Jack and Henry are searching tirelessly for Allison and the rest of the Astraeus crew, but when Senator Wen calls off the search, Kevin is the one who goes to desperate measures. He steals some particle detectors from an unsuspecting scientist and starts to build a strangelet detector – a device that could pick up the energetic path left by the Astraeus. When Jack finds out that Kevin stole top-secret devices, he orders them returned at once, despite Kevin's protestations that his device could find the crew.
And in the virtual Eureka, a dragon is hatched out of the Astraeus, making everyone's logic meters go haywire. They manage to catch the dragon with a plasma net, but not before Allison and Holly both see it de-rez to a computer-generated sketch for an instant. It leaves a nasty scratch on Holly's arm, thereby convincing her it's real, but later that day, she notices the wound disappear, then reappear.

Welcome to Eureka, a seemingly normal small town somewhere in the Pacific Northwest. But you won't find it on any maps outside of the Pentagon. And if you're here you must be a genius. Because everyone else in town is.
