“Did you ever meet Isobel?” Not as much of a non sequitur as it initially appears - she remembers when Katherine had briefly mistaken her, remembers meeting Isobel herself in person. How strangely surreal it had been; how Isobel had tried and failed to compel her, and how very polite she'd been about it afterwards. “It's a bit strange, isn't it, that phenomena.”

Like people can't even be sure that their faces are their own, here; she supposes fair enough, given that hers isn't, really. Not any more.
