Journey to the End.

Romana watched Martha as the young woman, well as a human she was younger than Romana, ate her breakfast happily. After watching those images and the way Rose Tyler had been, both girls had vowed that they would never do half the things the girl had done.

Romana hadn't thought much of Rose when she'd first heard about the girl and her escapades, but watching the images as she laughed at other people, put her mother and supposed boyfriend down, brought men into the TARDIS to make the Doctor jealous. On top of that, ripping open the console to gain access to the Time vortex, to say nothing about the way she'd saved her father.

Martha had heard stories about people who once they saw something better than what they already had, just dumped the thing they'd had in the past. When it was over, they went back again. She could see that happen with Mickey Smith, Rose's unfortunate boyfriend.

She remembered the discussion they'd had afterwards.

Romana was shaken from her thoughts when the TARDIS lurched. Rushing to the console room, she found the Doctor and Jack arguing, " What's wrong ?"

" Jack touched a control by mistake and the TARDIS took off. I told you, she's still not used to your immortality."

The TARDIS stopped before Jack could come up with an excuse or a witty comeback and the Doctor and Romana studied the console readings.

Both of them looked grave.

" What is it ?" Martha asked concerned, not liking her new extended family's grim faces.

Romana looked up, almost as if she'd forgotten the two humans were in the room.

" We've landed, in the year one hundred trillion."

Jack's jaw dropped in shock, he looked a lot like a demented goldfish. Martha, on the other hand, was ignorant.

" So, what's wrong ?"

The Doctor shook himself out of his stupor, " We're at the end of the universe."

He looked grave, " We should go, the Time lords never came this far." He looked directly into Romana's eyes and suddenly, both of them grinned.

" As if," Romana's retort made them realise the Doctor and her were meant for one another, and Martha of course.

What they didn't know was that the worse was to come.
