Zane's back, and he has a five o'clock shadow. It looks terrible. Jo sneaks up behind him at Café Diem and they kiss and exchange merry quips while Fargo watches from afar, so jealous. It doesn't escape Zoe's notice, so she decides to point it out in an entirely inappropriate conversation for a minor girl to have with an adult man. Fargo claims that he's over his crush on Jo, and Zoe says there's someone out there for him. Back to Zane and Jo, she proudly tells him about her perfect test results, and he, of course, craps all over her, saying that no one is perfect. No, but you can get a perfect score on a test. People do it all the time. One time, in 8th grade science class, I got a 121/100 on a test, thanks to extra credit. Fargo sticks up for Jo when she and Zane take their conversation to right above him, saying if she isn't perfect then she's pretty darn close. He then takes off, and Jo tells Zane that she wouldn't mind if he was nicer to her. Zane sucks, so he just says that Jo can't be perfect when she clearly has a problem with hypersensitivity and over-reacting. Jo perfectly reasonably says that when people care about each other, they focus on the positives and not the flaws.

Jo is summoned back to GD for a demonstration of Dr. Stefano's DNA monitoring device along with Allison and Henry. Henry is still against it, saying that it should be a voluntary program and not mandatory to give up one's DNA and civil liberties. Why is Henry so surprised about this? Has he forgotten why Eureka exists in the first place? Does he really expect a top-secret government project to have privacy? Also, making the process voluntary is just stupid, because we all know that the only people whose DNA needs to be kept track of are the criminals who'll refuse to submit to the test for that very reason. With one vote for and one against the DNA monitoring, Jo has the deciding vote. She says security has to be more important than whatever liberal crap Henry's spouting today so she votes yes. The ayes have it, and Dr. Stefano allows Jo to be the first person to have her DNA scanned for the database. She steps into the ominous-looking scanning chamber while Dr. Stefano promises this will be painless and quick, which means it won't be. Sure enough, he turns on the device and it immediately sets about electrocuting Jo.
