Lucy smiles. So definitely that one, then. She's not quite as chatty and open as the last time they met, nor is she anywhere near as unhinged. If nothing else, jail had a somewhat calming effect on her. Gave her some time to get her mind back together, well, somewhat at least.

"Yes, long time ago. For me, at least. I never got to thank you for that," she answers. Of course, the Master had undone most of it, but not all. "It made things a good deal easier." Not that she'd do it again. She's become a bit more protective of her mind. But it certainly made killing her husband (twice!) a fair deal simpler. And hey, this is actually a person (or entity, anyway) that she could actually admit that to without judgement.

"By the way, I should tell you that you've probably fallen through a rift in space and time and ended up in a different universe," she informs him casually. No biggie. Seems a bit implausible that the first person he'd bump into would be her, but then this whole situation seems a bit far-fetched in general. Actually, her whole life seems a bit implausible at this point, so what can you do?
