They reached what she called the TARDIS, and she explained why it was larger on the inside and moved around a console in the middle of the room. When she and Ianto next stepped outside, they found themselves in a London that wasn't London. Ianto looked around, and though he seemed perfectly calm, his eyes were larger than usual, and his lips wore a small frown of distaste. The women didn't wear many clothes, which was utterly shameful. It didn't take him long to like it, however.

They didn't stay in the next world for long, just long enough for Ianto to get some clothes and Romana to poke around a little. "You might want to give these computers a try," she suggested. "I think you'd be rather good at them."

They fell into a sort of routine. Romana didn't seem to need much sleep, if she got any at all, and Ianto would sometimes accompany her outside or would prepare some tea and sit in her library. He had since discovered that the TARDIS was even larger than he initially thought, with the library alone taking up almost as much space as a small palace. She also had several computers from different eras and worlds, and when he felt more secure of his position with her, he began familiarizing himself with the different machines.

"How would you feel," Romana said from over his shoulder one day, "if we took on a third?"

After the first jump of surprise - he hadn't known she was in the library - he shrugged. "It's up to you, ma'am. Not my place to say."

She wrinkled her brow at the "ma'am;" she hadn't been able to get him to call her by her name. "Oh, stop behaving like a long-suffering servant. I'm serious. You live here as well. I want your opinion."

He looked away from the computer monitor and studied her. He couldn't tell for sure, but sometimes he thought she looked thinner and more sallow than when they had first met. "Would it help you in your purpose, ma'am?"

She nodded. "I suspect so, if my theory proves correct."

He turned back to the screen. "Then by all means." He looked at the monitor, but his thoughts couldn't focus on it. "And let me get you some tea while you're here."

When he returned, he found her sitting in the chair beside his. They drank in companionable silence for a few minutes, and then she said. "There are a few problems we might have with the new person." Seeing Ianto's expectant look, she elaborated. "Firstly, we have to find her. Secondly, she may not seem... right at the moment. She may be a little trying on the nerves. But time seems to be converging on her. All throughout the universe, events seem to be growing around this one woman. In every universe. She's like you, actually. In every universe I've been to, there's always been a Ianto Jones."

"Really?" She had mentioned his being a constant when he had first arrived, but it was only after he had traveled to so many universes that he was beginning to appreciate the fact. Romana smiled, and he couldn't help but compare her to Yvonne. Romana seemed to win on all fronts. Kind, generous, organized, intelligent, and able to clean up after herself. He trusted her judgement, even if it meant his own discomfort. "So who is this person we're supposed to find?"

Romana smiled. "Donna Noble."
