Queen Boudicca's daughter wants to help the Sparticles fight against Queen Kylie but she urgently needs to return to her own dimension to fight the Romans. Serena, Reese and HoloDora send Bua home, to Sadiq's dismay, of losing their fifth sensitive, and to Aris' annoyance that Reese did not allow him to help send Bua home. Serena and Ernesto take Fizzy and Byran's jeep (which the Fisher tribe stole the keys for) and part ways which they go to the citadel to rescue Orion, while Sadiq and the others search for the sixth sensitive.
