Filler while I'm trying to think about how to further the story, and this might add some insight. I've extended the timeline for human nature from 3 to 6 months (as Martha's trying to track down the family as well as make sure everything's arranged.

February 21 1913, somewhere outside of Farrington, England.

John Smith was taking a walk. This in itself was unusual for him, as while he did occasionally enjoy a walk on an exceptionally beautiful day, this wasn't one of them.

For whatever reason, he felt compelled to walk out into the snow and the rain, and get himself lost. He shivered a little and pulled his damp overcoat closer, trying to pull what warmth was left into his body.

He hoped that there was some place nearby where he could get directions back to his flat and dry off a little. He frowned as a soggy page from some forgotten book hit him in the face.

He stifled a curse, as his mother, bless her, had always hated cursing, a trait she had passed on to him by force. Once Smith had torn the soggy parchment (which was quickly dissolving into mulch at this point) off his face, he realized that he had gotten even more lost than he had been before, and to make matters worse, he could see the night starting to creep back into the sky.

In the distance, he noticed two figures talking in the middle of the road. Smith sincerely hoped that these two were just fellow travelers, and not a pair of highwaymen.

When he got closer he saw that they were no longer talking, but kissing each other passionately. To further disturb his prudish Victorian sensibilities (also from his mother) he quickly realized that they were both men.

Smith made a disgusted clicking noise with his tongue, and continued to walk by, more concerned with getting someplace warm and dry than his principals at the moment, when he saw something out of the corner of his eye.

He did a quick double take over his shoulder, just to confirm what he'd seen, then he picked up the pace and ran.

1941, (month unknown sometime during the blitz) London, England

The bombs were falling, and there were only a few people left on the street. most of them were there because they had been caught unawares when the sirens sounded, but even the ones who thought they were being clever by stealing food while people were cowering in their homemade bomb shelters had enough sense to run. There was only one man who was casually strolling through the street, and he had long sense given up caring about his life.

There was an earsplitting noise as the next bomb fell, it only lasted for a few seconds, and wasn't like anything else he'd heard. The loud keening sound made him cover his ears, although he fared much better than the people around him, who were doubled over in pain.

This distraction almost got them all killed, as a bomb hit seconds after they'd recovered.

Everyone else present believed that the noise was the sound of a bomb hitting maximum velocity shortly before hitting the ground. The man who, for one of the first times in his life, was one of the few people who wasn't running, knew otherwise; but chose to ignore it.

Later he tried not to think about how similar it sounded to someone or something crying

Somewhere in time and space

A man with black eye watched his ship, the chill that went down his spine helped him decide against staying any longer.

England! I don't even care anymore.

He saw it, just as he went under. The nurse. She was awful, horrible her eyes! He'd thought he'd never see them again…

Poor Peri…. If he'd though to check sooner he could have avoided this…. As he started to close the door behind him, he noticed a small child standing in the middle of the rubble. The child in question, a rosy cheeked little girl of about seven years old slowly turned her head to face him, and smiled. He tried to remain calm for Peri, but he closed the door and tried to escape as quickly as possible

I'm sorry that some of the earlier doctors may be a little out of character, The ninth, tenth and eleventh were the ones that got me into Doctor who, and I haven't seen many of the original series.
