Cameron"s figured out that Chrome Artie is still "alive," because in the grainy cell phone video shot from inside a car at night, she"s able to magnify a section of screen well enough to see Artie"s skull, eyes ablaze. Piece that with the news of a stolen shipment of coltan (which is a metal used to make Terminators even awesomer), and the Connor Crew gets the idea to attack Chrome Artie while he"s (they assume) vulnerable. Well, it"s John"s idea, and Sarah"s not wild about it. But he ignores her, and things go pear-shaped, since the one responsible for the coltan theft is not Chrome Artie (who"s still caught up in a totally different show: Extreme Terminator Makeover, forcing a plastic surgeon to make him look like some poor schmuck who leaves half-eaten Hot Pockets around the house). But since there is enough coltan to make 500-plus little baby Terminators, John wants to, you know, be a hero and destroy it, or get rid of it.
Only he winds up getting himself accidentally kidnapped, and gets taken to the future site of a Terminator factory (Cameron"s own birthplace, actually!), and locked inside a blast shelter with a sleeping Terminator standing sentinel. John has to get the key to the blast doors from around the dormant Terminator"s neck. He does it, which is one more reason why he"s the future leader of the human resistance and I"m not: if I had to do that, there would have been a lot more pants-shitting. The doors open; Cameron fights the new guy, wins, and locks him inside the blast shelter; and they dump the coltan in a lake (except for one piece that Cameron takes with her, which could be her parents, after all).
Meanwhile, Ellison is still trying to piece together all these murder scenes with crazy not-blood blood. He"s being completely undermined by one of his colleagues, who I"m guessing will turn out to be a Terminator from the Office Douchebag series.
