Episode Recap

The episode begins in space when Yuji and Marlene circle around the health space station covered by laser protection.
They manage to enter and land through a narrow aisle to the docks.
The sight is terrible - among the first to be found in the gelatinous green slime is the body of Councellor Victor. Bodies, guts, blood and parts of the Blue float in space.
Their shock is nothing compared to the terror they see in the face of Soo - she crawls out from under cover behind the slime, blood-covered and completely out of her mind. Seeing Yuji she utters thoughts of inevitable death to all "we will die all".
Marlene recognises it is not Soo, in fact, but the Councellor Lu Ling.
Some battle sounds ensue from the empty corridor.
After a blast the familiar voice is heard and Ricks enters "it is better to fight with a proper gun, isn't it?" This reunion gives all some light of hope, especially if the real Soo is in fact with Rick. The two twin sisters greet and hug affectionately relieved to find each other alive.
The small troop goes on.
After a brief meeting, Yuji and Marlene decide to go stop Tony and ride away on a bike - Rick, swayed by his obligation to Marlene follows them on a speeder. While Soo and Lu with a handful of soldiers attempt to flee the station and to disengage the habitation sector meanwhile.
Yuji and Marlene get lost along the way - and in an instant they are overwhelmed by the Blue.
Luckily, escaping from the maze they manage to lock themselves in a library room in the very last moment - Yuji performs a James Bond-like slide with the bike.
The other group also face the Blue. They race into a large open space (reminding of the interior of the Death Star in Star Wars) pursued by the Blue. Lu has the key access to all doors - in closing the very last one before the control station, one soldier doesn't manage to enter inside - a desperate last wave of shots is heard inside before a final cry (very intense for the remaining soldiers - they're shown desperate behind the closed door)
Lu manages to takeover the manual commands over the critical habitation sector.
Tony, meanwhile, is fully in control of the main computer room and succeeds in overriding all blocked access to engines. The health space station slowly gets into motion and aims for the Second Earth.
In the final scene, back in the Library, Yuji notices a familiar shadow. It is Alicia!
But her blank stare tells no good story - Marlene immediately recognises Alicia is under the influence of the B-cells.
Alicia draws her gun in a sudden move and starts shooting at Yuji. Marlene leaps and saves him in a valiant move, but a bloody hit smears her right shoulder. Rick immediately gets under cover, but Yuji yells and stops everyone from firing at Alicia.
"We are human" he tries to explain to Alicia despite Marlene crying it is to avail because once in the B-cell mode, the Sleepers don't listen. Yuji doesn't give up because he realises Alicia's fate is very much his own.
Yet Alicia faces him still with the gun. In brief moments, she finally reveals what happened during the second raid. Tony and Alicia appear in the very core of the nest, Tony looking very much like the god of the Blue - the bugs retreat by his determined stare - and there's is something in Alicia - the human, the hope inside - being broken by the insistance of the destiny proposed and understood by Tony.
"We are the new leaders" Alicia whispers as if praying, and continues "they woke me up, and I wanted to cry, and they didn't let me". This explains the feelings of Tony and Alicia ... "I felt so alone".
Yuji insists on Alicia not to give up fighting ... and as he approaches her, her words get even softer.
Rick shouts and warns there are Blue all over the top deck, watching down the windows at this scene.
Alicia then notices Marlene. "But you Yuji always liked Marlene, isn't it?" Alicia uncovers her unfilled feelings for Yuji that have gone bitter "I hate you Yuji!"
The glass shatters and the Blue fall in and onto the heroes. Frantic shooting, Rick and Marlene succeed in eliminating the threats - one Blue attacks suddenly and cuts Rick severely by its claws. "Please, just get through it" Marlene whispers.
Alicia yells fuelled by her sorrow "I hate you Yuji, you will all DIE!!!" and draws Yuji's dagger and wields in the air! She hesitates. Marlene locks her promptly by her laser pointer.
Rick shouts "Get her, Marlene!" and at the same time, Yuji, steps in the way "No!"
In the slow-motion of the moments, a shot is heard and Alicia breaks down like a cut tree. Marlene is shocked, it is Rick who fired. Yuji cries out loud.
