Rose rapidly sat up, only to be overcome with nausea again. The Doctor quickly pulled out a needle of red fluid and injected it into Rose's arm. She instantly felt better.
"I'm…pregnant?" asked Rose incredulously. "I thought we weren't compatible."
"I thought so too. But this cheeky madam," he touched the wall of the TARDIS, "changed you."
"How? When?"
The Doctor ran his fingers through his wild hair, and then got a look of recognition on his face.
"The vortex! When you absorbed it, the TARDIS changed you!"
They felt an affirmative nudge in their minds.
Rose smiled. "Doctor, I love you. This will just be another adventure for the Doctor and his companion, Rose."
The Doctor kissed her smartly, then picked her up and brought her to the medical bay. He laid her on an exam table then pulled a machine over.
"Is that an ultrasound?" Rose asked, surprised.
"Of course. Gallifrey had pregnant women too, Rose."
He had her lift her shirt and unbutton the top of her jeans. He squirted goo onto her stomach and then rubbed a wand over her stomach. Rose gasped. A 3D hologram appeared over her stomach. A small baby-shaped blob appeared.
"Wow," Rose gasped.
"About three months gone, you are," said the Doctor, putting away the machine and handing Rose a towel to wipe off the goo.
He placed his hands on Rose's stomach. "Hi darling. I am your daddy. You are a miracle. I can't wait to meet you, baby girl."
Rose's eyes lit up. "I'm having a girl? We're having a girl?"
The Doctor nodded. Rose sat up and hugged the doctor tightly. She then looked at the ceiling.
"Thank you."
A happy hum could be heard as the TARDIS celebrated her owner finally happy.
Suddenly, the Doctor jumped up and ran to a drawer, rummaging through it. He hurried back to Rose, and then fell to one knee.
"Rose Tyler, will you marry me?"
Rose smiled. "Yes, Doctor, I will."
He slid a navy blue ring onto her finger, and then slid a matching one onto his. Rose gasped as the ring melded into her skin, creating a tattoo. She looked to see that the Doctor's ring had done the same.
"What are these?" asked Rose.
"These are Gallifreyian wedding rings. They allow a melding on minds between the couple and, if a fetus is involved, a melding of all the minds. Essentially, I just made you and the baby telepathic."
"Telepathic, huh?" thought Rose.
"Yup," he thought back, popping his 'p'. Rose giggled.
"Another perk of these is that the couple can monitor each other's health statuses. For example, I can tell that you are perfectly healthy, but that you are slightly dehydrated due to the vomiting. Personally, I think the fact that you've only had morning sickness once is great for you, since morning sickness usually backs off at the end of the first semester. And I can make something to help you with it if it persists." He kissed her.
Rose looked deeply into the new link and giggled. "And I can tell that my Time Lord is hungry."
The Doctor's stomach chose that moment to growl loudly.
"So do these rings mean we are actually married?" asked Rose as they walked to the kitchen.
"Yep. A melding of minds is the deepest level of a relationship."
"So you know what this means?"
"What?"
"We have to go home and tell mum."
The Doctor groaned. "I've just lost my appetite."
