Has the impossible happened? Can Gaia at last feel fear? Having been injected with a serum by her uncle, Loki, Gaia is now experiencing some strange emotions, but being unfamiliar with certain feelings she is not sure whether this is fear. Heather, on the other hand, is more than willingly to give up her own fear gene. Even though she is unsure whether or not she can trust Josh, when she is offered the chance to participate in an experimental protocol to supress the fear gene, Heather jumps at the opportunity. This is what she has always wanted - this is her chance - a chance to be like Gaia. Meanwhile relationships and alliances are shifting. Ed and Tatiana grow closer as Gaia pushes Ed further away. But the more Gaia learns about Tatiana and her mother, the more certain she is that she and her father are in danger. Until, that is, a startling revelation from Loki leaves her wondering whether she even knows who her father really is . . .
