I dunno, they've kind of dropped the ball on the "lookalike scenarios".
When Starr left and Kiki arrived, no one mentioned the resemblance. When Todd left and Franco arrived, no one mentioned the resemblance either. But when John McBain left and Dr. Silas Clay arrived, everyone flipped out about his resemblance to Caleb Morley the "would-be vampire". This, despite no one mentioning that John McBain had looked like Caleb, too. Turned out Caleb was Silas's twin brother, I believe, and they explained away the whole vampire thing as Caleb being insane. When Silas was murdered and Hamilton Finn showed up, one or two random characters spoke of the resemblance to Silas, but not the ones that should have mattered. Easton (as Finn) has yet to share a scene with either of the Ninas, so we missed seeing her do a double take when meeting him. Anna interacted with McBain a lot, and Sam was in love with Silas, but neither woman has mentioned the resemblances. Kiki never mentioned how much her late father looked like Dr. Finn. Dr. Obrecht has dealt with all three of Easton's characters and she hasn't noticed. It's all kind of sloppy.
So Lulu's in a stall in the ladies room and overhears Dr. O and Sasha discussing how Sasha is not Nina's daughter, and I'm laughing mighty hard. She wisely pulls her feet up so no one sees her feet under the stall doors, and she's sitting there with a wide-open mouth like Lucy Ricardo in one of her schemes. I know it was supposed to be a dramatic turning point in the plot, but I like that they made it kind of funny rather than the typical revelation. Maybe having that English Teacher Hottie* after her has made Lulu loosen up a bit.
