“Phased and Confused” is episode six of season three of Eureka.
Thorne has managed to get Zane to solve the cryptex and opened the underground bunker she’s been looking for. When the bunker opens, another door also opens into it from the basement under Zoe’s school. So she and a couple of friends go exploring it – only to end up trapped inside, along with Zane.
Above ground, Carter’s sister Lexi seems to have attracted the attention of a superhero, whose powers come from various experimental gadgets. More Iron Man than Superman in nature. When Carter asks Allison what Global Dynamics employees would want to be a superhero, she gives him a simple answer – all of them. Which doesn’t exactly narrow down the suspect list.
It’s still not known what purpose the bunker served, or why Thorne was looking for it.
