At the end of the last series, John Crichton and Aeryn Sun had been crystallised by an Qujagan scout ship. D'argo, Chiana and Rygel were powerless to help with Chiana being blind. Sikozu Svala Shanti Sugaysi Shanu left with Scorpius to rule the Peacekeeper force. John and Aeryn are returned back to their human state. Grayza, although she's been disposed of her power and command, she is back to cause problems for John and Scorpius. Sikozu has a new hairstyle, don't know what she thought was wrong with the old one. This ones reminiscent of the eighties punk movement. Aeryn is pregnant but is not going to giving birth in this series.
Apart from Commandant Mele-On Grayza and Scorpius, John will have to deal with another Peacekeeper captain. There's also going to be a new alien race, this time on the Peacekeeper side. Luxans are more prevalent in this series than before, D'argo won't be the only one this time round. Most important is that there's a full scale war between the Scarrans and the Peacekeepers and the crew of Moya just want to stay alive... If you was hoping to see Sikozu and Grayza in the same outfits that they wore in the last series, you'll be sadly disappointed. Both women have covered up, probably in response to complaints from certain quarters of the viewing public.
