A/N: The prompt for this one involved Twelve, Rigsy, and their new tiny humans that they were minding. Needless to say I instantly thought of the Time Twins and ran with it. This also tries to help fill the gap between where the canon diverges and where this storyline picks up. Hopefully it works.

"So, um, you didn't have that last time we saw each other," Rigsy noted, eyeing the double-papoose strapped to the Doctor's chest. He bounced Lucy on his knee, keeping his daughter happy, while the Doctor tried to remain dignified despite the infants drooling all over his jumper. They were in the park, resting one day while their wives took a spin around the galactic shopping center, Clara having promised Jen that the last time they'd met, when she and the Doctor had dragged her husband back from Trap Street after a harrowing experience that involved clearing his name and scolding an immortal who really should have known better than to make every crime punishable by death. It had only been a couple weeks for Rigsy and Jen, but for the Doctor and Clara it had been well over two years.
"James and Alison were… a surprise," the Doctor admitted. "A surprise we very much wanted, mind you, but Clara and I were under the impression we'd need the TARDIS's medical equipment to intervene when we were ready."
"Kids don't always wait for Mum and Dad to say they're ready, do they Lucy?" Rigsy smirked. The girl giggled and reached for her father's face, as if she knew he was talking about her. "Jen and I got a bit over-confident and… well… best surprise we ever had. I'm sure you and Clara can relate."
"Not sure about that," the Doctor muttered. He disentangled Alison's hands from the holes in his jumper and pet her hair, so soft and fine it felt like silk. "It's rare for my kind to breed after we make the full transition from the broad Gallifreyan to elitist Time Lord, and not merely because we don't want to…"
"You sound so depressing," Rigsy chuckled. He thought for a moment and came up with something to distract them from the extraterrestrial's downer train of thought. "Hey, I bet my daughter is better at crawling than your daughter."
The Doctor blinked and looked at him. "What…?"
"Lucy's faster than Alison, I bet," he elaborated. "Wanna have a race?"
"The pudding brain is insinuating that his tiny human is better than you," the Doctor murmured to his daughter. His son babbled back, which his father solved by covering up his mouth with two fingers. "Don't listen to James, sweetie; you have hybrid robustness."
"I take it Jim can see the fact that Aly can't win?"
"One, they are James and Alison, and two, my daughter is better than your daughter and we can prove it." The Time Lord stood and went over towards a clear patch of grass, nice and soft and flat, with plenty of shade and not a lot of people around. He took Alison out of her pouch and placed her on the ground, allowing her to sit up on her own. "Afraid, Local Knowledge?"
"You're on," Rigsy laughed. He brought Lucy over to sit next to Alison and the fathers went about ten feet away. They crouched down and began to call them, trying to get them to crawl their way over.
Instead, the girls simply sat there, wobbling in place before falling over simultaneously. Their fathers' jaws dropped in disbelief as the babies laid there and sputtered.
"Alison Joan Oswald-Smith, you get over here this instant," the Doctor ordered. He was answered with giggling, which he scoffed at in disbelief. "Don't you use that tone of voice with me, young lady! You scoot that nappy over here!" She merely wiggled in place, happy where she was at.
"Come on Lucy, come over to your dad," Rigsy asked gently. When she didn't make an effort to leave her spot either, he sat down in disbelief, completely heartbroken. "…but Luce…"
"It's no use," the Doctor marveled. He too sat down and took James from the papoose to put him on the grass, making the weight on his chest even again before laying down spread-eagle. "I was certain it was going to work."
"They're already rebelling," Rigsy sighed. "Always knew fatherhood wouldn't be easy, but this takes the cake as far as early rebellion." He then watched in silent disbelief as James scooted his way across the grass and laid down between his sister and Lucy. The two girls then rolled themselves over and plopped down on James, the three babies in a big, squishy, sleepy, pile. "Uh… Doctor?"
"Not now, Local Knowledge."
"You sure?"
"Yes, I'm sure."
"Okay." Rigsy drew his knees up and wrapped his arms around them, watching their children with a smile on his face.
