Clara stated firmly, pointing at the Doctor. "Before we get into all of that, I need to know what the hell is going on! How did he hear his kids if they're in a parallel world? And why didn't you ever mention any of this before? It's kind of important to know a) if your metaclonebrother person is going to just show up in the halls and b) that if you ever lose a limb, another you will grow out of it!" She paused and smacked her Doctor on the arm. "Are you like a worm or something?"

"No no no, I'm a unique event in time and space. Never been anything like me before," the other Doctor replied, grinning at the echoes of his conversation with Donna.

"And he shouldn't be able to get here!" the Doctor added. "Travel between parallel worlds is impossible now."

"Yeah... Rose doesn't let me use that word anymore," the other Doctor commented, tugging on his earlobe.

"He can hear the children because Time Lords have a sort of telepathic network with one another," the Doctor continued, ignoring his metacrisis. "It's also why he needed me to be quiet up here." The Doctor tapped his temple. "I'm not used to shielding my thoughts on that level anymore."

"Telepathic? What like you can read minds?" Clara stepped back, a look of mild horror and disgust on her face. "Are you reading mine? What sort of weird mind things have you been up to?"

"I'd need physical contact to establish a telepathic connection with a non-telepathic species such as human," the other Doctor replied. "I can show you, if you'd like."

"Uh..."

"I'd never go into someone's mind without permission, Clara," the Doctor added. "Not unless it was a life-and-death emergency."

"What kind of physical contact? Oh God, it IS a snog box, isn't it!"

"No!" the Doctor protested.

"A what?!" the other Doctor exclaimed at the same time, staring at the full Time Lord. "What in Rassilon's pajamas have you been up to?!"

"It's not a snog box!" the Doctor exclaimed. "And the last time I had to make a telepathic connection with a human, I headbutted him."

"What?!" the other Doctor exclaimed again.

"You are so not headbutting me," Clara shook her head, crossing her arms.

"Seriously, what have you been doing? Headbutting people? Making the old girl into a snog box?" The other Doctor shook his head and turned to Clara. "Ignoring the violent rugby player over there -"

"Oi!"

"I establish a telepathic connection by placing my hands on the other person's temples. It's completely painless. Like I said I can show you if you'd like. But later." He turned to the so-called violent rugby player Doctor. "First I need to find my wife. And then we find a way back to Tony's World."

Jackie Tyler stared hopelessly at the door the Doctor had disappeared behind. If it wasn't for her grandbabies, she would have followed him straightaway. She turned around and leaned against the railing, looking down over the entryway. What was she going to do if they didn't come back? Or if they didn't come back for years?

She didn't know anything about raising Time Lords. And those sweet little tots definitely had smarts that didn't come from Rose's side of things. What if there's some sort of time thing they need to happen? She sighed and closed her eyes.

At least she'd have Pete and Tony to help her. Much easier than when it was just her and her Rose on the estate all those years. Actually, she should probably see if Tony was around. They tended to be a bit of a handful when they woke from their naps.

Jackie turned back towards the hallway and fished her mobile out of her pocket, but before she could dial, the sound of a door opening grabbed her attention.

"Mum, what're you doin' standing in the hall like that?" Rose asked, walking towards Jackie out of her and the Doctor's bedroom. "Seriously, with the kids up and everythin'... they're chatterin' so loud, I could hear 'em in our room."

Rose shook her head and walked past Jackie and went straight into the twins' room, leaving Jackie gaping, completely speechless in the silent house.
