He led her through a long and winding path, past trees and bushes. All of it blurred into one as Rose began to lose interest.

"Doctor, how long until we actually get there?" She panted, her limbs were starting to tire, and the events of the day had drained what energy she had left.

"Nearly there, promise." The Doctor called over his shoulder, the adrenaline pulsed through him, egging him on. A few moments later, he let go of Rose's hand as he apparently spotted his target.

"What are we looking for?" Rose asked as she panted for breath. The Doctor motioned a finger to his lips, and she rolled her eyes. He knelt down beside a small pile of rocks in the shade of a tree. She watched him with interest as he dismantled the pile of stones.

"Doctor, what are you doing?" Settling down beside him, she whispered into his ear.

"Looking for something…" Rose sighed at him, wishing he would stop the whole mysterious thing. Minutes went past as he looked under different piles of rocks, searching the through the undergrowth.

"Look! Rose, it's there!" The Doctor's eyes sparkled as he cupped something in his hands, bringing it up to his face.

"What is it?" She sat up straighter, peering into his hands. Settled in the centre of them, was a small yellow creature. It was covered in thick fur, and looked suspiciously like a mouse.

"It's the last of it's kind….well, one of the last. It's similar to a hamster."

"Looks more like a mouse to me." She said softly as she tentatively reached out a finger and stroked it's back. Rose smiled as she felt the fur covered body press itself against her hand.

"It behaves more like a hamster."

"Well, what are you gonna do with it?" Exhaling slowly, the Doctor placed the creature into Rose's hands.

"I'm…going to try and duplicate it. Make more of them." Rose's eyes flicked upwards and she regarded him.

"Are you sure you wanna try that?" The Doctor raised an eyebrow, his russet eyes filling uncertainty.

"I have the ability to do it, am I not supposed to use it?" They looked at each other for a moment, before Rose nodded.

"Sorry. Go ahead." The Doctor shook himself slightly, and knelt directly in front of Rose.

"Um….o.k, Rose, you hold him, and I'll…I'll try it." She gingerly took the little animal in her hands, and watched the Doctor as he exhaled a long, slow breath. Silence settled over them as the Doctor stared intently at the creature in Rose's hands. For the sake of things he decided to call him Martin.

"You alright?" Rose said in a hushed tone. The Doctor didn't answer her, just sat with a blank look in his eyes, that quite frankly, unsettled her.

A while went by before something actually happened, Martin had gone to sleep in his new nest by then. A small rustle by Rose's right hand side caused her to jump, and she protectively sheltered the creature by cupping her hands.

"It's alright." The Doctor muttered, and she relaxed slightly, yet still didn't open her hands. Sitting on the uncomfortable undergrowth, she gasped at the sight that fell upon her eyes.

A small creature trod nervously into the open clearing, shaking it's fur back. It was almost identical to Martin, except with a light blue stripe following it's spine. Rose laughed in disbelief as it scratched at the ground, burying it's nose into the small holes it had made.

"Doctor….did you…did you make him?" Her eyes switched from him to the new little one that was now curled up by her thigh. Blearily, the Doctor opened one eye.

"Her. It's a girl." Rose cooed at her, opening her makeshift shelter for Martin to see. He squealed and Rose set him down on the damp Earth beside the new girl. Rose decided to call her Mary.

"Doctor, I can't believe you did that." She murmured as Mary and her new friend pawed at each other timidly.

"I think he likes her." The Doctor grinned as he opened his eyes, and shook himself out of the trance he had been in.

"Yeah…you feeling alright?" She reached over to place a hand over his. He was looking unusually pale.

"I'm fine. It took a lot out of me…I just need practice, that's all. I'll be able to create things faster once I get the hang of it."

"Can I watch you? Can I see you create something?" Rose said nervously, and the Doctor cocked his head to one side.

"You…you just did."

"No, I saw you sitting there looking all scary, then Mary popped out of the bush-"

"Who's Mary?"

"The mouse like thing-"

"Hamster like thing."

"It doesn't matter." Rose frowned at him, and he grinned at her.

"So....can I watch?" The Doctor fidgeted uncomfortably under her gaze.

"I don't...I don't think you'll stomach it, Rose." He said carefully, choosing instead to focus on Martin and his new friend cuddled up side by side. Rose opened and closed her mouth three times before actually speaking.

"W...Why?" The Doctor sighed.

"I have to create everything in stages, Rose. The skeletal system has to go first of course. Then I have to create the internal organs, like the heart and such. I know what you're like around all of those surgery shows. I just think seeing the heart and stomach and everything else being formed isn't your cup of tea."

"So...you see the organs...like...being made? You see them?" Her nose wrinkled up in distaste.

"Yes. That's why I formed her in the bush. So you couldn't watch it. See, I do think of you." The Doctor smiled, and Rose leaned forwards, wrapping him up into a hug.

"M'proud of you, Doctor. Aren't you gonna make more of them though? Mary and him can't repopulate the entire species." She said as she pulled back.

"Well, they give birth in swarms. They can have up to thirty babies at a time. And the pregnancy only lasts for about three weeks." Rose nodded, considering this.

"They'll be fine then."

"Yeah....I think we should leave them both...I think Martin may have just pulled." Rose laughed and allowed the Doctor to pull her up. They walked back through the forest, both absurdly pleased. Rose felt triumphant in a way. She knew that he could use this for good, Sarah Jane was just being silly. It had been less than an hour, and the Doctor had already saved one species. Sure they were only small, but he said he could achieve bigger and better things in time. And she believed in him.

"So....what's your next act, oh mighty Time Lord?" Rose grinned as she leaned against the TARDIS. The Doctor raised and eyebrow at her.

"Making a cup of tea, I think. I'm knackered." Rose rolled her eyes and followed him inside. As she closed the door behind her, she stopped.

"Hang on, Doctor? Who's Martin?"

Hope you enjoyed my vague attempt at humour there lol. Hope you liked xx
