A/N: So I had headcanon Tentoo/Rose twins for a while now but I only just realized how funny this exchange would be XD

Disclaimer: I don't own Rose, Tentoo, or any characters that appear in the BBC series Doctor Who. I do own my OC doctor but he probably won't appear much. I do own the twins, or I will when they're born. I also don't own the song this is titled after, which is from "The Man of Le Mancha" Broadway Musical. Fantastic song, check it out. Ditto with the song this chapter ia titled after, "Counting Stars"

The Doctor, stop running? Settle down long enough to get married? Start a family? And keep them safe? Impossible. For the longest time that had been the ruling, hands down.

And yet here was the Metacrisis Doctor, sitting in a twenty-first century Earth hospital with his wife, his Rose, staring wide-eyed at the screen of an ultrasound machine, on which was the first picture of their baby.

And there was Rose, smiling, her brightest smile, the smile that had mesmerized him. Here he was, with the love of his life, his one life that he got to spend with her. Her and their baby. He was going to be a dad, and Rose was going to be the best mum in the universe.

"Now here's something interesting," Dr. Morgan, who was operating the machine, said. "Do you see this here?" He pointed to a white object in the screen.

"Yeah," Rose spoke for them both, as her Doctor was still speechless. It was a rare occurrence that she was taking advantage of.

"That's the baby's heart," explained Dr. Morgan.

Of course it is, I'm not stupid, thought the Doctor, but he didn't say that out loud.

"You see this?" Dr. Morgan continued.

The Doctor looked, then paled. Oh. "Is, uh, is that... Is that another one?"

A million thoughts rushed through his head in a second. Of course. He had been stupid. Of course his baby would have two hearts. He had assumed the human DNA would override the Time Lord, as he was only half Time Lord and the baby would only be a quarter. What if someone in the hospital found out? What would happen to their baby? But no, he shouldn't worry, the baby's grandad was head of Torchwood, nothing could happen to it there. Besides, if anyone of anything tried to get in between this baby and his or her parents, they would have to answer to the Oncoming Storm and the Defender of Earth.

He and Rose exchanged a glance.

Rose's laugh was so convincing, if he hadn't known her so well he wouldn't have suspected anything in the galaxy would worry her. "Are you saying our baby has two hearts?"

Dr. Morgan replied as expected. "Oh no, don't be silly Mrs. Tyler. Your baby is as normal as any in this hospital."

The Doctor joined in with Rose's laugh, privately wondering how he could have thought any child of his would be normal.

And then the unexpected bit came: "You're having twins."

The Doctor's jaw fell as heavily as the shocked silence.

"We're doing what now?" Rose asked.

He stood and made his way to the viewing screen, pulling his glasses out of the inner pocket of his blue suit. He squinted at the screen for about a minute, then, after judging that the hearts did indeed belong to two seperate bodies, opened his mouth and said, "We're having twins."

He turned to his wife in a daze, as repeated, "We're having twins." Then his face broke out into a beam and exclaimed again, "We're having twins!"

He and Rose laughed for real this time, shrieking with joy.

"We wanted one and now we've got two!" The Doctor hugged Rose, "How human is that?!"

A/N: So that was fun :D. Next I'm planning some cute fluff over baby names. Suggestions would be fantastic! In fact please please leave a prompt, either by review or PM. It doesn't have to be from when the twins were babies, I'm pretty sure this isn't going to be in order.
