A wry grin, she knows she's trying to help. "I've got the not-dying thing mastered, thanks," and how. She gestured broadly.

"It's everything else. My universe doesn't have magic. I promised the most important person to me not to fight, and I couldn't even do psychic stuff without his help, and others literally goin' into my brain to sort it out like radio waves or something, and even now, I can't reach him back, so I don't know how I could touch anyone else like that, yeah?"

She rubbed her face with a hand. It was all so stupid. Mickey became a top Torchwood agent, Rose's entire career was defender of Earth and other dimensions, but stick her in a classroom; and she couldn't feel more useless. Exactly like that sixteen year old, dying inside, begging anyone at all to save her, even when it led to absolute disaster because the first bloke to come along to do that only made it worse. And what if Rose made the darkness worse? At least if she could follow the chain of Bad Wolf, the message to herself, she'd have some more direction again, just like her stepping stones across universes.
