Set just after The Lazarus Experiment.

Martha had watched as the Doctor and Rose laughed their way through the pre-drinks party, holding hands and joking with each other for about an hour.

She had watched as the Doctor's hands had wound their way around Rose's waist, how he brushed crumbs from the corner of her mouth, how he watched her, smiling as she mingled with people in the crowd.

Martha watched at first, jealous at their flirtatious ways. The way they would childishly tickle each other, standing against a wall in the corner of the room. Or the way in which they would try to trip each other up and pull faces when they thought no-one was watching.

But over the night, Martha had come to realise that however much she tried to get the Doctor's attention or flirt with him it wouldn't work. Because the Doctor had eyes for only one person.

Rose.

And Rose obviously felt the same.

Martha thought back to the conversation her and Rose had had earlier on in the evening. How Rose had allowed Martha to go ahead and confess her feelings for the Doctor despite the fact that she too obviously had the same feelings for him.

Martha's heart almost broke when she thought of how Rose must have felt when Martha came onto the scene, just barging in unannounced.

She felt so utterly sorry for her.

Now the trio walked back to the TARDIS all silently contemplating the night's events.

Rose looked strange. Her heel had broken whilst running in the cathedral, so the Doctor had leant her his converse trainers to walk back to Martha's flat in. He was walking in bare feet, what a sight they must have looked to passersby thought Martha.

Martha chuckled to herself as she rummaged around in her bag for her keys.

Rose walked through the TARDIS doors and head for her bedroom, she was freezing and desperately wanted to change into her warm pyjamas and cosy socks. She had left the Doctor and Martha outside the doors, not wishing to get in their way.

The night had been a strange one, apart from all of the action and all of the running, she had never felt as close to the Doctor as she did tonight. It was a good feeling but she felt a pang of guilt when she saw Martha, knowing that she and the Doctor had feelings for each other.

Sighing she began to remove her clothes and take down her hair.

Martha went to walk through the TARDIS doors before stopping in front of them and turning to the Doctor, blocking his path.

The Doctor bumped into Martha and looked down at her confused. He had obviously been watching after Rose who had walked through the doors ahead of them moments ago.

"What's wrong Martha?" he asked, looking at her concernedly.

Martha took his hand slowly, she could feel the Doctor squirming slightly in her grasp, but still gazing at her intently.

"You like her don't you?" said Martha staring directly into his eyes.

The Doctor gulped, his eyes darting this way and that, and ran a hand through is hair.

"Um.....well yes of course I do....I mean....she's my friend......" he spluttered.

Martha smiled knowingly.

"I think you know as well as I do Doctor, that you think of her as a bit more than just your friend."

The Doctor placed his fingers over his eyes and pinched the bridge of his nose, scrunching up his face as he did so.

"Oh I don't know," he said.

Martha removed her hand from his and placed it onto his shoulder.

"You should tell her," she said, seeing right through his mumbling.

He took his hand away and looked at her.

"I can't," he said quietly, "I-I just can't."

Martha sighed, continuing to smile.

"Tell her Doctor."

The Doctor gulped and glanced away uncomfortably.

"But what if she doesn't feel the same?" he asked, his mouth pinched tensely.

Martha beamed and hugged him tenderly.

"She does Doctor, she really does."

Rose walked into the console room expecting to see the Doctor and Martha there. Surprised that they weren't, she suddenly heard muffled voices from outside the door.

They're still out there she thought to herself, rolling her eyes. Hoping she wasn't going to walk out onto anything awkward, Rose tugged open the door.

She stopped abruptly when she caught sight of the Doctor and Martha hugging.

"Sorry," she said holding back slight tears of jealousy, "I didn't mean to-"

"No, it's OK," said Martha, beaming at her, pulling away from the Doctor. "I was just saying goodbye."

"Goodbye?" said Rose aghast, "Why where are you going?"

"I'm staying here," said Martha, "I don't want to be just a passenger.....y'know someone you take along just for a treat anymore.....anyway....I'm just getting in your way....."

Rose tilted her head looking at Martha confusedly. What had happened between them, thought Rose glancing between Martha and the Doctor.

Walking up to Martha, Rose took her arm.

"Please don't go," she said sincerely, "stay with us, you're more than just a passenger, you're our friend. She should stay shouldn't she Doctor?"

The Doctor looked anxious for a moment before his face cracked into a wide grin.

"Of course she should. Come on."

Martha squealed in delight as she headed back towards the TARDIS, Rose stepping in first.

But slowly she turned towards the Doctor.

"Thank you," said Martha looking up at him in delight. They hugged.

"Well, you were never just a passenger were you," he said grinning.

His face softening he spoke again, this time in just a whisper.

"Thank you," he said earnestly, nodding in the direction Rose had just left in.

Martha smiled at him, knowing that the two of them would be really happy together....once he's told her that is.

I know that was a bit of a cop-out but I doubted Martha would be blind and would blatantly see how much the Doctor liked Rose eventually. Plus I wanted it to get a bit more fluffy Ten/Rose soon and Martha was just getting in the way.....I was going to ditch her....but decided against it last minute.

Anyway...I hope you like this chapter.....if you do please review. Thanks!
