Nbeke, you're in one of Master Chef's labs. Probably checking on the drug output or something, but what did you tell her and why is she so happy to see you? Either way, she's got something important she's putting together, which is why the place is such a disaster area. She has a really cute biting-her-lip crossed eyes look when she's measuring the whatever the fuck it is. "Don't touch that, boss!"
She's not getting uppity, she's trying to save you from doing something stupid. What happened last time someone didn't listen to her?
In case you forgot, here's her about-to-pop self, moving around the tight lab with some effort.
I've no idea where her little replacement has gotten off to- probably messing around in the hard lab, right? Maybe they're getting better if Master Chef is fine leaving them alone. You seen 'em?
