Description of Imogen: she's 5.5ft with long brown hair, fair skin and violet eyes. As of Platform One she wears a golden locket engraved with Gallifreyan. Imogen looks similar to Emily Rudd.

Imogen didn't continue her travels with the Doctor straight away as she wanted to spend a little time with her mother. On Boxing Day they went to the Oswald's which Imogen enjoyed immensely. After all, the last time she'd seen both Cousin Clara and Uncle Dave it was at Aunt Ellie's funeral. It also seemed the Clara still had not been able to successfully bake a soufflé without burning it.

A couple of days later a letter came through the post for Imogen. The writing on the envelope was the same as the previous one which told her that it was from R.S. Imogen held the envelope thinking about the last one she'd gotten at the café in Cardiff.

~flashback~

My dearest Gen

If you are reading this then I know you're in the bathroom of the restaurant you and the Doctor are having dinner with Margaret. I realise that my previous letter to you was somewhat vague and again I apologise for it. Unfortunately I cannot give you any more information about how I know you or why you're getting these letters from me. I realise that is not what you wanted to hear but you must be patient and I know you can be, you were always far more patient than our mutual friend.

Although I cannot answer your questions, I can tell you this: the extrapolator is dangerous. You have to disconnect it from the TARDIS. If you don't, it will open the Rift and the world will be torn apart.

Now run Gen. RUN!

~end flashback~

Imogen opened the envelope and pulled out the letter. She wondered if this time her questions would be answered or would the letter raise new ones. It was highly likely to be the latter.

My dearest Gen

I hope you've had a wonderful Christmas, with the exception of the Sycorax invading. Please don't panic about what I'm going to tell you. But the changes you've been experiencing is only the beginning. I'm afraid there is still more to come.

Imogen's eyes widened at that "What?"

I know that is not what you expected and I know that right now you must be getting very worried.

"You don't say", Imogen muttered.

You don't need to be, my dearest Imogen. You'll have our mutual friend to help you through it. I know for certain that he will be more than willing to help you. You will still be getting letters from me as well.

As always trust yourself. Trust your instincts

R.S

Imogen sat staring at the letter. She had hoped that her feelings/instincts; saying random stuff; extra titbits of knowledge and seeing Naiyah was going to be the extent of it. What other changes I am to expect? She thought fiddling with the locket around her neck I wonder what the Doctor would say if reads this?

Imogen was broken out of her thoughts when she heard the tell-tale noise of the TARDIS materializing. She quickly grabbed her brown purse stuffing both her phone and letter into it. "Yeah I heard it mum", Imogen said seeing her mother in the hallway as she hurried down the stairs.

"Have fun and be careful", Sarah Jane said hugging her daughter.

"I will", Imogen promised.

Sarah Jane watched from the front door as Imogen practically ran down the path towards the blue box across the road. Moments later, the wheezing noise started up and the TARDIS vanished.

The girls stepped out of the TARDIS and they gaped at what they saw. It was a futuristic city with flying cars zooming to and fro. "It's the year five billion and twenty three… we're in the galaxy M87, and this…this is New Earth", the Doctor said.

"That's just… That's just…" Rose couldn't quite come up with the words to describe what she thought about it.

"Fantastic!" Imogen said laughing happily as she watching the flying vehicles. Just seeing that made her forget her concerns about the letter she'd received.

"I'll never get used to this. Never. Different ground beneath my feet!" Rose jumped up and down excitedly "Different sky. What's that smell?"

The Doctor bends down and pulls some grass up. "Apple grass", he said showing the girls. Imogen took the blades of grass from him and sniffed it.

"Apple grass", she repeated smiling.

"That's beautiful!" Rose said gazing up at the Doctor, smiling "Oh, I love this. Can I just say…" she linked his arm through his "…travelling with you… I love it"

"Same", Imogen agreed. Suddenly she tapped the Doctor's arm and shouted "tag!"

Rose watched as the Doctor chased after the laughing brunette. Although it was rather amusing watching the pair act like children, she couldn't help feel a pang of jealousy at how easily the two seemed to get along. She's still getting used to this new Doctor but Imogen is acting like she's known this version for years instead of a few days.

Imogen shrieked as he caught her, lifting her off her feet and spinning her around. The Doctor lost his balance bringing them both down, Imogen on top of the Time Lord. They both lay there stunned for a moment before bursting out in laughter. "Looks like this new you has rubbish balance", Imogen said getting off him and helped him up.

A bit later…

The trio lay sprawled on the grass, lying on the Doctor's coat. "So, the year five billion…the sun expands, the Earth gets roasted", the Doctor said looking up at the sky.

"That was our first trip", Rose smiled recalling their first trip with the Doctor.

"We had chips", Imogen added.

"Well you two had chips. I didn't because someone kept stealing mine" the Doctor gave Imogen a pointed look.

"You took some of my chips too", Imogen countered.

"Because you took my chips first", the Doctor shot back.

"They looked nicer than mine", Imogen argued.

"They were the same!" the Doctor exclaimed.

Rose shook her head at their argument. "So anyway, planet gone, all rocks and dust, but the human race lives on, spread out across the stars", The Doctor said changing the subject "Soon as the Earth burns up… oh yeah, they get all nostalgic… big revival movement… but then find this place!" The Doctor propped himself up on his elbows to get a better look at the view of the city "Same size as the Earth, same air, same orbit. Lovely. Call goes out, the humans move in"

"What's the city called?" Rose asked.

"New New York", the Doctor replied.

"Oh, come on", Imogen said not believing him.

"It is! It's the city of New New York!" the Doctor pauses, thinking "Strictly speaking, it's the fifteenth New York since the original, so that makes it New New New New New New New New New New New New New New York" Imogen smiled down at him which he notices "What?"

"You're so different", the brunette remarked.

"Still good different?" the Doctor asked hopeful.

"Absolutely", Imogen answered and the Doctor grinned at that.

"Can we go and visit New New York… so good they named it twice?" Rose asked getting up. Imogen stood up as well.

"Well… I thought we might go there first", the Doctor said nodding to a large building in the distance.

"Why, what is it?" Rose asked.

"Some sort of hospital. Green moon on the side. That's the universal symbol for hospitals", the Doctor said shrugging on his coat. He then pulled out his psychic paper "I got this. A message on the psychic paper" the Doctor showed both of them what was written on the paper.

"Someone wants to see you", Imogen said reading it.

"And here I thought we were just sight-seeing. Come on, then. Let's go and buy some grapes", Rose said linking her arm through Imogen's. Imogen took hold of the Doctor's hand and they walked towards the hospital.
