"We're all infected!" Henry says. He really is the bearer of good tidings this week, isn't he? Yes, the virus is spreading between humans through touch via their electrical impulses. Well then, I think Henry and Allison need to be wearing spacesuits if they're going to hang out with Carter, don't you? Just because he has it, doesn't necessary mean that they do - yet! Allison says step one is to seal off the town and quarantine it from the rest of the world so that the entire West Coast isn't the first to fall victim to the epidemic. Step two is to tell Eurekans to stay indoors, which probably won't prevent them from getting it at all but will make them feel like they have some kind of protection. Carter asks how long they have before the entire town is infected. Henry guesses about twelve hours. Carter remembers that Kim tested negative for the virus before, which means she must be immune to it. Henry says it's possible that the original computer wrote an immunity to the virus in its code when it created Kim to protect her from the same fate. Curing diseases and making organic computer people out of skin cells but not seeing fit to warn about said diseases or make a way for the information the organic computer people hold to be easily and quickly downloaded? That original ship's computer is a brilliant asshole.

Henry runs into Kim's room without his space suit on. Meanwhile, she's drawing triangles on the board. Really, though? What do triangles have to do with space exploration? Isn't it all about the data collected and not the physics that went into collecting said data? It's like going on an African safari and taking pictures of the plane that took you there and none of the animals! Kim asks Henry why he'd disregarding isolation protocol, and he says it's because they now know that Kim is not the source of the disease. "Are you sure? Sheriff Carter proposed a very logical and compelling argument," Kim says. Yeah, well, Sheriff Carter is a sheriff and Henry is a scientist. Who are you going to believe? "You might even be able to help us," Henry says. Wow, what a privilege - to help the people who locked you in a room full of whiteboards and accused you of murder. But Kim is ready to help, volunteering all the tissue samples Henry needs to find the cure for the virus. Henry proposes that she bring all of her tissue to him, because he wants to work with her on this. Kim is very happy about this. I still don't know how much of her is robot/computer and how much is human. I guess the original Kim's skin really dug Henry?
