A/N: I am doing this one for my friend's birthday. She said she wanted to do a Doctor/OC like this but couldn't think of an OC. So, I told her I might write it for her birthday. Colleen is my OC, but the idea is hers. I'm only writing it for her. Lol. So, MaKayla, happy birthday! You better be glad I love you!


Nothing compared to that feeling. The fear. The anticipation. The love. All bundled into one. All that as she stared at the small white stick in her hand. One that changed everything. She couldn't believe it.

"Rose?" she called, her eyes not leaving it.

"Yeah?" the young, blonde Londoner asked, opening the door to the small bathroom.

"Where is the Doctor?" the woman with the long black hair asked, looking at her.

"He's in town," She replied, confused. "Mum dragged him with her."

When her eyes landed on the small stick, realization hit her.

"You're pregnant, aren't you?" she asked.

The other woman just nodded.

"When are ya going to tell him?" Rose Tyler asked her friend as the both of them made their way to the living room.

"I don't know," She replied as she sat down. "I just don't know if I can tell him. You know how I am. I don't age and I stay the same. He regenerates."

"You're worried about how your dad will take this, aren't you?" Rose asked her, smiling. "Colleen Antonia Harkness is worried for once."

Colleen looked at her, "Worried doesn't cover it, Rose. When you two found the two of us, Daddy had only just found me again. Now, I'm here, pregnant with the Doctor's kid. In case you didn't notice, Daddy is more protective of me now than ever."

The blonde haired young woman rolled her eyes, "Look, Jack might go berserk on him, but, there's nothing to worry about."

"Anyways, where do you want to go next?" Colleen asked, her blue-green eyes light.

"How about we tell him Barcelona?" Rose asked, smiling. "He never did take us to Barcelona."

"You're right," she replied, laughing as the Doctor and Jackie Tyler walked in. "Dogs with no noses!"

The Doctor carrying several huge bags.

"Mum, did you drag him with you so he could carry those for you?" Rose asked, laughing as she watched the Time Lord drop the bags and sit next to Captain Jack Harkness's daughter.

"Colleen, would you please come here?" Jackie asked, grabbing a bag and heading off to Rose's room.

Colleen was confused but stood and did so.

"What do ya need?" she asked, standing in the doorway.

"Well, while the Doctor was babbling on, I got you some new clothes," she replied. "At least some you can wear in this time. Everyone avoids you with that armor."

"Hey, it's saved me plenty of time," Colleen argued halfheartedly.

"It may do very well on another planet or in another time, but not here," she replied before handing her some clothes. "Here. Try those on. I'll get Rose."

Jackie Tyler walked out of the room and shut the door, leaving Colleen to try the clothes.

Looking at the clothes, Colleen rolled her eyes, "Rose, I'm gonna kill Jackie."

A few moments later, the woman called that she was done.

Jackie and Rose Tyler walked into the room.

"So, what do you think?" Colleen asked, crossing her arms over her chest. "'Cause I feel naked without the armor."

"You look…" Rose started, not wanting to say it.

"From this time," Jackie commented.

"Different?" Rose finished.

"I'll say this, I'm only gonna wear these when I'm here on Earth in this time," she muttered. "Got it?"

"Whatever," Jackie told her, waving it off before walking out of the room.

Rose looked to her friend, "How late are you exactly?"

"Let's see, I haven't thought about it," She said, thinking. "I believe about three months. Why?"

"Because I can see a slight bulge," Rose replied, grinning. "If Mum notices it, she'll ask about it. And you know he'll hear it, too."

"Thanks a lot, Rose," She said sarcastically. "You have a hoodie or something?"

Rose just laughed, "Yeah," She said, grabbing a hoodie from her closet. "Here."

Colleen took the hoodie, muttering her thanks, before pulling it on.

"Can you still see it?" She asked, hopeful.

Rose shook her head, "No," She replied.

"Can we hurry and talk to the Doctor about Barcelona?" she asked, smiling a little. "No offense, but you're mum scares me. I faced the Daleks and was exterminated by them and she still scares me."

Rose just laughed, "I'll let you change back," She told her. "Because knowing him, he'll jump at it."

Colleen nodded, smiling, "Thanks."

"No problem," the younger woman replied, smiling before she walked out of the room and closed the door behind her.

Colleen sighed before changing back into her normal clothes. The shin guards that rose above the top of her knees by four inches and shielded the top of her feet, the arm guards that were flush with her elbows and covered the back of her hands, the slightly loose black pants, black long sleeved shirt, and her WWII RAF greatcoat. She left the greatcoat open, just like her father always did. Or still, whatever term you want to use.

She pulled her black hair up in a bun, no stray hairs at all.

She grabbed the clothes and folded them one by one, putting them back in the shopping bag. Grabbing it, she made her way back out with the others.

"You ready, Colleen?" the Doctor asked, grinning.

Colleen nodded, grinning, "Yeah."

"Well, we'll be off then," he told them before heading out towards the TARDIS.

Followed by Jackie, Rose, and Colleen.

Colleen and the Doctor walked into the TARDIS. Rose outside, hugging her mom.

"Rose, be careful," She told her.

"I will Mum," the blonde Londoner replied, smiling. "Besides, Colleen will make sure of it."

Jackie Tyler nodded before releasing her daughter from the hug. Rose smiled at her before walking onto the TARDIS. Closing the door behind her, she made her way up to the console.

"Are we ready?" Rose asked, smiling.

"If you are," Colleen said, returning the smile.

"Well, Allons-y!" the Doctor shouted, grinning before the TARDIS began to shake as it dematerialized.
