"Doctor, what happened to Jack?"

The Doctor froze at the controls. He was sure the question would come up at some point but he had imagined it wouldn't be so… out of the blue.

"The Game Station," he answered. "The Daleks and the Bad Wolf—"

"Bad Wolf?" Rose broke in.

"—company," he finished hurriedly. "The Bad Wolf Company; The ones who owned the Game Station."

"No, there was something else. Something about Bad Wolf." Rose ran her fingers through her hair. "You can't believe how frustrating it is having a hole in your memory on such an important day."

"Why was it so important? Don't we defeat the Daleks every day?" The Doctor prodded gently. It was more than Jack now. He had to keep away from the subject of the Bad Wolf or it could be dangerous for Rose.

"Well, that's true." Rose smiled. "It was the day you regenerated, though. Isn't that important?"

"Eh, Timelords get used to regenerations. Big, universe-changing events are more important to us than the last time we got a makeover."

Rose laughed and smiled at him. "Well, it's important to me." The Doctor tried not to show any emotion at her comment. Why was it important? Because of Jack? The memory loss? Did she have some notion of the enormous change she had undergone on the Game Station? Or… was it something much more human? Did she miss him? The old battered war-worn Doctor that had first taken her hand—did she wish he was still piloting the TARDIS? The Doctor looked down at his hands, thinner and paler than before. He could remember when he was changing, they glowed with golden energy, time energy, like Rose's eyes had blazed as the Bad Wolf.

"Doctor?"

He looked up pasting a grin on almost immediately. "Yes, hello?"

Rose's forehead crinkled in concern. "Are you alright? You got much too serious for a moment."

"I'm brilliant. Never better." He pushed off from the console and began pressing buttons. "Where to now, Rose Tyler?"

Rose smiled with her tongue in her teeth. She loved when he said her name. "Anywhere!"
