The Council of Sages discusses the Nirvash's immense display of power and how it is connected to Adrock Thurston--Renten's father. Meanwhile, Renton joins Gekkostate to get closer to Eureka, only to find himself at the bottom of the organization.
Eureka's "kids" pull a series of pranks on Renton, dead-set on keeping anyone from getting too close to the woman they call "Mama." Meanwhile, Renton goes out on a dangerous mission without authorization from the rest of Gekkostate.
The Vodarac priest that Holland rescued manages to remove the scub from Eureka's body, but the ordeal won't be without scars. Meanwhile, Renton tries to come to terms with the death and destruction he's caused since joining Gekkostate.
On his first mission with the Beams, Renton is faced with a difficult decision concerning the fate of a Vodarac girl. On the Gekko, Holland tries to avoid talking to Eureka about Renton, but he won't be able to avoid the subject forever.
Holland's quest to find Renton hits a snag when the Gekko runs into a military fleet preparing to take on the ship. Unable to wait, Eureka leaves to search for him on her own--but Renton might be closer than she thinks.
Gekkostate attacks the capital in order to rescue Norb, but Eureka's unwillingness to take any more lives hinders the operation. Colonel Dewey is quick to dismiss the assault, not knowing that Holland has succeeded in finding Eureka a partner.
Newly rescued Norb insists on returning to the Vodarac homeland, Eureka worries about improving her physical appearance, and Holland tells Renton about his first love--someone Renton knows all too well.
A misunderstanding between Renton and Eureka leads to awkwardness for the rest of the Gekko's crew. Meanwhile, Dewey continues his crusade against the Sage Council, and Stoner tries to improve public perception of Gekkostate through Ray=Out.
Eureka, Renton, and the kids finally make it to Earth, but have no idea what to do once they're there. Meanwhile Dewey takes Anemone to a celebration and tells her about his childhood and past with Holland.
The fate of the world is at stake as Eureka begins to turn into the next Scub Control Cluster. As an army of Coralians surround her, Renton understands that to save Eureka and everybody else, he might have to forsake his humanity.
