“Ship Happens” is episode fourteen of season three of Eureka.
At the end of the previous episode, “If You Build It…”, the ship that was the source of the mysterious signal had landed at the improvised platform that had been built outside the town from bits and pieces picked up from around the place. When it did, Henry approached it and rubbed a patch clear, revealing an American flag.
It turns out that Henry built the ship, which was an unmanned deep space probe launched 20 years previously. After all trace of it vanished 3 years later, the program was scrapped and the team disbanded. The project was the one in which Henry met Kim, who finally died in “Once in a Lifetime”. At this point, when a figure appears from the supposedly unmanned probe, it’s not a great surprise when it turns out to be Kim.
It’s not actually Kim, but the ‘child’ of the probe’s organic computer. Meanwhile, Carter has to return all the stuff that was used to build the landing pad, which doesn’t go smoothly. Then someone gets fried by electrocution, and weird electrical anomalies start cropping up.
