Carter spends the opening minutes showing that he's a Luddite, as he's oblivious to important town functions because he doesn't read his e-mail, and he's skeptical about the new self-driving system known as Smart Asphalt. But when missiles start exploding in the sky (because of GD's planetary defense tactics), and Allison's all tense because an alien spaceship is due to arrive in about five days, e-mail's not a huge issue. Then property from all the residents goes missing, and great big peculiar pylons/plasma generators appear out of nowhere. Turns out that the "thieves" are the local teens, who are in trances and built these dangerous devices in their sleep. It doesn't take a genius (though this town is lousy with them) to figure out that the activity is connected to the self-driving system. It does take all of GD and the local law-enforcement manpower to figure out if they should blow the alien ship out of the sky before its imminent arrival, or if they should blow up the sky and possibly burn the entire atmosphere in return. Zoe (when not walking around like a zombie) tells her dad that the ship is friendly, and when it finally lands on earth, Henry walks over, wipes off some grime and reveals an American flag.
Elsewhere in Eureka, Jo gets a new swanky car (and the show squeezes in a big old product placement) and Fargo's jealous since his clunker Tabitha would be a good candidate for that new government program. But when Fargo tries to ditch his vehicle, she retaliates like a jealous lover, and tosses him in the trunk (along with the irritating new owner), until Fargo finally realizes you can't just throw away something you love. So he compromises on throwing away the shell of the car, but keeping the old AI. Basically, cars are scary if you let them rule your life. Lesson learned.
Lexi is gone! Lexi is gone! Lexi is GONE!!! We can get some Carter-Zoe time again because Lexi is gone! A tired Zoe drives Carter, who lectures her about staying up too late. She says she didn't stay late - she was having an anxiety dream. Carter can't relate, as his dreams usually consist of baseball, global catastrophe courtesy of GD, and sometimes cake. Didn't he also have a dream where he went to work naked in another season? Zoe enjoys taking her hand off the wheel when she realizes how nervous it makes her father, and even takes both hands off the wheel and puts them over her eyes. He freaks out, but she tells him that the car is self-driving today, which he'd know if he read the town-wide emails about the new "smart asphalt" program. Zoe thinks this is great, showing that whoever wrote her dialogue this week hasn't been a teenager in a tragically long time. Zoe's car self-parks in front of Carter's office. She drops him off and sets off for school, where she hasn't been like all season. Good to see that Vince finally released her from her indentured servitude at Café Diem. Jo is outside waiting for Carter, who says automatic driving seems like a bad idea to him. Jo says a robot driver is better than a teenage driver. She's right, too. Why is Carter being such a weirdo about this? At the very least, self-driving cars mean that Tess won't be able to veer off to the side of the road and park next to a dimension whenever she feels the urge to pee.
With that, Jo shows off her new police car. We're supposed to think it's awesome because it's made by the car company who sponsors the show this season. I guess that's better than deodorant, but not by much. Not by much at all. Jo claims her new car is high-performance and perfect even though -- let's face it -- it's a freaking station wagon. Carter asks where his new car is, and it turns out that he won't be getting one due to his history of destroying a car almost every week. Jo says she put in a lot of work and time requesting this car, which Carter would know if he read the emails she sent him during the process. You know, if Jo claimed she was the daughter of an assassinated Nigerian diplomat who needed Carter's help in smuggling her secret fortune to the United States, I'll bet he would have read them then. Fargo pulls up in his beater to tell Jo how great her new car is. His car also compliments it, being sure to mention Jo's car's make and model. Fargo then has trouble starting his car up again, as it's just not reliable like Jo's. He finally gets it going, and Jo offers to take Carter out in her new wheels. "She drives like a rocket," Jo claims. Speaking of rockets, a real one flies overhead. No one thinks much of it until it explodes in mid-air.
