The season where they go to earth must be the most bizarre piece of television I've ever seen. People take the non-earthly origins of the crew in their stride, no, they don't even acknowledge it. I mean, just look at this episode summary:
The crew buy a house in Prime Ridge, using money from ATMs that 790 rigs for them. Xev's cooking is atrocious, Kai doesn't like his new fridge, and after a day they get bored of TV. Xev gets a job at CJD Meat Products as a counsellor (as a way to get sex), where she meets Cleesby. Stan reckons he's got a chance to get it on with the realtor, and her daughter Picolina gets in on the action. Kai starts running out of protoblood, gives druggies all the money, and starts acting as high as they are. Everyone is a gun wielding psycho, and the episode ends in a massive shootout; S.W.A.T ruins the lawn, bullet holes line the walls, Cleesby and Picolina decide sex is better than shooting each other, and the druggies take off in the moth, leaving the gang no option but to use the neighbor's car for a getaway.
