Carter has been given just enough straws to make a flimsy pole that can't reach the button and bends in on itself when he tries to make it. Julia the assistant is watching him suffer when Jo enters, asking if she can talk to Carter. What! Why would she tell Allison and Henry that she's perfectly capable of investigating the thefts that she herself might have committed and then go running to Carter like that? What happened to Jo's confidence? It's because she's dating Zane, I'll bet. Julia says the rules state that Carter can have no outside contact during his test. Carter, meanwhile, has lost his straw pole and is moaning about how much this test sucks. "I've gotta go back to the beginning," he tells himself. The advice seems to work for Jo, too.
She and Allison head for Dr. Stefano's lab. Jo asks him if his system could have been compromised when the spectrometer was stolen, and Stefano says no way -- his system, which he is under enormous pressure to complete and perfect in very little time -- works perfectly! Jo says that's funny, since it said her DNA was in the infirmary when she was sleeping at the Carters'. "I heard you were Frenching Fargo," Stefano smirks. Wow, word really does get around in Eureka. Jo denies that was her, and now she actually has proof: SARAH confirmed that Jo was sleeping in the living room all night. Okay, but who trusts her? She committed two counts of robocide last week! Stefano trusts his system over SARAH, but Allison does not, and demands that he show them the DNA readings of the person in the infirmary and the person sleeping at the Carters' last night. Stefano makes a "busted!" face and says that there was a little teeny-tiny anomaly he couldn't explain when Jo's DNA was scanned, but instead of trying to figure out what was going on, he decided to just keep going with the beta testing so he didn't lose his funding. Jo asks what the anomaly was, and Stefano says that she had two DNA signatures. He thought it was just a glitch, and yet still thought it would be a good idea to use one of the two DNA signatures to accuse Jo of a crime.
