Rosalind was, really, what had changed her mind. Because like hell she was going to sit back and let her sister die a second time. And once she'd decided that, then trying to stop people from finding a workaround for Zack ... it was hypocritical, and sort of pointless to boot. Fuck the timelines.

She tried to remember exactly what Tseng had requested.

"What Zack knows," she said, "and what he's put together as guesswork, even if it's wrong. Where in the timeline he is, definitively and not just our best guess. It'd be great if we could know what's changed, from his reality to ours -- that Zack never went to boarding school, so little things could be changing already, but he wouldn't know what those are."

She lifted her shoulders. "The more ammunition Tseng has, the likelier he can get through to Zack's Tseng, when the time comes. And that means we might have the full operational weight of the Turks behind whatever we're trying to do."

Barring herself. She was still at the Academy when everything happened.
