"Well, New Earth was fun," Christina said, sarcastically. The Doctor waggled his finger disapprovingly at her. "Next time we visit New Buckingham Palace, nick something that isn't a pure gold ball of yarn given to the cat-people as a peace treaty from the humans," he tutted. "Come on Doctor? Where's your sense of adventure?" Christina teased. The Doctor growled, and then walked over to the main console screen.

"We are we going now?" Christina asked, changing the subject. "We are going to old London town, 1913. I need to do a bit of shopping. Feel free to walk around." The Doctor pulled a lever on the TARDIS, and it shook wildly.

Christina loved this part. The rumble, the shaking. The adrenaline and the excitement wondering what their new destination would be like.

Alas, the TARDIS stopped to a halt, and the Doctor said, "Err... if you want we can rent a hotel… you know, humans. Sometimes I forget you need sleep. Sleep is good." Christina nodded, suddenly realizing how tired she was running from cat-people with bazookas. They stepped outside and the Doctor told her they'd meet in an hour in front of the TARDIS.

Christina roamed the town, the cold, brisk, autumn wind blowing against her face, which was tinted red from the cold. A school stood proudly in front of her, tall and cathedral-like. Looking around, she was an African-English girl heading towards the East into what seemed like an endless forest.

Recognizing the face, but not knowing where, Christina followed her. She pebbled through the forest, trailing the girl closely behind, when a twig snapped beneath her feet. The girl immediately spun around and called out, "Hello? Anyone there?" she had a definite English accent. The girl shrugged, and kept walking. All of a sudden, Christina knew who the face belonged to.

She ran up to the girl. "'Scuse me," she asked. The girl spun around. "Oh! Hello there!" Christina hesitated, and then said, "Um… are you Martha Jones, companion of the Doctor? TARDIS? Bigger on the inside?"

Martha looked at the pathway ahead, apparently deciding whether to run or answer her question. Then, as if a light bulb went off in her head, she grinned.

"Oh! Did the Doctor cross his own timeline? You're one of his companions, aren't you? Nice to meet you… and you are?" Martha said. Cristina shook her hand. "Lady Christina de Souza. Where's the Doctor?" Martha sighed, then replied, "Well… he sort of forgot… now, he's chattin' up with some blonde." Christina scowled. "Typical."

Martha laughed. "Have you heard of a 'Rose Tyler'? Does she travel with you lot?" Christina questioned. Martha snorted, then said, "Might as well be. I know her." Christina gave Martha an odd look, then said, "Well, Martha. If the Doctor 'forgot', tell him you'll love him and trust me. That'll get his attention." Martha pulled a smile. "Yeah. Thanks, but I better get going. Who knows? Not to be rude, but us talking to each other might create a paradox or the fabric of time destroyed or somethin'. It was nice meeting you."

Christina waved goodbye and headed back to the TARDIS. On her way there, in an alley, she saw the Doctor, Martha's Doctor, kiss a blonde in the corner of the alley and scowled. Suddenly, another Doctor ran up to her. Her Doctor. To his surprise, Christina slapped him, and cried indignantly, "Just like you to be chattin' up with blondes!"
