There's no glimmer of recognition on Lucy's face at all.

"Oh. You mean the shit that happened with Jenny? Yeah, I was safe. I was asleep for the first half of it, actually. When I woke up, the whole ship was lurching." By which she means, Nyuu was awake for the first half of it, hit her head during one of the lurches, causing her (Lucy) to awaken and take control of their body.

She tilts her head. "Have we met? Or... Have you met Nyuu?" she asks. Is that why this person (bot) is speaking to her in a rather familiar manner?
