I'll have to double check on the date. This is going to occur six-to-twelve months after the SOS-Con - sometime between when they take delivery of their Blackbird and when they've discovered that they won't be able to implant Gina as the Midnight's AI. And if all he has to worry about is flirting, that'll be when Gina steps in. What she'll do, I'm not sure, but I know that she's smart enough to figure something out.
And I have no idea why Benjamin would call her Washu. If she did anything to remind him about the crazy little scientist, he'll keep his yap shut unless it was something really... big. At that point, he wouldn't call her Washu outright, but instead he'll say something like, "The hell? Did your biomod happen to take some cues from that mad scientist in Tenchi Muyo?"
It'll still get a reaction out of her, I'm sure, but it's a more fun and roundabout way of doing it.
