Jo dashes through GD. Fargo catches up to her in the lobby. She thanks him for a memorable night, which is the wrong word to use since she acted like she forgot all about it a few hours ago, as Fargo points out. Jo blames it on a sleeping pill she took that made her "a bit out of sorts." I'll say! You know what's a bad idea? Taking sleeping pills and drinking a lot. Fargo wants to talk to Jo, but she says she has to go and offers to meet him later at the target range for a talk instead. Fargo assumes this is a date, and Jo doesn't disabuse him of that notion as she runs for the elevator. The doors close just as Zane is running to try to talk to her. Ha ha! Since Jo is gone, Zane turns around and sees Fargo and starts towards him. Fargo assumes he's about to get beaten up for stealing Zane's girlfriend and prepares for battle. "You wanna dance? Let's dance!" he says, showing off the martial arts moves he claims to have learned in tenth grade. Damn. My school barely taught us volleyball, let alone exotic martial arts. Meanwhile, a GD security guard watches this all and decides there's no need to intervene. But Zane doesn't want to fight -- he's worried about Jo's erratic behavior, and asks if Fargo noticed anything odd when he just spoke to her. Fargo says she asked him out. Zane finds Fargo so unthreatening to his relationship with Jo that he doesn't get angry, just says it proves that she's been acting strangely. That's kind of insulting to Fargo, but he just says that he felt a real connection with Jo and thinks her feelings for him are sincere.
Jo is back at Henry's garage, where he has finally come up with a use for all three of the stolen items: they're all used in experiments on DNA manipulation. So the out-of-character Jo was not Jo at all, but someone who manipulated her DNA to look like Jo. I think. [Then why were they still stealing stuff when they already looked like Jo? - Z] Henry rather insultingly asks who would want Jo's DNA with all of the awesome Eureka DNA to choose from. Jo has a pretty good idea: "someone who thinks I'm perfect." So that rules out Zane.
