"That or a raid on the kitchens that you'll remain totally ignorant and innocent of," Cosima says, pseudo-chipper. "Thanks."

She takes a sip, then says, "I always feel like I'm talking about myself. I just hope you know - I don't ask about personal stuff because it seems like you'd be uncomfortable, not because I don't care. And now..." She'd been about to say now that Ruby's gone, but plows through, "now it's just us, I just wanted to say. That."

It's genuine enough, but Cosima's also found herself in a bit of a conversational cul-de-sac. She takes a slightly longer drink.
